A recent report by the National Research Council (Huey & Wickens, 1993) has identified transitions in task demand as an important dimension for study in vigilance research. This experiment tested the possibility that the effects of such transitions follow a relatively simple psychophysical rule—they are characterized by contrast effects. Transitions in task demand were achieved by shifting subjects from single-task to dual-task monitoring and vice versa. These transitions produced changes in subjects' sensing and decision-making functions that were far more intricate than simple contrast effects. The demand transition issue offers a complex research challenge on both basic and applied levels and warrants further investigation. 相似文献

Reaching toward an object usually consists of a sequence of elemental actions. Using a reaching task sequence, the authors investigated how task elements of that sequence affected feedforward and feedback components of the reaching phase of the movement. Nine right-handed adults performed, with their dominant and nondominant hands, 4 tasks of different complexities: a simple reaching task; a reach-to-grasp task; a reach-to-grasp and lift object task; and a reach-to-grasp, lift, and place object task. Results showed that in the reach-to-grasp and lift object task more time was allocated to the feedforward component of the reach phase, while latency between the task elements decreased. We also found between-hand differences, supporting previous findings of increased efficiency of processing planning-related information in the preferred hand. The presence of task-related modifications supports the concept of contextual effects when planning a movement. 相似文献

Interpersonal dependency and locus of control orientation were studied in obese and nonobese samples. The Interpersonal Dependency Inventory (Hirschfeld, Klerman, Gough, Barrett, & Korchin, 1977) and the I-E Scale (Rotter, 1966) were administered to 106 obese adults in outpatient treatment for obesity. The I-E Scale was also administered to 97 nonobese control subjects. As predicted, the obese subjects were significantly more internally oriented than has been previously identified in obese populations. These findings challenge currently held assumptions about locus of control in obese groups. Although the obese and nonobese subjects maintained similar overall dependency scores, the obese subjects were more likely to show low levels of autonomy in comparison with the nonobese subjects. Interpersonal dependency and locus of control dimensions associated with obese conditions may serve as useful predictor variables influencing obesity treatment approaches and outcome. 相似文献

This study examined the role of suppressor effects on age differences in anxious emotion. Children and adolescents (n = 1099) ages 7–18 years were assessed for separation anxiety, social anxiety, and generalized anxiety. Results of zero-order correlations indicated a significant negative association between age and separation anxiety but no association for social anxiety and generalized anxiety. However, semi-partial correlations indicated the presence of a cooperative suppressor effect such that the associations between age and social anxiety as well as age and generalized anxiety symptoms became significant and positive and the association with separation anxiety became larger in a simultaneous regression analysis of each facet with age. Similar effects occurred when controlling for hyperarousal in an ANCOVA across grade levels. Results suggest that attempts to understand developmental differences in anxious emotion in childhood and adolescence will be facilitated by parsing facets of anxious emotion and attention to potential suppressor effects. 相似文献

Some theorists suggest that worry is elevated by positive beliefs when stressful events occur. Although several cross-sectional studies have revealed an association between positive beliefs and worry, few longitudinal studies have been conducted on this topic. Moreover, the effect of positive beliefs as a moderator on worry when stressful events occur has not been investigated. Against this background, the present study conducted a two-wave longitudinal survey to examine the moderating role of positive beliefs. One hundred and ninety-four college students voluntarily completed questionnaires. Hierarchical regression analysis showed a prospective relationship between the experience of stressful events and the subjective report of worry. Moreover, this relationship was moderated by an interaction with positive beliefs; stressful events were a stronger predictor of the extent of worry for individuals with a high level of positive beliefs than for those with a low level of positive beliefs. The moderating role of positive beliefs suggests that the level of positive beliefs amplifies the threat of worry caused by stressful events. 相似文献

The interview covers Rushton’s background in England, South Africa, and Canada, his education at the University of London (B.Sc., 1970; Ph.D., 1973), and his early research (1970–1980) on the social learning of generosity in 7- to 11-year olds. In his first book, Altruism, socialization, and society (1980), Rushton solved two “anomalies” for his social learning perspective—altruism in animals and traits in people—causing a “paradigm shift” for him toward sociobiology. He spent January to June 1981 at the University of California, Berkeley, to study the longitudinal stability of personality traits like altruism. There, he was influenced by Jensen’s work on g and race differences in rate of maturation and two-egg twinning. Subsequently, Rushton found that across 60 variables, Europeans fall between East Asians and Africans, closer to East Asians. He extrapolated Wilson’s (fast–slow) r-K life history theory to explain the pattern. Also covered is Rushton’s research on the heritability of altruism, and Genetic Similarity Theory explaining assortative mating and ethnic nepotism. Spouses and best friends are as similar as half-siblings and people randomly chosen from the same ethnic group are as related as first cousins. Altruism follows lines of similarity to replicate genes effectively. Rushton’s research on creativity is described. 相似文献

Because Western experiments assume creativity is an individual phenomenon and rarely investigate how trust and openness might build collective resonance, flow, and creativity, the creative whole typically amounts to less than the sum of the parts. The author argues, however, that group creativity increases as members develop, especially through Wilber's (in press) transpersonal stages. He illustrates how organizational leaders have facilitated creativity through reflective practice. Presenting evidence regarding the field effects of collective consciousness, he suggests that our minds and hearts interact in subtle yet powerful ways, which leaders can intuit, to support the emergence of collaborative creativity. 相似文献

It is possible to reveal and to examine the collective and social fields of consciousness experimentally. An account is given of planned experiments based on quantitative calculations, which indicate that the effects of individual and collective fields of consciousness on matter may elicit directly observable physical results. Moreover, it is shown that collective coherent consciousness fields may enhance the physical effects of consciousness at a significant rate. The predicted results have a significance in our picture of our consciousness, in self‐assertion and dynamising of consciousness, the expansion of collective fields of consciousness, and thus the raising of the level of consciousness for humanity. 相似文献

The authors discuss several surveys that cover the practices of psychoanalysts and psychotherapists in the Stockholm region. They compare these practices with other psychiatrists in both the private and the public sector. In addition, they discuss the results from an attempt towards continuous evaluation of psychoanalytical practices and their treatment standards including an evaluation of the development of individual psychoanalytical processes. 相似文献

Patterns of ratings using the Q-Sort method and the Likert-type method are compared. Ordering effects are found in Q-Sort ratings that are not present in Likert-type ratings. Specifically, item order is related to both item variance and item placement, such that items appearing near the end of the Q-Sort have less variance and more central placement. This finding is verified across three measures in several datasets spanning nearly 20 years of research. Such item order effects appear to attenuate average absolute relationships (covariances and correlations) between items appearing near the end of the Q-Sort and other measures. Randomization of items may be (in some situations) a viable course of action to minimize these effects at a sample level. 相似文献
