Four actors were requested to perform Sartre's No Exit after a retention interval of more than 5 months. Their recall of the play was studied either with the spatial and visual contextual cues normally available during a performance or without such cues. Total recall was still considerable, equalling 85%. The number of paraphrases of, and inferences on, the original text was however quite large (32%), suggesting that the actors had learned their lines according to their meaning rather than as a result of rote memorisation. The context manipulation showed that actors' recall is facilitated by the availability of spatial-visual information, but only to a limited extent. The relative importance of textual and contextual cues in the long-term retention of a play is discussed. 相似文献

Before discussing how to innovate the study of career development using insights from life-span psychology and life course sociology, researchers might benefit from reconsidering whether they are studying careers or studying vocational behavior. While the word “career” seems ubiquitous in vocational psychology research, there are important differences between the study of vocational behavior, occupational roles, and career development. In this article, I urge researchers to (a) reconsider the meaning of career and research on career development, (b) adopt prospective, longitudinal research designs, and (c) concentrate first on processes of development and then on the content of careers. Considering these suggestions may ready vocational psychology for true innovations such as studying human development through work and relationships. 相似文献

The primary purpose of the study was to identify event-based prospective-memory tasks that provide sensitive and reliable tools for assessing effects of normal aging in prospective-memory performance. Four prospective-memory tasks were selected from the literature or were newly developed, with the tasks differing on various dimensions that, for theoretical reasons or based on previous evidence, might determine task sensitivity to age effects on prospective-memory performance: perceptual saliency of prospective target events, frequency of occurrence of prospective target events, complexity of prospective-memory instructions, and provision of feedback after prospective-memory errors. Two of the four tasks yielded large and robust age effects on prospective-memory performance. Correlational analyses suggested that these age effects on prospective-memory performance were mediated, at least in part, by a reduced ability of older adults to maintain prospective intentions in a highly activated state and not by age effects on basic mental speed alone. 相似文献

Characteristics of marital conflict when children (8-16 years) were present versus absent were compared on the basis of 47 mothers' and fathers' reports during a 15-day period. Mothers described 669 incidents of marital conflict, and fathers described 551 incidents. About two thirds of the conflicts occurred in children's absence. Contrary to predictions, conflicts in which children were present were more negative (e.g., more negative emotions, more destructive conflict tactics) and more often about children than were child-absent conflicts. Although parents may attempt to protect children from conflict exposure, children tend to be exposed to a relatively hostile and emotionally negative subset of the marital conflicts that occur in the home. 相似文献

Infant Syrian golden hamsters (Mesocricetus auratus) do not exhibit endogenous heat production before 3 weeks of age and do not huddle effectively during cold exposure, gaining little thermoregulatory benefit from the presence of multiple littermates. In contrast, infant Norway rats (Rattus norvegicus) produce heat endogenously and are effective at maintaining elevated body temperatures by huddling. Therefore, the ineffective huddling of infant hamsters may be due to the absence of endogenous heat production. The huddling behavior of infants in mixed huddles of 8-day-old hamsters and weight-matched 4-5-day-old rats was observed to explore this possibility. The results indicate that hamsters, even when cold, effectively gain access to heat-producing rats, supporting the idea that endothermy contributes to the behavior of huddling by providing heat to each individual and thermal stimuli to other infants to support aggregation. 相似文献

We examine how group members paradoxically refuse intergroup help where they might need it most: in the moral status domain. Based on the Sacred Value Protection Model (Tetlock, 2002), we predicted and found that group members felt stronger group-based anger and a stronger motivation to reaffirm their group's moral status when an outgroup was morally superior to them. Despite this moral motivation, however, we also predicted and found that group members more strongly refused intergroup help to improve their moral status vis-à-vis the morally superior outgroup (compared to an uninvolved outgroup). Consistent with the Social Identity model of Deindividuation Effects (Reicher, Spears, & Postmes, 1995), group members thus strategically refused intergroup help to defend their group identity. Supporting this interpretation, particularly highly identified group members were most likely to refuse intergroup help when they needed it most. We discuss theoretical and practical implications of our findings. 相似文献

A new paradigm is implicit within the constructivist and narrative methods for career intervention that have emerged in the 21st century. This article makes that general pattern explicit by abstracting its key elements from the specific instances that substantiate the new conceptual model. The paradigm for life design interventions constructs career through small stories, reconstructs the stories into a life portrait, and coconstructs intentions that advance the career story into a new episode. 相似文献

The present research examines the role of optimism on time preferences for both losses and gains. It is argued that optimism has asymmetric effects on time preferences for gains versus losses: one reason why decision makers prefer immediate gains is because they are optimistic that these gains will be followed by additional gains in future. In contrast, decision makers prefer to delay losses because they are optimistic that losses are avoidable in the future. Optimism about outcomes affects time preferences for both gains and losses, such that low optimism reduces the discount rates while increased optimism is associated with higher discount rates. This prediction was supported in two different domains: monetary outcomes (Study 1), and health (Study 2). Implications of these results for both research practice and time preferences in the real world are discussed. 相似文献
