This study examined the relationship between the similarity and accuracy of team mental models and compared the extent to which each predicted team performance. The relationship between team ability composition and team mental models was also investigated. Eighty-three dyadic teams worked on a complex skill task in a 2-week training protocol. Results indicated that although similarity and accuracy of team mental models were significantly related, accuracy was a stronger predictor of team performance. In addition, team ability was more strongly related to the accuracy than to the similarity of team mental models and accuracy partially mediated the relationship between team ability and team performance, but similarity did not. 相似文献

This study used trait activation theory as a theoretical framework to conduct a large-scale test of the interactionist explanation of the convergent and discriminant validity findings obtained in assessment centers. Trait activation theory specifies the conditions in which cross-situationally consistent and inconsistent candidate performances are likely to occur. Results obtained by aggregating correlations across 30 multitrait-multimethod matrices supported the propositions of trait activation theory, shedding a more positive light on the construct validity puzzle in assessment centers. Overall, convergence among assessment center ratings was better between exercises that provided an opportunity to observe behavior related to the same trait, and discrimination among ratings within exercises was generally better for dimensions that were not expressions of the same underlying traits. Implications for assessment center research and practice are discussed. 相似文献

Smaller Simon effects when stimulus locations are repeated on successive trials rather than alternated have been explained by the attention shift hypothesis, suggesting that shifts of attention result in interfering response codes. We investigated whether the attention shift hypothesis can also explain smaller flanker effects for repeated flankers than for alternated flankers, which occur only with directional information. In 3 peripheral letter identification tasks, target locations were cued by partial or complete flanker stimuli. Experiments 1 and 2 showed that directional flankers elicit shifts of attention. However, Experiment 3 revealed that directional flankers induced inverted cuing effects when reacting to the central target arrow was additionally required. These results are difficult to reconcile with the attention shift hypothesis as an explanation for the congruency reduction with repetitions of directional flankers. 相似文献

It is commonly assumed that successful innovation depends on creative idea generation: the more ideas are generated, the higher the probability of selecting a very good idea should be. However, research has shown that people do not perform optimally at idea selection and that ideational output may not contribute much to creative idea selection. The present studies aim to explain this phenomenon. We identified the strong tendency of our participants to select feasible and desirable ideas, at the cost of originality, as the main reason for their poor selection performance. Two manipulations of participants' processing of the available ideas (exclusion instructions and quality ratings) had no effect on selection effectiveness. In contrast, explicitly instructing participants to select creative or original ideas did improve selection effectiveness with regard to idea originality, but at the same time decreased participants' satisfaction and the rated effectiveness of chosen ideas. Results are discussed in relation to an effectiveness‐originality trade off. 相似文献

This study explored the impact of disruptive behavior disorder (DBD) comorbidity on a number of theoretically relevant outcomes among 192 children and adolescents with obsessive-compulsive disorder (OCD). Youth were divided into three groups: OCD Only, OCD+DBD comorbidity and OCD+Other comorbidity. Relative to those without a comorbid condition and those with any non-DBD comorbidity, comorbid DBD was associated with greater family accommodation and less symptom resistance. Youth with comorbid DBD exhibited greater OCD symptom severity, OCD-related impairment, anxiety, and internalizing problems than those with no comorbidity. Those with comorbid DBD were over 3.6 times as likely to be taking an atypical antipsychotic medication relative to children without comorbidity. The present results suggest that comorbid DBD contributes to more severe illness presentation above and beyond an OCD diagnosis alone, and may be associated with differing pharmacotherapy prescribing practices. 相似文献

We explore the justification and formulation of a four‐parameter item response theory model (4PM) and employ a Bayesian approach to recover successfully parameter estimates for items and respondents. For data generated using a 4PM item response model, overall fit is improved when using the 4PM rather than the 3PM or the 2PM. Furthermore, although estimated trait scores under the various models correlate almost perfectly, inferences at the high and low ends of the trait continuum are compromised, with poorer coverage of the confidence intervals when the wrong model is used. We also show in an empirical example that the 4PM can yield new insights into the properties of a widely used delinquency scale. We discuss the implications for building appropriate measurement models in education and psychology to model more accurately the underlying response process. 相似文献

The "risk-preference" thesis is a controversial topic in the sociology of religion. Thus far, cross-cultural empirical research on risk preference and religiosity has been meager. This study attempts to replicate Miller's ( Miller, Alan S. 2000 . Going to hell in Asia: The relationship between risk and religion in a cross cultural setting. Review of Religious Research 42(1):5–18) study for Taiwanese society, using data from the 2007 Taiwan Social Change Survey (TSCS). Logistic regression results show that for the Taiwanese (1) risk preference has little estimated net effect on religious affiliation, but (2) the relationship between risk preference and frequency of religious participation is statistically significant. 相似文献

A content analysis of research published in the Journal of Counseling Psychology (JCP) was conducted for Volumes 46 (1999) through 56 (2009). The analysis involved the placement of 514 articles in 15 substantive content categories. In addition, we identified the most frequently published authors, most frequent institutional affiliations, and several reported demographic characteristics. The principal areas of research activity in the JCP were multiculturalism and/or diversity, research on development and evaluation of tests and measures, personality and adjustment, outcome research, and interpersonal and/or social support and/or attachment, with these categories accounting for 57% of the articles published. Over 40% of the samples reported were college students, with a large number of samples including both genders and indicating the ethnic breakdown. This content analysis revealed that the JCP has remained consistent with its stated mission while incorporating changes in the field in its publications. 相似文献
