This article investigates how age categorisation and prejudicial use of age are mobilised in talk by job applicants during job interviews and how recruiters affiliate with these. The institutional goal of recruitment is to ensure an unbiased process and evaluation, nevertheless, ageism against older workers emerges as unchallenged and culturally acceptable in authentic job interviews. In line with the discursive psychology (DP) approach, the analysis focuses on -isms as discursively constructed and categories as resources to accomplish social actions. A (...) case study is conducted based on video recordings of 24 real job interviews held at an Italian staffing agency and analysed through membership categorisation and conversation analysis. The analysis provides evidence of how job applicants resort to age co-membership with recruiters to achieve affiliation – or remedy misalignment – by complaining about older workers. The study contributes to DP’s re-specification of prejudices as interactional practices and links microanalysis to macro phenomena, such as ageism, through categorisation practices. (shrink)

First published in 1984, this is a study of categorization practices: how people categorize each other and their actions; how they describe, infer, and judge. The book presents a sociological analysis and description of practical activities and makes a cogent contribution to the study of how the moral order actually works in practical communicative contexts. Among the issues dealt with are: collectivity categorizations, the organization of lists and descriptions, moral attribution and inferences, and the relationship between standards of morality (...) and standards of rationality.

Categorisation models of metaphor interpretation are based on the premiss that categorisation statements and comparison statements are fundamentally different types of assertion. Against this assumption, we argue that the difference is merely a quantitative one: ‘x is a y’ unilaterally entails ‘x is like a y’, and therefore the latter is merely weaker than the former. Moreover, if ‘x is like a y’ licenses the inference that x is not a y, then that inference is a scalar implicature. We defend (...) these claims partly on theoretical grounds and partly on the basis of experimental evidence. A suite of experiments indicates both that ‘x is a y’ unilaterally entails that x is like a y, and that in several respects the non-y inference behaves exactly as one should expect from a scalar implicature. We discuss the implications of our view of categorisation and comparison statements for categorisation models of metaphor interpretation. (shrink)

The article explores digital literacy practices in children’s everyday lives at Norwegian preschools and some of the ways in which young children appropriate basic digital literacy skills through guided participation in situated activities. Building on an ethnomethodological perspective, the analyses are based on 70 hours of video recordings documenting the activities in which 45 children, aged 5-6, and eight preschool teachers participated. Through the detailed analysis of two categorization activities – identifying geometrical shapes and identifying feelings/thoughts –the use of (...) digital tools in the social organization of the activities are examined. The article finds that children’s digital literacy activities encompass visual, verbal, audio and embodied competencies that are made relevant, and thus accessible for learning, in interaction between the children and between the adults and children in the form of norms and guidelines for what constitutes correct categorizations (geometrical shapes and green and red feelings) in the situated activities, and that are appropriated and actualized by the children in interaction with their peers. The findings also show how the categorization practices in preschools deal with symbols and labels in ways that create and sustain socially organized ways of knowing, seeing and acting upon the world. Digital media are embedded in routines, procedures and socialites that are part of these categorization practices; they are part of how children are instructed to experience, interpret, understand and act in the world. Moreover, the different technologies created different conditions for the children’s participation. It was found that peer interaction was part of the digital literacy activities that involved such mobile technologies as smartphones and tablets, while when using non-mobile technologies, e.g. smartboards, the activities were structured more as ‘classic’ classroom activities, primarily guided by the teacher and the didactic material presented through the smartboard.

Many philosophers, and particularly those of a Kantian stripe, have suspected that claims about the ways the world and its Joints are (in contrast to claims about the joints in our models of the world and the way they are) make little sense. Recently, similar views have gained prominence in the philosophy of science and in cognitive psychology. The demise of the strong distinction between theoretical and observational terms over the past two decades is just one, among many, developments (...) in the philosophy of science which is of a piece with such suspicions. Meanwhile, a great deal of recent theoretical work on the psychology of categorization also affirms the fundamentality of our cognitive constructs in structuring human experience. (shrink)

In this paper I discuss the circumstances in which it would be right to revise a common-sense psychological categorisation -- such as the common-sense categorisation of emotions -- in the light of the results of empirical investigation. I argue that an answer to that question, familiar from eliminitivist arguments, should be rejected, and suggest that the issue turns on the ontological commitments of the explanations that common-sense psychological states enter into.

In this chapter I discuss the role of mind perception in the categorization of individuals as moral agents and moral patients. Moral agents are defined as individuals that can commit morally wrong actions and deserve to be held accountable for those actions; moral patients are defined as individuals that can be morally wronged and whose interests are worthy of moral consideration. It is generally agreed that the attribution of moral agency and moral patiency is linked to the attribution of (...) mental capacities and traits. The chapter surveys a variety of models of mind perception, some of which focus on the representation of mental capacities, some of which focus on the representation of mental traits. The dominant model of mind perception in moral psychology is the experience-agency model (Gray et al., 2007), which divides the space of mindedness into experiential capacities like sentience and self-awareness, and agentic capacities like deliberative reasoning and self-control. Reviewing the empirical literature on moral categorization, I argue that neither the experience-agency model nor any of the major alternatives to it (i.e., the warmth-competence model, the agency-communion model, and the human nature–human uniqueness model), captures the full panoply of mental features to which everyday attributions of moral agency and moral patiency are sensitive.

In this chapter, I critically examine two of the main approaches to colour categorization in cognitive science: the perceptual salience theory and linguistic relativism. I then turn to reviewing several decades of psychological research on colour categorical perception (CP). A careful assessment of relevant findings suggests that most of the experimental effects that have been understood in terms of CP actually fall on the cognition side of the perception-cognition divide: they are effects of colour language, for example, on memory (...) or decision-making.

The study of concepts lies at the intersection of various disciplines, both analytic and empiric. The rising cognitive sciences, for instance, are interested in concepts insofar as they are used in an explanation of such diverse epistemic phenomena like categorization, inference, memory, learning, and decision-making. In philosophy, the challenge imposed by conceptualization consists, among other things, in accommodating reverse intuitions about concepts like shareability, mind-dependency, mediation between reference, knowledge and reality, etc. While researchers have collaborated more and more to (...) contribute to a unified understanding of concepts and categorization, the joint venture unfortunately suffers (so far) from the fact that it is generally left unclear how exactly the different approaches undertaken in the participating sciences relate to each other. What do psychologists and philosophers mean by the notion of a concept? Is there a core-theory of concepts and categorization underlying analytical and empirical studies? The present collection of essays addresses these and related questions and tries to answer them from both a systematic and a historical perspective. (shrink)

I discuss Edouard Machery’s claim that philosophers and psychologists when using the term ‘concept’ are really theorizing about different things. This view is not new, but it has never been developed or defended in detail. Once spelled out, we can see that Machery is right that the psychological literature uses a different notion of concept. However, Machery fails to acknowledge that the two notions are not only compatible but complementary. This fits more with the traditional view according to which philosophers (...) and psychologists are merely interested in different aspects of the same kind. The main aim of this paper is then to show how precisely the two notions of ‘concept’ relate. Distinguishing them resolves the long-standing debate on whether concepts can be prototypes and allows me to formulate success conditions of a theory of categorization that are independent of the success conditions of a theory of concepts.

Philosophers and psychologists widely hold that artifact categories – just like biological categories – are individuated by their function. But recent empirical findings in psychology question this assumption. My proposal is to suggest a way of squaring these findings with the central role function should play in individuating artifact categories. But in order to do so, we need to give up on the standard account of artifact function, according to which function is fixed by design, and replace it with (...) a more context-sensitive account, according to which function attributions depend on the explanatory context and, as a result, categorization also depends on the explanatory context, just as the empirical findings from psychology suggest. I argue that the recent ‘modal theory of function’ originally proposed to explain biological function, is capable of providing such an account of artifact function. (shrink)

In this article, we address the problem of how people understand predicative metaphors such as “The rumor flew through the office,” and argue that predicative metaphors are understood as indirect (or two-stage) categorizations. In the indirect categorization process, the verb (e.g., fly) of a predicative metaphor evokes an intermediate entity, which in turn evokes a metaphoric category of actions or states (e.g., “to spread rapidly and soon disappear”) to be attributed to the target noun (e.g., rumor), rather than directly (...) evoking a metaphoric category as argued by CitationGlucksberg's (2001) categorization theory. We test our argument using two experiments, namely, offline comprehension and online priming. The offline comprehension experiment showed that interpretation of predicative metaphors had greater overlap with words indirectly associated with the verb than those directly associated with the verb. The online priming experiment demonstrated that indirectly associated words were activated during predicative metaphor comprehension, but directly associated words were not. These results provide convergent evidence for our argument, and thus the psychological validity of two-stage categorization as a process of predicative metaphor comprehension was confirmed. (shrink)

I examine the origins of ordinary racial thinking. In doing so, I argue against the thesis that it is the byproduct of a unique module. Instead, I defend a pluralistic thesis according to which different forms of racial thinking are driven by distinct mechanisms, each with their own etiology. I begin with the belief that visible features are diagnostic of race. I argue that the mechanisms responsible for face recognition have an important, albeit delimited, role to play in sustaining this (...) belief. I then argue that essentialist beliefs about race are driven by some of the mechanisms responsible for “entitativity perception”: the tendency to perceive some aggregates of people as more genuine groups than others. Finally, I argue that coalitional thinking about race is driven by a distinctive form of entitativity perception. However, I suggest that more data is needed to determine the prevalence of this form of racial thinking. (shrink)

Recent theoretical work on the psychology of categorization emphasizes the role cognitive constructs play in perception and categorization. This approach supports Putnam's rejection of metaphysical realism. However, the experimental findings concerning basic level categories, in particular, suggest that robust stabilitites among our systems of empirical concepts persist in the face of considerable theoretical diversity and change. These stabilities undermine Putnam's strongest negative conclusions concerning the correspondence theory of truth (once it is uncoupled from metaphysical realism). The centrality (...) of a correspondence criterion of truth (in a larger theory of truth) is psychologically inescapable, rationally indispensable, and (therefore) epistemologically fundamental.

Theories on categorization have led to numerous technical innovations. Starting with artificial intelligence and neural models, scientists have leveraged psychological theories to drive forward innovative technology. More recently, software companies and Internet firms have implemented high technology software developed from cognitive theory. One class of systems rooted in the philosophical tradition stresses the importance of explanation and function. Another focuses on feature similarity and rule-based reasoning. Both approaches have had modest success and solve fundamental problems, but neither has achieved (...) the higher-levels of categorization found in humans. The current paper critically analyzes the various theories of categorization and their collective impact on recent technology innovations. (shrink)

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.

The general question (G) How do we categorize artifacts? can be subject to three different readings: an ontological, an epistemic and a semantic one. According to the ontological reading, asking (G) is equivalent to asking in virtue of what properties, if any, a certain artifact is an instance of some artifact kind: (O) What is it for an artifact a to belong to kind K? According to the epistemic reading, when we ask (G) we are investigating what properties of the (...) object we exploit in order to decide whether a certain artifact belongs to a certain kind. (G) thus becomes: (E) How can we know that artifact a belongs to kind K? Finally, (G) can also be read as a question concerning the semantics of artifact kind terms. The semantic reading of (G) is: (S) What kind of reference do artifact kind terms have, if any? In this editorial we expand on the different answers to (O), (E) and (S) that are given in the selected literature on the topic. The result should give us an overall picture of the possible answers to (G). (shrink)

Contained in the face is a vast body of social information, both fixed and flexible. Across multiple lines of converging evidence it has become increasingly clear that face processing is subject to one of the most potent and best understood of social cognitive phenomena: social categorization. This article reviews this research at the juncture of social psychology and face perception showing the interplay between social categorization and face processing. It lays out evidence indicating that social categories are (...) extracted easily from faces, suggesting that the effects of social categories can occur quickly and unintentionally. Recent evidence that social categories can affect perception of both invariant and variant facial characteristics is discussed. Finally, the article summarizes recent evidence indicating that the motivational consequences of social categories can affect which faces are remembered and how faces are processed. (shrink)

One way to theorize about we-identities—the identities that individual subjects have as ‘one of us’—is in terms of the uniformity, interchangeability, and prototypicality of group members. The social-psychological theory of self-categorization epitomizes this approach, which has strongly influenced contemporary phenomenological research on the we. This paper argues that this approach has one important and largely overlooked limitation: the we-identities tied to close personal relationships—exemplified by long-term friendships and romantic partnerships—are based on patterns of interpersonal interaction and integration through which (...) individuals tend to grasp their non-substitutability and complementarity. This limitation suggests that another approach is needed to tackle the we-identities characteristic of close personal relationships. I outline such an approach, by combining resources from classical phenomenology and ongoing research on the socially extended mind. (shrink)

The purpose of this paper is to present two kinds of analogical representational change, both occurring early in the analogy-making process, and then, using these two kinds of change, to present a model unifying one sort of analogy-making and categorization. The proposed unification rests on three key claims: (1) a certain type of rapid representational abstraction is crucial to making the relevant analogies (this is the first kind of representational change; a computer model is presented that demonstrates this kind (...) of abstraction), (2) rapid abstractions are induced by retrieval across large psychological distances, and (3) both categorizations and analogies supply understandings of perceptual input via construing, which is a proposed type of categorization (this is the second kind of representational change). It is construing that finalizes the unification. (shrink)

Psychology has benefited from an enormous wealth of knowledge about processes of cognition in relation to how the brain organizes information. Within the categorization literature, this behavior is often explained through theories of memory construction called exemplar theory and prototype theory which are typically based on similarity or rule functions as explanations of how categories emerge. Although these theories work well at modeling highly controlled stimuli in laboratory settings, they often perform less well outside of these settings, such (...) as explaining the emergence of background knowledge processes. In order to explain background knowledge, we present a non-similarity-based post-Skinnerian theory of human language called Relational Frame Theory which is rooted in a philosophical world view called functional contextualism. This theory offers a very different interpretation of how categories emerge through the functions of behavior and through contextual cues, which may be of some benefit to existing categorization theories. Specifically, RFT may be able to offer a novel explanation of how background knowledge arises, and we provide some mathematical considerations in order to identify a formal model. Finally, we discuss much of this work within the broader context of general semantic knowledge and artificial intelligence research. (shrink)

This study addresses the issue of artifact kinds from a psychological and cognitive perspective. The primary interest of the investigation lies in understanding how artifacts are categorized and what are the properties people rely on for their identification. According to a classical philosophical definition artifacts form an autonomous class of instances including all and only those objects that do not exist in nature, but are artificial, in the sense that they are made by an artĭfex. This definition suggests that artifacts (...) are classified primarily on the basis of the recognition of their artificial nature. Nevertheless, many psychological and cognitive studies maintain that artifacts are categorized mainly on the basis of the recognition of the function they have been made to accomplish. Since tools are also categorized primarily on the basis of their function, this would imply that artifacts and tools are represented in the same way. In the study participants categorized a set of objects (denoted by words) once as tools and once as artifacts. Results show that reaction times (RTs) are faster in the artifact categorization condition than in the tool categorization condition. This pattern indicates that artifacts and tools are not represented in the same way and that the identification of the members of each class is carried out in the basis of different criteria.

. This paper describes a cross-cultural and developmental research project on naïve or folk biology, that is, the study of how people conceptualize nature. The combination of domain specificity and cross-cultural comparison brings a new perspective to theories of categorization and reasoning and undermines the tendency to focus on “standard populations.” From the standpoint of mainstream cognitive psychology, we find that results gathered from standard populations in industrialized societies often fail to generalize to humanity at large. For example, (...) similarity-driven typicality and diversity effects and basic level phenomena either are not found or pattern differently when we move beyond undergraduates. From the perspective of domain-specificity, standard populations may yield misleading results, because such populations represent examples of especially impoverished experience with respect to nature. Conceptions of humans as biological kinds vary with cultural milieu and input conditions. We also show certain phenomena that are robust across populations, consistent with notions of domain-specificity. (shrink)

One of the core insights from Eleanor Rosch’s work on categorization is that human categorization isn’t arbitrary. Instead, two psychological principles constrain possible systems of classification for all human cultures. According to these principles, the task of a category system is to provide maximum information with the least cognitive effort, and the perceived world provides us with structured rather than arbitrary features. In this paper, I show that Rosch's insights give us important resources for making progress on the (...) 'feasibility question' in conceptual engineering: the question of how we can implement conceptual engineering projects in ways that are practically feasible. Specifically, I show that one overlooked upshot of Rosch's work is that naming practices play an extremely important role in the construction of perceived similarities within and dissimilarities between categories, and, correspondingly, the dissemination of social stereotypes that serve as markers between different categories that are otherwise similar. Thus, naming practices will be a crucial constraint for the feasibility of certain ameliorative projects. (shrink)

Human kinship systems play a central role in social organization, as anthropologists have long demonstrated. Much less is known about how cultural schemas of relatedness are transmitted across generations. How do children learn kinship concepts? To what extent is learning affected by known cross-cultural variation in how humans classify kin? This review draws on research in developmental psychology, linguistics, and anthropology to present our current understanding of the social and cognitive foundations of kinship categorization. Amid growing interest in (...) kinship in the cognitive sciences, the paper aims to stimulate new research on the ontogeny of kinship categorization, a rich domain for studying the nexus of language, culture, and cognition. We introduce an interdisciplinary research toolkit to help streamline future research in this area. (shrink)

We aim to show that far-related primates like humans and the capuchin monkeys show interesting correspondences in terms of artifact characterization and categorization. We investigate this issue by using a philosophically-inspired definition of physical artifact which, developed for human artifacts, turns out to be applicable for cross-species comparison. In this approach an artifact is created when an entity is intentionally selected and some capacities attributed to it (often characterizing a purpose). Behavioral studies suggest that this notion of artifact is (...) not specific to the human kind. On the basis of the results of a series of field observations and experiments on wild capuchin monkeys that routinely use stone hammers and anvils, we show that the notions of intentional selection and attributed capacity appear to be at play in capuchins as well. The study also suggests that functional criteria and contextualization play a fundamental role in terms of artifact recognition and categorization in nonhuman primates. (shrink)

Spatial region concepts such as “front,” “back,” “left,” and “right” reflect our typical interaction with space, and the corresponding surrounding regions have different statuses in memory. We examined the representation of spatial directions in the auditory space, specifically in how far natural response actions, such as orientation movements toward a sound source, would affect the categorization of egocentric auditory space. While standing in the middle of a circle with 16 loudspeakers, participants were presented acoustic stimuli coming from the loudspeakers (...) in randomized order, and verbally described their directions by using the concept labels “front,” “back,” “left,” “right,” “front-right,” “front-left,” “back-right,” and “back-left.” Response actions varied in three blocked conditions: (1) facing front, (2) turning the head and upper body to face the stimulus, and (3) turning the head and upper body plus pointing with the hand and outstretched arm toward the stimulus. In addition to a protocol of the verbal utterances, motion capture and video recording generated a detailed corpus for subsequent analysis of the participants’ behavior. Chi-square tests revealed an effect of response condition for directions within the left and right sides. We conclude that movement-based response actions influence the representation of auditory space, especially within the sides’ regions. Moreover, the representation of auditory space favors the front and the back regions in terms of resolution, which is possibly related to the physiological characteristics of the human auditory system, as well as to the ecological requirements of action control in the different regions.

According to self-categorization theory , incidents of crowd violence can be understood as discrete forms of social action, limited by the crowd's social identity. Through an analysis of the riot at Woodstock 1999, this paper explores the uses and limitations of SCT in order to reach a more complex psychology of crowd behavior, particularly those instances that appear unmotivated, irrational, and destructive. Psychological and sociological literature are synthesized to explore the role of communication in establishing social norms within (...) the crowd. Several modifications to current crowd psychology are proposed, including a false consensus effect of motivation and the mediation of personal and social identities. (shrink)

Many psychological studies of categorization and reasoning use undergraduates to make claims about human conceptualization. Generalizability of findings to other populations is often assumed but rarely tested. Even when comparative studies are conducted, it may be challenging to interpret differences. As a partial remedy, in the present studies we adopt a 'triangulation strategy' to evaluate the ways expertise and culturally different belief systems can lead to different ways of conceptualizing the biological world. We use three groups (US bird experts, (...) US undergraduates, and ordinary Itza' Maya) and two sets of birds (North American and Central American). Categorization tasks show considerable similarity among the three groups' taxonomic sorts, but also systematic differences. Notably, US expert categorization is more similar to Itza' than to US novice categorization. The differences are magnified on inductive reasoning tasks where only undergraduates show patterns of judgment that are largely consistent with current models of category-based taxonomic inference. The Maya commonly employ causal and ecological reasoning rather than taxonomic reasoning. Experts use a mixture of strategies (including causal and ecological reasoning), only some of which current models explain. US and Itza' informants differed markedly when reasoning about passerines (songbirds), reflecting the somewhat different role that songbirds play in the two cultures. The results call into question the importance of similarity-based notions of typicality and central tendency in natural categorization and reasoning. These findings also show that relative expertise leads to a convergence of thought that transcends cultural boundaries and shared experiences. (shrink)

Rebound effects on the consumer level occur when consumers’ realized greenhouse gas emission savings caused by behaviors that might be beneficial to the environment are lower than their potential greenhouse gas emission savings because the savings are offset by behavioral adjustments. While previous literature mainly studied the economic mechanisms of such rebound effects, research has largely neglected the moral-psychological mechanisms. A comprehensive conceptualization of rebound effects on the consumer level can help fill this void and stimulate more empirical research in (...) this relevant area. To this end, the paper introduces three focal dimensions of rebound effects on the consumer level: mechanism of rebound effects, product category, and consumption context. Based on this conceptualization, and integrating assumptions from the theory of moral licensing, the theory of categorization, and the construal level theory, this paper further refines the conceptualization of the moral component as an explanatory factor for rebound effects and highlights that the moral-psychological mechanisms of indirect rebound effects are more complex and diverse than the economic mechanisms. The paper outlines promising directions for future studies considering the different quantification and characteristics of economic and moral currencies that explain rebound effects on the consumer level and the strategic categorization of products and consumption contexts.

Experimental Semiotics (ES) is the study of novel forms of communication that communicators develop in laboratory tasks whose designs prevent them from using language. Thus, ES relates to pragmatics in a “pure,” radical sense, capturing the process of creating the relation between signs and their interpreters as biological, psychological, and social agents. Since such a creation of meaning-making from scratch is of central importance to language evolution research, ES has become the most prolific experimental approach in this field of research. (...) In our paper, we report the results of a study on the scope of recent ES and evaluate the ways in which it is relevant to the study of language origins. We coded for multiple levels across 13 dimensions related to the properties of the emergent communication systems or properties of the study designs, such as type of goal (coordination versus referential), modality of communication, absence or presence of turn-taking, or the presence of vertical vs. horizontal transmission. We discuss our findings and our classification, focusing on the advantages and limitations of those trends in ES, and in particular their ecological validity in the context of bootstrapping communication and the evolution of language.

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)
