Comparative psychology is a strongly interdisciplinary field that shares many of its experimental methods and observational techniques with ethology and developmental psychology. The great variety of theories that comparative psychology evokes to explain behavior generates a wide array of exciting and potentially fruitful accounts, but is also problematic. It increases the risk of error in the forms of inconsistent background assumptions, conceptual misunderstandings, unfalsifiable hypotheses and incoherent explanations, which in spite of perhaps being minor by themselves will (...) impede scientific progress in the long run. Moreover, similarly to psychology at large, comparative psychology tends to emphasize empirical investigations to the disadvantage of the analysis and development of theories and concepts. Consequently, disagreements that have their roots elsewhere than in methodology and experimental design do not receive sufficient attention. Furthermore, while evidence about biological evolution is notoriously hard to find, the methodology for comparing the capacities of different species is under continuous development. This forces comparative psychology to rely on the adequacy of the theoretical and conceptual framework to a greater extent than normally in the empirical sciences. In view of investigating the background of the problems that contemporary comparative psychology is facing, the present chapter examines central parts of the methodology and explanatory framework of comparative psychology as well as its global objective.

The notions of psychological similarity and probabilistic learning are key posits in cognitive, computational, and developmental psychology and in machine learning. However, their explanatory relationship is rarely made explicit within and across these research fields. This opinionated review critically evaluates how these notions can mutually inform each other within computational cognitive science. Using probabilistic models of concept learning as a case study, I argue that two notions of psychological similarity offer important normative constraints to guide modelers’ interpretations (...) of representational primitives. In particular, the two notions furnish probabilistic models of cognition with meaningful interpretations of what the associated subjective probabilities in the model represent and how they attach to experiences from which the agent learns. Similarity representations thereby provide probabilistic models with cognitive, as opposed to purely mathematical, content. (shrink)

This paper draws on the notion of “objects of research” in psychology as clusters of phenomena (Feest in Philos Sci 84:1165–1176, 2017) to analyze the productive role of folk psychological concepts—and the operational definitions that arise from them—in the development of concepts in scientific psychology. Using the case study of similarity, I discuss the role of the folk psychological concept in the regimentation of different measures of similarity judgments. I propose that by giving rise to operational (...) definitions that lead to experimental dissociation on the one hand, and by providing the concept with unity on the other hand, the folk psychological concept generates a productive tension that facilitates empirical and theoretical development of the scientific concept.

Perceptual similarity is one of the most fiercely debated topics in the philosophy and psychology of perception. The documented history of the issue spans all the way from Plato – who regarded similarity as a key factor for human perceptual experience and cognition – through to contemporary psychologists – who have tried to determine whether, and if so, how similarity relationships can be established between stimuli both within and across the senses. Recent research on cross-sensory associations, (...) otherwise known as crossmodal correspondences – that is, the existence of observable consensual associations, or mappings, between stimuli across different senses – represents an especially interesting field in which to study perceptual similarity. In fact, most accounts of crossmodal association that have been put forward in the literature to date evoke perceptual similarity as a key explanatory factor mediating the underlying association. At the same time, however, these various accounts raise several important theoretical questions concerning the very nature of similarity, with, for example, the sensory, affective, or cognitive underpinnings of similarity judgements remaining unclear. We attempt to shed light on these questions by examining the various accounts of crossmodal associations that have been put forward in the literature. Our suggestion is that perceptual similarity varies from being phenomenologically-based to conceptually-based. In particular, we propose that the nature of the associations underlying similarity judgements – whether these associations are phenomenologically-, structurally-, emotionally-, or conceptually-based – may be represented in a two-dimensional space with associative strength on one axis, and cognitive penetrability on the other.

Previous studies of the lexical psycholinguistic properties in second language production have assessed the degree of an LPP dimension of an L2 corpus by computing the mean ratings of unique content words in the corpus for that dimension, without considering the possibility that learners at different proficiency levels may perceive the degree of that dimension of the same words differently. This study extended a dynamic semantic similarity algorithm to estimate the degree of five different LPP dimensions of several sub-corpora (...) of the Education First-Cambridge Open Language Database representing L2 English learners at different proficiency levels. Our findings provide initial evidence for the validity of the algorithm for assessing the LPPs in L2 production and contribute useful insights into between-proficiency relationships and cross-proficiency differences in the LPPs in L2 production as well as the relationships among different LPP dimensions.

Shepard has argued that a universal law should govern generalization across different domains of perception and cognition, as well as across organisms from different species or even different planets. Starting with some basic assumptions about natural kinds, he derived an exponential decay function as the form of the universal generalization gradient, which accords strikingly well with a wide range of empirical data. However, his original formulation applied only to the ideal case of generalization from a single encountered stimulus to a (...) single novel stimulus, and for stimuli that can be represented as points in a continuous metric psychological space. Here we recast Shepard's theory in a more general Bayesian framework and show how this naturally extends his approach to the more realistic situation of generalizing from multiple consequential stimuli with arbitrary representational structure. Our framework also subsumes a version of Tversky's set-theoretic model of similarity, which is conventionally thought of as the primary alternative to Shepard's continuous metric space model of similarity and generalization. This unification allows us not only to draw deep parallels between the set-theoretic and spatial approaches, but also to significantly advance the explanatory power of set-theoretic models. Key Words: additive clustering; Bayesian inference; categorization; concept learning; contrast model; features; generalization; psychological space; similarity. (shrink)

Modern societies are characterized by group-based hierarchies. Similar to attackers, disadvantaged-group members wish to change the status quo; like defenders, advantaged-group members wish to protect it. However, the psychological arrays that are typical of disadvantaged- and advantaged-group members are opposite to those of attackers and defenders – suggesting that the Attacker-Defender Game does not capture the dynamics between advantaged and disadvantaged groups.

People frequently entertain counterfactual thoughts, or mental simulations about alternative ways the world could have been. But the perceived plausibility of those counterfactual thoughts varies widely. The current article interfaces research in the philosophy and semantics of counterfactual statements with the psychology of mental simulations, and it explores the role of perceived similarity in judgments of counterfactual plausibility. We report results from seven studies (N = 6405) jointly supporting three interconnected claims. First, the perceived plausibility of a counterfactual (...) event is predicted by the perceived similarity between the possible world in which the imagined situation is thought to occur and the actual world. Second, when people attend to differences between imagined possible worlds and the actual world, they think of the imagined possible worlds as less similar to the actual world and tend to judge counterfactuals in such worlds as less plausible. Lastly, when people attend to what is identical between imagined possible worlds and the actual world, they think of the imagined possible worlds as more similar to the actual world and tend to judge counterfactuals in such worlds as more plausible. We discuss these results in light of philosophical, semantic, and psychological theories of counterfactual thinking. (shrink)

Functional neuroimaging is sometimes criticized as showing only where in the brain things happen, not how they happen, and thus being unable to inform us about questions of mental and neural representation. Novel analytical methods increasingly make clear that imaging can give us access to constructs of interest to psychology. In this paper I argue that neuroimaging can give us an important, if limited, window into the large-scale structure of neural representation. I describe Representational Similarity Analysis, increasingly used (...) in neuroimaging studies, and lay out desiderata for representations in general. In that context I discuss what RSA can and cannot tell us about neural representation. I compare RSA with fMRI to a different experimental paradigm which has been embraced as being indicative of representation in psychology, and argue that it compares favorably. (shrink)

The claim that similarity plays a role in representation has been philosophically discredited. Psychologists, however, routinely analyse the success of mental representations for guiding behaviour in terms of a similarity between representation and the world. I provide a foundation for this practice by developing a philosophically responsible account of the relationship between similarity and representation in natural systems. I analyse similarity in terms of the existence of a suitable homomorphism between two structures. The key insight is (...) that by restricting attention to only those homomorphisms induced by causal processes, we can solve two philosophical problems with a single assumption. First, causal structure provides an adequate source for the bias required to ensure the similarity relation is non-trivial; second, it provides an adequate source for the directionality required to move from similarity to representation. I defend this account against objections by Goodman and van Fraassen and demonstrate that it is indeed the account of similarity’s role in representation assumed by psychological practice. (shrink)

When people must either save a greater number of people from a smaller harm or a smaller number from a greater harm, do their choices reflect a reasonable moral outlook? We pursue this question with the help of an experiment. In our experiment, two-fifths of subjects employ a similarity heuristic. When alternatives appear dissimilar in terms of the number saved but similar in terms of the magnitude of harm prevented, this heuristic mandates saving the greater number. In our experiment, (...) this leads to choices that are inconsistent with all standard theories of justice. We argue that this demonstrates the untrustworthiness of distributive judgments in cases that elicit similarity-based choice. (shrink)

One important distinction in psychology is between inferences based on associative memory and inferences based on analysis and rules. Much previous empirical work conceive of associative and analytical processes as two exclusive ways of addressing a judgment task, where only one process is selected and engaged at a time, in an either-or fashion. However, related work indicate that the processes are better understood as being in interplay and simultaneously engaged. Based on computational modeling and brain imaging of spontaneously adopted (...) judgment strategies together with analyses of brain activity elicited in tasks where participants were explicitly instructed to perform similarity-based associative judgments or rule-based judgments (n = 74), we identified brain regions related to the two types of processes. We observed considerable overlap in activity patterns. The precuneus was activated for both types of judgments, and its activity predicted how well a similarity-based model fit the judgments. Activity in the superior frontal gyrus predicted the fit of a rule-based judgment model. The results suggest the precuneus as a key node for similarity-based judgments, engaged both when overt responses are guided by similarity-based and rule-based processes. These results are interpreted such that similarity-based processes are engaged in parallel to rule-based-processes, a finding with direct implications for cognitive theories of judgment. (shrink)

Psychological Sequentialism holds that no causal constraint is necessary for the preservation of what matters in survival; rather, it is sufficient for preservation if two groups of mental states are similar enough and temporally close enough. Suppose one’s body is instantaneously dematerialized and subsequently, by an amazing coincidence, a group of molecules are configured to form a qualitatively identical human body. On this view, these events preserve what matters in survival. Despite its unpopularity, several philosophers have argued for this view. (...) One of the main arguments is that a psychologically sequential person is bound to have the same psychological traits and inclinations, and thus preserves what matters in the original person’s survival. In this paper, I argue that this argument fails to establish that no causal constraint is necessary. I also argue that if sequentialism is true, I should be content with the prospect of my bodily destruction followed by the creation of a series of short-lived beings whose mental states are sequential to mine. I suggest that the implausibility of this implication is sufficient to reject the view. (shrink)

In a famous critique, Goodman dismissed similarity as a slippery and both philosophically and scientifically useless notion. We revisit his critique in the light of important recent work on similarity in psychology and cognitive science. Specifically, we use Tversky’s influential set-theoretic account of similarity as well as Gärdenfors’s more recent resuscitation of the geometrical account to show that, while Goodman’s critique contained valuable insights, it does not warrant a dismissal of similarity.

: Hypotheses are the first step in scientific and clinical enquiry. They guide all of the subsequent steps in an investigation, and influence data collection, analysis, and interpretation. But how do we build scientific and clinical hypotheses? In both research and clinical contexts, a professional’s idiosyncratic way of perceiving reality, her prejudices and biases will influence the process of hypothesis formulation. We compare the process of formulating a scientific hypothesis in the field of neuroscience with the process of building a (...) clinical hypothesis in the systemic therapeutic approach. This comparison is intended to highlight the biases that influence researchers and clinicians when formulating hypotheses. Our aim is to raise awareness of the most common biases, and to point out how the tools developed by clinicians could be useful to researchers, and vice versa.

A comparison between Muḥammad and Siddhārtha’s psychological states is made to identify how they had their mystical experiences and how their presuppositions and personalities shaped their interpretation of these experiences. Muḥammad’s mystical experience appeared to be based on an altered state of consciousness. Siddhārtha’s teachings include that one must not have blind faith and remain open to various truths. These teachings may reflect that he was high in openness to experience, which may have fortified him from becoming delusional. While mystical (...) experiences may have pathological overlaps, they could be categorized in a similar way to psychological states. Yet, mindful presuppositions and personality traits, especially from within openness to experience spectrum, are what make perceptions of these experiences diverse. (shrink)

Counterfactual thinking involves imagining hypothetical alternatives to reality. Philosopher David Lewis argued that people estimate the subjective plausibility that a counterfactual event might have occurred by comparing an imagined possible world in which the counterfactual statement is true against the current, actual world in which the counterfactual statement is false. Accordingly, counterfactuals considered to be true in possible worlds comparatively more similar to ours are judged as more plausible than counterfactuals deemed true in possible worlds comparatively less similar. Although Lewis (...) did not originally develop his notion of comparative similarity to be investigated as a psychological construct, this study builds upon his idea to empirically investigate comparative similarity as a possible psychological strategy for evaluating the perceived plausibility of counterfactual events. More specifically, we evaluate judgments of comparative similarity between episodic memories and episodic counterfactual events as a factor influencing people's judgments of plausibility in counterfactual simulations, and we also compare it against other factors thought to influence judgments of counterfactual plausibility, such as ease of simulation and prior simulation. Our results suggest that the greater the perceived similarity between the original memory and the episodic counterfactual event, the greater the perceived plausibility that the counterfactual event might have occurred. While similarity between actual and counterfactual events, ease of imagining, and prior simulation of the counterfactual event were all significantly related to counterfactual plausibility, comparative similarity best captured the variance in ratings of counterfactual plausibility. Implications for existing theories on the determinants of counterfactual plausibility are discussed. (shrink)

The evolutionary advantage of psychological phenomena can be gleaned by comparing them with physical traits that have proven adaptive in other organisms. The present article provides a novel evolutionary explanation of suicide in humans by comparing it with aposematism in insects. Aposematic insects are brightly colored, making them conspicuous to predators. However, such insects are equipped with toxins that cause a noxious reaction when eaten. Thus, the death of a few insects conditions predators to avoid other insects of similar coloration. (...) Analogously, human suicides may increase the credibility of future suicide threats and attempts from others, conveying an evolutionary advantage to the phenotypic expression of suicidal behavior in low-fitness contexts.

Concepts allow us to treat different objects equivalently according to shared attributes, and hence to communicate about, draw inferences from, reason with, and explain these objects. Understanding how concepts are formed and used is thus essential to understanding and applying these basic processes, and the topic of similarity-based classification is central to psychology, artificial intelligence, statistics, and philosophy. This book brings together leading researchers, reflecting the key topics and important developments in the field and provides a uniquely interdisciplinary (...) overview of the subject. (shrink)

Psychology, often defined as the science of human behavior, has so far had little to say about the environmental destruction which is currently occurring as the result of human behavior. I consider the reasons why it has not and suggest that the ideological preconceptions that underpin the discipline are similar to those of the technological-economic system that is largely responsible for degradation ofthe environment. Psychology, by normalizing the behavioral, life-style, and personality configurations associated with environmental destruction, and lacking (...) a historical perspective on changes in consciousness and technology, is unable to contribute effectively to the ecological debate. I conclude that the discipline needs to locate itself historically and ideologically before it can offer an adequate analysis of environmental destruction. (shrink)

Like philosophy itself, Dune explores everything from politics to art to life to reality, but above all, the novels ponder the mysteries of mind. Voyaging through psychic expanses, Frank Herbert hits upon some of the same insights discovered by indigenous people from the Americas. Many of these ideas are repeated in mainstream American and European philosophical traditions like pragmatism and existential phenomenology. These outlooks share a regard for mind as ecological, which is more or less to say that minds extend (...) beyond the brain into the rest of the body and the surrounding environment. -/- The cross-cultural strands in Dune tie closely to Herbert’s life and interests. An outdoorsman born in the Pacific West, he had an abiding bond with a friend from the Quileute tribe, Howie Hansen. Herbert advocated for aboriginal rights and crafted well-intentioned if slightly stereotypical tales about indigenous characters, partly based on his visits with Northwest tribes. Carl Jung (1875-1961), whose idea of collective consciousness echoes aboriginal views, was among Herbert’s European influences. So was existential phenomenology, especially as developed by Martin Heidegger (1889-1976). The names of characters in one of Herbert’s novels—The Santaroga Barrier—in fact coincide with terms that Heidegger used to articulate how emotionally colored coping with our environment defines our existence. Many indigenous philosophers have treated phenomenology and its American cousin pragmatism in approving ways. Indeed, the ideas of North America’s first inhabitants seem to have been absorbed by pragmatists and even earlier by transcendentalists like Ralph Waldo Emerson (1803-1882) and Henry David Thoreau (1817-1862). -/- These different philosophies all advance a place-based psychology. Anne Waters, herself of mixed tribal heritage, generalizes the mindset of her people this way: “American Indian consciousness, and hence American Indian identity is … interdependent with our land base.” Lee Hester, a Choctaw thinker, adds that practices—not mere beliefs—are most important for native thought. American transcendentalists and pragmatists, as well as European phenomenologists, similarly see hands-on practices and environmental interactions as the core of experience. Extending this a little, they sometimes suggest experience isn’t individual but instead cultural. “Culture” is here understood as interactions within communities that define our worlds and experiences, as when we talk about the “French experience,” “culture” or “world,” or the “experience of parenthood.” This theme also shows up in indigenous thought. -/- Exploring the Dune universe, we find everything from land-based concepts of personal identity, to the idea of sharpening the mind through hands-on training, to collective notions of experience in cooperative tribes or through the genetic memory of central characters. The stories explore fate versus free will in cosmic contexts, introducing views from indigenous thought and the pragmatic philosophy of William James (1842-1910). Different forms of spiritualism mingle to shape minds and cultural mixtures around the globe, and the same occurs in the Dune series. The customs and personalities of characters fuse elements from Buddhism, Christianity, Hinduism, Judaism, Taoism, and especially Islam. The series not only highlights that religion shapes psychology, but also that faith connects to place, especially paralleling Judeo-Christian-Islamic desert faiths. In capturing these points, the Dune novels show that “our values, our lifestyles and even the ways we think and feel have been strongly influenced by our locations in history and geography. The study of the human mind is fundamentally the study of place.”. (shrink)

Psychology has a long past, yet its real history is short. For thousands of years it has existed and has been growing older; but in the earlier part of this period it cannot boast of any continuous progress toward a riper and richer development. In the fourth century before our era that giant thinker, Aristotle, built it up into an edifice comparing very favorably with any other science of that time. But this edifice stood without undergoing any noteworthy changes (...) or extensions, well into the eighteenth or even the nineteenth century. Only in recent times do we find an advance, at first slow but later increasing in rapidity, in the development of psychology. The general causes which checked the progress of this science and thus made it fall behind the others can readily be stated:— "The boundaries of the Soul you cannot find, though you pace off all its streets, so deep a foundation has it," runs a sentence of Heraclitus, and it hits the truth more fully than its author could ever have expected. The structures and functions of our mental life present the greatest difficulties to scientific investigation, greater even than those presented by the phenomena, in many respects{4} similar, of the bodily life of the higher organisms. These structures and processes change so unceasingly, are so fleeting, so enormously complex, and dependent on so many factors hidden yet undoubtedly influential, that it is difficult even to seize upon them and describe their true substance, still more difficult to gain an insight into their causal connections and to understand their significance. We are just now beginning to recognize the full force of these difficulties. (shrink)

Psychological consequences of money and money attitudes in dictator game According to the research conducted by Vohs, Mead, and Goode, reminders of money cause people to behave self-sufficiently, and especially to reveal a reduced tendency to charitable behaviour. In this study, we wanted to establish if this tendency would be present in the dictator game, and if so, whether money activation would just change behaviour, or whether it would also change people's evaluation of their own decisions. We assumed that people (...) who revealed symbolic and instrumental money attitudes would react differently to money activation. As expected, money priming caused smaller money transfers compared to the control condition, and this effect was significant among those with symbolic attitudes toward money. Moreover, participants who transferred at least half of the sum after money activation declared stronger negative emotions and lower satisfaction with the decision than those who made similar transfers in the control condition.

Evolutionary psychologists claim that the mind contains “hundreds or thousands” of “genetically specified” modules, which are evolutionary adaptations for their cognitive functions. We argue that, while the adult human mind/brain typically contains a degree of modularization, its “modules” are neither genetically specified nor evolutionary adaptations. Rather, they result from the brain’s developmental plasticity, which allows environmental task demands a large role in shaping the brain’s information-processing structures. The brain’s developmental plasticity is our fundamental psychological adaptation, and the “modules” that result (...) from it are adaptive responses to local conditions, not past evolutionary environments. If different individuals share common environ- ments, however, they may develop similar “modules,” and this process can mimic the development of genetically specified modules in the evolutionary psychologist’s sense.

Drawing on early work on ethical leadership, we argue that when leaders engage in leader moral hypocrisy (i.e., ethical promotion without ethical demonstration), followers can experience psychological reactance—a negative response to a perceived restriction of freedom—which can have negative downstream consequences. In a survey of employee–manager dyads (study 1), we demonstrate that leader moral hypocrisy is positively associated with follower psychological reactance, which increases follower deviance. In two subsequent laboratory experiments, we find similar patterns of results (study 2) and explore (...) potential alternative mechanisms (study 3). We demonstrate in a final experiment with working adults that the relationship between leader moral hypocrisy and psychological reactance is partly explained by increased perceptions of a leader’s use of power (study 4). We discuss the implications of our findings and advocate for further understanding of the risks associated with psychological reactance in response to leaders and other workplace situations.

Empathy is an important human ability associated with successful social interaction. It is currently unclear how to optimally measure individual differences in empathic processing. Although the Big Five model of personality is an effective model to explain individual differences in human experience and behavior, its relation to measures of empathy is currently not well understood. Therefore, the present study was designed to investigate the relationship between the Big Five personality concept and two commonly used measures for empathy (Empathy Quotient (EQ), (...) Interpersonal Reactivity Index (IRI)) in four samples from China, Germany, Spain and the United States of America. This approach was designed to advance the way the Big Five personality model can be used to measure empathy. We found evidence of medium effect sizes for associations between personality and empathy, with agreeableness and conscientiousness as the most important predictors of affective and cognitive empathy (measured by the respective IRI subscales) as well as a for a one-dimensional empathy score (measured by the EQ). Empathy in a fictional context was most closely related to openness to experience while personal distress was first of all related to neuroticism. In terms of culture, we did not observe any distinct pattern concerning cultural differences. These results support the cross-cultural applicability of the Empathy Quotient and the Interpersonal Reactivity Index and indicate structurally similar associations between personality and empathy across cultures.

Humanists argue for assigning the highest moral status to all humans over any non-humans directly or indirectly on the basis of uniquely superior human cognitive abilities. They may also claim that humanism is the strongest position from which to combat racism, sexism, and other forms of within-species discrimination. I argue that changing conceptual foundations in comparative research and discoveries of advanced cognition in many non-human species reveal humanism’s psychological speciesism and its similarity with common justifications of within-species discrimination.

Leveraging a massive dataset of over 400 million potential matches between single heterosexuals on a leading mobile dating application we were able to identify numerous characteristics of effective matching. Effective matching is defined as the exchange of contact information with the intent to meet in person. The characteristics of effective match include alignment of psychological traits (i.e. extroversion), physical traits (i.e. height), personal choices (i.e., the relationship type they desired), and shared experiences. For nearly all characteristics, the more similar the (...) individuals were the higher the likelihood of them finding each other desirable and opting to meet in person. The only exception was introversion, where introverts rarely had an effective match with other introverts. Additionally, we investigated the preliminary stages of the choice process. We looked at the consistency between the choice of men/women, the time it took users to make these binary choices and the tendency of yes/no decisions. We used a biologically-inspired choice model to estimate the time allotted to a decision and could predict the decision and response time with nearly 60% accuracy. Given that people make their initial selection within no more than 11 seconds and ultimately converge to a partner who shares numerous attributes with them, we suggest that users are less selective in their early preferences and gradually converge to clusters with high degree of similarity in characteristics during their conversation.

Convolutional neural networks (CNNs) are increasingly widely used in psychology and neuroscience to predict how human minds and brains respond to visual images. Typically, CNNs represent these images using thousands of features that are learned through extensive training on image datasets. This raises a question: How many of these features are really needed to model human behavior? Here, we attempt to estimate the number of dimensions in CNN representations that are required to capture human psychological representations in two ways: (...) (1) directly, using human similarity judgments and (2) indirectly, in the context of categorization. In both cases, we find that low-dimensional projections of CNN representations are sufficient to predict human behavior. We show that these low-dimensional representations can be easily interpreted, providing further insight into how people represent visual information. A series of control studies indicate that these findings are not due to the size of the dataset we used and may be due to a high level of redundancy in the features appearing in CNN representations.

We report the results of a cross-cultural investigation of person-body reasoning in the United Kingdom and northern Brazilian Amazon (Marajó Island). The study provides evidence that directly bears upon divergent theoretical claims in cognitive psychology and anthropology, respectively, on the cognitive origins and cross-cultural incidence of mind-body dualism. In a novel reasoning task, we found that participants across the two sample populations parsed a wide range of capacities similarly in terms of the capacities’ perceived anchoring to bodily function. Patterns (...) of reasoning concerning the respective roles of physical and biological properties in sustaining various capacities did vary between sample populations, however. Further, the data challenge prior ad-hoc categorizations in the empirical literature on the developmental origins of and cognitive constraints on psycho-physical reasoning (e.g., in afterlife concepts). We suggest cross-culturally validated categories of “Body Dependent” and “Body Independent” items for future developmental and cross-cultural research in this emerging area. (shrink)

Autonomous sensory meridian response is a complex sensory-emotional experience characterized by pleasant tingling sensations initiating at the scalp. ASMR is triggered in some people by stimuli including whispering, personal attention, and crisp sounds. Since its inception, ASMR has been likened to synesthesia, but convincing empirical data directly linking ASMR with synesthesia is lacking. In this study, we examined whether the prevalence of synesthesia is indeed significantly higher in ASMR-responders than non-responders. A sample of working adults and students were surveyed about (...) their experience with ASMR and common types of synesthesia. The proportion of synesthetes who were classified as ASMR-responders was 52%, whereas 22% of ASMR-responders were also synesthetes. These results suggest that: over half of those identifying as synesthetes also experience ASMR, and that synesthesia is up to four times as common among ASMR-responders as among non-responders. Findings also suggest a prevalence rate for ASMR of approximately 20%. Overall, the co-occurrence of ASMR and synesthesia lends empirical support to the idea that ASMR may be driven by synesthetic mechanisms, but future research would benefit from examining how ASMR and synesthesia are different, as well as similar.

Mechanistic explanation has an impressive track record of advancing our understanding of complex, hierarchically organized physical systems, particularly biological and neural systems. But not every complex system can be understood mechanistically. Psychological capacities are often understood by providing cognitive models of the systems that underlie them. I argue that these models, while superficially similar to mechanistic models, in fact have a substantially more complex relation to the real underlying system. They are typically constructed using a range of techniques for abstracting (...) the functional properties of the system, which may not coincide with its mechanistic organization. I describe these techniques and show that despite being non-mechanistic, these cognitive models can satisfy the normative constraints on good explanations. (shrink)

It is proposed to conceive of representation as an emergent phenomenon that is supervenient on patterns of activity of coarsely tuned and highly redundant feature detectors. The computational underpinnings of the outlined concept of representation are (1) the properties of collections of overlapping graded receptive fields, as in the biological perceptual systems that exhibit hyperacuity-level performance, and (2) the sufficiency of a set of proximal distances between stimulus representations for the recovery of the corresponding distal contrasts between stimuli, as in (...) multidimensional scaling. The present preliminary study appears to indicate that this concept of representation is computationally viable, and is compatible with psychological and neurobiological data. (shrink)

A summary of recent experimental results shows that entanglement can be generated more easily than before, and that there are improved chances for its persistence. An eminent finding of Generalised Quantum Theory is the insight that the notion of entanglement can be extended, such that, e.g., psychological or psychophysical problem areas can be included, too. First, a general condition for entanglement to occur is given by the term ‘common prearranged context’. A formalised treatment requires a quantitative definition of the (...) class='Hi'>similarity or dissimilarity between two complex structures which takes their internal structures into account. After some specific remarks on distance, metrics, and semi-metrics in mathematics, a procedure is described for setting up a similarity function with the required properties. This procedure is in analogy with the two-step character of measurement and with the well-known properties of perspective notions. A general methodology can be derived for handling perspective notions. Finally, these concepts supply heuristic clues towards a formalised treatment of the notions of ‘meaning’ and ‘interpretation’.

Psychological ownership may be judged differently or similarly for self and others. Potential differences in how ownership is evaluated by actors and observers raise important questions about the concept of ownership (what is Mine, Ours, and Theirs) and how to resolve conflicting perceptions.

When Thomas Jefferson placed 'the pursuit of happiness' along with life and liberty in The Declaration of Independence he was most likely referring to Aristotle's concept of happiness, or eudaimonia. Eudaimonia is not about good feelings but rather the fulfilment of human potentials. Fulfilment is made possible by virtue; the moderation of desire and emotion by reason. The Psychology of Happiness was the first book to bring together psychological, philosophical, and physiological theory and research in support of Aristotle's view. (...) It examines the similarity between Aristotle's concept of virtue and modern cognitive theories of emotion. It discusses the discovery of human potentials, the development of virtue and its neurological basis, the mistaken idea that fulfilment is selfish, and several other issues related to the pursuit of a good human life.

This chapter examines the similarities and differences between physical, psychological and virtual realities, and challenges some conventional, implicitly dualist assumptions about how these relate to each other. Virtual realities are not easily understood in either dualist or materialist reductive terms, as they exemplify the reflexive nature of perception. The chapter summarises some of the evidence for this “reflexive model”—and examines some of its consequences for the “hard” problem of consciousness. The chapter then goes on to consider how these realities might (...) relate to some grounding reality or thing-itself, and considers some of the personal and social consequences of becoming increasingly immersed in virtual realities. Although this chapter was published in 1998 and develops work published in 1990, it presents a form of “radical externalism” that anticipates many themes in current (2006) internalism versus externalism debates about the nature of mind. It is also relevant to an understanding of virtual reality “presence.”. (shrink)

Recent philosophical discussions of intersubjectivity generally start by stating or assuming that our ability to understand and interact with others is enabled by a ‘folk psychology’ or ‘theory of mind’. Folk psychology is characterized as the ability to attribute intentional states, such as beliefs and desires, to others, in order to predict and explain their behaviour. Many authors claim that this ability is not merely one amongst many constituents of interpersonal understanding but an underlying core that enables social (...) life. For example, Churchland states that folk psychology ‘embodies our baseline understanding’ of others. Currie and Sterelny similarly assert that ‘our basic grip on the social world depends on our being able to see our fellows as motivated by beliefs and desires we sometimes share and sometimes do not’. And, as Frith and Happé put it, ‘this ability appears to be a prerequisite for normal social interaction: in everyday life we make sense of each other’s behaviour by appeal to a belief-desire psychology’.

Introduction Comparative psychology can generally be defined as the branch of psychology that studies the similarities and differences in the behavior of organisms. Formal definitions found in textbooks and encyclopedias disagree whether comparative psychologists restrict their work to the study of animals or include the study of human behavior. This paper offers an opinion on the major problem facing comparative psychology today – where we will find the next generation of comparative psychology students. Something must be (...) done before we lose access to an entire generation of psychology undergraduates. It is not enough to say that comparative psychology is being “absorbed” in other academic units such as “integrative biology”, “integrative study of animal behavior”, “evolutionary psychology”, “comparative cognition”, or “animal cognition.” Indeed, many of these topics are not primarily studied in psychology departments, wherein comparative psychology students have traditionally received joint training in the principles of behavior and comparative analysis, as applied to both humans and other animals. Consider, for example, the difference between comparative psychology and comparative cognition. Comparative cognition includes features of comparative psychology, but they are not identical. Comparative cognition represents a very specific theoretical position whose validity is based on certain suppositions such as the belief (by definition) that the internal cogni... (shrink)

This open access book discusses a variety of important but unprecedented ways in which psychology can be useful to philosophy. The early chapters illustrate this theme via comparisons between Chinese and Western philosophy. It is argued that the Chinese notion of a heart-mind is superior to the Western concept of mind, but then, more even-handedly, the relative strengths and weaknesses of Chinese and Western thought overall are critically examined. In later chapters, the philosophical uses of psychology are treated (...) more specifically in relation to major issues in Western philosophy. Michael Slote shows that empathy and emotion play a role in speech acts that speech act theory has totally ignored. Similarly, he treats the age-old question of whether justice pays using psychological material that has not previously been recognized. Finally, the implications of psychological egoism are discussed in terms of some new psychological and, indeed, human distinctions. Human life is pervaded by instincts and aspirations that are neither egoistic nor altruistic, and recognizing that fact can help put egoism in its place. It is less of a challenge to morality than we have realized. (shrink)

Moral Psychology: Historical and Contemporary Readings is a much-needed collection of essays on issues of moral psychology. The aim of the book is to present the reader with a comprehensive view of both the history and foundations of moral psychology as well as the discipline's position in academia and its relationship with other disciplines, such as psychology, neuroscience, and evolutionary biology, all of which involve empirical investigation of human capabilities and behavior. This collection is well organized (...) into five distinct parts. Each part has a helpful editorial introduction that not only summarizes the main themes of the debate assigned to that part, but also provides brief summaries of each of the subsequent essays in that section. The selected papers are presented in chronological order, thus illustrating the development of the debate. First, an historical piece of philosophy is presented to demonstrate the original questions of the section's theme. The historical pieces are followed by more-recent articles or selections written by scientists concerning similar topics. Finally, each part concludes with articles written by contemporary moral psychologists. These final articles often make mention of the historical texts or the scientific articles preceding those papers. This dialectic style of presentation successfully gives the reader the context and progression of the debate while still highlighting the "live" questions that are, in a sense, left as an exercise for the reader as well as future academics.

ABSTRACT:In this article, we describe evolutionary psychology and its potential contribution to business ethics research. After summarizing evolutionary theory and natural selection, we specifically address the use of evolutionary concepts in psychology in order to offer alternative explanations of behavior relevant to business ethics, such as social exchange, cooperation, altruism, and reciprocity. Our position is that individuals, groups, and organizations all are affected by similar natural, evolutionary processes, such that evolutionary psychology is applicable at multiple levels of (...) analysis (e.g., individual and group). We introduce a variety of experiments and instruments employed by evolutionary psychologists to illustrate how ethics-relevant cultural norms and practices evolve and are regulated, and to raise the prospect that these experiments and instruments can be useful in future business ethics research.

A central controversy in cognitive science concerns the roles of rules versus similarity. To gain some leverage on this problem, we propose that rule‐ versus similarity‐based processes can be characterized as extremes in a multidimensional space that is composed of at least two dimensions: the number of features (Pothos, 2005) and the physical presence of features. The transition of similarity‐ to rule‐based processing is conceptualized as a transition in this space. To illustrate this, we show how a (...) neural network model uses input features (and in this sense produces similarity‐based responses) when it has a low learning rate or in the early phases of training, but it switches to using self‐generated, more abstract features (and in this sense produces rule‐based responses) when it has a higher learning rate or is in the later phases of training. Relations with categorization and the psychology of learning are pointed out. (shrink)

Exploration of the meanings, dimensions, levels of the umbrella-notion of wisdom. I added a discussion between the academics of the notion and research into it (on Wisdom list [email protected] ) as second appendix. I added on 7/09/2017 a new appendix http://www.drrogerwalsh.com/wp-content/uploads/2009/07/What-is-Wisdom-Cross-Cultural-Cross-Disciplin ary-Syntheses-Roger-Walsh-2015-Review-of-General-Psychology.pdf . -/- Most people involved in this discourse will be aware of the meaning of the word philosophy. The love part might be familiar to many of the human beings, although each individual will probably have his/her own superficial (...) notion of this idea. It is the second part of the word that will baffle anyone who reflects at all. The notion of wisdom is another umbrella-word, like mind, consciousness, reality, the world, etc. Notions that cover a whole range of ideas and concepts, but that are frequently employed as if it has one specific, precisely defined meaning and usage. When we are informed about the three, four or five features, aspects or characteristics of the word wisdom, we are actually presented with some form of conceptual analysis of possible meanings of the word wisdom. In the following 7 dimensions (characteristics?) of the notion or idea of wisdom are proposed. This is like a conceptual analysis of the word wisdom. Brown and Greene outline their efforts to developing and testing a reliable ‘Wisdom Development Scale’. Their study provides evidence to support the theory that wisdom is a multidimensional construct with the following 7 dimensions: (1) Self-Knowledge (2) Emotional Management (3) Altruism (4) Inspirational Engagement (5) Judgment (6) Life Knowledge (7) Life Skills Jeste suggests that: Most of us agree that wisdom is a complex trait. It’s not just one thing – it’s not like ‘optimism,’ which is a single specific trait. Wisdom is far more complex, comprised of different components. He says: He found six such dimensions or components. Social decision-making. ‘Emotional Regulation’ – control over one’s emotions. ,The third one is ‘Prosocial Behaviours’ – things that we do for others ,Then comes ‘Insight’ – knowing yourself. It includes self-reflection,The fifth is ‘Acceptance of uncertainty’, which also means ‘acceptance of diversity of views.’ ,The last component in that list was still being ‘Decisive’, in that you accept uncertainty, you accept diversity of views, and yet you cannot sit on the fence all the time. You cannot be ambivalent all the time. You have to make a decision. We found that those six were still the most common components, but there were three others that some people have proposed as components of wisdom. Those three are ‘Spirituality’, ‘Sense of Humor’ and ‘Openness to new experience.’ -/- . (shrink)

According to Hugo Münsterberg, the direct application of experimental psychology to the practical problems of education, law, industry, and art belonged by definition to the domain of psychotechnics. Whether in the form of pedagogical prescription, interrogation technique, hiring practice, or aesthetic principle, the psychotechnical method implied bringing the psychological laboratory to bear on everyday life. There were, however, significant pitfalls to leaving behind the putative purity of the early psychological laboratory in pursuit of technological utility. In the Vocation Bureau, (...) for example, psychological instruments were often deemed too intimidating for a public unfamiliar with the inner workings of experimental science. Similarly, when psychotechnical means were employed by big business in screening job candidates, ethical red flags were raised about this new alliance between science and capital. This tension was particularly evident in Münsterberg's collaboration with the Paramount Pictures Corporation in 1916. In translating psychological tests into short experimental films, Münsterberg not only envisioned a new mass medium for the dissemination of psychotechnics, but a means by which to initiate the masses into the culture of experimental psychology.

Specifying accurate informative prior distributions is a question of carefully selecting studies that comprise the body of comparable background knowledge. Psychological research, however, consists of studies that are being conducted under different circumstances, with different samples and varying instruments. Thus, results of previous studies are heterogeneous, and not all available results can and should contribute equally to an informative prior distribution. This implies a necessary weighting of background information based on the similarity of the previous studies to the focal (...) study at hand. Current approaches to account for heterogeneity by weighting informative prior distributions, such as the power prior and the meta-analytic predictive prior are either not easily accessible or incomplete. To complicate matters further, in the context of Bayesian multiple regression models there are no methods available for quantifying the similarity of a given body of background knowledge to the focal study at hand. Consequently, the purpose of this study is threefold. We first present a novel method to combine the aforementioned sources of heterogeneity in the similarity measure ω. This method is based on a combination of a propensity-score approach to assess the similarity of samples with random- and mixed-effects meta-analytic models to quantify the heterogeneity in outcomes and study characteristics. Second, we show how to use the similarity measure ωas a weight for informative prior distributions for the substantial parameters in Bayesian multiple regression models. Third, we investigate the performance and the behavior of the similarity-weighted informative prior distribution in a comprehensive simulation study, where it is compared to the normalized power prior and the meta-analytic predictive prior. The similarity measure ω and the similarity-weighted informative prior distribution as the primary results of this study provide applied researchers with means to specify accurate informative prior distributions.
