Not all categorization is conceptual. Many of the experimental findings concerning infant and animal categorization invite the hypothesis that the subjects form abstract perceptual representations, mental models or cognitive maps that are not composed of concepts. The paper is a reflection upon the idea that conceptual categorization involves the ability to make categorical judgements under the guidance of norms of rationality. These include a norm of truth-seeking and a norm of good evidence. Acceptance of these norms implies (...) willingness to defer to cognitive authorities, unwillingness to commit oneself to contradictions, and knowledge of how to reorganize one's representational system upon discovering that one has made a mistake. It is proposed that the cognitive architecture required for basic rationality is similar to that which underlies pretend-play. The representational system must be able to make room for separate 'mental spaces' in which alternatives to the actual world are entertained. The same feature underlies the ability to understand modalities, time, the appearance-reality distinction, other minds, and ethics. Each area of understanding admits of degrees, and mastery takes years. But rational concept-management, at least in its most rudimentary form, does not require a capacity to form second-order representations. It requires knowledge of how to operate upon, and compare, the contents of different mental spaces.Nem toda categorização é conceitual. Muitas das descobertas experimentais sobre o processo de categorização nas crianças e animais sugerem a hipótese segundo a qual os sujeitos formam representações perceptuais abstratas, modelos mentais ou mapas cognitivos que não são compostos de conceitos. Este artigo é uma reflexão acerca da ideia de que categorização conceitual envolve a habilidade de fazer julgamentos categoriais, tender como guia as normas de racionalidade. Estas incluem uma norma de busca da verdade e uma norma de evidência adequada. A aceitação dessas normas implica boa vontade em respeitar as autoridades cognitivas, o desejo de evitar as contradições e o conhecimento de como reorganizar seu sistema representacional após descobrir que se cometeu um erro. Sugere-se que a arquitetura cognitiva requerida pela racionalidade básica é semelhante àquela subjacente ao jogo do "faz de conta". O sistema representacional deve ser capaz de arrumar lugar para "espaços mentais", nos quais alternativas para o mundo real são consideradas. A mesma característica subjaz à habilidade de compreender modalidades, tempo, a distinção entre aparência e realidade, outras mentes e éticas. Cada área de compreensão admite graus, e o seu domínio leva anos. Contudo a manipulação racional de conceitos, pelo menos na sua forma mais rudimentar, não requer a capacidade de formar representações de segunda ordem. Ela requer conhecimento do procedimento de como operar e comparar os conteúdos dos diferentes espaços mentais. (shrink)

There is controversy as to whether children with developmental language disorder (DLD) and those with high-functioning autism plus language impairment (HFA-LI) share similar language profiles. This study investigated the similarities and differences in the production of Chinese negative sentences by children with DLD and children with HFA-LI to provide evidence relevant to this controversy. The results reflect a general resemblance between the two groups in their lower-than-TDA (typically developing age-matched) performance. Both groups encountered difficulties in using negative (...) markers, which suggests that they might be impaired in feature agreement. Slight differences were detected between the two groups. Specifically, children with DLD experienced difficulties with the agreement on the feature [+telic] and that on the feature [+dynamic], while children with HFA-LI had difficulties with the agreement on the feature [+dynamic] and that on the feature [−dynamic]. This study supports the idea of a common symptomatology for the two disorders. More importantly, it suggests that these two disorders, DLD and HFA-LI, are not altogether the same in terms of language impairment. This paper concludes that general labels should not be simply attached to any children with language disorders. Instead, atypical language is very worthy of further analysis in the categorization of language disorders. (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.

Multisensory integration allows us to link sensory cues from multiple sources and plays a crucial role in speech development. However, it is not clear whether humans have an innate ability or whether repeated sensory input while the brain is maturing leads to efficient integration of sensory information in speech. We investigated the integration of auditory and somatosensory information in speech processing in a bimodal perceptual task in 15 young adults (age 19 to 30) and 14 children (age 5 to (...) 6). The participants were asked to identify if the perceived target was the sound /e/ or /ø/. Half of the stimuli were presented under a unimodal condition with only auditory input. The other stimuli were presented under a bimodal condition with both auditory input and somatosensory input consisting of facial skin stretches provided by a robotic device, which mimics the articulation of the vowel /e/. The results indicate that the effect of somatosensory information on sound categorization was larger in adults than in children. This suggests that integration of auditory and somatosensory information evolves throughout the course of development. (shrink)

Two experiments examined the impact of causal relations between features on categorization in 5‐ to 6‐year‐old children and adults. Participants learned artificial categories containing instances with causally related features and noncausal features. They then selected the most likely category member from a series of novel test pairs. Classification patterns and logistic regression were used to diagnose the presence of independent effects of causal coherence, causal status, and relational centrality. Adult classification was driven primarily by coherence when causal links (...) were deterministic (Experiment 1) but showed additional influences of causal status when links were probabilistic (Experiment 2). Children’s classification was based primarily on causal coherence in both cases. There was no effect of relational centrality in either age group. These results suggest that the generative model (Rehder, 2003a) provides a good account of causal categorization in children as well as adults. (shrink)

Children ask many questions, but do not always receive answers to the questions they ask. We were interested in whether the act of generating questions, in the absence of an answer, is related to children’s later thinking. Two experiments examined whether children retain the questions they ask in working memory, and whether the type of questions asked relate to their categorization. Four to ten-year-old children were shown 12 novel objects, asked three questions about each, and (...) did not receive answers to their questions. Children recalled their questions in the first experiment and categorized variants of the novel objects in the second experiment. We found that children have robust working memory for their questions, indicating that these questions may relate to their subsequent thinking. Additionally, children generalize category boundaries more narrowly or broadly depending on the type of question they ask, indicating that children’s questions may reflect an underlying bias in how they think about the world. These findings suggest that future research should examine questions in the absence of answers to understand how inquiry affects children’s cognitive development. (shrink)

Flags are conceptual representations that can prime nationalism and allegiance to one’s group. Investigating children’s understanding of conflict-related ethno-national flags in divided societies sheds light on the development of national categories. We explored the development of children’s awareness of, and preferences for, ethno-national flags in Northern Ireland, Kosovo, and the Republic of North Macedonia. Children displayed early categorization of, and ingroup preferences for, ethno-national flags. By middle-childhood, children’s conflict-related social categories shaped systematic predictions about other’s (...) group-based preferences for flags. Children of minority-status groups demonstrated more accurate flag categorization and were more likely to accurately infer others’ flag preferences. While most Balkan children preferred divided versus integrated ethno-national symbols, children in the Albanian majority group in Kosovo demonstrated preferences for the new supra-ethnic national flag. We discuss the implications of children’s ethno-national flag categories on developing conceptualizations of nationality and the potential for shared national symbols to promote peace. (shrink)

The Archaeology of Semiotics and the social order of things is edited by George Nash and George Children and brings together 15 thought-provoking chapters from contributors around the world. A sequel to an earlier volume published in 1997, it tackles the problem of understanding how complex communities interact with landscape and shows how the rules concerning landscape constitute a recognised and readable grammar. The mechanisms underlying landscape grammar are both physical and mental, being based in part on the mindset (...) of the individual; the same landscape can thus evoke different meanings for different people and at different times. People's perception has greatly influenced the construction of landscapes over millennia but, until recently, the potential of this area has been largely untapped. Apart from chapters focusing solely upon human interaction with landscape, there are several which skilfully integrate artefacts and place with landscape (e.g. Gheorghiu and Sognnes). Other chapters look at the way people have marked the landscape through such mechanisms as rock-art (e.g. Clegg, Devereux, Estévez, Fossati, Kelleher and Skier). Rock-art establishes personal and communal identity in relation to landscape and it is clear that other forms of visual expression were in place which distinctively created special places within the landscape. Landscape constructs can bind cultures together; bringing the old ways of reading the landscape into contemporary life (e.g. Smiseth). Defining early and late prehistoric landscapes and segregating these into, say, mundane domestic and ritualised spaces rely on both clear and subtle archaeologies and in this volume distinct monument clustering and ritualised linearity are considered (e.g. Mason and Nash). A volume such as this cannot escape the influence of New World approaches, such as anthropology, and in many respects chapters by Bender, Muller and Merritt give context to other chapters within the book. Finally, one must consider text as a means of constructing landscape and this is considered by Heyd, who eloquently deconstructs the travel diary of a 17th century Japanese poet. This will be an important volume for archaeologists, landscape scholars and students. The many approaches used are tried and tested, forming an invaluable resource and not just another edited book.

Social categorization is an early emerging and robust component of social cognition, yet the role that social categories play in children's understanding of the social world has remained unclear. The present studies examined children's explanations of social behavior to provide a window into their intuitive theories of how social categories constrain human action. Children systematically referenced category memberships and social relationships as causal-explanatory factors for specific types of social interactions: harm among members of different categories more (...) than harm among members of the same category. In contrast, they systematically referred to agents' mental states to explain the reverse patterns of behaviors: harm among members of the same category more than harm among members of different categories. These data suggest that children view social category memberships as playing a causal-explanatory role in constraining social interactions. (shrink)

Children usually use the external and physical features of characters in movies or stories as a means of categorizing them quickly as being either good or bad/evil. This categorization is probably done by means of heuristics and previous experience. However, the study of this fast processing is difficult in children. In this paper, we propose a new experimental paradigm to determine how these decisions are made. We used illustrations of characters in folk tales, whose visual representations contained (...) features that were compatible or incompatible with the moral identity of the characters. Sixteen children between 8 and 10 years old participated in the experiment. We measured their electrodermal activity when they were listening to the story and looking at pictures of the characters. Results revealed a higher increase in skin conductance when the illustrations showed a moral condition that was incompatible with the actions of a character than when they showed one that was compatible. These results suggest that children make fast decisions about the moral identity of characters based on their physical features. They open up new possibilities in the study of the processing of moral decisions in children. (shrink)

In German, nouns are assigned to one of the three gender classes. For most animal names, however, the assignment is independent of the referent’s biological sex. We examined whether German-speaking children understand this independence of grammar from semantics or whether they assume that grammatical gender is mapped onto biological sex when drawing inferences about sex-specific biological properties of animals. Two cross-linguistic studies comparing German-speaking and Japanese-speaking preschoolers were conducted. The results suggest that German-speaking children utilize grammatical gender as (...) a cue for inferences about sex-specific properties of animals. Further, we found that Japanese- and German-speaking children recruit different resources when drawing inferences about sex-specific properties: Whereas Japanese children paralleled their pattern of inference about properties common to all animals, German children relied on the grammatical gender class of the animal. Implications of these findings for studying the relation between language and thought are discussed. (shrink)

Based on evidence that learning new characters through handwriting leads to better recognition than learning through typing, some authors proposed that the graphic motor plans acquired through handwriting contribute to recognition. More recently two alternative explanations have been put forward. First, the advantage of handwriting could be due to the perceptual variability that it provides during learning. Second, a recent study suggests that detailed visual analysis might be the source of the advantage of handwriting over typing. Indeed, in that study, (...) handwriting and composition –a method requiring a detailed visual analysis but no specific graphomotor activity– led to equivalent recognition accuracy, both higher than typing. The aim of the present study was to assess whether the contribution of detailed visual analysis is observed in preschool children and to test the variability hypothesis. To that purpose, three groups of preschool children learned new symbols either by handwriting, typing, or composition. After learning, children performed first a four-alternative recognition task and then a categorization task. The same pattern of results as the one observed in adults emerged in the four-alternative recognition task, confirming the importance of the detailed visual analysis in letter-like shape learning. In addition, results failed to reveal any difference across learning methods in the categorization task. The latter results provide no evidence for the variability hypothesis which would predict better categorization after handwriting than after typing or composition. (shrink)

We present a series of three analyses of young children's linguistic input to determine the distributional information it could plausibly offer to the process of grammatical category learning. Each analysis was conducted on four separate corpora from the CHILDES database (MacWhinney, 2000) of speech directed to children under 2;5. We showthat, in accord with other findings, a distributional analysis which categorizeswords based on their co‐occurrence patterns with surroundingwords successfully categorizes the majority of nouns and verbs. In Analyses 2 (...) and 3, we attempt to make our analyses more closely relevant to natural language acquisition by adopting more realistic assumptions about howyoung children represent their input. In Analysis 2, we limit the distributional context by imposing phrase structure boundaries, and find that categorization improves even beyond that obtained from less limited contexts. In Analysis 3, we reduce the representation of input elements which young children might not fully process and we find that categorization is not adversely affected: Although noun categorization is worse than in Analyses 1 and 2, it is still good; and verb categorization actually improves. Overall, successful categorization of nouns and verbs is maintained across all analyses. These results provide promising support for theories of grammatical category formation involving distributional analysis, as long as these analyses are combined with appropriate assumptions about the child learner's computational biases and capabilities.

It is unclear how children learn labels for multiple overlapping categories such as “Labrador,” “dog,” and “animal.” Xu and Tenenbaum suggested that learners infer correct meanings with the help of Bayesian inference. They instantiated these claims in a Bayesian model, which they tested with preschoolers and adults. Here, we report data testing a developmental prediction of the Bayesian model—that more knowledge should lead to narrower category inferences when presented with multiple subordinate exemplars. Two experiments did not support this prediction. (...) Children with more category knowledge showed broader generalization when presented with multiple subordinate exemplars, compared to less knowledgeable children and adults. This implies a U-shaped developmental trend. The Bayesian model was not able to account for these data, even with inputs that reflected the similarity judgments of children. We discuss implications for the Bayesian model, including a combined Bayesian/morphological knowledge account that could explain the demonstrated U-shaped trend. (shrink)

We report on rapid perceptual learning of intonation contour categories in adults and 9- to 11-year-old children. Intonation contours are temporally extended patterns, whose perception requires temporal integration and therefore poses significant working memory challenges. Both children and adults form relatively abstract representations of intonation contours: Previously encountered and novel exemplars are categorized together equally often, as long as distance from the prototype is controlled. However, age-related differences in categorization performance also exist. Given the same experience, adults (...) form narrower categories than children. In addition, adults pay more attention to the end of the contour, while children appear to pay equal attention to the beginning and the end. The age range we examine appears to capture the tail-end of the developmental trajectory for learning intonation contour categories: There is a continuous effect of age on category breadth within the child group, but the oldest children are adult-like.

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)

Establishing healthy dietary habits in childhood is crucial in preventing long-term repercussions, as a lack of dietary variety in childhood leads to enduring impacts on both physical and cognitive health. Poor conceptual knowledge about food has recently been shown to be a driving factor of food rejection. The majority of studies that have investigated the development of food knowledge along with food rejection have mainly focused on one subtype of conceptual knowledge about food, namely taxonomic categories. However, taxonomic categorization (...) is not the only way to understand the food domain. We also heavily rely on other conceptual structures, namely thematic associations, in which objects are grouped because they share spatial-temporal properties or exhibit a complementary relationship. We rely on such thematic associations between food items, which may not fall into the same taxon, to determine the acceptability of food combinations. However, the development of children's ability to master these relations has not been systematically investigated, nor alongside the phenomenon of food rejection. The present research aims to fill this gap by investigating the development of conceptual food knowledge and the putative relationship between children's food rejection and both thematic and taxonomic food knowledge. A proportional analogy task, with a choice between taxonomic and thematic food associates, was conducted on children between 3 and 7-years-old. The children were systematically presented with either a thematic or taxonomic food base pair and then asked to extend the example type of relation to select the respective thematic or taxonomic match to the target. Our results revealed, for the first time, that increased levels of food rejection were significantly predictive of poorer food identification and decreased thematic understanding. These findings entitle us to hypothesize that knowledge-based food education programs to foster dietary variety in young children, should not only aim to improve taxonomic understanding of food, but also thematic relations.

While justifications are used frequently by young children in their everyday interactions, their use has not been examined to any great extent. This article examines the interactional phenomenon of justification used by young children as they manage social organization of their peer group in an early childhood classroom. The methodological approaches of conversation analysis and membership categorization analysis were used to analyse video-recorded and transcribed interactions of young children in a preparatory classroom in a primary school (...) in Australia. The focus is an episode that occurred within the play area of the classroom and involved a dispute of ownership relating to a small, wooden plank. Justifications were frequent occurrences as the young participants drew upon justificatory devices to support their stances. The justifications related to the concepts of ownership and were used by those engaged in the particular dispute to support their positions and provide reasons for their actions. Four types of justificatory responses using child-constructed rules are highlighted. They are: justification based on the rule of transferred ownership; the rule of first possession; rules associated with custodianship; and the rule of third-party verification. The justifications are practices that work to build and reinforce individual children's status within the group, which in turn contributes to the social order of the classroom. (shrink)

In this paper, we investigate the informativeness of 4- to 6-year-old children’s questions using a combined qualitative and quantitative approach. Children were presented with a hierarchical version of the 20-questions game, in which they were given an array of objects that could be organized into three category levels based on shared features. We then tested whether it is possible to scaffold children’s question-asking abilities without extensive training. In particular, we supported children’s categorization performance by providing (...) the object-related features needed to ask effective constraint-seeking questions. We found that with both age and scaffolding children asked more effective questions, targeting higher category levels and therefore reaching the solution with fewer questions. We discuss the practical and theoretical implications of these results. (shrink)

Household confinement due to the rapid spread of the pandemic caused by COVID-19 has brought very significant changes, such as the forced stay-at-home of children due to the closure of schools. This has meant drastic changes in the organization of daily life and restrictions on their activities, including exercise, which could affect the quality of life of the children due to its importance. In order to study the relationship between physical activity and psychological well-being of minors, a study (...) has been carried out with Mixed Methods Research, combining survey methodology with transversal design with qualitative methodology using discourse analysis. A total of 234 parents of minors in Spain and several Spanish-speaking countries in America participated. The instrument was a questionnaire in Google Forms, which included the Kidscreen-27 quality of life scale. The results show significant differences in both the type of physical activity and its frequency due to age, and differences in parents’ perception of whether their children’s physical activity levels were sufficient or not, both on the health, mood and school subscales, and in the categorization of open responses referring to concerns due to the pandemic, analyzed with the ALCESTE technique. The relationship between physical activity of children and adolescents and quality of life is clearly concluded. (shrink)

Behavioral scientists routinely publish broad claims about human psychology and behavior in the world's top journals based on samples drawn entirely from Western, Educated, Industrialized, Rich, and Democratic (WEIRD) societies. Researchers – often implicitly – assume that either there is little variation across human populations, or that these “standard subjects” are as representative of the species as any other population. Are these assumptions justified? Here, our review of the comparative database from across the behavioral sciences suggests both that there is (...) substantial variability in experimental results across populations and that WEIRD subjects are particularly unusual compared with the rest of the species – frequent outliers. The domains reviewed include visual perception, fairness, cooperation, spatial reasoning, categorization and inferential induction, moral reasoning, reasoning styles, self-concepts and related motivations, and the heritability of IQ. The findings suggest that members of WEIRD societies, including young children, are among the least representative populations one could find for generalizing about humans. Many of these findings involve domains that are associated with fundamental aspects of psychology, motivation, and behavior – hence, there are no obviousa priorigrounds for claiming that a particular behavioral phenomenon is universal based on sampling from a single subpopulation. Overall, these empirical patterns suggests that we need to be less cavalier in addressing questions ofhumannature on the basis of data drawn from this particularly thin, and rather unusual, slice of humanity. We close by proposing ways to structurally re-organize the behavioral sciences to best tackle these challenges. (shrink)

Categorization of sensory stimuli is a vital process in understanding the world. In this paper we show that distributional learning plays a role in learning novel object categories in school-aged children. An 11-step continuum was constructed based on two novel animate objects by morphing one object into the other in 11 equal steps. Forty-nine children were subjected to one of two familiarization conditions during which they saw tokens from the continuum. The conditions differed in the position of (...) the distributional peaks along the continuum. After familiarization it was tested how the children categorized the stimuli. Results show that, in line with our expectations, familiarization condition influenced categorization during the test phase, indicating that the frequency distribution of tokens in the input had induced novel object category formation. These results suggest that distributional learning could play an important role in categorizing sensory stimuli throughout life. (shrink)

More than a decade of experimental research confirms that external linguistic information provided in the form of word labels can induce a "mutually exclusive" bias against double naming and lead children to infer the name of novel objects and parts. Linguistic labels have also been shown to encourage more sophisticated reasoning, particularly with respect to superordinate and atypical object categorization. By contrast, however, the inverse possibility that the linguistic labeling of basic-level objects may also developmentally support the kind (...) of "phonological reorganization" observed within infant speech categorization has yet to be theoretically isolated and experimentally explored. Yet the dynamic of relying on labels to inform object categorization clearly presupposes that potential word labels themselves have already been classified into language-specific phonemic categories. However, a two-staged strategy of first relying on basic-level object categories to refine speech categorization, and then exploiting such learned speech categories to fine tune object categorization would reveal a cyclically opportunistic learner. A uniform assumption of a one to one pairing between words and objects allows bootstrapping not only from language to object classification, but also from basic object categorization to phonemic speech classification.

Experiments using a preferential looking method, a perceptual judgment method, and a predictive judgment method investigated the development, from 7 months to 6 years of age, of sensitivity to the effects of gravity and inertia on inanimate object motion. The experiments focused on a situation in which a ball rolled off a flat surface and either continued in linear motion (contrary to gravity), turned abruptly and moved downward (contrary to inertia), or underwent natural, parabolic motion. When children viewed the (...) three fully visible motions, both the preferential looking method and the perceptual judgment method provided evidence that sensitivity to inertia developed between 7 months and 2 years, and that sensitivity to gravity began to develop after 3 years. When children predicted the future location of the object without viewing the motions, the predictive judgment method provided evidence that sensitivity to gravity had developed by 2 years, whereas sensitivity to inertia began to develop only at 5±6 years. These findings suggest that knowledge of object motion develops slowly over childhood, in a piecemeal fashion. Moreover, the same system of knowledge appears to be tapped both in preferential looking tasks and in judgment tasks when children view fully visible events, but a different system may underlie children's inferences about unseen object motions.

Audiovisual interaction in speech perception is well defined in adults. Despite the large body of evidence suggesting that children are also sensitive to visual input, very few empirical studies have been conducted. To further investigate whether visual inputs influence auditory perception of phonemes in preschoolers in the same way as in adults, we conducted an audiovisual identification test. The auditory stimuli were presented either in an auditory condition only or simultaneously with a visual presentation of the articulation of the (...) vowel /e/ or /ø/. The results suggest that, although all participants experienced visual influence on auditory perception, substantial individual differences exist in the 5- to 6-year-old group. While additional work is required to confirm this hypothesis, we suggest that auditory and visual systems are developing at that age and that multisensory phonological categorization of the rounding contrast took place only in children whose sensory systems and sensorimotor representations were mature.

The history of the concept of “religion” in Western tradition has intrigued scholars for years. This important collection of eighteen essays brings further light to the ongoing debate. Three of the invited participants, W.C. Smith, M. Despland and E. Feil, has each previously written impressive books treating this subject; the last two acknowledged the impact and continuing influence of Smith’s work, The Meaning and End of Religion. An introduction and a recapitulation of Smith’s contribution as a scholar set the stage (...) for a retrospective look at the published literature. Contributors then examine the transformation of words (the classical religio to the modern religion), particularities of religion in nineteenth-century France, Troeltsch’s concept of religion, the study of religion from an Asian point of view and the categorization of “World Religions.” The concluding essays elaborate contemporary anthropological, cross-disciplinary, semiological, deconstructive and psychoanalytical methodological approaches to the concept and study of “religion.” Exploring critically different aspects of the concept and study of religion, these provocative essays typically reflect the methodological pluralism currently existing in the field of Religious Studies. Of interest to scholars and students alike, this collection also contains a complete bibliography of W.C. Smith’s publications. (shrink)

Generic language (e.g., “tigers have stripes”) leads children to assume that the referenced category (e.g., tigers) is inductively informative and provides a causal explanation for the behavior of individual members. In two preregistered studies with 4- to 7-year-old children (N = 497), we considered the mechanisms underlying these effects by testing how correcting generics might affect the development of these beliefs about novel social and animal kinds (Study 1) and about gender (Study 2). Correcting generics by narrowing their (...) scope to a single individual limited beliefs that the referenced categories could explain what their members would be like while broadening the scope to a superordinate category (Study 2) uniquely limited endorsement of gender norms. Across both studies, correcting generics did not alter beliefs about feature heritability and had mixed effects on inductive inferences, suggesting that additional mechanisms (e.g., causal reasoning about shared features) contribute to the development of full-blown essentialist beliefs. These results help illuminate the mechanisms by which generics lead children to view categories as having rich inductive and causal potential; in particular, they suggest that children interpret generics as signals that speakers in their community view the referenced categories as meaningful kinds that support generalization. The findings also point the way to concrete suggestions for how adults can effectively correct problematic generics (e.g., gender stereotypes) that children may hear in daily life. (shrink)

Despite early emerging and impressive linguistic abilities, young children demonstrate ostensibly puzzling beliefs about the nature of language. In some circumstances monolingual children even express the belief that an individual's language is more stable than her race. The present research investigated bilingual children's thinking about the relative stability of language and race. Five-to six-year-old bilingual children were asked to judge whether a target child who varied in race and language would grow up to be an adult (...) who maintained the target child's race or her language. Similar to many monolingual children, a heterogeneous group of bilingual children on average chose the language-match. Yet French-English bilingual children were relatively more likely to choose the race-match, especially when tested in their non-dominant language. Specific experience with relevant languages, and communicating in a non-dominant language, may contribute to children's developing metalinguistic success and their thinking about social categorization.

This article discusses the ways in which a group of four-year-old children co-constructed friendship networks when they began primary school in Wales, UK. This discussion has emanated from a wider study of the everyday social interactions children engage in when new to their school environment. The children’s interactions were investigated through the use of an inductive, ethnomethodological approach through the combination of conversation analysis and membership categorization analysis. The transcriptions revealed that the children used the (...) collective pro-terms ‘we’ and ‘us’ in order to explicate affiliations and exclusions with their peers in their everyday social interactions. These findings offer an insight into the daily social organization processes children engage in and suggests their preference for exclusive dyadic friendships. The article also reveals the social competencies which four-year-old children have in accomplishing social organization. (shrink)

Abstract Since their inception, distributional models of semantics have been criticized as inadequate cognitive theories of human semantic learning and representation. A principal challenge is that the representations derived by distributional models are purely symbolic and are not grounded in perception and action; this challenge has led many to favor feature-based models of semantic representation. We argue that the amount of perceptual and other semantic information that can be learned from purely distributional statistics has been underappreciated. We compare the representations (...) of three feature-based and nine distributional models using a semantic clustering task. Several distributional models demonstrated semantic clustering comparable with clustering-based on feature-based representations. Furthermore, when trained on child-directed speech, the same distributional models perform as well as sensorimotor-based feature representations of children’s lexical semantic knowledge. These results suggest that, to a large extent, information relevant for extracting semantic categories is redundantly coded in perceptual and linguistic experience. Detailed analyses of the semantic clusters of the feature-based and distributional models also reveal that the models make use of complementary cues to semantic organization from the two data streams. Rather than conceptualizing feature-based and distributional models as competing theories, we argue that future focus should be on understanding the cognitive mechanisms humans use to integrate the two sources.

Many of the errors that occur in children' subtraction are due to the use of incorrect strategies rather than to the incorrect recall of number facts. A production system is presented for performing written subtraction which is consistent with an earlier analysis of the nature of such a cognitive skill. Most of the incorrect strategies used by schoolchildren can be accounted for in a principled way by simple changes in the production system, such as the omission of individual rules (...) or the inclusion of rules appropriate to other arithmetical tasks. The production system model is evaluated against a corpus of over 1500 subtraction problems done by 10‐year olds and is shown to account for about two‐thirds of the (nonnumber fact) errors. It also provides an alternative, simpler interpretation of the subtraction errors analysed by Brown and Burton (1978). Some implications for teaching are discussed. (shrink)

By comparing mechanisms in nativism, empiricism, and culturalism, the target article by Steels & Belpaeme (S&B) emphasizes the influence of communicational constraint on sharing color categories. Our commentary suggests deeper considerations of some of their claims, and discusses some modifications that may help in the study of communicational constraints in both humans and robots.

[We] perform the cultural work of fitting individuals into categories; yet the active labor that goes into making sex appear dichotomous is generally invisible to the broader society, or at least rarely remarked upon.Wording matters. It doesn’t just affect a person’s willingness to check the box and be counted—it also highlights the existence of those identities. Perhaps if we weren’t so regularly confronted with a simple choice—“Are you male or female?”—our thinking about gender wouldn’t be so binary.To be sure, there (...) are truths about bodies.Yet such truths can be expressed without the notion of sex.Contrary to what many people believe, the classificatory system by which sexes are neatly divided into the two...
