In recent years, scholars have empirically demonstrated that creativity can be described as radical or incremental creativity. In efforts to better understand the nomological networks underlying radical and incremental creativity, this study explored the role that positive emotions directly and indirectly plays in predicting each type of creativity. Further, whether the nature of these mediated relationships varied differentially as a function of employees’ tendency to also engage in such purposeful activities as monitoring their creative behaviors and deepening their expertise was also explored. The resultant moderated-mediation model was tested in a field study of 129 professional employees in a large North American consumer products organization. Results indicated that positive emotions influence incremental and radical creativity differentially through fun, and that the degree to which individuals engage in monitoring impacts their levels of creativity. Implications and future directions for research and practitioners are discussed. 相似文献

The present study examined the validity of a self-report parenting instrument for use with Mexican adolescents. The 13-item measure was adapted from the Mexican Parenting Questionnaire. The sample included 1123 adolescents (M age?=?15.07, SD?=?1.52) from Puebla, Mexico. Adolescents self-reported on six subscales of parenting (i.e., affection, verbal guidance, monitoring, communication, physical punishment and verbal punishment), as well as on measures of school grades, life satisfaction, familism, depressive and anxiety symptoms. Using confirmatory factor analyses, the original constructs were found to be a good fit with the data. Most subscales consisted of moderate levels of internal consistency and predicted several measures of adolescent adjustment in expected directions. Girls were more likely to report higher levels of monitoring, affection, and communication than boys. Adolescents who were younger and who reported lower school grades were more likely to report greater levels of physical punishment. Familism was positively associated with five of the six parenting dimensions (i.e., affection, verbal guidance, monitoring, physical punishment, and communication). Findings advance understanding on families and adolescent well-being in Mexico and may inform culturally competent services for clinicians who work with Mexican families. 相似文献

Those who favour an ontology based on dispositions are thereby able to provide a dispositional essentialist account of the laws of nature. In part 1 of this paper I sketch the dispositional essentialist conception of properties and the concomitant account of laws. In part 2, I characterise various claims about the modal character of properties that fall under the heading ‘quidditism’ and which are consequences of the categoricalist view of properties, which is the alternative to the dispositional essentialist view. I argue that quidditism should be rejected. In part 3, I address a criticism of a strong dispositional essentialist view, viz. that ‘structural’ (i.e. geometrical, numerical, spatial and temporal) properties must be regarded as categorical. 相似文献

The purpose of this quasi-experimental study was to investigate what appears to be a grounding assumption in some adult developmental and educational research: persons of differing epistemologies who are grouped together will understand one another less well than persons who are grouped homogeneously. A robust effect is discussed within the context of adult development theory, research on collaborative learning groups, and Bruffee's social constructionist challenge (K. A. Bruffee, 1993) to Perry and to cognitive development theory. Collateral research questions relating to covariates of developmental position (according to the Perry scheme) are entertained; confirmatory qualitative data are presented. 相似文献

Suicidal behavior is a potentially lethal complication of late-life depression. In younger adults, suicide has been linked to abnormal decision-making ability. Given that there are substantial age-related decreases in decision-making ability, and that older adults experience environmental stressors that require effective decision-making, we reasoned that impaired decision-making may be particularly relevant to suicidal behavior in the elderly. We thus compared performance on a probabilistic decision-making task that does not involve working memory ("Cambridge Gamble Task") in four groups of older adults: (1) individuals with major depression and a history of suicide attempt (n = 25), (2) individuals with major depression with active suicidal ideation but no suicide attempt (n = 13), (3) individuals with major depression without suicidality (n = 35), and (4) nondepressed control subjects (n = 22). There was a significant effect of group on quality of decision-making, whereby the suicide attempters exhibited poorer ability to choose the likely outcome, compared with the nonsuicidal depressed and nondepressed comparison subjects. There were no group differences in betting behavior. The suicide attempters differed in several aspects of social problem-solving on a self-report scale. Quality of decision-making was negatively correlated with the score on the impulsive/careless problem-solving subscale. These data suggest that older suicide attempters have a deficit in risk-sensitive decision-making, extending observations in younger adults. More specifically, older suicide attempters seem to neglect outcome probability and make poor choices. These impairments may precipitate and perpetuate suicidal crisis in depressed elders. Identification of decision-making impairment in suicidal elders may help with designing effective interventions. 相似文献

Learning, attentional, and perseverative deficits are characteristic of cognitive aging. In this study, genetically diverse CD-1 mice underwent longitudinal training in a task asserted to tax working memory capacity and its dependence on selective attention. Beginning at 3 mo of age, animals were trained for 12 d to perform in a dual radial-arm maze task that required the mice to remember and operate on two sets of overlapping guidance (spatial) cues. As previously reported, this training resulted in an immediate (at 4 mo of age) improvement in the animals' aggregate performance across a battery of five learning tasks. Subsequently, these animals received an additional 3 d of working memory training at 3-wk intervals for 15 mo (totaling 66 training sessions), and at 18 mo of age were assessed on a selective attention task, a second set of learning tasks, and variations of those tasks that required the animals to modify the previously learned response. Both attentional and learning abilities (on passive avoidance, active avoidance, and reinforced alternation tasks) were impaired in aged animals that had not received working memory training. Likewise, these aged animals exhibited consistent deficits when required to modify a previously instantiated learned response (in reinforced alternation, active avoidance, and spatial water maze). In contrast, these attentional, learning, and perseverative deficits were attenuated in aged animals that had undergone lifelong working memory exercise. These results suggest that general impairments of learning, attention, and cognitive flexibility may be mitigated by a cognitive exercise regimen that requires chronic attentional engagement. 相似文献

Tool use is of great interest for cognitive research, largely because it can be particularly revealing about the underlying
information processing mechanisms. Tool use that is inflexible or requires extensive experience to change, and that is only
addressed towards specific targets such as food, is not likely to reflect unusual or particularly complex cognition. On the
contrary, if tools are employed flexibly and for a variety of innovative purposes, then conventional combinations of inherited
predispositions and associative learning are challenged and interesting questions emerge. Since New Caledonian crows (Corvus moneduloides) are especially adept at using and making tools for food extraction, we decided to examine their ability to generalise this
to other contexts. We recorded how five pairs of New Caledonian crows interacted with novel objects that were not associated
with food. We observed eight occasions in which the first contact with the novel object was mediated by a tool, suggesting
that the function of the tool was for exploration. This is the first report of non-foraging tool use in New Caledonian crows,
and it implies that the cognitive operations controlling tool-oriented behaviour in this species are more general than previously
thought. 相似文献
