Uncovering the diverse cultural bases of social identity: Ingroup ties predict self‐stereotyping among individualists but not among collectivists

On what basis do people form their social identities? To investigate this issue, the present research investigates cross‐cultural differences in self‐stereotyping, a key outcome of social identification. In particular, the research tests the hypothesis that ingroup ties are a stronger predictor of self‐stereotyping among people from individualist cultures than among people from collectivist cultures. In Study 1, university students (N = 117) completed measures of ingroup ties and self‐stereotyping with respect to an intimacy group (family and friends). Consistent with predictions, ingroup ties significantly predicted self‐stereotyping among individualists but not among collectivists. Study 2 (N = 104) found a similar pattern of results among members of the global internet community who considered either an intimacy group (their friends), a task group (their work group) or a social category (their gender). These results indicate that people in individualist cultures are more likely than those in collectivist cultures to base their social identities on ingroup ties. The implications of these results are discussed in relation to self‐categorization theory's depersonalization account of social identification.     

Conceptual Integration of Arithmetic Operations With Real‐World Knowledge: Evidence From Event‐Related Potentials

Research on language processing has shown that the disruption of conceptual integration gives rise to specific patterns of event‐related brain potentials (ERPs)—N400 and P600 effects. Here, we report similar ERP effects when adults performed cross‐domain conceptual integration of analogous semantic and mathematical relations. In a problem‐solving task, when participants generated labeled answers to semantically aligned and misaligned arithmetic problems (e.g., 6 roses + 2 tulips  = ? vs. 6 roses + 2 vases  = ?), the second object label in misaligned problems yielded an N400 effect for addition (but not division) problems. In a verification task, when participants judged arithmetically correct but semantically misaligned problem sentences to be “unacceptable,” the second object label in misaligned sentences elicited a P600 effect. Thus, depending on task constraints, misaligned problems can show either of two ERP signatures of conceptual disruption. These results show that well‐educated adults can integrate mathematical and semantic relations on the rapid timescale of within‐domain ERP effects by a process akin to analogical mapping.     

Historical Semantic Chaining and Efficient Communication: The Case of Container Names

Semantic categories in the world's languages often reflect a historical process of chaining: A name for one referent is extended to a conceptually related referent, and from there on to other referents, producing a chain of exemplars that all bear the same name. The beginning and end points of such a chain might in principle be rather dissimilar. There is also evidence supporting a contrasting picture: Languages tend to support efficient, informative communication, often through semantic categories in which all exemplars are similar. Here, we explore this tension through computational analyses of existing cross‐language naming and sorting data from the domain of household containers. We find (a) formal evidence for historical semantic chaining, and (b) evidence that systems of categories in this domain nonetheless support near‐optimally efficient communication. Our results demonstrate that semantic chaining is compatible with efficient communication, and they suggest that chaining may be constrained by the functional need for efficient communication.     

Evidence for task-dependent categorization in infancy

Two experiments compared infants' attention to the categorical distinction between people and animals in object-examining and sequential-touching tasks. In Experiment 1, 10- and 13-month-old infants distinguished between animals and people in an object-examining task. In this task, infants are familiarized with individual exemplars from one category, and then their response to exemplars from another category is measured. In Experiment 2, 13- and 16-month-old infants, but not 10-month-old infants, attended to the same distinction in a sequential-touching task. In this task, infants are presented with several exemplars from two categories simultaneously, and the order in which they touch those objects is assessed. Evaluation of infants' touching behavior in Experiment 2 also revealed developmental changes in how they approached this task. The combined results of these two experiments confirm the general trend reported in the literature and begin to provide insight into developmental changes that contribute to infants' ability to apply their categorization skills in different task contexts.     

On the existence of prelinguistic categories: A case study

The purpose of this study was to investigate whether infants spontaneously form categories during the prelinguistic period and whether these categories are based on the same principles as adult basic-level categories. A new methodology, using a functional use measure as the determinant of category composition, was employed in a case study of one infant's horn category. Results indicated that this category met Schlesinger's (1982) criteria for a prelinguistic category and that the category was based on similarity relationships, as adult categories are.     

Detection of gender-related categories by 10-month-old infants

Thirty-two 10-month-olds completed an habituation procedure where a male or female face was paired with a specific object. Results reveal 10-month-olds can form categories based on correlations among attributes of social information. Basic processes involved in gender role formation are present in 10-month-olds.     

What's in an accent? General spontaneous biases against nonnative accents: An investigation with conceptual and auditory IATs

Nonnative accents are prevalent in our globalized world and constitute highly salient cues in social perception. Whereas previous literature has commonly assumed that they cue specific social group stereotypes, we propose that nonnative accents generally trigger spontaneous negatively biased associations (due to a general nonnative accent category and perceptual influences). Accordingly, Study 1 demonstrates negative biases with conceptual IATs, targeting the general concepts of accent versus native speech, on the dimensions affect, trust, and competence, but not on sociability. Study 2 attests to negative, largely enhanced biases on all dimensions with auditory IATs comprising matched native–nonnative speaker pairs for four accent types. Biases emerged irrespective of the accent types that differed in attractiveness, recognizability of origin, and origin‐linked national associations. Study 3 replicates general IAT biases with an affect IAT and a conventional evaluative IAT. These findings corroborate our hypotheses and assist in understanding general negativity toward nonnative accents.     

Simple Co‐Occurrence Statistics Reproducibly Predict Association Ratings

What determines human ratings of association? We planned this paper as a test for association strength (AS) that is derived from the log likelihood that two words co‐occur significantly more often together in sentences than is expected from their single word frequencies. We also investigated the moderately correlated interactions of word frequency, emotional valence, arousal, and imageability of both words (r's ≤ .3). In three studies, linear mixed effects models revealed that AS and valence reproducibly account for variance in the human ratings. To understand further correlated predictors, we conducted a hierarchical cluster analysis and examined the predictors of four clusters in competitive analyses: Only AS and word2vec skip‐gram cosine distances reproducibly accounted for variance in all three studies. The other predictors of the first cluster (number of common associates, (positive) point‐wise mutual information, and word2vec CBOW cosine) did not reproducibly explain further variance. The same was true for the second cluster (word frequency and arousal); the third cluster (emotional valence and imageability); and the fourth cluster (consisting of joint frequency only). Finally, we discuss emotional valence as an important dimension of semantic space. Our results suggest that a simple definition of syntagmatic word contiguity (AS) and a paradigmatic measure of semantic similarity (skip‐gram cosine) provide the most general performance‐independent explanation of association ratings.     

Teaching oddity and insertion to Head Start children: An economical cognitive intervention

Two interventions were offered to Head Start preschoolers. Half of the children played numerous learning set games designed to teach the children (1) the oddity principle and (2) how to insert objects into a series. Mastery of these concepts is theoretically an important aspect of school readiness. The other half of the children engaged in the I Can Problem Solve (ICPS) exercises, a program designed to increase the children's competency in recognizing and responding to other people's feelings. The children who played the learning set games became superior at oddity and insertions with manipulable objects, and generalized these games to workbook-like formats resembling those encountered in kindergarten. They also scored higher on the numeracy and memory scales of the McCarthy Scales of Children's Abilities, indicating that mastery of oddity and insertions may have served as foundations for further cognitive growth. The children who participated in the ICPS exercises became superior at creating solutions to interpersonal problems, as measured by the Preschoolers Interpersonal Problem Solving Scale. The differences in the outcomes indicate that both interventions were successful in their own domains. The advantage the cognitive intervention produced on the McCarthy Scales suggests that oddity and insertion abilities may be a foundation in fact as well as in theory for general cognitive growth at this age.
