We explore how the choices available to individuals planning multi‐task work can facilitate the incubation of ideas and enhance creative performance. Using opportunistic assimilation theory, we hypothesize that two considerations can determine the effectiveness of incubation and creative performance. First, we argue that having the discretion to switch tasks when needed, as well as the timing of this discretionary switch between tasks (i.e., earlier versus later in the work process on the main task) is important. Second, the scope of the intervening task (i.e., in the same knowledge domain as the main task versus in a different domain) can lead to more effective incubation and creativity. Results of a laboratory study indicate that participants who made a discretionary switch to an intervening task later in their work process on the main task benefited significantly more in terms of creative performance than those who chose to switch earlier in their work process or chose not to switch tasks. Additionally, participants who worked on an in‐domain intervening task exhibited significantly higher creativity on the main task than those who worked on an out‐of‐domain intervening task. Furthermore, focus of attention on the main task partially mediated these results.  相似文献

We introduce and extend the classical regression framework for conducting mediation analysis from the fit of only one model. Using the essential mediation components (EMCs) allows us to estimate causal mediation effects and their analytical variance. This single-equation approach reduces computation time and permits the use of a rich suite of regression tools that are not easily implemented on a system of three equations. Additionally, we extend this framework to non-nested mediation systems, provide a joint measure of mediation for complex mediation hypotheses, propose new visualizations for mediation effects, and explain why estimates of the total effect may differ depending on the approach used. Using data from social science studies, we also provide extensive illustrations of the usefulness of this framework and its advantages over traditional approaches to mediation analysis. The example data are freely available for download online and we include the R code necessary to reproduce our results.  相似文献

Risks and rewards, or payoffs and probabilities, are inversely related in many choice environments. We investigated people's psychological responses to uncommon combinations of risk and reward that deviate from learned regularities (e.g., options that offer a high payoff with an unusually high probability) as they evaluated risky options. In two experiments (N = 183), participants first priced monetary gambles drawn from environments in which risks and rewards were negatively correlated, positively correlated, or uncorrelated. In later trials, they evaluated gambles with uncommon combinations of risk and reward—that is, options that deviated from the respective environment's risk–reward structure. Pricing, response times, and (in Experiment 2) pupil dilation were recorded. In both experiments, participants took more time when responding to uncommon compared to foreseeable options or when the same options were presented in an uncorrelated risk–reward environment. This result was most pronounced when the uncommon gambles offered higher expected values compared to the other gambles in the set. Moreover, these uncommon, high‐value options were associated with an increase in pupil size. These results suggest that people's evaluations of risky options are based not only on the options' payoffs and probabilities but also on the extent to which they fit the risk–reward structure of the environment.  相似文献

With addictive disorders frequently co-occurring among patients with borderline personality disorder (BPD), exploring factors that may influence health-related behaviours, like religious involvement, is important. This study assesses whether religious involvement is associated with smoking and alcohol use disorders (AUDs) in BPD subjects. This study used data from Wave 2 of the National Epidemiological Survey on Alcohol and Related Conditions (NESARC), which used the Alcohol Use Disorder and Associated Disabilities Interview Schedule–DSM-IV (AUDADIS-IV) as its assessment instrument. The AUDADIS-IV assessed personality disorders, tobacco usage, the presence of AUDs, and religious involvement. Attending a place of worship and weekly or more frequent worship attendance were significantly associated with reduced likelihood of current smoking and AUDs among BPD subjects. AUDs were also significantly less common in those reporting higher subjective religiousness. In conclusion, people with BPD who are religiously inclined are less likely to engage in addictive behaviours, specifically smoking and AUDs.  相似文献

Although interest development is often conceptualized as a process that occurs within an individual, interest can be developed through various social mechanisms. Messages that suggest that one is or is not welcome within a context may serve to bolster or attenuate interest in those contexts. In a sample of first semester freshmen undergraduate science students, we tested whether or not talking with close others about one’s interests, and receiving social recognition during those conversations, was related to having a greater science career interest over time. Our findings suggest that the way in which students perceive others’ reactions to their scientific interests (social recognition) during these conversations may have the greatest impact on students that face greater external barriers to persisting. We found that positive social recognition appraisals that convey that a listener understands and encourages one’s interest in science predicted a greater science career interest over time for women, but not men. The impact of positive social recognition appraisals on interest in a science career was greatest among women with relatively low or average science identities, but not for women with a relatively high science identity. The implications for the development of students’ interest and for broadening participation in science are discussed.

As the nature of work has changed in recent decades, employees are increasingly exposed to psychological demands in the workplace, which have associated consequences for employees, organizations, and society. Using self-determination theory, this study examined the dark side of work, in which frustration of basic psychological needs is associated with higher levels of work-related stress. In this model, work-related stress is associated with higher levels of somatic symptom burden, which in turn is associated with higher levels of emotional exhaustion, turnover intention, and absenteeism. Results of a longitudinal analysis using data from four time points over 15 months supported these predictions. Taken together, this study advances the literature towards an understanding of the (potential) detrimental impact that need-thwarting work contexts can have on employee wellness and work-related outcomes.  相似文献

The investigation of the neural underpinnings of increased arithmetic complexity in children is essential for developing educational and therapeutic approaches and might provide novel measures to assess the effects of interventions. Although a few studies in adults and children have revealed the activation of bilateral brain regions during more complex calculations, little is known about children. We investigated 24 children undergoing one-digit and two-digit multiplication tasks while simultaneously recording functional near-infrared spectroscopy (fNIRS) and electroencephalography (EEG) data. FNIRS data indicated that one-digit multiplication was associated with brain activity in the left superior parietal lobule (SPL) and intraparietal sulcus (IPS) extending to the left motor area, and two-digit multiplication was associated with activity in bilateral SPL, IPS, middle frontal gyrus (MFG), left inferior parietal lobule (IPL), and motor areas. Oscillatory EEG data indicated theta increase and alpha decrease in parieto-occipital sites for both one-digit and two-digit multiplication. The contrast of two-digit versus one-digit multiplication yielded greater activity in right MFG and greater theta increase in frontocentral sites. Activation in frontal areas and theta band data jointly indicate additional domain-general cognitive control and working memory demands for heightened arithmetic complexity in children. The similarity in parietal activation between conditions suggests that children rely on domain-specific magnitude processing not only for two-digit but—in contrast to adults—also for one-digit multiplication problem solving. We conclude that in children, increased arithmetic complexity tested in an ecologically valid setting is associated with domain-general processes but not with alteration of domain-specific magnitude processing.  相似文献

This study presents the theoretical background, development, and psychometric properties of the German and English versions of the Experience in Personal Social Systems Questionnaire (EXIS.pers). It assesses how the members of a personal social system experience their situation within that system. It is designed as a research tool for interventions in which only one member of the system participates (e.g., Family Constellation Seminars). The EXIS.pers was created to measure change on the individual level relating to one's own important personal social system. In Study 1, we used exploratory factor analysis (EFA) for latent variable identification of the original German EXIS.pers (= 179). In Studies 2 and 3, we used confirmatory factor analysis (CFA) to examine the dimensionality of the German (= 634) and English (= 310) EXIS.pers. Internal consistencies and cross‐cultural structural equivalence were assessed. EFA indicated that a four‐factor model provided best fit for the German EXIS.pers. For both the German and English EXIS.pers, CFA provided the best fit for a five‐factor bi‐level model that included a general factor (Experience In Personal Social Systems) and four dimensions (Belonging, Autonomy, Accord, Confidence). Good internal consistencies, external associations, and cross‐cultural structural equivalence were demonstrated. This study provides first evidence for the German and English EXIS.pers as an economical and reliable measure of an individual's experience within his or her personal social systems.  相似文献

The present study examined whether prejudices towards Islam can be altered through corrective information. A total of 1715 German participants were first asked to appraise their opinions towards Judaism, Christianity and Islam (the ratings pertained to progressiveness, tolerance, peacefulness). Subsequently, questions regarding knowledge about religious topics were posed to participants. Questions were selected to elicit common prejudices pertaining to Islam. The correct answers were then displayed along with detailed explanations. Finally, participants were asked to rate their current opinion towards the three religions once again. Opinions towards Islam were largely negative at baseline but improved significantly after presentation of the correct answers. The present study suggests that prejudices against Islam are partially fueled by knowledge gaps.  相似文献

Although binegativity, the stigmatization of bisexuality, is prevalent among heterosexual and lesbian and gay communities, little research has addressed how the quantity and quality of intergroup contact affect binegativity. Drawing on intergroup contact theory, this study examined contact with and attitudes toward bisexuals among heterosexual undergraduates, heterosexual adults, and lesbians and gay men. Knowing more bisexuals (quantity) predicted more positive attitudes toward and decreased intergroup anxiety with male and female bisexuals. A multilevel structural equation model indicated that contact quality simultaneously predicted higher perceived stability of female bisexuality (but not male bisexuality) and tolerance of and less intergroup anxiety with male and female bisexuals when contact quantity was controlled for. This research suggests that both quantity and quality of contact with bisexuals predicts improved intergroup attitudes. Implications for future research on reducing binegativity are discussed.  相似文献
