We propose that people can and will infer group memberships from resource distributions, and that these distributions have implications for people's understandings of the groups themselves and their own associations with these groups. We derive hypotheses from social identity and self‐categorization theories, and test them in three experiments. In Experiment 1, participants systematically rated specific patterns of group memberships as more likely than others in light of specific resource distributions in a manner consistent with our predictions. In Experiment 2, intragroup distributive fairness led to greater perceived self‐in‐group similarity than intra‐group distributive unfairness, while distributively unfair, in‐group favouritism led to greater perceived self‐in‐group similarity than intergroup fairness. In Experiment 3, social identification dropped following unfair, out‐group favouritism and intragroup unfairness, but not unfair, in‐group favouritism, or intragroup and intergroup fairness. The current data provide support for our hypotheses and clear evidence that resource distributions can be providers of group membership information. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

The question whether executive function (EF) deficits in children are associated with conduct problems remains controversial.
Although the origins of aggressive behavior are to be found in early childhood, findings from EF studies in preschool children
with aggressive behavior are inconsistent. The current study aimed to investigate whether preschool children with aggressive
behavior show impairments in EF. From a population-based sample, 82 preschool children who were showing aggressive behavior
as indicated by scores at or above the 93rd percentile on the Aggressive Behavior Scale of the CBCL 1 1/2-5 were selected.
These children with aggressive behavior were matched on IQ to a group of typically developing control children (N = 99). Six neuropsychological tasks were administered to assess set shifting, inhibition, working memory and verbal fluency.
A factor analysis was conducted which yielded one clear factor: inhibition. Aggressive preschool children showed poorer performance
on this inhibition factor than control children and boys performed worse on this factor than girls. This association between
aggressive behavior and inhibition deficits was maintained after controlling for attention problems. In addition, gender differences
in all EFs measured were found with boys exhibiting more impairment in EF than girls. These findings demonstrate that preschool
children with aggressive behavior show impairments in inhibition, irrespective of attention problems. 相似文献

We examined the effects of sensorimotor experience in two visual word recognition tasks. Body-object interaction (BOI) ratings were collected for a large set of words. These ratings assess perceptions of the ease with which a human body can physically interact with a word's referent. A set of high BOI words (e.g., mask) and a set of low BOI words (e.g., ship) were created, matched on imageability and concreteness. Facilitatory BOI effects were observed in lexical decision and phonological lexical decision tasks: responses were faster for high BOI words than for low BOI words. We discuss how our findings may be accounted for by (a) semantic feedback within the visual word recognition system, and (b) an embodied view of cognition (e.g., Barsalou's perceptual symbol systems theory), which proposes that semantic knowledge is grounded in sensorimotor interactions with the environment. 相似文献

Objectification theory suggests that women internalize an observer’s perspective on the body (self objectification; Fredrickson and Roberts, Psychol Women Q 22:173–206, 1997); however, certain contexts and thoughts may make self-objectification more likely. Because the pursuit of relationships is tied to attractiveness, the present study examines whether women have an automatic link between self-objectification and romantic relationships. Using a US undergraduate sample, women (N?=?86) of different relationship statuses were either exposed to relationship-related or neutral words in a lexical decision making task. Following relationship priming, single women showed greater self-objectification and women in relationships showed less self-objectification. These findings are discussed in terms of self-objectification theory and the importance of attractiveness and beauty in the pursuit of relationships. 相似文献

Social satisfaction in late adulthood originates from competing sources. Older adults tend to be more positive and less negative than younger adults, but social contact and working memory often decrease with age, both of which might limit older adults' social functioning. In the current study of younger and older adults, these socially facilitative vs. socially debilitative changes were found to underlie stasis in social satisfaction. These findings show that the lack of an overall effect for age can mask competing changes in social functioning in late adulthood, as the sources of social satisfaction might change even if the outcome does not. 相似文献

This study examined differences between healthy children (n = 35) and those with spina bifida myelomeningocele (SBM; n = 42) on the Behavior Rating Inventory of Executive Function (BRIEF), a measure of executive function behaviors. It also examined whether aspects of biological risk associated with SBM and reserve factors within the family could account for variability in BRIEF scores for children and adolescents with SBM. Patients in the SBM group exhibited more problems than both published norms and a local comparison group of healthy children in metacognition but not behavior regulation. Behavior regulation problems in children with SBM were predicted by parent psychological distress. More shunt-related surgeries and history of seizures predicted poorer metacognitive abilities. 相似文献

The aim of the present study was to evaluate the occurrence of fear sensitization in rats previously treated with an inhibitor of the NO syntheses and submitted to Trial1/Trial2 plus-maze (PM) procedure. Male Wistar rats received a systemic treatment with N(omega)-nitro-L-Arginine-methyl ester (L-NAME; 5, 10 or 50 mg kg(-1)) and were submitted to PM Trial1. In the following day the animals were re-exposed to the PM with no drug administration (Trial2). Some standards spatial-temporal measures, such as the percentage of entries (% Open arm entries) and time spent (% Open arm time) in the open arms and risk assessment frequency were recorded and used to estimate the animal level of fear sensitization in PM Trial2. The results showed that animals receiving L-NAME (50 mg kg(-1)) displayed increased % Open arm entries and % Open arm time in Trial2 in relation to the group receiving 0.9% saline, which is compatible with impaired fear/anxiety acquisition during Trial1/Trial2 PM procedure. In addition, rats treated with L-NAME (50 mg kg(-1)) exhibited low level of risk assessment in Trial2 in relation to the group treated with 0.9% saline, which indicates low level of fear/anxiety during PM re-exposure. The number of entries into the enclosed arms was not changed by any L-NAME treatment, which suggests no bias of the drug treatments on animal locomotor activity. The data suggest that NO synthesis may mediate the fear sensitization process in the PM. 相似文献

We examined links between mothers' parenting and children's relational bullying and overt bullying in a sample of children attending a Head Start program. Mothers completed surveys and face-to-face interviews. Head Start teachers completed assessments on children. Results indicated that a small percentage of children in the sample was rated by teachers as engaging in relational bullying “frequently to almost always,” and slightly over half of the sample was rated by teachers as engaging in relational bullying “occasionally to about half of the time.” Similar results were found for the frequency with which children engaged in overt physical bullying. Regarding mothers' parenting, maternal empathy was most strongly correlated with both children's relational bullying and overt physical bullying. In addition, mothers' inappropriate developmental expectations for children and mothers' need to exert power over children rather than grant them independence were related to children's relational bullying. A composite variable for mothering predicted 11% of the variance in children's relational bullying. No gender differences were found for children's relational bullying and children's overt bullying. 相似文献
