Schoolchildren, aged 16 years showed poorer incidental learning for nouns if the orienting task was one of finding rhymes for the items compared to assigning each word to a semantic category. On a recognition task including homophone and synonym foils, rhyming subjects made significantly more phonemic errors, whereas categorizing subjects produced a significantly greater number of semantic confusions. Subjects instructed to construct images for each of the nouns showed a performance pattern similar to the categorizing group. The results are interpreted in terms of Herriot's (1974) view that different levels of processing are associated with the coding of different clusters of stimulus attributes.  相似文献

College students were asked if they would be willing to serve as student contacts for high school students applying for admission to the university who wanted more information about student life. Students volunteered to spend more time helping a female applicant if she wanted to become a librarian than if she wanted to become an engineer, while they volunteered to spend more time helping a male applicant if he wanted to become an engineer than if he wanted to become a librarian. Results were the same when the dependent measure was the amount of time volunteered for interviews, for telephone conversations, and for letterwriting, indicating that the amount of personal contact required did not influence subjects' preference to help those whose career aspirations were sex-role appropriate more than those whose career goals were sex-role inappropriate.  相似文献

Face aftereffects can provide information on how faces are stored by the human visual system (eg Leopold et al, 2001 Nature Neuroscience 4 89-94), but few studies have used robustly represented (highly familiar) faces. In this study we investigated the influence of facial familiarity on adaptation effects. Participants were adapted to a series of distorted faces (their own face, a famous face, or an unfamiliar face). In experiment 1, figural aftereffects were significantly smaller when participants were adapted to their own face than when they were adapted to the other faces (ie their own face appeared significantly less distorted than a famous or unfamiliar face). Experiment 2 showed that this 'own-face' effect did not occur when the same faces were used as adaptation stimuli for participants who were unfamiliar with them. Experiment 3 replicated experiment 1, but included a pre-adaptation baseline. The results highlight the importance of considering facial familiarity when conducting research on face aftereffects.  相似文献

These experiments examined the effects of the NMDA-receptor (NMDAr) antagonist MK801 on reacquisition and re-extinction of a conditioned fear that had been previously extinguished before injection of fibroblast growth factor-2 (FGF2) or vehicle. Recent findings have shown that relearning and re-extinction, unlike initial learning and extinction, do not depend on NMDAr activation. Three experiments demonstrated that FGF2 prevents the switch from NMDAr-dependent to NMDAr-independent reacquisition and re-extinction, suggesting that FGF2 may lead to the partial erasure of the original fear memory. These findings add to a growing body of work suggesting that FGF2 may be a novel pharmacological enhancer of exposure therapy for humans with anxiety disorders.  相似文献

Configural processing is important for face recognition, but its role in other types of face processing is unclear. In the present study, participants made judgments of head tilt for faces in which the vertical position of the internal facial region was varied. We found a highly reliable relationship between inner-face position and perceived head tilt. We also found that changes in inner-face position affected the perceived dimensions of an individual unchanged facial feature: compared to control faces, nearly two-thirds of faces in which the features had been moved down were judged to have a longer nose. This finding suggests an early integration of configural and featural processing to create a stable holistic percept of the face. The demonstration of holistic processing at a basic perceptual level (as opposed to during face recognition) is important as it constrains possible models of the relationships between featural and configural processing.  相似文献

Non-suicidal self-injury (NSSI) occurs in approximately 10 % of adolescents. To establish effective prevention and intervention initiatives, it is important to understand onset, maintenance and cessation of NSSI. We explored whether the relationships between interpersonal factors (i.e. attachment, social support) and NSSI were mediated by intrapersonal factors (i.e. emotion regulation, self-esteem, self-efficacy). Participants were 1973 students (1414 female and 559 male) aged between 12 and 18 years (M?=?13.89, SD?=?0.97) recruited from 40 Australian high schools. Participants completed a questionnaire at two time-points with a 12-month interval. At baseline, 8.3 % of adolescents engaged in NSSI, increasing to 11.9 % at follow-up. Family support was most salient in onset, maintenance and cessation of NSSI. Attachment anxiety was related to NSSI onset. Of the intrapersonal variables, self-esteem and self-efficacy were significant in predicting onset of NSSI. Self-esteem, self-efficacy and cognitive reappraisal mediated the relationship between attachment anxiety and NSSI onset. A combination of interpersonal and intrapersonal variables contributes to the onset, maintenance and cessation of NSSI in adolescence. Perceived family support appears to be an important safeguard against NSSI. Strategies targeting family functioning and teaching cognitive reappraisal techniques to adolescents may reduce the number engaging in NSSI.  相似文献

A first step toward understanding the etiology of personality is to investigate the relative impact of genetic and environmental factors using twin and adoption designs. Twin studies of infants and young children indicate substantial genetic influence for parental ratings of temperament in the preschool years. Adoption studies, however, have not previously been reported during the early years of life. We present parent-offspring comparisons for temperament (emotionality, activity, sociability, and impulsivity) for adopted and nonadopted children yearly from 1 to 7 years of age and their biological, adoptive, and nonadoptive parents. Also presented are correlations for adoptive and nonadoptive siblings when each child was 1, 2, 3, and 4 years of age. In contrast with twin results, little evidence is found for genetic influence. The average correlation between biological parents and their adopted-away children for data averaged over the 7 years is only .03. Similarly, the average parent-offspring correlation in nonadoptive families (.08) is no greater than in adoptive families (.12). Results for nonadoptive and adoptive siblings also indicate little genetic influence. The difference between the twin and adoption results may be due to environmental effects or to nonadditive genetic variance.  相似文献
