The impact of cross-training on team effectiveness 总被引:11,自引:0,他引:11
The authors examined the role of cross-training in developing shared team-interaction mental models, coordination, and performance in a 2-experiment study using computer simulation methodology (for Experiment 1, N = 45 teams; for Experiment 2, N = 49 teams). Similar findings emerged across the 2 experiments. First, cross-training enhanced the development of shared team-interaction models. Second, coordination mediated the relationship between shared mental models and team performance. However, there was some inconsistency in the findings concerning the depth of cross-training necessary for improving shared mental models. Results are discussed in terms of the impact of different levels of cross-training on team effectiveness. 相似文献

Participants engaged in a getting-acquainted interaction over an intercom after one participant (the perceiver) was provided with a positive (extraverted) or relatively negative (introverted) expectation about the other participant (the target). After completing evaluations of each other and the interaction, participants interacted for a second time. Prior to this second interaction, however, targets were made aware of the perceivers' initial expectation, told that it had been confirmed by their own behavior, and given a randomly assigned attribution (either dispositional or situational) about the perceived cause of their confirmatory behavior. Results demonstrated that targets made aware of dispositionally attributed and relatively negative expectations were more likely to increase in expectation-disconfirming behavior, compared to targets made aware of situationally attributed and relatively negative expectations, who were themselves more likely to continue to confirm the expectations. Implications for the study of behavioral confirmation of expectations and other interpersonal processes are discussed. 相似文献

The authors investigated children's responses to nonverbal expressions of conflict. Reactions of 3 groups of children (ranging in age from 6 to 16 years) to multiple forms of nonverbal conflict behaviors expressed in videotaped simulations of interadult disputes were examined. Results indicated that children make few discriminations between different forms of nonverbal conflict behaviors and that their reactions to nonverbal conflict are similar to their reactions to verbal conflict. Adults' expressions of fear elicited the most negative emotional responses from children, suggesting that children react to the meaning of conflict expressions and that expressions of fear may represent the greatest emotional security risks to children. Implications of these results for a theoretical model of the effects of forms of marital conflict on children are discussed (P. T. Davies & E. M. Cummings, 1994). 相似文献

Killeen and Hall (2001) showed that a common factor called strength underlies the key dependent variables of response probability, latency, and rate, and that overall response rate is a good predictor of strength. In a search for the mechanisms that underlie those correlations, this article shows that (a) the probability of responding on a trial is a two-state Markov process; (b) latency and rate of responding can be described in terms of the probability and period of stochastic machines called clocked Bernoulli modules, and (c) one such machine, the refractory Poisson process, provides a functional relation between the probability of observing a response during any epoch and the rate of responding. This relation is one of proportionality at low rates and curvilinearity at higher rates. 相似文献

Five experiments investigated the types of changes that disrupt the preview effect--the benefit gained in difficult search tasks from presenting some distractors earlier in time. A shape change with or without an overall luminance change at the location of an old item was found to disrupt the preview effect, whereas an equivalent luminance change alone or an isoluminant color change was not disruptive. Results suggest that (a) relatively low-level visual changes may not be sufficient to abolish the benefit, (b) the benefit most likely occurs through inhibition applied to locations within a location master map, and (c) inhibition need not be applied to surface features of objects. 相似文献

The phonological priming paradigm, in which participants respond to the second of 2 consecutively presented spoken words, has the potential to be a useful tool with which to study lexical processing. Concerns about response biases distorting the results have persisted since its introduction. This study explored the manifestation of biases by modifying the standard priming experiment such that the magnitude of priming effects using the same items could be compared at different points during the testing session. Four experiments investigated whether a recent dissociation of response biases and priming effects is evidence of lexical inhibition when the prime and target overlap by the first 3 word-initial phonemes (M. Hamburger & L. M. Slowiaczek, 1996). Biases were found in conditions previously thought to prevent their influence. 相似文献

In a series of experiments, we examined the effect of perceptual objects on visual attentional processing in the presence of spatially cued attentional selection. Subjects made speeded judgments about two visual elements that were either both on the same object or on two different objects. Judgments were faster when the elements were on the same object than when they were on different objects, revealing an object advantage. Importantly, the object advantage remained even when either exogenous or endogenous spatial cues were used to direct the subjects' attention to a part of the display, contrary to earlier findings of other researchers. The object advantage, however, did disappear when the stimulus duration was shortened substantially. The results show that object-based selection is pervasive and is not diminished by the act of selective attention. The results are discussed in terms of their implications for the mechanisms that underlie attentional selection. 相似文献

The authors argue against a purely behavioral definition of praise as verbal reinforcement in favor of the view that praise may serve to undermine, enhance, or have no effect on children's intrinsic motivation, depending on a set of conceptual variables. Provided that praise is perceived as sincere, it is particularly beneficial to motivation when it encourages performance attributions to controllable causes, promotes autonomy, enhances competence without an overreliance on social comparisons, and conveys attainable standards and expectations. The motivational consequences of praise also can be moderated by characteristics of the recipient, such as age, gender, and culture. Methodological considerations, such as including appropriate control groups and measuring postfailure outcomes, are stressed, and directions for future research are highlighted. 相似文献

This study, using secondary data analysis, examined prospectively a mediation model of the relationship between acculturation and problem behavior proneness among 330 Hispanic children and adolescents from an urban school district in the southwest region of the United States. Acculturation was predicted to have an indirect, but positive, relationship to problem behavior proneness through parental involvement and self-esteem. The results partially supported the model and indicated that parental involvement, but not self-esteem, played a significant mediational role in children's problem behavior proneness. The individual indicators of problem behavior proneness among Hispanic youth were significantly interrelated, which is consistent with problem behavior theory as conceptualized by R. Jessor (1984) and R. Jessor and S. L. Jessor (1977). Findings from this study provide implications for future research and intervention designs. 相似文献
