In brainstorming research, quantity is assumed to breed quality. However, little is known about the cognitive mechanisms underlying this relationship. A parsimonious explanation assumes a random process, in which every idea has an equal chance of being a high-quality (original and feasible) idea. In contrast, a ‘deep exploration’ approach suggests that the originality (but not the feasibility) of generated ideas is dependent on the degree to which people engage in deep exploration of their knowledge. We conducted two experiments to test the latter hypothesis. Prior to a brainstorming task, participants were primed with subcategories of the brainstorming topic. Priming caused a higher relative productivity and average originality within the primed subcategory, but did not affect global productivity and originality across categories. This effect was replicated in dyadic interactions. These results support the deep exploration hypothesis, and suggest that the relationship between quantity and quality is more complex than has previously been assumed. 相似文献

Involvement of industry in academic research is widespread and associated with favorable outcomes for industry. The objective
of this study was to review empirical data on the attitudes of researchers toward industry involvement and financial ties
in research. A review of the literature for quantitative data from surveys on the attitudes of researchers to financial ties
in research, reported in English, resulted in the 17 studies included. Review of these studies revealed that investigators
are concerned about the impact of financial ties on choice of research topic, research conduct and publication, but this concern
is less among investigators already involved with industry. Researchers approve of industry collaboration and financial ties
when the ties are indirectly related to the research, disclosure is upfront, and results and ideas are freely publicized.
However, their trust in disclosure as a way to manage conflicts may reveal a lack of awareness of the actual impact of financial
incentives on themselves and other researchers.

A sample of 128 highly religious (Christian) midlife American adults completed a series of attitudinal and personality trait measures and narrated 12 important autobiographical scenes in their life stories. Individuals high on self‐reported political conservatism tended to accentuate the theme of self‐regulation in their life stories, repeatedly describing important autobiographical scenes wherein they struggled to control, discipline, manage, restrain, protect, or preserve the self. By contrast, individuals high on political liberalism tended to emphasize the theme of self‐exploration, telling stories about expanding, discovering, articulating, or fulfilling the self. Demographics and dispositional traits (especially openness to experience) showed significant associations with conservatism‐liberalism, as well, but these variables did not mitigate the robust relationship between life‐narrative themes and political orientation. The results are discussed in terms of a broadened understanding of personality that conceives of dispositional traits and narrative identity as comprising distinct layers and complementary features of psychological individuality, both implicated in political lives. 相似文献

The nature of object-centred (allocentric) neglect and the possibility of dissociating it from egocentric (subject-centred) forms of neglect are controversial. Originally, allocentric neglect was described by and in patients who reproduced all the elements of a multi-object scene, but left unfinished the left side of one or more of them. More recently, however, Karnath, Mandler, and Clavagnier (2011) have claimed that the severity of allocentric neglect worsens when a complex ‘object’ shifts from an ipsilesional to a contralesional egocentric position. On the basis of these and of other clinical data, showing that allocentric and egocentric neglect are strongly associated, they have questioned the possibility of dissociating these two forms of neglect, suggesting that egocentric and allocentric neglect constitute different manifestations of the same disturbed system. Since these statements were inconsistent with the clinical findings which had prompted the construct of object-centred neglect, we checked in a group of right brain-damaged patients, who had copied the original multi-object scene, if the degree of neglect for the left side of figures varied as a function of their position on the horizontal axis. Furthermore, we reviewed all papers where copies of other multi-object scenes had been reported. Results of both studies failed to confirm the assumption of a relationship between spatial location of the stimulus and severity of object-centred neglect. This discrepancy between our data and those obtained by Karnath et al. (2011) could be due to the characteristics of stimuli and of procedures used to evaluate ‘object-centred’ neglect. If the stimulus is complex and the task requires its thorough exploration, the spatial location of the stimulus will influence the severity of ‘object-centred neglect’. If, on the contrary, the stimulus is simple and can be identified with few eye fixations, the spatial location of the stimulus should not influence the severity of ‘object-centred neglect’. In any case, our data confirm the possibility of dissociating allocentric from egocentric neglect. 相似文献

Personal identity formation represents a core developmental challenge for adolescents and young adults. Because much of the identity literature focuses on college students, it is necessary to conduct a detailed inquiry into the ways in which specific commitment and exploration processes develop over time for college students and for employed individuals. Two samples (456 college students and 318 employed individuals) were used to identify identity status trajectories over time and to examine external correlates of these trajectories (i.e. depressive symptoms, self‐esteem, identity centrality, community integration, and sense of adulthood). Similar identity trajectories emerged in both college students and employed individuals. Four of these trajectories corresponded to Marcia's identity statuses. In addition, apart from the ‘classical’ or troubled diffusion trajectory, a carefree diffusion trajectory was also obtained. Whereas individuals on an identity‐achieved pathway fared best in terms of the outcome measures, individuals in the troubled diffusion trajectory fared worst in terms of self‐esteem, depressive symptoms, and community integration over time. Implications and suggestions for future research are discussed. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

We tested a cross-sectional, moderated-mediation model of career identity in young adults (N = 667, 72.9% female, mean age = 20 years). In this model, career preparatory activities (career exploration and planning) were associated with perceptions of future employability and career distress. These relationships were mediated by career identity, and career identity was conditional upon level of career calling. We found that career exploration was associated with more career distress, while career planning was associated with less, and both career exploration and planning were associated with higher perceived employability. Career identity mediated between career exploration and planning and both outcomes, and these mediated relationships were stronger when career calling was higher. We interpreted the results from career construction, identity, and exploration perspectives; highlighted the applicability of these perspectives in the development of agency, career calling, and career identity; and made recommendations for testing other theory-based moderators. 相似文献
