Adolescent males and females (grades 6–12) (n = 552) were presented with nine brief vignettes from the Teen Apperception Scale, describing high-achieving hypothetical female (or male) peers, across nine domains: leadership, academics, athleticism (two), musicianship, art, popularity, humor, and multitalentedness. Teens rated likability, popularity, and attractiveness of vignette subjects in each domain. The sample was roughly evenly divided by gender (47% male and 53% female); students ranged in age from 11 to 18 years. The sample was ethnically diverse, and the socioeconomic status of the students' families ranged from lower middle to upper middle class. MANOVA analyses showed female vignette subjects to be rated significantly higher than male subjects by both genders and all grade groupings, at p < .0001 overall, and at values ranging from p < .05 to p < .0001 for six of nine subscales. Results are contrasted with those from highly similar studies 30 years ago, and used to reflect a possible shift in attitudes toward high achievement in women. 相似文献

Transformational leadership, initiating structure, and selected substitutes for leadership were studied as longitudinal predictors of performance in 118 research and development (R&D) project teams from 5 firms. As hypothesized, transformational leadership predicted 1-year-later technical quality, schedule performance, and cost performance and 5-year-later profitability and speed to market. Initiating structure predicted all the performance measures. The substitutes of subordinate ability and an intrinsically satisfying task each predicted technical quality and profitability, and ability predicted speed to market. Moderator effects for type of R&D work were hypothesized and found whereby transformational leadership was a stronger predictor of technical quality in research projects, whereas initiating structure was a stronger predictor of technical quality in development projects. Implications for leadership theory and research are discussed. 相似文献

A lengthened response time when a distractor becomes a target, called negative priming, is an undisputed phenomenon in selective attention, yet just what the underlying mechanism responsible for negative priming is has not been resolved. In this study, the proportion of attended repetition trials was manipulated in order to test the predictions of three theories that have been proposed for explaining spatial negative priming: distractor suppression (e.g., Tipper, 1985), episodic memory retrieval (e.g., Neill, Valdes, &; Terry, 1995), and novelty bias (e.g., Milliken, Tipper, Houghton, &; Lupiáñez, 2000). The results supported the proposal that a novelty bias, which is flexible and can be overridden, is the primary mechanism responsible for priming in spatial tasks. Memory retrieval obscured the novelty bias for target processing, was more selective in older adults, and did not affect distractor processing. Novelty bias and distractor suppression may share the same inhibitory attentional mechanism. 相似文献

Memory conjunction errors, that is, when a combination of two previously presented stimuli is erroneously recognized as previously having been seen, were investigated in a face recognition task with drawings and photographs in 23 individuals with learning disability, and 18 chronologically age-matched controls without learning disability. Compared to the controls, individuals with learning disability committed significantly more conjunction errors, feature errors (one old and one new component), but had lower correct recognition, when the results were adjusted for different guessing levels. A dual-processing approach gained more support than a binding approach. However, neither of the approaches could explain all of the results. The results of the learning disability group were only partly related to non-verbal intelligence. 相似文献

Half of cerebral palsy (CP) arises in infants of normal birthweight; yet, many fewer studies seek to identify risk factors for CP in term and near-term infants than in those born very prematurely. There has been no net decrease in the prevalence of CP in term and near-term infants over recent decades. Potentially asphyxiating birth complications account for a small minority of CP cases. Recent studies suggest that disorders of coagulation and intrauterine exposure to infection or inflammation are associated with risk of CP, and that both can be accompanied by signs of neonatal encephalopathy, the best available predictor of CP in term neonates. Therapeutic interventions directed at preventing interruption of oxygen supply have not been shown to reduce the occurrence of CP. There have not yet been studies examining whether medical interventions directed at infection or coagulation disorder can reduce the frequency of CP. 相似文献

We sought to replicate and extend Carroll and Hesse's (1987) study of the acquisition of tacts by including participants with and without developmental disabilities. As in Carroll and Hesse, the present results showed that mand-tact training, rather than tact-only training, led to more rapid acquisition of tacts. Tacting on follow-up tests did not differ. In addition, our results show that mand-tact training established both verbal operants involved about as rapidly as tact-only training established only one verbal operant.

Information ambiguity is prevalent in organizations and may influence management decisions. This study examines, given imprecise probabilities or outcomes, how managers decide which department's performance to investigate further when they are provided with performance benchmarks expressed in numerical intervals. Seventy‐nine MBA students participated in two experiments involving investigation decisions. We presented participants with interval benchmarks of a firm's expenses. Being below or above the benchmark should have been seen as equally negative. We found that, when facing outcome ambiguity, our participants consistently preferred to investigate further those departments whose performance was described as having an ambiguous outcome (when the outcome's range was centered either below or above the interval benchmark). However, when facing probabilistic ambiguity, there were two predominant choice patterns: consistently choosing to investigate the department whose performance is described with an ambiguous probability, or consistently choosing to investigate the department with unambiguous performance. To gain further insight, we conducted a follow‐up study collecting written protocols of participants' reasons for making choices involving ambiguous performance information. The results show that our participants displayed similar decision‐making processes when facing outcome ambiguity and probabilistic ambiguity. Copyright © 2001 John Wiley & Sons, Ltd. 相似文献

Marital Conflict and Risk for Child Maladjustment over Time: Skin Conductance Level Reactivity as a Vulnerability Factor 总被引:4,自引:0,他引:4
Skin conductance level reactivity (SCLR) was examined as a longitudinal mediator and moderator of relations between parental marital conflict and psychopathology among children and young adolescents. Participants were 157 boys and girls (M age at T1 = 9.31 years; SD = 1.97); there was a 2-year lag between T1 and T2 assessments. At T1, participants' SCLR was assessed in response to lab challenges. Parents completed measures of aggressive marital conflict and child adjustment at T1 and T2. Supportive of moderation effects, T1 marital conflict interacted with T1 SCLR and gender in the prediction of changes in maladjustment. The link between marital conflict and increased internalizing and externalizing symptoms was stronger for girls with higher SCLR than girls with lower SCLR. Marital conflict predicted increased externalizing behaviors for boys with lower SCLR but not higher SCLR, although levels of externalizing behaviors were similar among boys with lower and higher SCLR especially at higher levels of marital conflict. Findings build on the literature by illustrating the importance of examinations of both family risk and youth biological vulnerability for the prediction of psychopathology. 相似文献

Ensemble musicians play in synchrony despite expressively motivated irregularities in timing. We hypothesized that synchrony is achieved by each performer internally simulating the concurrent actions of other ensemble members, relying initially on how they would perform in their stead. Hence, musicians should be better at synchronizing with recordings of their own earlier performances than with others' recordings. We required pianists to record one part from each of several piano duets, and later to play the complementary part in synchrony with their own or others' recordings. The pianists were also asked to identify their own recordings. The pianists were better at synchronizing with their own than with others' performances, and they were able to recognize their own recordings. Furthermore, synchronization accuracy and recognition were correlated: Pianists who were relatively accurate at synchronizing with their own performances were also good at recognizing them. Thus, action simulation may underlie both synchronization and self-recognition. 相似文献
