A meta-analysis of team-efficacy,potency, and performance: interdependence and level of analysis as moderators of observed relationships 总被引:7,自引:0,他引:7
Meta-analytic techniques were used to examine level of analysis and interdependence as moderators of observed relationships between task-specific team-efficacy, generalized potency, and performance. Sixty-seven empirical studies yielding 256 effect sizes were identified and meta-analyzed. Results demonstrated that relationships are moderated by level of analysis. Effect sizes were stronger at the team level (p = .39) than at the individual level (p = .20). At the team level, both team-efficacy and potency had positive relationships with performance (ps = .41 and .37, respectively). Interdependence significantly moderated the relationship between team-efficacy and performance, but not between potency and performance. The relationship between team-efficacy and performance was stronger when interdependence was high (p = .45) than when it was low (p = .34). 相似文献

When Western Scrub-Jays (Aphelocoma californica) cached and recovered perishable crickets, N. S. Clayton, K. S. Yu, and A. Dickinson (2001) reported that the jays rapidly learned to search for fresh crickets after a 1-day retention interval (RI) between caching and recovery but to avoid searching for perished crickets after a 4-day RI. In the present experiments, the jays generalized their search preference for crickets to intermediate RIs and used novel information about the rate of decay of crickets presented during the RI to reverse these search preferences at recovery. The authors interpret this reversal as evidence that the birds can integrate information about the caching episode with new information presented during the RI. 相似文献

Despite the fact that several theories suggest that people's self-esteem is affected by social approval and disapproval, many individuals steadfastly maintain that how other people regard them has no effect on how they feel about themselves. To examine the validity of these beliefs, two experiments compared the effects of social approval and disapproval on participants who had indicated either that their self-esteem is affected by how other people evaluate them or that their self-esteem is unaffected by interpersonal evaluation. Results of both studies converged to show that approval and disapproval clearly affected the self-esteem of even those individuals who denied that social evaluations affected their feelings about themselves. 相似文献

Bioethics has developed against a backdrop of increased concern for human and civil rights, including the rights of patients to decide about their own treatment. The recent case of Laleh and Ladan Bijani, the twenty-nine-year old Iranian conjoined twins who died in a Singapore hospital on Jul 8, after more than fifty hours of surgery aimed at separating them, highlights the tensions between respect for patient autonomy and professional medical judgment. 相似文献

This study examines the time budgeted to different behaviors in Aplysia fasciata under three conditions: (1) animals have constant access to food and mates: (2) there is access to food, but not to mates; (3) neither food nor mates are present. The data suggest a number of rules underlying behavioral integration: (1) Feeding, reproductive behaviors, and activity seem to be natural categories for behavioral choice. Feeding and reproductive behaviors are controlled in tandem by a common arousal mechanism, while time left over after animals feed and reproduce is distributed in a fixed ratio between locomotion (crawling and swimming) and inactivity (immobility and movement in place). (2) Relative distribution between different forms of locomotion and inactivity is modified by changes in motivational state. More time is spent swimming than crawling when feeding and/or mating is prevented, while more time is spent moving in place than immobile when the arousal level is increased. (3) Feedback control of feeding and reproduction is asymmetric. Satiation of feeding inhibits the common arousal. In the absence of food, time spent on reproductive behaviors increases due to disinhibition of the common arousal. By contrast, positive feedback arising from sexual behavior excites the common arousal. When mating is prevented by removing potential mates, time spent feeding decreases. (4) Generally, animals choose between performing the three main categories of behavior. Although Aplysia simultaneously can feed and mate, or locomote and mate, they do so infrequently. By contrast, different types of reproductive behaviors (male mating, female mating, egg-laying) are commonly performed simultaneously. 相似文献

Parent Ratings of Attention-Deficit/Hyperactivity Disorder Symptoms: Factor Structure and Normative Data 总被引:6,自引:0,他引:6

Changes in the diagnostic criteria for attention-deficit/hyperactivity disorder (ADHD) have necessitated the creation of new measures for clinical assessment. The factor structure of a parent rating scale containing the 18 symptoms of ADHD was examined in this study. Factor analyses and assessment of differences in ADHD ratings across sex, age, and ethnic group were conducted using a sample of 4666 participants ranging in age from 4 to 20 years old who attended kindergarten through 12th grade in 22 school districts across the United States. Two factors (Inattention and Hyperactivity–Impulsivity) were derived and normative data for a nationally representative sample are presented. A higher frequency of ADHD symptoms was found for boys, younger children, and African-American participants. Potential uses of this scale in clinical practice and research are discussed. 相似文献

The Emotion Regulation Questionnaire (ERQ; Gross & John, 2003) assesses two emotion regulation (ER) strategies: cognitive reappraisal and expressive suppression. Researchers have used the ERQ in cross-national studies, such as with participants in Hong Kong. There is inconsistency in psychometric equivalence data for the ERQ in Chinese among adults, and prior research in Hong Kong contradicted the ERQ's original factor structure (Matsumoto et al., 2008). The present study examined the factor structure, reliability and validity of a translated Traditional Chinese-ERQ and the English-ERQ with Hong Kong college students. Results revealed that both versions replicated the original two-factor structure of the ERQ (Gross & John, 2003). Evidence of the measure's convergent, discriminant and predictive validity was obtained as well. Implications for cross-cultural scale validation particularly with Hong Kong Chinese students are discussed. 相似文献

It is important to demonstrate replicable evidence of the effectiveness of counselling procedures. The study aimed to contribute to the currently limited evidence base examining the effectiveness of university student counselling in the UK. Information on therapeutic outcome [based on Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM) scores] for 305 individuals attending a large UK university counselling service was analysed. Following counselling intervention: there was a statistically significant improvement in CORE-OM scores with 63% of individuals showing a reliable improvement and only 2% showing a reliable deterioration. Of those who began with a score in the clinical range, 49% showed a clinically significant change. These results provide additional evidence for the effectiveness of university counselling interventions. Future research should aim to build on this preliminary research using randomised controlled trial designs. 相似文献

Artificial language learning (ALL) experiments have become an important tool in exploring principles of language and language learning. A persistent question in all of this work, however, is whether ALL engages the linguistic system and whether ALL studies are ecologically valid assessments of natural language ability. In the present study, we considered these questions by examining the relationship between performance in an ALL task and second language learning ability. Participants enrolled in a Spanish language class were evaluated using a number of different measures of Spanish ability and classroom performance, which was compared to IQ and a number of different measures of ALL performance. The results show that success in ALL experiments, particularly more complex artificial languages, correlates positively with indices of L2 learning even after controlling for IQ. These findings provide a key link between studies involving ALL and our understanding of second language learning in the classroom. 相似文献
