Research on adult concepts indicates that category structure varies by domain; adults view membership in animal categories
as absolute but membership in artifact categories as graded. In this study, we examined domain differences in beliefs about
category boundaries among young children (5-year-olds). The results indicated that young children, like adults, were less
likely to endorse graded category membership for animal than for artifact categories. These domain differences could not be
attributed to domain differences in typicality. Implications for conceptual development and for models of domain specificity
in adult cognition are discussed. 相似文献

Through two studies with diverse samples, we tested a conceptual model of the relationships between organizational and career factors and older workers' intention to remain with their organization. Perceived organizational support mediated the relationship between training and development practices, hierarchical, and job content plateauing and intention to remain. Career satisfaction mediated the relationship between perceived organizational support, job content plateauing, and intention to remain. We conclude that implementing training and development practices targeting older workers and tailored to their needs and providing interesting and challenging job assignments are important to perceptions of organizational support and career satisfaction and ultimately to the retention of older workers. 相似文献

Experiments were conducted to investigate which sensory cues are used by brown capuchins (Cebus apella) in embedded invertebrate foraging. The importance of visual, olfactory, and acoustic cues in such foraging was determined by presenting subjects with a stimulus log modified to block out given sensory cues. Experiment 1 was designed to investigate whether subjects could locate an invertebrate embedded in wood when only visual, acoustic, or olfactory information was available. Experiments 2 and 3 were designed to investigate extractive foraging behavior when two sensory cues were provided. It was hypothesized that the combination of visual and acoustic information would be necessary for subjects to successfully locate embedded invertebrates. Results indicated that subjects' performance was most successful when both visual and acoustic information was available. 相似文献

The Wisconsin Personality Disorders Inventory (WISPI-IV; Klein & Benjamin, 1996) is the latest version of a self-report measure of DSM-IV personality disorders (PDs) derived from an interpersonal perspective. When categorical diagnoses derived from the WISPI-IV were compared with independent SCID-II diagnoses, the majority of the kappas were poor (>.40). However, all but one of the effect sizes for the differences in WISPI-IV means between groups with and without SCID-II diagnoses were large (>.80). When SCID-II and WISPI-IV dimensional scores were considered, the average r between profiles was .61 (median = .58) and correlations between corresponding PD scales (mean diagonal r = .48; mean off-diagonal r = .18) indicated good convergent and discriminant validity for five of the WISPI-IV scales. These results add to the cumulating evidence suggesting greater reliability and validity of dimensional over categorical scores for PDs. Researchers and clinicians interested in having an efficient method of assessing PDs may consider using a dimensional approach such as the WISPI-IV as an alternative to diagnostic interview. 相似文献

Electrophysiological responses to errors and feedback in the process of action regulation 总被引:18,自引:0,他引:18
The anterior cingulate cortex (ACC) is believed to be involved in the executive control of actions, such as in monitoring conflicting response demands, detecting errors, and evaluating the emotional significance of events. In this study, participants performed a task in which evaluative feedback was delayed, so that it was irrelevant to immediate response control but retained its emotional value as a performance indicator. We found that a medial frontal feedback-related negativity similar to the error-related negativity (ERN) tracked affective response to the feedback and predicted subsequent performance. Source analysis of the feedback-related negativity and ERN revealed a common dorsomedial ACC source and a rostromedial ACC source specific to the ERN. The oscillatory nature of these sources provides further evidence that the ERN reflects ongoing theta activity generated in the mediofrontal regions. These results suggest that action regulation by the cingulate gyrus may require the entrainment of multiple structures of the Papez corticolimbic circuit. 相似文献

This study examined the role of self-reported attentional control in regulating attentional biases related to trait anxiety. Simple detection targets were preceded by cues labeling potential target locations as threatening (likely to result in negative feedback) or safe (likely to result in positive feedback). Trait anxious participants showed an early attentional bias favoring the threatening location 250 ms after the cue and a late bias favoring the safe location 500 ms after the cue. The anxiety-related threat bias was moderated by attentional control at the 500-ms delay: Anxious participants with poor attentional control still showed the threat bias, whereas those with good control were better able to shift from the threatening location. Thus, skilled control of voluntary attention may allow anxious persons to limit the impact of threatening information. 相似文献

The present study aimed to investigate whether perfectionism mediates the association between obsessive–compulsive (OC) and eating disorder (ED) symptoms. Analyses were conducted using data collected among a national sample of eating disordered women diagnosed with BN or a subclinical variant of BN (N = 204). Each participant completed a series of self-report inventories on perfectionism, as well as OC, ED, and depressive symptoms. Higher ED symptoms were significantly associated with greater levels of perfectionism (p < .01) and OC symptoms (p < .05). As hypothesized, perfectionism significantly mediated the relationship between ED and OC symptoms, controlling for depression. Findings indicate that perfectionism may be considered a shared etiological or phenomenological factor in ED and OC symptoms. 相似文献
