Is it possible that voles have a sense of number? To address this question, we determined whether voles discriminate between two different scent-marking individuals and identify the individual whose scent marks was on top more often than the other individual. We tested whether voles show a preference for the individual whose scent marks was on top most often. If so, the simplest explanation was that voles can make a relative size judgement—such as distinguishing an area containing more of one individual’s over-marks as compared to less of another individual’s over-marks. We found that voles respond preferentially to the donor that provided a greater number of over-marks as compared to the donor that provided a lesser number of over-marks. Thus, we concluded that voles might display the capacity for relative numerousness. Interestingly, female voles were better able than male voles to distinguish between small differences in the relative number of over-marks by the two scent donors. 相似文献

Social identity complexity refers to the way in which individuals subjectively represent the relationships among their multiple ingroup memberships. More specifically, individuals with low social identity complexity see their ingroups as highly overlapping and convergent, whereas those with high complexity see their different ingroups as distinct and cross-cutting membership groups. The present study tested the hypothesis that perceived overlap among ingroup memberships would be negatively related to ingroup inclusiveness and tolerance for outgroups, such that individuals with high overlap (low complexity) would be less tolerant and accepting of outgroups in general than those with low overlap (high complexity). Results from a telephone interview survey of adult residents of the state of Ohio supported this hypothesis. Individual differences in complexity of perception of their national, religious, occupational, political, and recreational social identities were systematically related to their attitudes toward ethnic outgroups and diversity. 相似文献

Two studies examined narcissism and behavior in a commons dilemma. Study 1 used a four-person, laboratory-based task and Study 2 used a dyadic task. Participants were told that they represented one of four (Study 1) or two (Study 2) forestry companies and then were asked to harvest timber from a renewable forest. Narcissism was found to be positively related to acquisitive goals and harvesting more timber in the initial round. The more narcissists harvesting in the competitive group of four (Study 1) or dyad (Study 2), the less timber was harvested overall and the more rapidly the forest was depleted. Within competitive groups and dyads, however, narcissists harvested more than the nonnarcissists competing with them. In all, narcissism provided a benefit to the self, but at a long-term cost to other individuals and to the commons. 相似文献

The effects of socioeconomic status (SES) on health are well documented in adulthood, but far less is known about its effects in childhood. The authors reviewed the literature and found support for a childhood SES effect, whereby each decrease in SES was associated with an increased health risk. The authors explored how this relationship changed as children underwent normal developmental changes and proposed 3 models to describe the temporal patterns. The authors found that a model's capacity to explain SES-health relationships varied across health outcomes. Childhood injury showed stronger relationships with SES at younger ages, whereas smoking showed stronger relationships with SES in adolescence. Finally, the authors proposed a developmental approach to exploring mechanisms that link SES and child health. 相似文献

Event-related potentials (ERPs) were used to investigate whether the processing of subject-verb dependencies is influenced by (1) the linear distance between the subject and the verb and (2) the presence of an intervening noun phrase with interfering number features. Linear distance did not affect integration and diagnosis or revision processes at the verb, as indexed by early negative and P600 components. This is in accordance with hierarchy-based models of reanalysis, but is problematic for distance-based integration models. However, tracking of the subject features is affected by linear factors: more judgment errors were made in the long compared to the short condition. Furthermore, the presence of a plural object between the singular subject and the verb led to more judgment errors, and an enhanced positivity around 250 ms for the grammatical verbs. This suggests that linear factors affect feature tracking, but not integration processes following feature retrieval or repair processes following the detection of a mismatch. 相似文献

Syntactic comprehension is a fundamental aspect of human language, and has distinct properties from other aspects of language (e.g. semantics). In this article, we aim to identify if there is a specific locus of syntax in the brain by reviewing imaging studies on syntactic processing. We conclude that results from neuroimaging support evidence from neuropsychology that syntactic processing does not recruit one specific area. Instead a network of areas including Broca's area and anterior, middle and superior areas of the temporal lobes is involved. However, none of these areas appears to be syntax specific. 相似文献

This study examined the potentially compounding effect of language minority (LM) status on problem behaviors among urban second and third grade-level poor readers. Univariate analyses showed that a disproportionate percentage of both LM and English monolingual (L1) poor readers already displayed clinically significant levels of anxiety, social problems, and oppositional behaviors in the classroom. Analyses of variance, however, demonstrated that LM status was not an additive risk factor for reading difficulties, behavior problems, or lowered self-concept in this sample. No differences were observed between LM and L1 students on a wide range of reading measures, on their teachers’ ratings of internalizing and externalizing problem behaviors in the classroom, or on self-ratings of self-efficacy and social competence. Implications for intervention for all urban students with reading difficulties are discussed. 相似文献

We show that counting downward while performing a task shortens the perceived duration of the task compared to counting upward. People perceive that less time has elapsed when they were counting downward versus upward while using a product (Studies 1 and 3) or watching geometrical shapes (Study 2). The counting direction effect is obtained using both prospective and retrospective time judgments (Study 3), but only when the count range begins with the number “1” (Study 2). Furthermore, the counting direction affects peoples' attitude toward the product, their likelihood of using it again, and their purchase intentions. We test several plausible accounts for the counting direction effect, including task difficulty, numerical anchoring, and arousal. We find preliminary evidence that downward counting feels shorter because it is more arousing than upward counting. 相似文献

This paper attempts to draw attention to the difference between the states of mind and inner worlds of neurotic, borderline and psychopathic patients, with reference to different types of destructiveness: anger in the neurotic patient; desperate vengeful hatred in the borderline paranoid; and a cold addiction to violence in the psychopath. Discussion focuses on technical issues and the need to meet the psychopathic patient where he really is, in the inner bleak emotional cemetery he may be inhabiting. Although most patients refuse to stay put in the neat schematic categories outlined, they do seem to appreciate and to need the therapist's recognition of the specific quality of these vastly different states of mind. 相似文献
