Introduction

Contemporary trends in dog training suggest that emotions cannot be reinforced. This article will critically examine the traditional behaviorist approach alongside the contemporary neurocognitive perspective to elucidate the technical nuances of emotion reinforcement in dogs (and mammals in general), challenging the notion that emotions are impervious to such processes.

The traditional behaviorist framework posits that behaviors, rather than emotions, are the primary targets of reinforcement. According to this view, emotions are seen as byproducts of conditioning, secondary to observable behavioral changes. This perspective has historically guided dog training practices, focusing on modifying observable actions through reinforcement without directly considering the underlying emotional states.

Asserting that fear is not a behavior overlooks the broad definition of behavior in psychological terms, which includes both observable actions and internal states or responses. Fear, while often regarded as an emotional state, manifests through various behaviors, such as avoidance, freezing, or physiological responses, which can indeed be modified or influenced through conditioning processes.

As a different field, neuroscience offers a different perspective on understanding animal emotions by integrating insights from genetics, which reveal the hereditary aspects of emotional responses; neurobiology, which examines the brain structures and neural pathways involved in emotions; and cognitive science, which explores the processing and expression of emotions. It also suggests that emotions are not merely reactions to external stimuli but are also shaped by intrinsic factors such as genetic predispositions and cognitive evaluations. It posits that through understanding these complex interplays, reinforcement can indeed influence emotional states by altering the environmental and cognitive contexts in which emotional responses are elicited.

The adherence of some dog trainers to the belief that emotions cannot be reinforced may stem from several factors:

To clarify, while I possess a social and affective neuroscience background, it is not my primary area of expertise. My comfort level is limited to exploring neuroscience insofar as it is relevant to my practical work on animal behavior and training. I believe that we must concentrate on our respective areas of specialization and avoid overstepping our bounds, which has been a predominant tendency among dog trainers and dog training in general. My principal academic focus is ethology and human-animal studies, and my practical experience in animal training has been primarily with dog owners. My research aims to enhance my effectiveness and understanding in communicating with animals and people, as detailed in my book. This will be my sole article on the topic of emotions. Although I may update it as necessary, I do not intend to engage in further subjective or “ping-pong” discussions on this subject, especially in noisy environments such as social media.

I felt it was important to contribute to this subject by presenting the science found in academic literature rather than in dog training groups or courses. I will provide various perspectives, questions, challenges, references, and other resources to support your research and help you form an informed opinion. I will not present a definitive “truth,” as such an absolute does not exist. As discussed in this article, multiple theories and perspectives often exist on a single topic. Emotions are frequently discussed and sometimes exploited, with individuals even charging fees to share their insights—often without proper expertise. Reaching audiences can be challenging due to language and cultural differences, leading to misunderstandings and misinterpretations of terminology. Science does not offer absolute truths; therefore, trainers must step outside their comfort zones and critically evaluate their beliefs against credible sources rather than relying solely on social media groups or individuals.

Consulting and citing the relevant references individually is also necessary when challenging a viewpoint. Engaging in discussions about beliefs, addressing the messenger ad hominem, and dismissing the efforts to provide reliable information are counterproductive. This article aims to encourage a thoughtful and open-minded approach to these issues in the future. I hope you will engage with it proactively and be willing to assess the information presented critically.

 

Defining basic emotions

Charles Darwin was an early emotion researcher who explored whether basic emotions—fundamentally distinct and qualitatively different from one another—exist (fig.1). Basic emotions, if they exist, are categorized to simplify complex experiences, similar to how elements are classified in chemistry. However, it’s debated whether emotions fit this classification model. People tend to view emotions as separate categories, like happiness, sadness, and fear, possibly due to either inborn traits (as proposed by some researchers) or social construction (as suggested by Neimeyer, 1995). Researchers like Ekman (1994) and Panksepp (1994) have suggested criteria for identifying basic emotions, such as universality and distinct inborn expressions, though there is disagreement on which emotions qualify and how many there are.

Defining basic emotions in humans is a complex challenge, and this complexity increases when applying these definitions to non-human animals. Emotions are internal, subjective experiences that are not directly observable. As a result, researchers must infer emotional states from observable behaviors, facial expressions, and physiological responses (Shepherd, 2017).

Basic human emotions are commonly categorized into discrete, universally recognized types: happiness, sadness, fear, anger, surprise, and disgust. However, there is an ongoing debate about whether these categories are truly universal and distinct or whether they are better described as continuous dimensions or blends of more fundamental emotional states (Reevy et al., 2010).

The challenge of defining emotions becomes even more pronounced when considering non-human animals. Although some species, such as dogs and cats, have been extensively studied and exhibit clear signs of emotional states akin to human emotions, others, like insects and fish, have more limited behavioral repertoires, making it less clear whether they experience emotions in a manner similar to humans (Adolphs, 2018).

Moreover, identifying behaviors associated with emotional states in non-human animals does not necessarily equate these behaviors with human emotions. For instance, a rat’s freezing response to a predator may indicate fear. Still, it could also be a reflexive response to danger that does not involve emotional experience in the same way as human fear.

 

The Challenge of Approaches from Different Fields

The growing interest in neuroscience has sparked interdisciplinary discussions involving psychology, sociology, philosophy, and ethology. This presents significant challenges, especially when professionals from non-neuroscientific fields engage with neuroscientific concepts without a deep understanding of the underlying principles and methodologies.

One major issue in interdisciplinary discussions is the risk of misinterpreting neuroscientific concepts. Neuroscience involves complex methodologies, including neuroimaging techniques (e.g., fMRI and PET scans), electrophysiological recordings, and molecular biology. Without knowledge of these methods, key concepts can be oversimplified or misrepresented. For instance, the term “neuroplasticity” is often misunderstood, leading to misconceptions about the brain’s capacity for change and recovery from neurological conditions (Kolb & Gibb, 2014).

Another concern is reductionism, where complex behaviors and mental processes are reduced to simple neural mechanisms. This reductionist view can undermine the multifaceted nature of human experience, which includes psychological, social, and environmental factors. Such oversimplification can result in deterministic views of human behavior, failing to account for the interplay between biological and environmental factors (Damasio, 1999).

Integrating neuroscience with fields such as law, education, and marketing introduces ethical concerns, particularly regarding the misuse or misrepresentation of neuroscientific findings. For example, neuroimaging used in legal contexts to assess a defendant’s mental state can raise ethical dilemmas about interpreting brain data ((Roskies & Morse, 2013). The potential for “neuroessentialism,” where individuals are judged solely based on neural characteristics, risks dehumanizing people by reducing them to biological substrates (Farah, 2011).

These brief examples show how effective communication across disciplines is necessary for successful collaboration. However, jargon and discipline-specific language can create barriers to understanding. When neuroscientific concepts are discussed without adequate explanation, it can lead to confusion and miscommunication, particularly in collaborative research efforts where shared terminology and methodology are fundamental (Sperber & Wilson, 1995).

Anthropomorphism in Neuroscience

The field of neuroscience has made significant strides in understanding brain function and behavior. However, integrating multiple theoretical frameworks, particularly when addressing phenomena like fear, can lead to confusion and oversimplification. This examination highlights the challenges of mixing theories and the impact of anthropomorphism, such as the metaphorical use of terms like “fidget.”

Anthropomorphism and anthropodenial are two interrelated but distinct concepts that shape how humans interpret the emotional lives of non-human entities. Though they represent opposing cognitive biases, both concepts are pivotal in influencing our understanding and treatment of animals.

Anthropomorphism involves attributing human-like characteristics, emotions, or behaviors to non-human animals. Anthropodenial, on the other hand, refers to the denial of human-like characteristics, emotions, or behaviors in non-human animals. This cognitive bias can obstruct the recognition and appreciation of the complexity and diversity of animal emotions.

If a term like “fidget” is used metaphorically to describe a neural mechanism with human-like characteristics, it may lead to oversimplified and misleading interpretations (Gordon, 2008). Such anthropomorphism can create a false sense of understanding and hinder accurate scientific discourse.

Mixing theories and using anthropomorphic language can result in oversimplification, which is problematic in neuroscience’s intricate domain. The brain’s complexity and many factors influencing emotional responses necessitate a nuanced approach. Oversimplification, whether through theory mixing or anthropomorphism, can obscure the multifaceted nature of emotional processing and limit clinical interventions (LeDoux, 2012).

 

Do All Emotions Need to Be Expressed Physically to Be Considered Emotions?

The question of whether emotions must be expressed physically to be considered valid emotions invites a nuanced exploration into the nature of emotions and their expressions. Emotions encompass subjective experiences, physiological responses, and behavioral expressions. The James-Lange theory posits that physiological arousal precedes and constitutes emotional experience, suggesting that bodily changes are crucial to feeling emotions (James, 1884). Conversely, the Cannon-Bard theory argues that emotional experiences and physiological responses occur independently and simultaneously (Cannon, 1927). These theories indicate that while physical responses often accompany emotional experiences, they are not strictly necessary for the existence of emotions.

The distinction between emotional experience and emotional expression is essential in understanding whether physical expression is required for emotions to be valid. Emotional experience pertains to internal, subjective feelings, whereas emotional expression involves outward manifestations such as facial expressions and body language (Ekman, 1992). Research indicates that individuals can experience various emotions internally, even without physical expression. For instance, individuals with neurological conditions, such as those affecting facial musculature, may find it challenging to express emotions outwardly but still experience them internally (Hennenlotter et al., 2009). This evidence supports the notion that emotional validity is not contingent upon physical expression alone.

Philosophical views also offer critical insights into this discussion. Existentialist philosopher Sartre (1943) argued that emotions are deeply personal and subjective, not fully captured by external expressions. According to Sartre, the essence of an emotion resides in the individual’s internal experience rather than its outward manifestation. Similarly, Merleau-Ponty (1962) emphasized that while physical expressions can enhance communication, they are not necessary for the existence of emotions. From these perspectives, the internal experience of emotions holds primacy over their external expression.

Neuroscientific research has identified specific neural circuits associated with emotional experiences, such as the amygdala’s role in processing emotions like fear and anger (LeDoux, 1996). Studies demonstrate that emotions can be experienced without physical expression, reinforcing the idea that emotions are not solely dependent on outward manifestations.

Sociological perspectives highlight that cultural norms and social contexts shape emotional expression. For example, cultural expectations can influence how and when emotions are outwardly displayed, indicating that physical expression is culturally contingent rather than universally required (Hochschild, 1983).

In clinical psychology, cognitive-behavioral therapy (CBT) emphasizes the importance of understanding and processing emotions internally, regardless of their physical expression (Beck, 2011). This approach supports the notion that emotions are valid and meaningful even without physical manifestation.

The interplay between sensory processing and emotional experience can also be useful in this discussion. Sensory processing involves the detection of stimuli through senses such as sight and touch, which are then interpreted by the brain to form emotional responses (Schacter & Singer, 1962). Physical sensations, such as warmth or texture, can evoke emotional responses and illustrate the connection between physical sensations and emotional states. Perception also shapes emotional experiences by interpreting sensory inputs based on past experiences and beliefs (Neisser, 1976). Damasio’s concept of somatic markers illustrates the interplay between physical sensations and emotional experiences. Somatic markers are bodily sensations associated with emotions that guide decision-making and influence emotional responses (Damasio, 1994). This interplay highlights the importance of understanding emotions as encompassing physiological and emotional dimensions, though it does not imply that physical expression is necessary for validity. Therefore, the assertion that all emotions must be expressed physically to be considered valid is a reductionist perspective that overlooks the complexity of emotional experiences.

 

Panksepp’s Theory in Dog Training

In recent discussions about dog training methodologies, I’ve observed a growing trend of positioning Jaak Panksepp’s theory of affective neuroscience as the sole acceptable framework for discussion. This trend has led to the rejection of alternative perspectives, even those from credible authors with differing views. During a brief exploration of social media, it became evident that proponents of other theories are often met with skepticism or outright rejection.

My review of various neuroscientific encyclopedias revealed that Panksepp’s work is not extensively referenced within the broader field of neuroscience (Della Sala, 2020; Ray, 2024; Reevy, Ozer, & Ito, 2010; Shepherd, 2017). This absence might reflect a more nuanced understanding of emotional processes that are not fully captured by any single theory. It makes sense because the study of emotions, such as fear, encompasses a range of perspectives. For instance, Adolphs (2013) highlights at least nine distinct views on fear, each contributing to a more comprehensive understanding of emotional responses.

Restricting our focus to a singular theory, such as Panksepp’s, poses risks akin to those observed in past debates. I often give the example of the discussion on the “theory of dominance” in dog training, which was once widely spread and debated with Mech’s work being always referred to, but later revealed to be a misinterpretation of Mech’s work, as he clearly confirmed that people misunderstood his writings (Barata, 2012). Panksepp’s work, too, is being similarly isolated and potentially misapplied. The current trend of treating Panksepp’s theory as the definitive approach overlooks valuable insights from other perspectives and limits our understanding of canine behavior, leading to more subjective assumptions and pushing us even further away from what we can observe and measure, which is already complex.

The term “affective neuroscience,” popularized by Jaak Panksepp, refers to the interdisciplinary study that integrates the examination of emotions (affect) with neuroscience to elucidate the neural mechanisms underlying emotional processes. Panksepp’s work in the early 1990s established this field, focusing on the emotional systems in animals and their neural correlates. His identification of seven primary emotional systems—SEEKING, FEAR, RAGE, LUST, CARE, PANIC/GRIEF, and PLAY—aimed to provide a foundational framework for understanding the neurobiological bases of behavior (Panksepp, 1998, 2005).

The study of emotions and their neural correlates has earlier theoretical foundations laid, for instance, by psychologists and neurologists such as William James and Carl Lange in the late 19th century, who proposed physiological bases for emotions. Subsequent advancements in the mid-20th century included James Papez’s formulation of the Papez circuit, which mapped a neural circuit involved in emotional expression, and Paul MacLean’s expansion of the limbic system concept. The research of the 1960s and 1970s further refined our understanding by exploring specific brain structures like the amygdala and their roles in emotional processing (LeDoux, 2012).

Despite Panksepp’s significant contributions, several limitations of his theory become apparent, particularly in the context of practical applications such as dog training. Firstly, Panksepp’s model tends to oversimplify the complexities of canine behavior by focusing on primary emotional systems, potentially neglecting the multifaceted interplay of cognitive processes, environmental influences, and learned behaviors. This simplification contrasts with cognitive learning theories, such as those proposed by Pavlov and Skinner, which emphasize the role of reinforcement, punishment, and associative learning in shaping behavior (Pavlov, 1927; Skinner, 1953).

Panksepp’s theory has also been critiqued for its insufficient consideration of behavioral ecology and ethology, which examine natural behaviors within ecological contexts and emphasize species-specific adaptations. Additionally, the theory’s failure to account for individual variation and breed-specific behaviors can lead to less effective training strategies, as dogs exhibit significant diversity due to genetic and selective breeding factors (Shettleworth, 2010).

Panksepp’s dualistic perspective, which separates mind and body, may further constrain the applicability of his theory. While historically significant, this dualistic approach may limit the acceptance of integrative models that combine cognitive, emotional, and contextual factors (Damasio, 1994; Rolls, 2013). Additionally, Panksepp’s research methodologies, which often involve invasive procedures, raise ethical concerns about the balance between scientific inquiry and the welfare of the animals studied (Panksepp & Biven, 2012).

Furthermore, Panksepp’s focus on subcortical emotional systems might overshadow the role of higher cognitive functions located in the neocortex. Cognitive processes such as reasoning, problem-solving, and memory play important roles in how dogs learn and interact with their environment (LeDoux, 2012; Barrett & Satpute, 2013). For example, claims that dogs lack cognitive coping mechanisms for stress simplify their complex behavioral and cognitive responses.

Contrary to this view, evidence shows that dogs possess sophisticated cognitive abilities that aid in managing stress. Research has revealed that dogs are capable of cognitive processing beyond mere instinctual reactions. Training provides further evidence of dogs’ cognitive abilities. Through training and conditioning, dogs learn complex tasks and adapt their behavior based on specific signals. This process involves memory and problem-solving skills. Miklosi (2007) demonstrates that dogs can engage in problem-solving, memory, and learning, which are crucial for handling stress. These cognitive skills imply that dogs use more than just basic responses to cope with stress. Dogs also exhibit significant behavioral flexibility in response to changing environments, indicating cognitive processing. They can adapt their behavior based on new experiences and information. For example, dogs can modify their actions in response to altered circumstances, like age, reflecting their ability to adjust their coping strategies (Wallis et al., 2013). This flexibility suggests that dogs employ cognitive mechanisms when dealing with stress.

Comparative research supports the view that domestic mammals have advanced cognitive functions. This research on the five sociocognitive abilities of domestic mammals shows that some species can recognize us or detect and interpret human emotions or signals (Jardat & Lansade, 2021). These findings challenge the idea that non-humans rely solely on instinctual responses. The emotional lives of dogs further illustrate their cognitive coping mechanisms. Dogs experience emotions such as stress and anxiety, which influence their coping strategies. A study of dogs’ emotional responses, including their capacity for empathy and stress management, supports the argument that cognitive processes are involved in their coping mechanisms (Bradshaw, 2011). Observations of dogs in natural settings provide additional insights into their stress-coping strategies. Dogs employ various coping behaviors, such as seeking comfort or changing their actions in response to stressors. These behaviors suggest that cognitive strategies affect how dogs handle stress and adapt to their environment.

As a final note, I want to mention that critical neuroscience examines the intersection of cognitive neuroscience with broader philosophical, cultural, and social contexts. It challenges the reductionist view that the mind can be fully explained by brain functions alone, advocating instead for a more holistic understanding that incorporates the dynamic interactions between neural processes, the body, and the environment. This perspective also critiques how neuroscience is sometimes employed ideologically to support or justify social and economic structures, such as flexible capitalism. Critical neuroscience seeks to expose how scientific “facts” are constructed and urges a more nuanced and reflective approach to understanding the mind and brain (Choudhury & Slaby, 2011).

 

What is “Reinforcement”?

Reinforcement is the process of strengthening or increasing a behavior through a stimulus. There is a tendency to associate reinforcement only with operant conditioning. Skinner did not introduce the concept, even though he defined it precisely. Hull, Watson, and Thorndike had already mentioned reinforcement as a stimulus that increases a response. Arguing against the perspective that reinforcement should be exclusively associated with operant conditioning requires a nuanced understanding of learning and behavior modification principles. At its core, reinforcement is about increasing the likelihood of a behavior or response through stimuli, a principle not limited to the deliberate manipulation of outcomes as seen in operant conditioning.

Furthermore, the argument that reinforcement should be an exclusive term for operant conditioning overlooks the adaptive significance of learning and physiological mechanisms. Both classical and operant conditioning have evolved to help organisms learn from their environment in ways that enhance survival and reproduction. In terms of mechanism and applicability, the concept of reinforcement is fundamental to understanding how organisms adapt to their environments. Therefore, limiting the concept of reinforcement to operant conditioning, as widely read in social media, is inaccurate and neglects the complexity and diversity of learning and behavior modification mechanisms.

Classical conditioning, a learning process first described by Ivan Pavlov, involves the association of a neutral stimulus with an unconditional stimulus to elicit a conditional response. In this framework, the unconditional stimulus (US) naturally triggers a response, while the conditional stimulus (CS) is initially neutral but becomes associated with the US through repeated pairings. For example, in Pavlov’s famous experiment, the sound of a bell (CS) was paired with the presentation of food (US), leading to the dogs salivating (conditional response, CR) at the sound of the bell alone.

Some researchers extend the concept of reinforcement to classical conditioning. In this context, the US can be viewed as a reinforcer because it strengthens the CS and CR association. When the US is presented following the CS, it reinforces the learning process by providing a meaningful outcome that the organism learns to anticipate. For instance, when the bell is rung before the food is presented, the food serves as a reinforcer that solidifies the connection between the bell and the salivation response. This reinforcement is necessary for establishing the conditional response, as it helps the organism learn that the CS predicts the arrival of the US. However, it is important to recognize that classical and operant conditioning terminology and concepts are distinct. Classical conditioning focuses on the association between stimuli, while operant conditioning emphasizes the role of consequences in shaping behavior. Using the term “reinforcer” in classical conditioning can lead to confusion, as it blurs the lines between these two fundamental learning processes.

Classical conditioning also involves the modification of behavior. The process of pairing a neutral stimulus with an unconditional stimulus to produce a conditional response can be seen as reinforcing because it increases the likelihood of the conditional response to the previously neutral stimulus (Olson, 2016). Moreover, the distinction between classical and operant conditioning is not always clear-cut in real-world learning scenarios. Many behaviors are influenced by a combination of associative learning and the consequences of actions, suggesting that reinforcement operates along a continuum rather than within strictly defined categories. For example, the development of phobias can be explained through classical conditioning, but the maintenance of avoidance behavior can be reinforced operantly by the relief it provides, demonstrating the interconnectedness of these learning processes.

The original Russian term used by Pavlov that corresponds to “reinforcer” is “подкрепление” (pronounced “podkreplenie”). This term is often translated as “reinforcement” in English. While Pavlov’s work laid the foundation for concepts related to reinforcement in behaviorism, he did not extensively develop these ideas in the same way other psychologists would later explore them. Instead, his focus was primarily on the mechanisms of classical conditioning and the associations formed between stimuli and responses. As it is understood today, the concept of reinforcement was not a primary focus of Pavlov’s terminology or theoretical framework. However, the term “подкрепление” is indeed associated with his research on conditional responses and learning processes.

Pavlov used the term to describe the strengthening of an already-learned but weakening response, not the modern definition of selecting and strengthening new behaviors. Although the widespread use of the term reinforcement in learning theory is traceable to Pavlov’s influence (1927), he was not himself a reinforcement theorist in the sense that came to be accepted in American psychology. He identified reinforcement with the occurrence of the unconditional stimulus and its elicited response. Key terms like “reinforced” and “reinforcement,” which now serve as the approved labels for the central concept in our discipline, arose largely by accident. They are universally, and in a sense, correctly attributed to Pavlov (1927/1960), but in the historical compendium of his addresses published in 1928, the word “reinforcement” appears only once and then as a rather loose translation of the original Russian text (Razran, 1955). According to Razran, Pavlov and his students he has never used the term “reinforcement” for the trials preceding the full-fledged emergence of the CR. In the more systematic series of lectures published in 1927, Pavlov often used the notations “reflex reinforced” or “stimulus reinforced” in the trial-by-trial protocols for individual experiments, but “reinforcement” never appeared as a theoretical concept. It was used to describe the practice of reinvigorating the conditional salivary secretion after it had been weakened by repeated elicitations by presenting one or more trials where the original unconditional stimulus followed the conditional stimulus. If the unconditional stimulus was not presented on a given trial, the effectiveness of the conditional stimulus declined, and the trial was classified as one of extinction, another term apparently borrowed directly from a common language.

Some argue that the acquisition of conditioned responding should be broken down into components, including the point of acquisition and the asymptotic response magnitude (Gallistel, Fairhurst, & Balsam, 2004). Generally, increasing US intensity or number tends to increase the magnitude of conditioned responding (Mackintosh, 1974, pp. 70-71). However, although Morris and Bouton (2006) detected effects of US magnitude on the point of acquisition in aversive and appetitive procedures with rats, the extent to which US magnitude influences the point of acquisition is still unclear. Unlike US intensity, the effects of increasing US duration are not consistent across procedures (Mackintosh, 1974).

Perhaps some of these terms are lost in translation or mixed with Tolochinov, Vurfson, Babkin, Boldyrev, or Kashereninova’s work (Windholz, 1989). For instance, many English-language textbooks use terms like unconditioned stimulus” and “unconditioned response.” These terms originated from translation errors when Pavlov’s original Russian terms (conditional, not conditioned) were translated into English (Fitzpatrick, 1990; Goldman, 2012). Reinforcement is a term that can mean many things in both its technical and nontechnical usage. It always involves something related to strengthening, but even in lay language, it can legitimately refer to the act of strengthening, the state of being strengthened, or the thing that strengthens. In its technical use in psychology, reinforcement has been employed in all these senses and many other specialized ones. For example, in the dictionary of psychological terms compiled by English and English (1958), two and a half pages are required to list and describe the various usages. They cover nine psychological meanings of the term “reinforcement” and 32 separate entries of its various combined forms, such as aperiodic, primary, and serial reinforcement. They prefer the usage based on the Pavlovian paradigm: “the natural occurrence or the experimental presentation of the unconditional stimulus along with the conditional stimulus; or the strengthening of the conditional response relationship thereby.” For the remaining special meanings with enough operational specificity to be useful, English and English recommend using alternate words such as facilitation, reward, drive or tension reduction, confirming reaction, and goal attainment.

You can read more about it in the following references: Dinsmoor (2004), Pavlov (1960), Rescorla & Wagner (1972), Schoenfeld (1978), Schoenfeld (1995), Windholz (1989), and Yokoyama (2023).

 

Mechanisms of Reinforcement

As mentioned above, the term “reinforcer” or “reinforcement” generally refers to something that enhances or strengthens a behavior. However, the mechanisms of reinforcement vary across different disciplines. Although the core idea of reinforcement as a means to strengthen behavior remains consistent, the interpretations and mechanisms can vary across disciplines due to their distinct focuses. Each field may define and interpret these mechanisms differently, focusing on distinct processes or principles that underpin how reinforcement operates within that domain. Therefore, the specific mechanisms of how each field’s particular theoretical and empirical frameworks shape reinforcement functions.

 

Neuroscientific Perspective

In neuroscience, reinforcement is closely linked to the brain’s reward circuitry, which involves several key structures, including the nucleus accumbens, ventral tegmental area (VTA), and prefrontal cortex. “Reward circuitry” refers to the network of brain structures and pathways involved in processing rewards, motivating behaviors, and reinforcing learning. This circuitry is vital for survival, as it helps organisms seek out and repeat beneficial behaviors, such as eating, mating, and social interactions. The reward circuitry is heavily implicated in the experience of pleasure, motivation, and reinforcement learning. Mechanisms include:

Neural Mechanisms of Reinforcement

The brain regions involved in reinforcement processes are part of the reward circuitry:

B-D) Activation of the amygdala towards the CS is observed bilaterally after fear conditioning (b) and observational fear learning (c) and unilaterally (d) in the left amygdala after instructed fear. From Olson et al. (2007).

 

Limbic System Involvement

Neurotransmitter Systems and Hormones

Neural Plasticity

Repeated emotional experiences can lead to neural plasticity, where the brain’s structure and function are modified, reinforcing specific emotional responses. This is evident in phenomena like fear conditioning and habituation (see images below).

Synaptic Strengthening

Synaptic strengthening, or long-term potentiation (LTP), is a process where repeated stimulation of a neural pathway increases the strength of synaptic transmission. This mechanism is crucial for learning and memory and applies to emotional learning as well. Emotional experiences can lead to LTP in neural circuits associated with emotion, reinforcing these emotional responses.

Neural Circuits and Feedback Loops

The brain operates through complex neural circuits and feedback loops that involve cortical and subcortical regions. The prefrontal cortex (PFC), which is involved in decision-making and moderating social behavior, can regulate the emotional responses generated by the limbic system. Through top-down regulation, the PFC can reinforce or inhibit emotional responses based on past experiences and cognitive appraisal of the situation.

Emotional Reinforcement

Emotions themselves can act as reinforcers. For example, pleasure from social interactions can reinforce social behaviors, while discomfort from fear can reinforce avoidance behaviors. Emotional reinforcement is integral to learning from our environment and experiences, shaping our future behaviors and emotional responses.

Behaviorism Perspective

Behaviorism, particularly as articulated by B.F. Skinner focuses on observable behaviors and the environmental factors that influence them. Mechanisms of reinforcement in behaviorism include:

In the context of behaviorism, I want to mention active and vicarious learning in shaping and reinforcing emotional responses. Active learning involves direct engagement with experiences that evoke emotions, such as through expressive arts or role-playing. This approach allows individuals to confront and express their feelings, reflect on their emotional experiences, and receive feedback, thereby enhancing emotional awareness and resilience. Conversely, vicarious learning involves learning about emotions through observing others. By witnessing how others handle emotional situations—through stories, films, or real-life interactions—individuals gain insights into managing their emotions and internalizing social norms regarding emotional expression. This type of learning also fosters empathy, helping individuals connect more deeply with others.

Expanding on the Behaviorist Approach

 

Ethology Perspective

Ethology, the study of animal behavior in natural environments, provides insights into the evolutionary significance of reinforcement. Mechanisms include:

Ethology also offers a robust framework for comprehending how behaviors are shaped by their associated costs and benefits. As a discipline focused on the study of animal behavior, ethology underscores the necessity of assessing the outcomes of actions through the perspective of net value.

A central concept within ethology is the Net Value of Behavior (BNV), which is defined as the difference between the benefits (B) and the costs (C) associated with a behavior. This relationship is mathematically expressed by the formula: BNV = B – C. A positive BNV signifies that the benefits exceed the costs, thereby making the behavior advantageous. Conversely, a negative BNV indicates that the costs surpass the benefits, rendering the behavior less favorable. When BNV is zero, the behavior is considered neutral, presenting no distinct advantage or disadvantage.

The frequency of a behavior (BF) is closely correlated with its net value, as represented by the equation BF = f(BNV). This implies that the probability of a behavior being repeated is directly proportional to its net value. For example, if an animal encounters a behavior that provides substantial benefits with minimal costs, it is more likely to re-engage in that behavior, thereby reinforcing the positive emotional response associated with it.

 

Merging Neuroscience and Behaviorism

Fig. 3. A neural model of non-social fear learning in humans. Connectivity is bidirectional, although the arrows point in one direction and describe the flow of information between different brain functional regions. Fear conditioning occurs by associating the conditional stimulus (CS) representation with the somatosensory representation of the unconditional stimulus (US). The lateral nucleus (LA), where CS and US converge, is the learning site. The amygdala receives information from the hippocampal memory system (Hipp), anterior insula (Al), and anterior cingulate cortex (ACC), which contains secondary representations of the CS and US (information about the learning context and the internal state of the organism. From Olson et al. (2007).

 

Fig. 4. In observational fear learning, the CS is modified by association with a representation of the distressed peer, serving as US. The hypothesis of CS and US representations converge in the LA. The strength of the US can be modified by MPFC input related to the mental interpretation of the other and the cortical representation of empathic pain through the ACC and the LA. From Olson et al. (2007).

 

Fig. 5. Fear-instructed learning occurs by modifying the processing of the visual representation of the CS through an abstract representation of the threat. Consequently, contingency is likely to rely heavily on the hippocampal memory system rather than being encoded in the amygdala. From Olson et al. (2007).

 

Integrated Emotional Model (IEM)

My suggestion on this topic introduces the Integrated Emotional Model (IEM) for animal training, a direct approach that emphasizes animals’ emotional, cognitive, and social complexities. This suggestion encourages a nuanced understanding of animal behavior, steering clear of anthropomorphism—the tendency to attribute human emotions and motivations to animals, leading to misunderstandings and misinterpretations of their actions and needs.

The IEM focuses on accurately recognizing and interpreting animals’ behavioral signals, a crucial skill for tailoring training to each animal’s unique circumstances and promoting their well-being. By carefully avoiding the pitfalls of anthropomorphism and grounding our practices in evidence-based understanding of animal behavior, the IEM offers a realistic, respectful framework for enhancing animal training, ensuring it is both effective and considerate of the animal’s emotional state.

In practice, the IEM challenges trainers and owners to be more attuned to the subtle nuances of animal behavior. It underscores the importance of creating training scenarios that are physically safe and emotionally supportive, allowing animals to learn and thrive without fear or distress.

The Integrated Emotional Model represents a forward-thinking approach to training that prioritizes the health and welfare of animals, paving the way for more humane and educated interactions between humans and the animals in their care.

Cognitive and Social Elements:

Neurobiological Insights:

Critical Thinking Models for Practical Analysis:

Systemic Thinking:

  1. Identify Interconnections: Understand how different aspects of the animal’s life, such as home environment, interactions with humans and other animals, and previous training experiences, influence their behavior and response to training.

  2. Holistic Approach: Develop training plans considering these interconnections, aiming for consistency across different environments and situations. This approach ensures that behaviors learned in training are transferable and stable across contexts.

Feedback Loops:

Critical Thinking:

  1. Question Assumptions: Challenge common beliefs about animal behavior and training methods. This could involve re-evaluating the use of certain reinforcers or punishments based on the latest research or the specific needs of the animal.

  2. Evidence-Based Decisions: Use scientific research and data to inform training practices. This means staying updated on the latest animal behavior and neurobiology studies and applying those insights to training methodologies.

The “Comfort” Discussion

To finish, I want to address this popular trend. The notion that emotions are immutable has been popularized, in part, by examples of comforting dogs in distress. This belief, appealing due to its emotional resonance and the desire to alleviate animal suffering, ironically can contribute to its proliferation. This trend continues despite contradicting the academic consensus, as shown in the documents and references below, and is propelled by social reinforcement and cultural survival mechanisms.

Many pet owners and trainers advocate the practice of comforting dogs during storms despite its contentious nature and extensive documentation in academic circles. Exploring neuroscience, learning theory, and canine behavior sheds light on the potential drawbacks of this approach. However, this discussion raises several challenging questions that warrant further exploration:

  1. How do people define comfort, and how do they apply it in various contexts? The subjective nature of comfort can vary significantly among individuals and cultures. What one person perceives as comforting may be distressing to another. This variability complicates the understanding of emotional responses and the appropriateness of comforting behaviors.

  2. What are the long-term effects of comforting behaviors on human and animal emotional development? While immediate comfort may alleviate distress, it is essential to consider whether such interventions promote healthy emotional regulation or inadvertently reinforce maladaptive behaviors. For instance, does comforting a dog during a storm help it cope with future storms, or does it create a dependency on human reassurance?

  3. How do societal norms and cultural beliefs shape our understanding of emotional expression and comfort? Different cultures have varying beliefs about emotional expression, which can influence how comfort is perceived and enacted. Understanding these cultural dimensions can provide insight into the broader implications of comforting behaviors and their acceptance within different communities.

  4. What role does individual temperament play in the effectiveness of comforting strategies? Just as humans have different emotional responses based on personality traits, dogs may also respond differently to comforting behaviors. Some dogs may thrive on reassurance, while others may become more anxious. How can we tailor our approaches to accommodate these individual differences?

  5. How do advancements in neuroscience inform our understanding of emotional responses in humans and animals? As neuroscience research continues to evolve, it offers new insights into the mechanisms underlying emotional experiences. How can this knowledge be applied to improve our approaches to comforting behaviors, ensuring they are grounded in scientific understanding rather than anecdotal evidence?

  6. What ethical considerations arise from the practice of comforting animals in distress? The desire to alleviate suffering is noble, but it is crucial to examine whether our interventions are genuinely beneficial for the animal’s emotional well-being. Are we prioritizing our emotional needs over the animal’s natural coping mechanisms?

Many pet owners and trainers advocate the practice of comforting dogs during storms despite its contentious nature and extensive documentation in academic circles. Exploring neuroscience, learning theory, and canine behavior sheds light on the potential drawbacks of this approach:

Ethological models also might provide a differentiated approach to understanding behavior by evaluating its net value—benefits minus costs—based on observable actions, as mentioned above (Ethology Perspective). This framework is particularly useful for analyzing behaviors like a dog’s response to storms and the subsequent comforting actions of an owner. For instance, when a storm induces fear in a dog, the owner’s comforting behavior can be assessed by quantifying observable benefits, such as physical comfort and perceived safety, against observable costs, such as the time spent and potential disruption to the owner’s routine. A positive net value indicates that the benefits of comforting the dog outweigh the costs, suggesting that this behavior will likely be repeated. Conversely, the behavior may become less frequent if the net value is neutral or negative, meaning the costs outweigh the benefits. Although ethology effectively captures behavioral patterns’ dynamics and consequences, it does not measure emotional experiences directly. Instead, it relies on observable actions and outcomes to infer the relative value of behaviors and their impact on future actions.

From a psychological perspective, the owner’s behavior can be understood through concepts such as attachment and emotional regulation. The owner feels a compelling urge to engage in comforting behaviors, driven by a desire to alleviate the dog’s visible distress. This need for comfort may stem from the owner’s own emotional discomfort in witnessing the dog’s fear, leading them to seek a sense of control and purpose in the situation.

It is important to note that in some cases, the owner benefits more from these interactions than the dog. For instance, when the owner comforts the dog during a storm, they might experience an emotional boost from alleviating their own feelings of helplessness or anxiety. This act of comforting can give the owner a sense of purpose and control over a stressful situation, potentially more than it alleviates the dog’s fear. This perspective shifts the focus from the dog’s needs to the owner’s psychological reinforcement.

I could use the term “empathy” here, but I won’t. The term “empathy” is often used in discussions about dog training and behavior, sometimes as a marketing trend. Although empathy suggests a deep understanding of another’s feelings, it can be misleading in the context of dog behavior. Owners may assume that their comforting actions are what the dog truly needs, but this assumption can overlook their individual coping mechanisms and emotional needs. This reliance on a superfluous concept of empathy in dog training can unintentionally neglect the dog’s ability to develop resilience. Instead of fostering independence, the owner’s comforting behavior may inadvertently reinforce the dog’s fearful behavior, creating a cycle of dependency. The owner, believing they are acting empathetically, may not recognize that their actions could hinder the dog’s emotional growth and ability to cope with stressors independently.

Additionally, the owner’s anxiety and need for reassurance can have a significant influence. In the face of a storm, the owner may experience heightened feelings of vulnerability and uncertainty. By comforting the dog, they channel their anxiety into nurturing actions, creating a temporary sense of control over the chaotic environment. This dynamic can lead to a cycle where the owner’s need for comfort becomes a coping mechanism, allowing them to manage their emotional discomfort while potentially neglecting the dog’s need to learn self-soothing strategies.

This situation can raise ethical questions about dependency and autonomy. The dog’s reliance on his owner for comfort during storms may foster a sense of dependency that complicates his ability to cope with fear independently. The owner’s well-intentioned actions, while rooted in concern, may inadvertently hinder the dog’s emotional growth and resilience. Seeking comfort or help is a common coping mechanism in response to fear. When an animal feels threatened or anxious, it often seeks proximity to a trusted figure as part of its fear response (e.g., Hennessy & Kaiser, 2006). This behavior is an aspect of social buffering, a well-documented phenomenon where social support mitigates stress responses in fearful situations (Hostinar & Gunnar, 2013). This paradox highlights the tension between the desire to protect and the necessity of allowing space for self-soothing and personal development.

Furthermore, the concept of existentialism comes into play as both the dog and the owner navigate their experiences of fear and anxiety. The dog’s fear of storms represents a fundamental aspect of existence—the confrontation with the unknown and the uncontrollable. The owner’s comforting behavior, while an attempt to mitigate this fear, also reflects their struggle with the unpredictability of life. In seeking to provide comfort, the owner grapples with their existential concerns, revealing the interconnectedness of their emotional states.

In conclusion of this topic, to provide comfort to dogs during storms, we need to maintain a balance between compassion and scientific understanding. It is important to consider the complicated emotional states of canines, the tendency for subjective assumptions, the tiny line of anthropomorphism, and the impact of human behavior on them. This will help dogs develop the skills they need to tackle challenges independently. We should move past simplistic notions of vulnerability and strive to develop a more resilient and informed relationship between dogs and their owners. Neuroscience supports the concept that emotions can be reinforced, indicating that comforting a dog during a storm might unintentionally reinforce fearful behavior. Whether comfort acts as reinforcement depends on the individual and the situation; not all individuals will perceive comfort similarly, and not all situations will lead to comfort acting as a reinforcer.
