The right hand hemisphere of the brain is purported to be the seat of the perceptual, intuitive, synthetic, visual and non-rational activities. In it is believed to reside the creative ability. Evidence is presented which suggests that, by exercising specifically the right hand hemisphere using a series of carefully structured tasks, some aspects of creative behaviour can be enhanced. It follows that users of creativity training courses should not expect every aspect of creative behaviour to be enhanced by any given course. 相似文献

Hardware is described that permits bidirectional transfer of data between the Commodore 64 and an IBM-compatible PC. Commercial terminal programs can be used to transmit data. The hardware, which can be constructed for less than $15, opens up several opportunities for making good use of the cost-effective C64 computer. 相似文献

An experiment was conducted to examine the contribution of sensory information to asymmetries in manual aiming. Movements were performed in four vision conditions. In the full-vision condition (FV), subjects were afforded vision of both the hand and the target throughout the course of the movement. In the ambient-illumination-off condition (AO), the room lights were extinguished at movement initiation, preventing vision of the moving limb. In the target-off (TO) condition, the target was extinguished upon initiation of the movement. In a no-vision (NV) condition, ambient illumination was removed and the target was extinguished upon initiation of the response movement. Results indicated that accuracy was superior in the full-vision and target-off conditions and when movements were made by the right hand. Movements made by the right hand were also of shorter mean duration. The magnitudes of performance asymmetries were uninfluenced by vision condition. Analyses of movement kinematics revealed that movements made in conditions in which there was vision of the limb exhibited a greater number of discrete modifications of the movement trajectory. On an individual-trial basis, no relationship existed between accuracy and the occurrence of discrete modifications. These data suggest that although vision greatly enhances accuracy, discrete modifications subserved by vision reflect the imposition of nonfunctional zero-order control processes upon continuous higher-order control regimes. 相似文献

NUMBER AND QUALITY OF ROLES 总被引:1,自引:0,他引:1
We used longitudinal personality data to test whether number and quality of roles were associated with health and self-enhancement in 100 privileged midlife women. Number of roles (from the set of partner, parent, and worker) was not related to autonomy, individuality, and complexity, as had been hypothesized, but to respect for norms, being well-organized considering oneselt like other people. Through women with one role were lower in well-being than women with more than one, hierarchical multiple regression showed no advantage to number of roles after psychological health at age 21 was taken in to account. However, quality of role, as assessed by marital satisfaction and status level in work, was associated with contentment and effective functioning, respectively, even after antecedent psychological functioning was taken into account. Particular roles were associated with particular advantages. The enhancement model of the accumulation of roles is compared with Erikson's theory of the development of personality. 相似文献

A new measure of hypersensitive narcissism was derived by correlating the items of H. A. Murray's (1938) Narcism Scale with an MMPI-based composite measure of covert narcissism. In three samples of college students (totalN= 403), 10 items formed a reliable measure: the Hypersensitive Narcissism Scale (HSNS). The new HSNS and the MMPI-based composite showed similar patterns of correlations with the Big Five Inventory, and both measures correlated near zero with the Narcissistic Personality Inventory, which assesses overt narcissism. Results support P. Wink's (1991) distinction between covert and overt narcissistic tendencies in the normal range of individual differences and suggest that it would be beneficial for personality researchers to measure both types of narcissism in future studies. 相似文献

Four experiments were conducted to examine the effects of periodic visual occlusion on one-handed ball catching. Tennis balls were projected one at a time over distances of 8-12 m, and liquid-crystal visual occlusion spectacles provided intermittent vision by opening and closing the lens shutters at different frequencies. As well as frequency, we manipulated duty cycle, or the proportion of time that the lenses were open. Generally, catching performance deteriorated as frequency was reduced. Although longer visual samples (i.e., increased duty cycle) mediated this effect to some extent, the most potent variable was the time between visual samples; performance deteriorated rapidly when this interval was greater than 80 ms (i.e., 10 Hz with 20-ms lens open times). Presumably this occurred because subjects had difficulty integrating visual information separated by longer temporal intervals. 相似文献

Perceiving geographical slant 总被引:1,自引:0,他引:1
Dennis R. Proffitt Mukul Bhalla Rich Gossweiler Jonathan Midgett 《Psychonomic bulletin & review》1995,2(4):409-428
People judged the inclination of hills viewed either out-of-doors or in a computer-simulated virtual environment. Angle judgments were obtained by having people (1) provide verbal estimates, (2) adjust a representation of the hill’s cross-section, and (3) adjust a tilt board with their unseen hand. Geographical slant was greatly overestimated according to the first two measures, but not the third. Apparent slant judgments conformed to ratio scales, thereby enhancing sensitivity to the small inclines that must actually be traversed in everyday experience. It is proposed that the perceived exaggeration of geographical slant preserves the relationship between distal inclination and people’s behavioral potential. Hills are harder to traverse as people become tired; hence, apparent slant increased with fatigue. Visually guided actions must be accommodated to the actual distal properties of the environment; consequently, the tilt board adjustments did not reflect apparent slant overestimations, nor were they influenced by fatigue. Consistent with the fact that steep hills are more difficult to descend than to ascend, these hills appeared steeper when viewed from the top. 相似文献

A series of studies investigated the capacity of children between the ages of 7 and 12 to give free and informed consent to participation in psychological research. Children were reasonably accurate in describing the purpose of studies, but many did not understand the possible benefits or especially the possible risks of participating. In several studies children's consent was not affected by the knowledge that their parents had given their permission or by the parents saying that they would not be upset if the children refused. In contrast, other studies found that children were much more likely to stop their participation if the experimenter said explicitly that she would not be upset if they stopped. We suggest that experimenters should pay more attention to describing the possible risks and benefits of participation in research, and that they should also make it clearer to children that they are free to stop once they have begun. 相似文献
