Aging and maintaining intentions over delays: do it or lose it   总被引:3,自引:0,他引:3  
When execution of retrieved intentions must be briefly delayed, older adults display deficits in performing those intentions (G. O. Einstein, M. A. McDaniel, M. Manzi, B. Cochran, & M. Baker, 2000). This initial finding was extended by showing age-related deficits with 5-s unfilled delays, with instructions to rehearse during the delay, and with divided attention during initial retrieval of the intention. Performance increased with a break at the end of the delay period, such that when combined with full attention (during retrieval), older adults' performance approached that of younger adults. These results suggest that age compromises maintenance of information in awareness. Consequently, when forced to delay execution of retrieved intentions, older adults may rely more on plan reformulation and subsequent retrieval of the intention from long-term memory at the end of the delay.  相似文献

We examined the influence of newly acquired information on children's memory and general representation of a personally experienced event. Thirty-five children between the ages of 5 and 7 years participated in the novel event (Visiting the Pirate). The day before participating, children were: (1) provided with new information specific to the up-coming event; (2) engaged in a discussion generally related to the event topic based on existing knowledge; or (3) discussed an unrelated topic. Advance information specific to the event led to better recall and, in particular, to better integration of the experience into a general event representation both soon after the event and at a follow-up interview 4 months later, whereas general discussion of the topic without the event specific information neither enhanced memory reports nor facilitated the integration of event information. Providing information in advance can have significant effects on memory and knowledge acquisition although many variables, including those relating to the specific content of the information, will affect this relation.  相似文献

Variations in the serotonin transporter gene (5HTTLPR) and biased processing of face-emotion displays both have been implicated in the transmission of depression risk, but little is known about developmental influences on these relationships. Within a community sample of adolescents, we examine whether 5HTTLPR genotype moderates the link between maternal depressive history and errors in face-emotion labeling. When controlling for current levels of depression and anxiety among youth, a two-way interaction between maternal depressive history and 5HTTLPR genotype was detected. Specifically, adolescents whose mothers reported a depressive history and who had a low expressing genotype made more errors in classifying emotional faces when compared with adolescents with an intermediate or high expressing genotype, with or without maternal depression history. These findings highlight the complex manner in which maternal depression and genetic risk may interact to predict individual differences in social information processing.  相似文献

This study was a follow up investigation of Brawer et al.’s (Prof Psychol Res Pr 33(2):203–206, 2002) survey of education and training of clinical psychologists in religion/spirituality. Directors of clinical training were surveyed to determine whether changes had occurred in the coverage of religion and spirituality through course work, research, supervision, and in the systematic coverage of the content area. Results indicated an increased coverage in the areas of supervision, dedicated courses, inclusion as part of another course, and research. There was no increase in systematic coverage, but significantly more programs provided at least some coverage. The current study also assesses other areas of incorporation as well as directors’ opinions regarding the importance of religion/spirituality in the field of psychology.  相似文献

Two studies (one field, one experimental) found that the more accurately individuals evaluated their performance, the better they performed on a subsequent task. The first study also found that the more individuals overestimated their previous performance, the lower was their performance on the next task. In contrast, the evaluation accuracy of the underestimators was unrelated to their subsequent performance. The second study found that when participants received feedback from an external authority, the effect of the inaccuracy of self-performance evaluation on subsequent performance was reduced. The results of the 2 studies are explained in motivational and cognitive terms.  相似文献

Previous binocular rivalry studies with younger adults have shown that emotional stimuli dominate perception over neutral stimuli. Here we investigated the effects of age on patterns of emotional dominance during binocular rivalry. Participants performed a face/house rivalry task where the emotion of the face (happy, angry, neutral) and orientation (upright, inverted) of the face and house stimuli were varied systematically. Age differences were found with younger adults showing a general emotionality effect (happy and angry faces were more dominant than neutral faces) and older adults showing inhibition of anger (neutral faces were more dominant than angry faces) and positivity effects (happy faces were more dominant than both angry and neutral faces). Age differences in dominance patterns were reflected by slower rivalry rates for both happy and angry compared to neutral face/house pairs in younger adults, and slower rivalry rates for happy compared to both angry and neutral face/house pairs in older adults. Importantly, these patterns of emotional dominance and slower rivalry rates for emotional-face/house pairs disappeared when the stimuli were inverted. This suggests that emotional valence, and not low-level image features, were responsible for the emotional bias in both age groups. Given that binocular rivalry has a limited role for voluntary control, the findings imply that anger suppression and positivity effects in older adults may extend to more automatic tasks.  相似文献

Although research on the reasons for engaging in nonsuicidal self-injury (NSSI) has increased dramatically in the last few years, there are still many aspects of this pernicious behavior that are not well understood. The purpose of this study was to address these gaps in the literature, with a particular focus on investigating whether NSSI (a) regulates affective valence in addition to affective arousal and (b) serves a cognitive regulation function in addition to an affect regulation function. To elucidate these issues, the present study utilized a sample of 112 participants (33 controls, 39 no pain controls, 16 NSSI individuals, and 24 controls matching the affect dysregulation levels of the NSSI group), employed psychophysiological measures of affective valence (startle-alone reactivity) and quality of information processing (prepulse inhibition), and used experimental methods involving an NSSI-proxy to model the NSSI process. Results largely were consistent with predictions, supporting the hypotheses that NSSI serves to regulate cognitive processing and affective valence. On this latter point, however, the control groups also showed a decrease in negative affective valence after the NSSI-proxy. This unexpected finding is consistent with the hypothesis that opponent processes may contribute to the development of self-injurious behaviors (Joiner, 2005). Overall, the present study represents an important extension of previous laboratory NSSI studies and provides a fertile foundation for future studies aimed at understanding why people engage in NSSI.  相似文献

The reported study measured the ratio between aperture‐width and hip‐width that marked the critical transition from frontal walking to body rotation for male and female participants. Half of the participants of each sex wore form‐fitting lycra clothes and half loose‐fitting jogging suits. Participants wearing the form‐fitting clothing reported heightened body awareness relative to those wearing the loose‐fitting clothing. For male participants this difference was reflected in a smaller aperture‐to‐hip ratio in the form‐fitting than loose‐fitting clothing condition. That is, males walked frontally through smaller apertures when wearing form‐fitting than when wearing loose‐fitting clothing. For females there was no difference in walking action as a function of clothing style. Results are discussed in terms of the perception of action opportunities in the environment, the influence of body awareness on such perception and sex differences.

The present research examined the extent to which interpersonal concerns about rejection based on appearance, or Appearance-based Rejection Sensitivity (Appearance-RS), serves as an indicator of risk for excessive body image concerns. Extending previous research, we examined the association between Appearance-RS and symptoms of body dysmorphic disorder (BDD) and cosmetic surgery attitudes among 106 British university students. Consistent with predictions, Appearance-RS uniquely predicted greater degree of BDD symptoms after controlling for other known predictor variables. Also, as expected, Appearance-RS uniquely predicted acceptance of cosmetic surgery for both intrapersonal and social reasons and greater consideration of having cosmetic surgery in the future. These findings highlight the importance of assessing individuals’ sensitivity to rejection from others based on their physical appearance in investigations of excessive body image concerns.  相似文献

Integration of simultaneous auditory and visual information about an event can enhance our ability to detect that event. This is particularly evident in the perception of speech, where the articulatory gestures of the speaker's lips and face can significantly improve the listener's detection and identification of the message, especially when that message is presented in a noisy background. Speech is a particularly important example of multisensory integration because of its behavioural relevance to humans and also because brain regions have been identified that appear to be specifically tuned for auditory speech and lip gestures. Previous research has suggested that speech stimuli may have an advantage over other types of auditory stimuli in terms of audio-visual integration. Here, we used a modified adaptive psychophysical staircase approach to compare the influence of congruent visual stimuli (brief movie clips) on the detection of noise-masked auditory speech and non-speech stimuli. We found that congruent visual stimuli significantly improved detection of an auditory stimulus relative to incongruent visual stimuli. This effect, however, was equally apparent for speech and non-speech stimuli. The findings suggest that speech stimuli are not specifically advantaged by audio-visual integration for detection at threshold when compared with other naturalistic sounds.  相似文献
