ABSTRACT Standard measures of phonemic and semantic fluency, as well as fluency measures that impose additional demands upon set-switching were administered to younger and older adults. No age effect was found for total output on semantic fluency, while older participants generated significantly more responses relative to their younger counterparts on the phonemic measure. However, older adults made significantly more perseverative errors on both these measures. For tests of alternating fluency, only where participants were required to switch between two semantic dimensions, was an age deficit observed. Although the correlation between phonemic repetitions and age remained significant when performance on the Digit Symbol Test or a measure of fluid intelligence was partialled out, age effects for semantic repetitions and semantic alternating fluency were substantially reduced. The age benefit for number of correct responses upon phonemic fluency was significantly attenuated when a measure of crystallized intelligence was entered as a control variable. The theoretical and practical implications of these results are discussed. 相似文献

This study examined the helping behavior of participants with high (High-P; 15 males, 13 females) and low (Low-P; 14 males, 16 females) psychopathic traits without their awareness. In the first of three tests, we found Low-P participants offered more help to an apparently lost female confederate than High-P participants. In the second test, High-P compared to Low-P males offered more help to an “injured” female experimenter, the reverse was true for females. In the third test, High-P compared to Low-P females offered more help to a female confederate who had apparently dropped papers they were carrying; whereas the reverse was true for males. Our preliminary findings indicate that context, gender and psychopathic traits interact and impact helping behavior. 相似文献

The purpose of this study was to consider the role of remembering in the development of the ability to plan and carry out sequences of dependent actions. A task calling for sequencing of choices was administered to 46 four-year-olds, 30 seven-year-olds, and 30 10-year-olds. Each child participated in both a remembering (control) condition and a facilitation-of-remembering condition. Performance was better in the facilitation-of-remembering condition than in the remembering (control) condition, but only for four-year-olds (p < .01), indicating that the failure to remember alternatives, rather than a lack of other cognitive abilities, may be a major obstacle in preschoolers' development of planning abilities. An apparent regression in performance of seven-year-olds (p < .01) is interpreted as an inappropriate application of transitional operative understanding of dependent events to situations involving only chance sequences. 相似文献

Educators have proposed that admired behavior by media characters evokes audience emulation if subsequent personal reflection results in audience members realizing that they want to and are able to behave in a similar manner. Two experiments investigated this. In Study 1, exposure to prosocial media models increased altruistic inclinations among teenagers only if they were also instructed to reflect on the personal significance of what they had seen. In Study 2, medical students exposed to prosocial media models had higher empathic and altruistic intentions if they reflected on the personal rather than the professional significance of what they had seen. Personal inspiration and recognition of enactment possibilities seemed key determinants of emulation. 相似文献

The hypothesis that lonely children show hypervigilance for social threat was examined in a series of three studies that employed different methods including advanced eye-tracking technology. Hypervigilance for social threat was operationalized as hostility to ambiguously motivated social exclusion in a variation of the hostile attribution paradigm (Study 1), scores on the Children’s Rejection-Sensitivity Questionnaire (Study 2), and visual attention to socially rejecting stimuli (Study 3). The participants were 185 children (11 years-7 months to 12 years-6 months), 248 children (9 years-4 months to 11 years-8 months) and 140 children (8 years-10 months to 12 years-10 months) in the three studies, respectively. Regression analyses showed that, with depressive symptoms covaried, there were quadratic relations between loneliness and these different measures of hypervigilance to social threat. As hypothesized, only children in the upper range of loneliness demonstrated elevated hostility to ambiguously motivated social exclusion, higher scores on the rejection sensitivity questionnaire, and disengagement difficulties when viewing socially rejecting stimuli. We found that very lonely children are hypersensitive to social threat. 相似文献

The objective of this study was to examine the effectiveness of a 12 week weight loss intervention within a commercial fitness centre on body weight, moderate to vigorous physical activity (MVPA), dietary intake, and behavioural regulations for exercise and healthy eating. Using a quasi-experimental design, the intervention group received weekly coaching sessions and bi-weekly seminars designed to increase MVPA and improve dietary intake. Outcome variables were assessed at three time points over a six month period. Results showed a significant interaction for body weight (p = .04) and dietary changes (p < .05) following the weight loss challenge but were not maintained across the six month period. Changes in behavioural regulations favoured the intervention condition. Results imply that a 12 week weight loss challenge within a commercial fitness centre may be effective at prompting short-term weight loss and support the internalization of behavioural regulations specific to healthy eating and exercise. 相似文献

Current models of visual perception suggest that, during scene categorization, low spatial frequencies (LSF) are rapidly processed and activate plausible interpretations of visual input. This coarse analysis would be used to guide subsequent processing of high spatial frequencies (HSF). The present study aimed to further examine how information from LSF and HSF interact and influence each other during scene categorization. In a first experimental session, participants had to categorize LSF and HSF filtered scenes belonging to two different semantic categories (artificial vs. natural). In a second experimental session, we used hybrid scenes as stimuli made by combining LSF and HSF from two different scenes which were semantically similar or dissimilar. Half of the participants categorized LSF scenes in hybrids, and the other half categorized HSF scenes in hybrids. Stimuli were presented for 30 or 100?ms. Session 1 results showed better performance for LSF than HSF scene categorization. Session 2 scene categorization was faster when participants attended and categorized LSF than HSF scene in hybrids. The semantic interference of a semantically dissimilar HSF scene on LSF scene categorization was greater than the semantic interference of a semantically dissimilar LSF scene on HSF scene categorization, irrespective of exposure duration. These results suggest a LSF advantage for scene categorization, and highlight the prominent role of HSF information when there is uncertainty about the visual stimulus, in order to disentangle between alternative interpretations. 相似文献

Older adults often perform poorly on Theory of Mind (ToM) tests that require understanding of others’ beliefs and intentions. The course and specificity of age changes in belief reasoning across the adult lifespan is unclear, as is the cause of the age effects. Cognitive and neuropsychological models predict that two types of processing might influence age differences in belief reasoning: executive functioning and social cue detection. In the current study we assessed 129 adults aged between 18 and 86 on novel measures of ToM (video clips and verbal vignettes), which manipulated whether true or false belief reasoning was required. On both video and verbal tasks, older adults (aged 65–88) had specific impairments in false belief reasoning, but showed no such problem in performing true belief tasks. Middle-aged adults (aged 40–64) generally performed as well as the younger adults (aged 18–39). Difficulties in updating information in working memory (but not inhibitory problems) partially mediated the age differences in false belief reasoning. Also, the ability to decode biological motion, indexing social cue detection, partially mediated age-related variance in the ability to interpret false beliefs. These results indicate that age differences in decoding social cues and updating information in memory may be important influences on the specific problems encountered when reasoning about false beliefs in old age. 相似文献
