Is task interference in event-based prospective memory dependent on cue presentation? 总被引:1,自引:0,他引:1
Whether having an intention produces a performance cost to ongoing activities (task interference) is central to theoretical claims regarding the mechanisms underlying cue detection in event-based prospective memory. Recent evidence suggests that task interference primarily reflects an attention allocation policy stored in memory when intentions are encoded. The present study examined whether these policies can change with ongoing task experience. In Experiment 1, task interference was more greatly reduced when expected cues were not presented than when they were. Experiment 2 replicated this effect when the importance of the prospective memory task was emphasized. In Experiment 3, task interference decreased with time, and this decrease was greater when expected cues were not presented than when they were. Cue presentation is crucial to maintenance of attention allocation policies established by task instructions. This is the first article to demonstrate changes in task interference with ongoing task experience without forewarning individuals of the relevance of upcoming ongoing task trials to intentions. 相似文献

Prominent lifespan theories posit that older adults are motivated to engage in emotion-regulation more frequently than younger adults. The present study follows from such theories and makes a novel prediction hitherto unexamined in the aging–emotion literature. Based on the idea that older adults more frequently regulate their emotions, it was predicted that traits, reflective of temperament or habit, would be less predictive of emotions among older adults (N = 60; M age = 74.9 years) than younger adults (N = 44; M age = 19.5 years). This hypothesis was confirmed across four of the Big 5 traits and, consistent with predictions, the moderating effects of age were particularly strong for negative emotions. The discussion focuses on the implications of the present findings for understanding age differences in personality, emotion, and emotion-regulation. 相似文献

We investigated the associations between Boston naming and the animal fluency tests and cortical atrophy in 19 probable AD and 5 multiple domain amnestic mild cognitive impairment patients who later converted to AD. We applied a surface-based computational anatomy technique to MRI scans of the brain and then used linear regression models to detect associations between animal fluency and Boston Naming Test (BNT) performance and cortical atrophy. The global permutation-corrected significance for the maps associating BNT performance with cortical atrophy was p=.0124 for the left and p=.0196 for the right hemisphere and for the animal fluency maps p=.055 for the left and p=.073 for the right hemisphere. The degree of language impairment correlated with cortical atrophy in the left temporal and parietal lobes (BA 20, 21, 37, 39, 40, and 7), bilateral frontal lobes (BA 8, 9, and 44) and the right temporal pole (BA 38). Using a novel 3D mapping technique, we demonstrated that in AD language abilities are strongly influenced by the integrity of the perisylvian cortical regions. 相似文献

Participants' eye movements were recorded as they read sentences with words containing transposed adjacent letters. Transpositions were either external (e.g., problme, rpoblem) or internal (e.g., porblem, probelm) and at either the beginning (e.g., rpoblem, porblem) or end (e.g., problme, probelm) of words. The results showed disruption for words with transposed letters compared to the normal baseline condition, and the greatest disruption was observed for word-initial transpositions. In Experiment 1, transpositions within low frequency words led to longer reading times than when letters were transposed within high frequency words. Experiment 2 demonstrated that the position of word-initial letters is most critical even when parafoveal preview of words to the right of fixation is unavailable. The findings have important implications for the roles of different letter positions in word recognition and the effects of parafoveal preview on word recognition processes. 相似文献

This study examined the role of 2 central aspects of family life--income and social support--in predicting concurrent happiness and change in happiness among 274 married adults across a 10-year period. The authors used hierarchical linear modeling to investigate the relationship between family income and happiness. Income had a small, positive impact on happiness, which diminished as income increased. In contrast, family social support, measured by 3 subscales, Cohesion, Expressiveness, and Conflict, showed a substantial, positive association with concurrent happiness, even after controlling for income. Furthermore, family income moderated the association between family social support and concurrent happiness; family social support was more strongly associated with happiness when family income was low than when family income was high. In addition, change in family social support was positively related to change in happiness, whereas change in family income was unrelated to change in happiness. These findings suggest that happiness can change and underscore the importance of exploring more deeply the role that family relationships play in facilitating such change. 相似文献

Depression and anxiety often involve high levels of trait anger and disturbances in anger expression. Reported anger experience and outward anger expression have recently been associated with left-biased asymmetry of frontal cortical activity, assumed to reflect approach motivation. However, different styles of anger expression could presumably involve different brain mechanisms and/or interact with psychopathology to produce various patterns of brain asymmetry. The present study explored these issues by comparing resting regional electroencephalographic activity in participants high in trait anger who differed in anger expression style (high anger-in, high anger-out, both) and participants low in trait anger, with depression and anxiety systematically assessed. Trait anger, not anger-in or anger-out, predicted left-biased asymmetry at medial frontal EEG sites. The anger-in group reported higher levels of anxious apprehension than did the anger-out group. Furthermore, anxious apprehension moderated the relationship between trait anger, anger-in, and asymmetry in favor of the left hemisphere. Results suggest that motivational direction is not always the driving force behind the relationship of anger and left frontal asymmetry. Findings also support a distinction between anxious apprehension and anxious arousal. 相似文献

Two studies examined the association between depressive symptoms and romantic involvement in adolescence and tested the hypothesis that romantic involvement is associated more strongly with symptoms among adolescents who have a more preoccupied style of relating, compared to adolescents who have a less preoccupied style of relating. Study 1 (N = 96 early adolescent females) examined concurrent associations and Study 2 (N = 80 late adolescent males and females) examined longitudinal associations. In both age groups, romantic involvement was associated with greater depressive symptoms and this was most true among adolescents with a preoccupied style of relating. Implications for models of depression and adolescent romantic functioning are discussed. 相似文献

This study develops a video playback methodology: children aged five to eight years viewed taped play fighting and real fighting bouts in which they were both participants and nonparticipants. Views of participants were also compared for immediate and delayed viewing. The methodology examines the criteria used to distinguish play fighting and real fighting; views concerning the characteristics of such episodes; and the motivations involved. The methodology was found to be feasible at this age; and useful in terms of differing views of participants and nonparticipants. There was evidence for increased insight from participants, who used more criteria to make their judgments, and more informative criteria such as knowledge of the rules of a game being played. Participant knowledge was most evident at the immediate viewings, but was partially retained one week later. Participants (more than nonparticipants) mostly described play fighting as friendly, and not involving hurt or showing off. The methodology could usefully be applied to examine further developmental changes in older children. Aggr. Behav. 30:164–173, 2004. © 2004 Wiley‐Liss, Inc. 相似文献

The purpose of this study was to examine the origins of gender differences in mutual gaze between infants and unfamiliar adults, using a prospective longitudinal design. Infant gaze behavior was measured twice: 13–112-hr and 13–18-weeks postpartum. Gender differences were found at Visit 2 due to an increase in girls' gaze behavior. Girls also made more eye contact in female–female dyads and in the second interaction over the first. Boys' behavior remained unchanged over time. The data provide evidence for gender differences in mutual gaze in a younger sample and wider context than previously demonstrated. Results are discussed in the context of social learning (i.e., Martin & Fabes, 2001, theory of “singular polarization”) and psychobiological theories of gender development. 相似文献
