Starting from the sensuous perception of what is seen, an attempt is made at re-casting a Husserlian theory of constitution of the object of intuition, as one leaves the natural attitude through a transcendental method, by positing several theses so as to avoid the aporias of philosophical binary oppositions such as rationalism and empiri-cism, realism and idealism, logicism and psychologism, subjectivism and objectivism, transcendentalism and ontologism, metaphysics and positivism. Throughout fifty-five theses on constitution, the Husserlian proposal of continuously reforming philosophizing (...) by transcendental reduction is revisited, leaving the latter incomplete as new conversions are required by noetic-noematic correlations between world and consciousness.

What triggers the execution of actions? What happens in that moment when an action is triggered? What mental state is there at the moment of action-execution that was not there a second before? My aim is to highlight the importance of a thus far largely ignored kind of mental state in the discussion of these old and much-debated questions: motor imagery. While there have been a fair amount of research in psychology and neuroscience on motor imagery in the last 30 (...) years or so, it is only recently that we start to understand the important role motor imagery plays in action initiation. And if, as these findings suggest, motor imagery plays an important role in action initiation, we can make progress not only in understanding action initiation in general but also in understanding what goes wrong in akratic actions and in relapse actions. Finally, this new picture of action-initiation also has far-reaching consequences for the relation between motivation and causation in naturalistic action-explanations. (shrink)

Diagnosing emotion disturbances should be informed by current knowledge about normal emotion processes. I identify four major functions of emotion as well as sources for potential dysfunctions and suggest that emotions should only be diagnosed as pathological when they are clearly dysfunctional, which requires considering eliciting events, realistic person-specific appraisal patterns, and adaptive responses or action tendencies. Evidence from actuarial research on the reported length of naturally occurring emotion episodes (including potential determinants) illustrates appropriateness criteria for the clinical evaluation of (...) emotion duration—an essential element in the DSM-5 symptom catalogue for major depression episodes, especially in bereavement. The need for more actuarial evidence on normal emotion responses and its consideration by the clinical community is highlighted. (shrink)

Cal Izard has provided psychology a robust vision of human emotional feelings. He has addressed the full spectrum of emotional-developmental-cognitive complexities entailed in clarifying seemingly impenetrable mysteries: How do we experience emotions and how do they guide cognitive development? Izard’s developmental studies of infant minds integrate the primal evolutionary affective foundations of our nature with the diverse paths of nurture, and are framed in ways that can promote human thriving. His multilayered vision of our emotional nature resonates well with modern (...) cross-species affective neuroscience perspectives. (shrink)

Emotional processing without conscious awareness plays an important role in human social interaction. Several behavioral studies reported that subliminal presentation of photographs of emotional facial expressions induces unconscious emotional processing. However, it was difficult to elicit strong and robust effects using this method. We hypothesized that dynamic presentations of facial expressions would enhance subliminal emotional effects and tested this hypothesis with two experiments. Fearful or happy facial expressions were presented dynamically or statically in either the left or the right visual (...) field for 20 (Experiment 1) and 30 (Experiment 2) ms. Nonsense target ideographs were then presented, and participants reported their preference for them. The results consistently showed that dynamic presentations of emotional facial expressions induced more evident emotional biases toward subsequent targets than did static ones. These results indicate that dynamic presentations of emotional facial expressions induce more evident unconscious emotional processing. (shrink)

Functional theories posit that emotions are elicited by particular goal-related situations that represented adaptive problems and that emotions are evolved features of coordinated responses to those situations. Yet little theory or research has addressed the evolutionary aspects of these theories. We apply five criteria that can be used to judge whether features are adaptations. There is evidence that sadness, anger, and anxiety relate to unique changes in physiology, cognition, and behavior, those changes are correlated, situations that give rise to emotions (...) are consistent, and emotions are complex. To date, there is little experimental evidence regarding whether discrete emotions resolve adaptive problems and do so relatively efficiently. Evidence supporting all criteria is required to claim that discrete emotions are evolved features. (shrink)

When do people say that they are moved, and does this experience constitute a unique emotion? We review theory and empirical research on being moved across psychology and philosophy. We examine feeling labels, elicitors, valence, bodily sensations, and motivations. We find that the English lexeme being moved typically (but not always) refers to a distinct and potent emotion that results in social bonding; often includes tears, piloerection, chills, or a warm feeling in the chest; and is often described as pleasurable, (...) though sometimes as a mixed emotion. While we conclude that it is a distinct emotion, we also recommend studying it in a more comprehensive emotion framework, instead of using the ambiguous vernacular term being moved as a scientific term.

Emotion Review, Volume 14, Issue 1, Page 3-14, January 2022. Advocates for the psychological construction of emotion view themselves as articulating a non-essentialist alternative to basic emotion theory's essentialist notion of affect programs. Psychological constructionists have also argued that holding essentialist assumptions about emotions engenders misconceptions about the psychological constructionist viewpoint. If so, it is important to understand what psychological constructionists mean by “essentialism” and “non-essentialism.” To advance the debate, I take a deeper dive into non-essentialism, comparing the non-essentialist views (...) of the early empiricists with those of the psychological constructionists, focusing on the theories of James Russell and Lisa Barrett. Using Lakatos’ notion of scientific research programs, I also describe how Russell's and Barrett's views have evolved into different and potentially competing research programs under the psychological constructionist banner.

Recent theoretical and philosophical movements within the study of material culture are more carefully attending to the variety of ways in which human artefacts, institutions, and cultural developments extend, shape and alter human cognition over time. Material Engagement Theory in particular has set out to map, explore and understand the relational nature of mind and material world as can be read through cultural artefacts. Within the context of MET, the neurological concept of metaplasticity has been expanded to include the affective (...) domains of technology, materials, and things in the neurological development and architecture of the plastic human mind; a ‘transactional’ relationship between a plastic mind and a plastic material world that are correlated at the ontological level. The challenges of mapping this metaplasticity of mind lie in understanding how the mind and material culture should be understood in relation to the constantly changing lifeworlds of humans over time; the ecological, social, technological and environmental contexts that form the historical specificity of cognitive development. This paper explores how the historical specificity of metaplasticity can be made tangible through the study of material culture, focusing upon the particular activity of oil painting. It will be argued that paintings can provide clues to the historical specificity of the mind that crosses the lifeworld of human action; the technological, phenomenological, philosophical, material, and social conditions underpinning the creation of a painted mark. Drawing from a range of sources that have a root within a Deleuzian process philosophy, the paper builds an account of painting that can be read as expressing the encultured and historical manipulation of paint as an expressive material in itself; an action rendered visible that express the historical emergence of mind.

Signed languages employ finely articulated facial and head displays to express grammatical meanings such as mood and modality, complex propositions, information structure, assertions, content and yes/no questions, imperatives, and miratives. In this paper we examine two facial displays: an upper face display in which the eyebrows are pulled together called brow furrow, and a lower face display in which the corners of the mouth are turned down into a distinctive configuration that resembles a frown or upside-down U-shape. Our analysis employs (...) Cognitive Grammar, specifically the control cycle and its manifestation in effective control and epistemic control. Our claim is that effective and epistemic control are associated with embodied actions. Prototypical physical effective control requires effortful activity and the forceful exertion of energy and is commonly correlated with upper face activity, often called the “face of effort.” The lower face display has been shown to be associated with epistemic indetermination, uncertainty, doubt, obviousness, and skepticism. We demonstrate that the control cycle unifies the diverse grammatical functions expressed by each facial display within a language, and that they express similar functions across a wide range of signed languages.

What’s the difference between those psychological posits that are ‘me” and those that are not? Distinguishing between these psychological kinds is important in many domains, but an account of what the distinction consists in is challenging. I argue for Psychological Constructionism: those psychological posits that correspond to the kinds within folk psychology are personal, and those that don’t, aren’t. I suggest that only constructionism can answer a fundamental challenge in characterizing the personal level – the plurality problem. The things that (...) plausibly qualify as personal are motley. Other attempts at accounting for the personal level either cannot accommodate this plurality, or cannot explain what unifies the personal. Given arguments others have given for a pluralistic conception of folk psychology, constructionism explains and predicts this plurality in a systematic and unified way, thereby solving the plurality problem.

One of the most basic paradoxes of social life is that while we experience ourselves as individuals, we do so only in the context of the pre-existing social environment into which we were born. This environment existed before us and will exist after us . Given this, there are at least two logical ways to study the relationships between the social environment and the individual. On the one hand, you can start at the individual level and analyze how individuals become (...) aggregated to form a social group. But you can also proceed in the opposite direction by asking how the social group creates the individual. Both are valid approaches. The biological sciences .. (shrink)

The interdisciplinary field of emotion studies disregarded historical perspectives on translation and left out a substantial body of scientific research on feelings and emotions that was not published in English. Yet these texts were foundational in forging the scientific concept of emotion in experimental psychology in the 19th century. The current approach to emotion science overlooks that translation issues occurred between three languages, German, French, and English, as physiological psychologists at the time were reading each other in these languages all (...) the while writing about the same topics in their respective language. Historical perspectives are important to clarify the ambiguities of emotion terms and include non-Anglophone frameworks into current transdisciplinary debates. (shrink)

Many nonhuman animals produce facial expressions which sometimes bear clear resemblance to the facial expressions seen in humans. An understanding of this evolutionary continuity between species, and how this relates to social and ecological variables, can help elucidate the meaning, function, and evolution of facial expression. This aim, however, requires researchers to overcome the theoretical and methodological differences in how human and nonhuman facial expressions are approached. Here, we review the literature relating to nonhuman facial expressions and suggest future directions (...) that could facilitate a better understanding of facial expression within an evolutionary context.

In this philosophical paper, we explore computational and biological analogies to address the fine-tuning problem in cosmology. We first clarify what it means for physical constants or initial conditions to be fine-tuned. We review important distinctions such as the dimensionless and dimensional physical constants, and the classification of constants proposed by Lévy-Leblond. Then we explore how two great analogies, computational and biological, can give new insights into our problem. This paper includes a preliminary study to examine the two analogies. Importantly, (...) analogies are both useful and fundamental cognitive tools, but can also be misused or misinterpreted. The idea that our universe might be modelled as a computational entity is analysed, and we discuss the distinction between physical laws and initial conditions using algorithmic information theory. Smolin introduced the theory of "cosmological natural selection" with a biological analogy in mind. We examine an extension of. (shrink)

This article deals with the difficulties of the yet intuitive causal interpretation of the mind–body connection emphasized by metaphysical, theoretical and experimental considerations. It shows that a decisive contribution to determining the nature of this connection can be provided experimentally. This experimental test is designed within the framework of a general systems theory capable of representing the concepts of complementarity and entanglement that are involved in the description of the mind–body connection.

Communication is essential to human society, and assertion is central to communication. This article reviews evidence from life science, cognitive science, and philosophy relevant to understanding how our social practice of assertion is structured and sustained. The principal conclusion supported by this body of evidence is that knowledge is a central norm of assertion—that is, according to the rules of the practice, assertions should express knowledge.

Analysis of sportsmen behavior enabled the authors to conduct simultaneous analysis of emotional expression of people from many distinct countries and cultures. In the study, participants from Nigeria and Poland watched all the goals scored in group matches of the 1998, 2002 and 2006 World Cups and assessed the emotions players expressed after scoring each goal on three scales. Based on the assessment of the participants, emotional expression of football players from 51 countries was analyzed. Basing on “Montesquieu hypothesis”, it (...) was shown that players born in warmer climates express more excitement and happiness after scoring a goal. Further cross-cultural differences were also found. The results are discussed in context of previous cross-cultural studies regarding emotional expression. (shrink)

Recently Geoffrey Miller has suggested that humor evolved through sexual selection as a signal of "creativity," which in turn implies youthfulness, intelligence, and adaptive unpredictability. Drawing upon available empirical studies, I argue that the evidence for a link between humor and creativity is weak and ambiguous. I also find only tenuous support for Miller’s assumption that the attractiveness of the "sense of humor" is to be found in the wittiness of its possessor, since those who use the phrase often seem (...) to associate it with the affects of relatively mirthless "bonding" laughter. Humor, I conclude, may have evolved as an instrument for achieving broad social adhesiveness and for facilitating the individual’s maneuverability within the group, but that it evolved through sexual selection has yet to be convincingly demonstrated.

In the first section of this paper I argue that the main reason why Daniel Dennett’s Intentional Systems Theory (IST) has been perceived as behaviourist or antirealist is its inability to account for the causal efficacy of the mental. The rest of the paper is devoted to the claim that by emending the theory with a phenomenon called ‘empathic resonance’ (ER), it can account for the various explananda in the mental causation debate. Thus, IST + ER is a much more (...) viable option than IST, even though IST + ER assigns a crucial role to the phenomenology of agency, a role that is incompatible with Dennett’s writings on consciousness.

Based on the empirical findings correlating disgust with conservatism, most disgust scholars have fed arguments for its moral unreliability and concluded with moral condemnation of this emotion. In this paper, I will examine common arguments about whether relying on disgust in the moral domain is to be considered good or bad. I will problematize the suggestion that we are justified in firmly believing that disgust is an ethically «dumb» – or an ethically «smart» – emotion. It rather seems that moral (...) disgust can be rational or irrational, pro-social or anti-social, liberal or conservative depending on the eliciting contexts, and that such case-by-case conclusions rely on additional meta-ethical premises.

Paul Ekman is an American psychologist who pioneered the study of facial behaviour. Bringing together disciplinary history, life study, and history of science, this paper focuses on Ekman’s early research during the twenty-year period between 1957 and 1978. I explicate the historical development of Ekman’s semiotic model of facial behaviour, tracing the thread of iconicity through his life and works: from the iconic coding of rapid signs; through the eventual turn from classifying modes of iconic signification using gestalt categories to (...) classifying modes of producing iconic sign-functions using minimal units; to the role and importance of iconicity for the study of the facial expression of emotion, both in terms of the similarities between iconic and analogue signs as well as the differences between facial coding and linguistic signification. In this intellectual genealogy, I argue not only that Ekman relied extensively upon conceptualizations and terminologies from semiotic thought for the creation of the Facial Action Coding System (FACS), but also that the question of iconicity is the pivotal problem across the many discoveries and innovations in what I term ‘Ekmanian faciasemiotics’.

I reject Lindquist et al.'s implicit claim that all emotion theories other than constructionist ones subscribe to a “brain locationist” approach. The neural mechanisms underlying relevance detection, reward, attention, conceptualization, or language use are consistent with many theories of emotion, in particular componential appraisal theories. I also question the authors' claim that the meta-analysis they report provides support for thespecificassumptions of constructionist theories.

The human adventure in education is one of imperfect expression, punctuated by moments of insight. Education cultivates these epiphanies and nurtures their possible continuation. But even without major or minor insights, education cultivates the appreciation of the good, the beautiful, and the true. An experimentalist's sensibility lies amid the humanist's grasp of the myriad ways of trying to understand our existence. To bridge discourse is to appreciate the languages of other cultures, which reveal the nuances of life and experience.

We come prepared to track events and objects, building our knowledge base while foraging for coherence. Classical pragmatism recognizes that the acquisition of knowledge is in part a contact sport (e.g. Peirce, Dewey). One of the aims of neuroscience is to capture human experience. One route to perhaps achieve this may be through the study of the visual system and its expansion in our evolutionary history. Embodied cephalic systems, as Dewey knew well, are tied to self-corrective inquiry. A philosophy of (...) neuroscience needs to capture how such events are tracked, tested through experience, and subsequently modified in the brain to comprise a knowledge base. (shrink)

Humans come prepared to recognize two fundamental features of our surroundings: animate objects and agents. This recognition begins early in ontogeny and pervades our ecological and social space. This cognitive capacity reveals an important adaptation and sets the conditions for pervasive shared experiences. One feature of our species and our evolved cephalic substrates is that we are prepared to recognize self-propelled action in others. Our cultural evolution is knotted to an expanding sense of shared experiences.

We argue that there are three coherent, nontrivial notions of basic-ness: conceptual basic-ness, biological basic-ness, and psychological basic-ness. There is considerable evidence for conceptually basic emotion categories (e.g., “anger,” “fear”). These categories do not designate biologically basic emotions, but some forms of anger, fear, and so on that are biologically basic in a sense we will specify. Finally, two notions of psychological basic-ness are distinguished, and the evidence for them is evaluated. The framework we offer acknowledges the force of some (...) of the objections to basic emotion theory whilst demonstrating that the notion of a basic emotion, once properly reformulated, is still of scientific value.

Lindquist et al. convincingly argue that the brain implements psychological operations that are constitutive of emotion rather than modules subserving discrete emotions.

This paper interrogates Michel Foucault’s claim, that the spread of psychiatric power originated in concerns around the educatability of idiot children in the latter decades of the nineteenth century, before being applied to adult “defectives”. It is argued that Foucault, although partially correct, fails adequately to consider the extent to which the base concept, of “instinct”, was linked in particular ways to female idiot sexuality. The paper challenges Foucault’s view through an analysis of a series of nineteenth century cases involving (...) the rape of female idiots, arguing that their sexuality was understood in terms of a relation to instinct which manifested in terms of an opposition between dangerousness and vulnerability. It then traces that opposition into the Mental Deficiency Act 1913 where, it is argued, it functioned in a collapsed form—now, the vulnerable were dangerous and the dangerous were vulnerable—and in which form it underpinned a psychiatrised regime for the control of mentally defective women through the control of their sexuality.

Contemporary behavioral and brain scientists consider the existence of so-called basic emotions in a similar way to the one described by Erickson for so-called basic tastes. Commenting on this analogy, I argue that similar basic problems are encountered in both perspectives, and I suggest a potential nonbasic solution that is tested in emotion research (i.e., the appraisal model of emotion).

This article provides an analysis of moral emotions from an attributional point of view, guided by the metaphors of man as a naïve scientist (Heider, 1958) and as a moral judge (Weiner, 2006). The theoretical analysis focuses on three concepts: (a) The distinction between the actor and the observer, (b) the functional quality of moral emotions, and (c) the perceived controllability of the causes of events. Moral emotions are identified (admiration, anger, awe, contempt, disgust, elevation, embarrassment, envy, gratitude, guilt, indignation, (...) jealousy, pity, pride, rage, regret, remorse, resentment, respect, schadenfreude, scorn, shame, and sympathy). A classification of these moral emotions is suggested and the empirical evidence briefly summarized. In discussing our results, we identify unresolved issues awaiting further analyses and research.

El artículo propone poner a prueba la idea comúnmente admitida de que en la concepción aristotélica las emociones tienen una función o fin en el ámbito biológico. Me propongo probar que esta concepción sería más propia de otras posturas, como la tomista y la cartesiana, y especialmente de la darwiniana y neo-darwiniana. Tras presentar en la sección 2 el tipo de explicaciones teleológicas que Aristóteles admite y emplea en biología, analizo en la parte 3 la concepción de las emociones de (...) Descartes y en especial de Darwin y muestro que ellas se adaptan bien al modelo explicativo teleológico aristotélico. En la sección 4, ofrezco varios argumentos con apoyo en los textos biológicos de Aristóteles para mostrar que, en cambio, este tipo de explicaciones teleológicas de las emociones no aparecen con claridad en los escritos biológicos del estagirita, toda vez que lo que encontramos allí es, más bien, explicaciones fisiológico materialistas del carácter de los animales. Por último, sugiero una asimetría con el tratamiento de las emociones desde el punto de vista de la racionalidad práctica que desarrollaré en trabajos ulteriores. (shrink)

Previous research suggests that mastering languages with distinct rather than similar rhythmic properties enhances musical rhythmic perception. This study investigates whether learning a second language (L2) enhances the perception of musical rhythmic variation in general, regardless of first and second languages’ rhythmic properties. Additionally, we investigated whether this perceptual enhancement could be alternatively explained by exposure to musical rhythmic complexity, such as the use of compound meter in Turkish music. Finally, it investigates if an enhancement of musical rhythmic perception could (...) be observed among L2 learners whose first language relies heavily on pitch information, as is the case with tonal languages. Therefore, we tested Turkish, Dutch and Mandarin L2 learners of English and Turkish monolinguals on their ability to perceive musical rhythmic variation. Participants’ phonological and working memory capacities, melodic aptitude, years of formal musical training and daily exposure to music were assessed to account for cultural and individual differences which could impact their rhythmic ability. Our results suggest that mastering a second language rather than exposure to musical rhythmic complexity could explain individuals’ enhanced perception of musical rhythmic variation. An even stronger enhancement of musical rhythmic perception was observed for L2 learners whose first and second languages differ regarding their rhythmic properties, as enhanced performance of Mandarin and Turkish in comparison with Dutch L2 learners of English seem to suggest. Our findings provide further support for a cognitive transfer between the language and music domain, which may find its grounds on a common evolutionary basis. (shrink)

An approach to emotion is described in which emotions are defined as states elicited by instrumental reinforcers, that is, by stimuli that are the goals for action. This leads to a theory of the evolutionary adaptive value of emotions, which is that different genes specify different goals in their own self-interest, and any actions can then be learned and performed by instrumental learning to obtain the goals. The brain mechanisms for emotion in brain regions such as the orbitofrontal and anterior (...) cingulate cortex provide a foundation for understanding the neural basis of emotion. Classically conditioned effects may modulate the actions initiated by this system. In addition to this instrumental learning system, some stimuli may elicit responses, for example approach, withdrawal, or fixed action patterns, but intervening states are not required for this type of adaptive response. In addition, a rational thought system involved in multistep planning can allow gene-specified goals to be deferred or avoided in order to achieve longer-term types of goals that may be more advantageous to the individual than to the genes.

The basis of having a direct moral obligation to an entity is that what we do to that entity matters to it. The ability to experience pain is a sufficient condition for a being to be morally considerable. But the ability to feel pain is not a necessary condition for moral considerability. Organisms could have possibly evolved so as to be motivated to flee danger or injury or to eat or drink not by pain, but by “pangs of pleasure” that (...) increase as one fills the relevant need or escapes the harm. In such a world, “mattering” would be positive, not negative, but would still be based in sentience and awareness. In our world, however, the “mattering” necessary to survival is negative—injuries and unfulfilled needs ramify in pain. But physical pain is by no means the only morally relevant mattering—fear, anxiety, loneliness, grief, certainly do not equate to varieties of physical pain, but are surely forms of “mattering.” An adequate morality towards animals would include a full range of possible matterings unique to each kind of animal, what I, following Aristotle, call “telos”. Sometimes not meeting other aspects of animal nature matter more to the animal than does physical pain. “Negative mattering” means all actions or events that harm animals—from frightening an animal to removing its young unnaturally early, to keeping it so it is unable to move or socialize. Physical pain is perhaps the paradigmatic case of “negative mattering”, but only constitutes a small part of what the concept covers. “Positive mattering” would of course encompass all states that are positive for the animal. An adequate ethic for animals takes cognizance of both kinds. The question arises as to how animals value death as compared with pain. Human cognition is such that it can value long-term future goals and endure short-run negative experiences for the sake of achieving them. In the case of animals, however, there is no evidence, either empirical or conceptual, that they have the capability to weigh future benefits or possibilities against current misery. We have no reason to believe that an animal can grasp the notion of extended life, let alone choose to trade current suffering for it. Pain may well be worse for animals than for humans, as they cannot rationalize its acceptance by appeal to future life without pain. How can we know that animals experience all or any of the negative or positive states we have enumerated above? The notion that we needed to be agnostic or downright atheistic about animal mentation, including pain, because we could not verify it through experience, became a mainstay of what I have called “scientific ideology”, the uncriticized dogma taught to young scientists through most of the 20th century despite its patent ignoring of Darwinian phylogenetic continuity. Together with the equally pernicious notion that science is “value-free”, and thus has no truck with ethics, this provided the complete justification for hurting animals in science without providing any pain control. This ideology could only be overthrown by federal law. Ordinary common sense throughout history, in contradistinction to scientific ideology, never denied that animals felt pain. Where, then, does the denial of pain and other forms of mattering come from if it is inimical to common sense? It came from the creation of philosophical systems hostile to common sense and salubrious to a scientific, non-commonsensical world view. Reasons for rejecting this philosophical position are detailed. In the end, then, there are no sound reasons for rejecting knowledge of animal pain and other forms of both negative and positive mattering in animals. Once that hurdle is cleared, science must work assiduously to classify, understand, and mitigate all instances of negative mattering occasioned in animals by human use, as well as to understand and maximize all modes of positive mattering.
