When using sample data to decide whether two populations differ, laypeople attend to the difference between group means, but largely overlook within-group variability (Obrecht, Chapman, & Gelman, 2007). We show, first, that laypeople know about and use story-implied variability when making pairwise comparisons. Then we demonstrate that participants’ sensitivity to variance in a dataset is boosted when presented in a context that implies consistent variance information. Statistical data were couched in stories about electrical conductivity measurements obtained from element samples (low-variability category) or body weight measurements from samples of peoples (high-variability category). We manipulated, between participants, whether the data variance matched or mismatched the story-implied variability. Participants who received data in a matching context showed high sensitivity to variance, while those in the mismatching condition did not. Laypeople use statistical data to make reasonable inferences when those data are provided in a context that makes sense. 相似文献

Jehn (e.g., 1997) offered three distinct types of team conflict, namely, task conflict, relationship conflict, and process conflict. Despite existing meta-analyses, there remain important and ongoing issues that warrant further meta-analytic investigation. Our contribution is threefold. First, we report novel meta-analytic findings involving moderators of the conflict–team performance relationship. Second, we report on meta-analytic correlations involving all three conflict types and team innovation. Third, we report on the relations involving task conflict and relationship conflict with previously unexamined, but critical, teamwork variables: team potency, cooperative behaviors, competitive behaviors, and avoidance behaviors. Input for the current meta-analysis included 89 independent samples, 6,122 teams, and approximately 28,000 team members. 相似文献

Researchers have postulated that individual differences in intolerance of uncertainty (IU) may affect people's health behaviours. Study 1 (N?=?147 university students) supports this proposition showing that higher IU is associated with higher monitoring (seeking threat-relevant information). Study 2 (N?=?117 university students) experimentally manipulated IU to ensure that the association is not due to other related constructs such as anxiety or worry. Results show that inducing high IU led to increased monitoring as reflected by higher scores on an index of monitoring measures. Wanting information about the health threat in order to reduce their uncertainty was an independent predictor of monitoring and did not mediate the relationship between IU and monitoring. Findings suggest that high IU induces people to increase their monitoring; an adaptive strategy when the health threat can be reduced through this behaviour. 相似文献

Individual differences in the weighting of positive versus negative information when generalizing attitudes towards novel objects predict a variety of assessments that involve the integration of valence information (Pietri, Fazio, & Shook, 2013). The goal of the current research was to manipulate valence weighting in attitude generalization to demonstrate its causal impact on various judgments and behaviors. In four experiments, participants first played BeanFest—a game in which they approached/avoided novel stimuli (beans) varying in shape and speckles, in order to increase and not decrease their points (Fazio et al., 2004). Following the game, participants classified game beans, and novel ones that varied in resemblance to the game beans as either positive or negative. In the recalibration condition, participants were told whether each classification was or was not correct. Thus, they received feedback regarding the appropriate valence weighting of resemblance to a known positive versus a known negative. In Experiment 1, this recalibration influenced individuals' attitude generalizations regarding other (non-bean) novel objects. We then examined if recalibration would produce far-transferring effects by influencing interpretations of ambiguous situations (Experiment 2), risk assessments (Experiment 3), and finally risk-taking behavior (Experiment 4). Across the four experiments, the recalibration procedure led participants who were initially relatively cautious to be more positive when making these various judgments, whereas people who exhibited an initial risky bias became more negative as a function of recalibration. 相似文献

This article presents a concept underlying excellence called resonance , which was developed based on research interviews and consulting practice with high-level performers from all walks of life. Findings suggest that many high-caliber performers follow a typical process as they become experts in their chosen field. They have a dream , which represents how they want to feel in their daily pursuits. They also engage in extensive preparation, which includes activities that enable them to live their dream. All of the participants faced obstacles, but they developed strategies to revisit their dream before they actually engaged in more preparation. This cyclical process that guided their performance and life has been termed resonance , which occurs when there is a seamless fit between their internal self and their external environment. It is captured in the resonance performance model (RPM), a heuristic model devised to guide the practice of consultants. The article also includes a discussion of the RPM in relation to other performance-related concepts such as flow, presents some recent and future research with resonance, and considers practical application for consultants who may be interested in using the RPM. 相似文献

We evaluated whether generalized conditioned reinforcers mitigate the effects of satiation with an individual with intellectual disabilities. Previous research indicates that generalized conditioned reinforcers are not sensitive to satiation effects. However, this effect has not been investigated on varying classes of backup reinforcers. First, we established a highly preferred (HP) edible as a reinforcer. Then, we provided presession access to the HP edible, and, in a multi‐element comparison, the participant could either earn tokens for only the HP edible, for edibles that were similar to the HP edible, for edibles that were dissimilar to the HP edible, or earn no tokens. A decreasing trend in responding for the HP edible was observed following presession access. Furthermore, the participant completed the task at a high rate when backup reinforcers were dissimilar to the HP edible. Results suggest that varying the classes of stimuli that are used as backup reinforcers may increase the effectiveness of generalized conditioned reinforcers.

Little is known about how ethnic identity influences bullying. Using a racially diverse sample, we examine how within-race perceptions match experiences. We utilize bivariate probit regression to examine the correlation between actual and perceived victimization and bullying experiences. Results suggest no differences in victimization by ethnicity but perceived victimization differed across groups. Perceived and actual bullying differed across all groups. School climate acted as a protective factor against bullying and victimization, but school diversity increased the likelihood of bullying by whites and Latinos. These findings shed light on the importance of ethnic identity in understanding the etiology of bullying. 相似文献

Older adults with major depressive disorder (MDD) may also have preclinical Alzheimer’s disease (AD). Differential diagnosis is quite challenging due to the overlapping symptoms of MDD and AD. In the current study, we predicted that impaired long-term memory (an area most affected in early AD), but not executive function (an area affected in MDD and AD), would distinguish older depressed patients who developed AD from those who did not. Patients (N = 120) assessed as having MDD but not dementia at baseline were administered tests of cognitive function and followed longitudinally for subsequent diagnosis of AD. Using structural equation modeling we found a latent construct of long-term memory to be associated with AD to a greater extent than executive functioning. Additional analyses to enhance clinical utility of findings indicated that individual tests of episodic memory were most predictive of AD status. Tests of long-term memory can be utilized by the clinician when assessing for preclinical AD among depressed elderly. 相似文献
