Research on imitation in infancy has primarily focused on what and when infants imitate. More recently, however, the question why infants imitate has received renewed attention, partly motivated by the finding that infants sometimes selectively imitate the actions of others and sometimes faithfully imitate, or overimitate, the actions of others. The present study evaluates the hypothesis that this varying imitative behavior is related to infants' social traits. To do so, we assessed faithful and selective imitation longitudinally at 12 and 15 months, and extraversion at 15 months. At both ages, selective imitation was dependent on the causal structure of the act. From 12 to 15 months, selective imitation decreased while faithful imitation increased. Furthermore, infants high in extraversion were more faithful imitators than infants low in extraversion. These results demonstrate that the onset of faithful imitation is earlier than previously thought, but later than the onset of selective imitation. The observed relation between extraversion and faithful imitation supports the hypothesis that faithful imitation is driven by the social motivations of the infant. We call this relation the King Louie Effect: like the orangutan King Louie in The Jungle Book, infants imitate faithfully due to a growing interest in the interpersonal nature of interactions.

ABSTRACT The current study investigated the influence of encoding modality and cue-action relatedness on prospective memory (PM) performance in young and older adults using a modified version of the Virtual Week task. Participants encoded regular and irregular intentions either verbally or by physically performing the action during encoding. For half of the intentions there was a close semantic relation between the retrieval cue and the intended action, while for the remaining intentions the cue and action were semantically unrelated. For irregular tasks, both age groups showed superior PM for related intentions compared to unrelated intentions in both encoding conditions. While older adults retrieved fewer irregular intentions than young adults after verbal encoding, there was no age difference following enactment. Possible mechanisms of enactment and relatedness effects are discussed in the context of current theories of event-based PM. 相似文献

This study explored the association between comprehensive psychological well-being and the metabolic syndrome (MS), as well as whether women without MS markers differ significantly from women with MS (three or more markers) on specific facets of psychological well-being. African (N=102) and Caucasian (N=115) women completed self-report questionnaires on psychological well-being, and biological markers for MS were determined. Results indicated a significant association between comprehensive psychological well-being and the MS in Caucasian women, but not in the case of African women. Caucasian women without MS had higher levels of perceived support from friends and family, environmental mastery, purpose in life, sense of coherence, affect balance and positive relationships than those with MS. African women without MS had higher levels of positive relationships and an optimistic explanatory style, but lower levels of perceived support from family. Further research is indicated. 相似文献

Abstract The distinctiveness of a face has been found to be an important factor in face recognition. We investigated the effect of the distinctiveness of a face upon subjects' speed and accuracy of recognition following different presentation times and retention intervals. It was found that (1) hits decreased with increasing delay; (2) false alarms increased and d primes decreased with a presentation time of 1 sec compared with 5 sec; (3) distinctive faces received more hits and higher d primes than non-distinctive faces; and (4) response latencies were shorter for distinctive targets than for distinctive distraction or non distinctive targets or distractors. These results were discussed in terms of the literature on the distinctiveness effect in face recognition. 相似文献

The purpose of this study was to examine high and low body dissatisfied (BD) men's and women's in-task emotional responses to the acute exposure of sex-specific physique slides of the aesthetic ideal (i.e., ideal slides) and themselves (i.e., self-slides). Participants were 35 male and 30 female university students who reported their immediate in-task emotional responses (i.e., pleasure and arousal) to viewing the self- and ideal slides. It was found that the (a) high BD women reported the least amount of pleasure while viewing the self- and ideal slides; (b) women reported less pleasure while viewing the self-slides than did the men; (c) The high BD group reported less pleasure while viewing the self- vs. the ideal slides than did the low BD group, and (d) the high BD men reported the most arousal of any of the groups while viewing the self- and ideal slides. The differing emotional responses of the men and women and the high and low BD groups to viewing the self- vs. ideal slides are discussed, and future research directions are suggested. 相似文献

The present study explored the relationship between level of employees' help-seeking behavior and their overall job evaluations. It was hypothesized that employees would seek more help from others whom they perceive as more knowledgeable than they are and that they would seek more help from superiors than from coworkers. Regarding the link between amount of help seeking and performance evaluations, it was predicted that the relationship between amount of help seeking and evaluations of overall job performance are curvilinear and affected by the perceived expertise of the helper. Study participants were employees of a chemical plant, and they reported on the amount of help seeking that they engaged in with superiors and coworkers. Data on the perceived expertise of the help seeker and the help giver in any helping interaction were collected. Most recent job performance evaluations as reported by participants' superiors served as a measure of job performance. The analyses indicate that in line with prediction, the relationships between help seeking and performance evaluations were curvilinear. These relationships were moderated by the help seeker's relative task-relevant expertise. The theoretical implications of these findings and suggestions for future research are discussed. 相似文献
