Perceived exertion responses were compared between field-independent and field-dependent perceivers at three cycle-ergometer pedalling rates. 50 male subjects were classified according to mode of field approach on the basis of their performance on an embedded-figures test. Power output was held constant at 840 kpm/min., while pedalling rate was randomly set at 40, 60, or 80 rpm. Significant differences between the field-independent and -dependent groups were not found at the three pedalling rates for any of the physiological variables or for over-all, legs and chest ratings of perceived exertion. The extent of differentiated psychological functioning did not account for individual differences in perceptual reactance during muscular exertion. 相似文献

The generality of the levels of processing approach to memory was tested by using chess positions rather than words as stimuli. Experiment 1 compared recall following semantic orienting instructions (find the best move and determine which side has the advantage), formal orienting instructions (determine the number of pieces on light squares and the number of pieces on dark squares), and intentional learning instructions using 19 novice chess players as subjects. Formal orienting instructions produced poorer recall than did either semantic orienting or intentional learning instructions, which yielded similar levels of retention. These results were replicated in Experiment 2 with 16 tournament chess players. Chess rating correlated with recall .82 under semantic orienting instructions but only —.15 under formal orienting instructions. It was concluded that the levels of processing framework has applicability outside the area of verbal learning. 相似文献

In this note we investigate the condition that the distribution of the maximum of a set of random variables does not depend on which variable attains the maximum. This problem arises in random utility theory. When the random variables are independent, the property implies that all the marginal distributions must be Double Exponential (with distribution function exp(?e?x) in standard form). When dependence is allowed the property characrerizes a much broader class consisting of arbitrary functions of arbitrary homogeneous functions of the variables e?xi, a result stated without proof in D. J. Strauss (Journal of Mathematical Psychology, 1979, 20, 35–52). These are the distributions such that the maximum has the same distribution (apart from a location shift) as the marginals, provided the marginals are the same. 相似文献

The immediate impact on preschool and elementary school children of a televised presentation in which the traditional sex roles of physician and nurse were reversed was examined. After viewing a videotape of a male nurse and a female physician, subjects were asked to identify photographs or names of the physician and nurse. Preschool, first-, and fourth-grade children selected male names or pictures for the physician and female names or pictures for the nurse, thereby reversing genders. Their immediate recall appeared strongly influenced by their stereotypes rather than by the film they had just viewed. Seventh-grade children correctly identified the names of the physician and nurse.The authors wish to thank Dr. Edward F. Meydrech, Assistant Professor, Department of Preventive Medicine and Chief of the Division of Biostatistics, University of Mississippi Medical Center, for his invaluable assistance in the analysis of the data. 相似文献

Recent evidence from neuropsychology has proven useful in defining neural and cognitive subsystems involved in certain cognitive processes such as spatial attention (Posner, Walker, Friedrich, & Rafal, 1984) and imagery (Farah, 1988; Kosslyn, 1986). In this article we discuss neuropsychological evidence that suggests a modular system is responsible for the organization of parts and wholes by the visual system. We review both normal and neuropsychological evidence that suggest that hierarchical organization of objects within objects involves the coordination of at least four separate subsystems, one that emphasizes the global properties of a figure (association with right posterior superior temporal-parietal regions), one that emphasizes the local properties of a figure (associated with left posterior superior temporal-parietal regions), one that controls the distribution of attentional resources to these subsystems (associated with right or left lateral parietal lobe), and one that interconnects global and local properties and relies on the integrity of posterior temporal-temporal pathways. 相似文献

The Universal Declaration of Human Rights is a general legislative framework for democratic societies. Studying the social representations of these basic human rights helps to explain how people understand and assess the basic rights and how these rights relate to everyday life. Over 400 Czech university students rated the 30 articles of the Declaration of Human Rights on various scales (degree of understanding, personal relevance, consequences for individual responsibility, for government, political parties, etc.). A semantic space was identified in which concepts (i.e. the Articles of the Declaration) could be located. A typology (clusters) of articles was then established within that semantic space. A factor analysis of the scales resulted in a two-dimensional solution (‘positive attitude’ and ‘personal influence’). Five clusters of assessed articles were identified within this semantic space.
