It is often assumed creative performance is error free. Even a cursory inspection of eminent, creative, individuals indicates errors permeate creative efforts. In the present effort, the impact of error management on creative problem-solving is examined. Undergraduates, 136 in all, were asked to work through 10 potential problem solutions where half the solutions evidenced errors and half did not. Participants were asked to identify potential errors, deliberate on these errors, and remediate, or fix, errors prior to providing solutions to a problem calling for creative thought. It was found the number of errors correctly identified, and the quality of error remediation was positively related to the quality, originality, and elegance of problem solutions. More extensive deliberation, however, was found to be especially important for the production of original problem solutions. The implications of these observations for understanding the importance of error management in creative problem-solving are discussed. 相似文献

The purpose of this study was to explore how Buddhism is associated with well-being among Thai Buddhists via an application of stress process theory. Survey data were collected in 2012 from 314 Thai citizens and analysed with structural equation modelling to assess how the association between socio-economic status (SES) and well-being is mediated by stressors and resources, in particular, religious resources. The results reveal that low SES is associated with greater financial hardship and household crowding and lower sense of control, which in turn are associated with worse well-being. Furthermore, income is associated with happiness via belief in Dharma control, whereas education is associated with unhappiness via its negative association with public religiosity. Lastly, the positive influence of religious beliefs on well-being is contingent upon having a relatively high sense of control, whereas the positive influence of religious behaviours is contingent upon having a relatively low sense of control. 相似文献

Thirty-three adults with Down's syndrome (DS) originally tested by Woodruff-Pak, Papka, and Simon (1994) were retested approximately one year after initial testing as part of an ongoing longitudinal study. Subjects were tested in eyeblink classical conditioning (EBCC) and other neuropsychological tests. Adults with DS improved in EBCC over a 13-month period, but showed stability on other cognitive and behavioral tests. Age differences were found in EBCC but not other measures. Adults with DS aged 19-30 years performed significantly better in EBCC than adults with DS aged 46-65 years. Adults with DS aged 31-45 years did not show significantly different EBCC performance than subjects in older and younger age groups. the impaired EBCC performance of older adults with DS may be due to the presumed disruption of the hippocampal cholinergic system, which is an aspect of the Alzheimer-like neuropathology developing in adults with DS after the age of 35. the results further support the sensitivity of EBCC to Alzheimer-like neuropathology in older adults with DS. 相似文献

The authors investigated whether difficulties with temporal event coding, previously reported in patients with schizophrenia, are already present during first-episode psychosis (FEP). In this experiment, the subjective judgments of the simultaneity of visually presented stimuli were compared between 11 healthy controls, 9 patients with chronic schizophrenia (CSZ), and a sample of 11 FEP patients. Participants were asked to indicate whether 2 vertical bars appeared at the same time or at different times on a computer monitor. CSZ patients' thresholds were elevated, and the FEP sample showed higher thresholds relative to controls. Although preliminary, these findings indicate a generalized disturbance in event-structure coding at early stages of psychosis and question the specificity of its disturbance. Considering the proposed relationship between event-structure coding and the experience of time in general, this study recommends that future studies refocus on psychosis in general, rather than on schizophrenia as a particular case of abnormal temporal processing. In addition, it is suggested that the relevant psychopathology will be best determined by means of a comprehensive analysis of low-level temporal coding performance in different types of psychosis. 相似文献

Examinations of goal-directed movements reveal a process of control that operates to make adjustments on the basis of the expected visual afference associated with the limb's movement. This experiment examined the impact of perturbations to the perceived and actual velocity of aiming movements when each was presented alone or in tandem with the other. Perturbations to perceived velocity were achieved by translating the background over which aiming movements were performed. An aiming stylus that discharged air either in the direction of the movement or in the direction opposite the movement generated the actual velocity perturbations. Kinematic analyses of the aiming movements revealed that only the actual perturbation influenced the control of early movement trajectories. The results are discussed with respect to the influence that visual information has on the control exerted against physical perturbations. Speculations are raised regarding how potential for perturbations influences the strategies adopted for minimizing their impact. 相似文献

Smith and Farah (2011) provided a thought-provoking and perhaps deliberately provocative literature review of the use of stimulants to improve cognitive functioning in humans. They addressed the apparently increasing willingness of individuals mostly in the United States to use stimulants for this purpose and then summarized published literature that explores whether stimulants actually improve specific aspects of neurocognitive function. Although calling for more research, they tentatively concluded that stimulants indeed may be "smart pills" for some people under certain circumstances. This comment emphasizes that they never actually defined the desired qualities of a smart pill, seemed to accept the unproven axiom that slight improvements in specific tests constitute meaningful enhancement of intelligence, and failed to consider the possible costs to individuals and to society of promoting the use of this class of medications for such a purpose. 相似文献

In the present study, we examined adult age differences in short-term and working memory performance in middle-aged (45–64 years),
young–old (65–74 years), old–old (75–89 years), and oldest–old adults (90 years and over) in the Louisiana Healthy Aging Study.
Previous research suggests that measures of working memory are more sensitive to age effects than are simple tests of short-term
memory Bopp and Verhaeghen (Journal of Gerontology: Psychological Sciences 60:223–233, 2005), Myerson, Emery, White, and Hale, (Aging, Neuropsychology, and Cognition 10:20–27, 2003). To test this hypothesis, we examined output serial position curves of recall data from three span tasks: forward and backward
digit span and size judgment span. Participants’ recall patterns in the size judgment span task revealed that the two oldest
groups of adults showed the largest decreases in recall performance across output serial positions, but did not differ significantly
from each other. Correlation analyses indicated the strongest negative correlation with age occurred with the size judgment
span task. Implications of these findings for understanding strategic processing abilities in late life are discussed. 相似文献
