Two main uses of categories are classification and feature inference, and category labels have been widely shown to play a dominant role in feature inference. However, the nature of this influence remains unclear, and we evaluate two contrasting hypotheses formalized as mathematical models: the label special‐mechanism hypothesis and the label super‐salience hypothesis. The special‐mechanism hypothesis is that category labels, unlike other features, trigger inference decision making in reference to the category prototypes. This results in a tendency for prototype‐compatible inferences because the labels trigger a special mechanism rather than because of any influences they have on similarity evaluation. The super‐salience hypothesis assumes that the large label influence is due to their high salience and corresponding impact on similarity without any need for a special mechanism. Application of the two models to a feature inference task based on a family resemblance category structure yields strong support for the label super‐salience hypothesis and in particular does not support the need for a special mechanism based on prototypes. 相似文献

Drawing on the social identity theory of leadership, we examined how leadership as an identity function alters perceptions and evaluations of in‐ and out‐group political leaders over time. Participants responded to two online questionnaires, before and after the 2012 U.S. Presidential election between Democrat Barack Obama and Republican Mitt Romney. We assessed respondents' strength of party identification, perceptions of each candidate's prototypicality, and evaluations of each candidate. Results supported the hypothesis: after his loss, Romney was presumably perceived as less prototypical of the Republican Party among strong identifiers, who symbolically revoked Romney's “license to fail.” Weakly identified Republicans were unaffected by his defeat, granting him a “license to fail.” Unexpectedly, Democrats and Republicans following his electoral success evaluated Obama more harshly. 相似文献

The primary purpose of the current study was to test a model examining the process by which parent dispositional mindfulness relates to youth psychopathology through mindful parenting and parenting practices. The universality of the model across youth at three developmental stages was examined: young childhood (3–7 years; n?=?210), middle childhood (8–12 years; n?=?200), and adolescence (13–17 years; n?=?205). Overall, participants were 615 parents (55 % female) and one of their 3-to-17 year old children (45 % female). Parents reported on their dispositional mindfulness, mindful parenting, positive and negative parenting practices and their child’s or adolescent’s internalizing and externalizing problems. Consistent findings across all three developmental stages indicated that higher levels of parent dispositional mindfulness were indirectly related to lower levels of youth internalizing and externalizing problems through higher levels of mindful parenting and lower levels of negative parenting practices. Replication of these findings across families with children at different developmental stages lends support to the generalizability of the model. 相似文献

The typical assumption that performance is distributed normally has come under question in recent years (e.g., O'Boyle & Aguinis, 2012). This paper uses a dynamic, computational model of performance‐as‐results to examine possible sources of such distributions. That is, building off the classic model of job performance (Campbell & Pritchard, 1976), components of a dynamic model are examined in 4 separate experiments using Monte Carlo simulations. The experiments indicate that positively skewed distributions can arise from pure luck, multiplicative combinations of factors where 1 of those factors has a zero origin, Matthew effects associated with learning, and feedback effects of performance on resource allocation policies by external agents. The results are discussed in terms of explanations for positively skewed performance distributions and the use and expansion of the computational model for examining dynamic performance more generally. 相似文献

There is a set of competing theories for how emotion influences behavior after being psychologically challenged. One group of theories emphasize that positive affect enhances performance after a psychological challenge. Conversely, the emotion and goal compatibility theory argues that positive and negative emotions can enhance or reduce performance and motivation to control behavior depending on the task requirements. To test these contrasting predictions, participants were psychologically challenged by completing a Stroop task and then induced into a positive, negative, or neutral mood. A verbal or spatial working memory task was then completed to assess performance and motivation to control behavior. As predicted, positive mood benefited performance and behavioral control on the verbal working memory task, whereas, a negative mood benefited performance and behavioral control on the spatial working memory task. Thus, following a psychological challenge motivation to control behavior depended on interactions between mood and task requirements consistent with the emotion and goal compatibility theory.

The effects of emotion on working memory and executive control are often studied in isolation. Positive mood enhances verbal and impairs spatial working memory, whereas negative mood enhances spatial and impairs verbal working memory. Moreover, positive mood enhances executive control, whereas negative mood has little influence. We examined how emotion influences verbal and spatial working memory capacity, which requires executive control to coordinate between holding information in working memory and completing a secondary task. We predicted that positive mood would improve both verbal and spatial working memory capacity because of its influence on executive control. Positive, negative and neutral moods were induced followed by completing a verbal (Experiment 1) or spatial (Experiment 2) working memory operation span task to assess working memory capacity. Positive mood enhanced working memory capacity irrespective of the working memory domain, whereas negative mood had no influence on performance. Thus, positive mood was more successful holding information in working memory while processing task-irrelevant information, suggesting that the influence mood has on executive control supersedes the independent effects mood has on domain-specific working memory. 相似文献

The relationship between vocal pitch and social anxiety has been examined with encouraging results across a growing number of studies, highlighting increased fundamental frequency (F0) as a potential disorder-specific physiological marker of social anxiety. The purpose of the present study was to examine the relationship between mean F0 emitted during diagnostic interviews and social anxiety disorder (SAD) symptoms. Patients who qualified for a diagnosis of SAD (n?=?26) and a subsample of demographically-matched healthy controls (HCs; n?=?12) were administered clinical diagnostic interviews. We examined mean F0 emitted during select segments of the diagnostic interviews utilizing specialized vocal analysis equipment. Men (but not women) who qualified for a diagnosis of SAD emitted greater overall mean F0 in comparison to HCs throughout the course of the diagnostic interviews, and mean F0 emitted during the introductory segment of the diagnostic interviews was positively related to SAD symptoms for men (but not women). Furthermore, a previously-established threshold of mean F0 which demonstrated excellent differentiation between men with SAD and controls was successfully replicated in the present design, with regard to F0 emitted during the introductory segment of the interviews. These results provide strong additional support for increased F0 as a physiological indicator and behavioral marker of SAD in samples of men. Implications for the assessment and treatment of SAD are discussed. 相似文献
