Self-control means choosing a large delayed reward over a small immediate reward; impulsiveness is its opposite. The metabolic hypothesis states that the amount of self-control across species correlates negatively with metabolic rate (Tobin & Logue, 1994). Foraging honeybees have high metabolic rates; the metabolic hypothesis would predict little self-control in bees. But foraging bees work for the longterm good of their hive, conditions that seem to require self-control. In three experiments, we gave bees the choice between (1) a sweeter delayed reward and a less sweet immediate reward and (2) a large delayed reward and a small immediate reward. Bees showed much self-control, inconsistent with the metabolic hypothesis. 相似文献

The present research investigated whether competition influences children's artistic creativity and intrinsic motivation toward an art activity. Study 1 tested the hypothesis that boys' creativity would be enhanced by competition, while girls' creativity would be undermined. Fifty children (aged 6–10) made paper collages in one of two conditions; half competed for prizes and half did not. Results supported our hypotheses, and further showed that when children self-segregated by gender, the impact of competition was much more pronounced. Study 2 was designed to clarify the unexpected gender-segregation finding from Study 1. The Children's Sex Role Inventory [Boldizar, J.P. (1991). Assessing sex typing and androgyny in children: the Children's Sex Role Inventory. Developmental Psychology, 27, 505–515] was administered to 143 children (aged 6–11). One week later, these children made paper collages in one of four conditions; in addition to manipulating competition, assigned seating ensured that half of children were segregated by gender and half were not. Following the collage activity, an intrinsic and extrinsic motivation questionnaire was administered. Masculine children reported higher levels of intrinsic motivation when competing and when segregated by gender; they also reported higher levels of extrinsic motivation, especially when segregated by gender. These findings demonstrate that gender role is an important factor in determining children's responses to competition. 相似文献

Several models of person perception predict that expectancy violations have both affective and cognitive consequences for the perceiver. Although extant evidence generally supports these claims, the temporal resolution of traditional self-report measures has limited researchers' ability to convincingly link underlying physiological processes with observed outcomes. In this study, we examined these issues by measuring brain (event-related brain potentials) and peripheral (facial electromyogram) electrophysiological activity while participants read positive and negative expectancy-consistent, expectancy-violating, expectancy-irrelevant, and semantically incongruent behavioral sentences about fictitious characters. The electromyogram results indicated that negative (but not positive) expectancy-violating behaviors elicited enhanced negative affect as early as 100 to 300 ms poststimulus. The event-related potentials showed enhanced positivities with latency exceeding 300 ms in response to expectancy violations and negative behaviors. Semantically incongruent sentence endings influenced a separate negative component (N400), suggesting fundamental differences between semantic- and behavior-consistency processing. This difference also was evident in participants' recall. Implications for theoretical models of expectancy violation are discussed. 相似文献

The present study addressed limitations of a recent confirmatory factor analytic study challenging the hypothesized factor structure of the Beavers Interactional Scales. That dataset (n = 97) was reanalyzed and two additional datasets (n = 95, n = 91) were explored. With all three samples, taken separately and together, the Beavers Systems Model, when operationalized in the BIS, was not supported. A body of evidence is accumulating which suggests that clinicians and researchers should be wary of the BIS. 相似文献

The purpose of this study is to explore a theological perspective toward genetic counseling. A survey was sent to 207 ministers within the Evangelical Lutheran Church of America (ELCA), to determine their perspectives toward four different scenarios in a prenatal genetic counseling setting. The four different scenarios included situations involving Huntington disease, Down syndrome, trisomy 18, and anencephaly. Nearly all ELCA Lutheran pastors perceived genetic counseling as beneficial and useful and wanted to be involved in the decision-making process for whether or not to terminate the pregnancy. Their views toward termination of pregnancy varied depending on the severity of the genetic abnormality. Severity in this study was based upon life compatibility. As the severity of the genetic abnormality increased, the percentage of Lutheran pastors who viewed termination as an option increased from 23% (Down syndrome) to 62% (anencephaly). A better understanding of how spiritual leaders view genetic counseling would provide an insight into how genetics and religious beliefs together play a significant role in shaping the decisions of those faced with abnormal pregnancies. 相似文献

Eight experts in Rational Emotive Behavior Therapy (REBT) provided personal examples of their own successes and failures in applying REBT to themselves. The experts actively talked to themselves both rationally and irrationally. Understandably, there were far more shoulds, oughts, musts, and have to's in the narratives in which the experts described when they failed to use REBT than when they succeeded in using REBT. Rational self‐talk was more prevalent in the examples of how REBT was successfully used by the experts. 相似文献

Recent research indicates that parental work stress has implications for the quality of family interaction and, in turn, children's and adolescents' adjustment. Studies in two distinct genres are reviewed: investigations relying on global reports of work demands, family dynamics, and child and adolescent adjustment and studies focusing on within-person comparisons of family interaction on days characterized by high and low work stress. The effects of parental work stress on children's and adolescents' adjustment appear to be indirect. Work stress is linked to parents' feelings of overload and strain, which in turn predict lower parent-child acceptance and higher conflict, processes that in turn are related to less positive adjustment of children and adolescents. In the face of high work stress, withdrawing from family involvement may be adaptive in the short run but ultimately problematic. The strength of these associations depends on parents' personality qualities, parents' coping styles, and work and family circumstances. 相似文献

A computerized version of the Silly Sentences task developed for use with children is found to be equivalent to the pencil‐and‐paper version from the SCOLP test with UK undergraduates, and is usable by a sample of young UK children. Because the sentences are presented aloud instead of being written, the computerized test is not affected by literacy skills. Translated into Kiswahili, the task was used in Tanzanian schools, despite the absence of an electricity supply and a very different cultural background. The decision latencies had a test–retest reliability of 0.69 over 5 months, and were independent of age and baseline decision speed. The task appears appropriate for longitudinal studies, including those in developing countries. Given its simplicity and the correlations with the original SCOLP version of the task, it may also be useful in studies on literate adults. Copyright © 2001 John Wiley & Sons, Ltd. 相似文献

Individuals advancing the status quo in partisan conflict are more favorably evaluated compared to individuals advocating change (Keltner & Robinson, 1997 ). We explore two aspects of this intergroup bias: first, a target effect whereby groups who aim to change the status quo are judged more negatively than those favoring its preservation; and second, an observer effect whereby those favoring the status quo define the conflict in terms of the status quo versus change to a greater extent than those advancing change. We sought to extend our understanding of these partisan effects via a minimal‐group induction of partisanship in the laboratory. In our study, participants viewed a negotiation between two group representatives, where half of the groups either defended the status quo or advocated change. As predicted, partisan observers: (a) favored the negotiator advancing the status quo (consistent with the target effect), (b) were more likely to attribute actions to the negotiators as stemming from their status quo versus change preference when they themselves were aligned with the status quo rather than change (consistent with the observer effect), and (c) when aligned with the status quo, expected a more effortful conflict than those seeking change (consistent with the observer effect). It is suggested that these biased perceptions are basic to intergroup, partisan processes involving change. Copyright © 2001 John Wiley & Sons, Ltd. 相似文献

This paper looks at how society has changed over the past ten years in terms of individual values, aspirations and consumer behaviour patterns, and relates these to underlying demographic, economic, technological and social trends. It summarises findings of research undertaken by the Future Foundation. The research identifies six ‘I’ factors, which, together, help to explain the different ways in which individuals are choosing to take control over an increasing number of areas of their lives. The most prominent of these are the desire for and reality of independence; individuality—the growing politics of difference; the changing nature and sources of identity; and interconnectedness—access to and use of information. The others are interactivity and imagination. It concludes that High ‘I’ values, although realised by a minority today, are aspired to by the majority and that all the economic, technological and attitudinal conditions are ripe for the ‘iSociety’, as it is called, to flourish and develop substantially over the next decade.
