The present study tests the hypothesis that attention-switching is time-consuming and performance-limiting. Analysis of previous research on counting interaurally presented clicks shows that estimates of ‘switch-times’ can be made, based on the data of Guzy and Axelrod (1972). In the earlier click-counting studies, however, the number of clicks to be counted and the number of physical switches between the ears were confouned. Hence the number of clicks, number of physical switches and interval between clicks were independently varied. The results showed that (a) counting performance did not decrease monotonically with increasing number of switches in the click sequence; (b) no difference in counting performance could be found between the monaural and completely alternating interaural presentation; (c) when the number of switches in the sequence was small and equal groups of clicks alternated between ears, performance dramatically improved. With these kinds of sequences, subjects presumably do not count the clicks one at a time, but subitize a group of clicks. 相似文献

Effect of peer presence on the sex-typed toy choices of 3- and 4-year-olds was investigated in a repeated measures experimental design. Twenty-six girls and thirty-six boys were tested under three conditions: (a) alone; (b) in the presence of a same-sex peer; and (c) in the presence of an opposite-sex peer. Amount of time spent playing with three feminine- and three masculine-stereotyped toys was recorded. For both boys and girls, play with “sex role-inappropriate” toys was significantly lower in the presence of an opposite-sex peer than in the solitary condition. Across conditions boys exhibited less play with opposite-sex-typed toys than girls. Rate of play with opposite-sex-typed toys increased in successive trials for both sexes. These results indicate that the presence of an opposite-sex peer functions as a discriminative stimulus for avoidance of “sex role-inappropriate” play in preschoolers and suggests that preschoolers may have a history of differential reinforcement for sex-typed play in the presence of peers. 相似文献

The construct of general intelligence is discussed in a number of different contexts. The fundamental empirical basis for it is the positive trend among the smallest correlations among cognitive measures. Differences among factor models which recognize this in different ways are discussed. Evidence for the general factor in intelligence is also found in the difficulty in finding evidence for differential validity of tests from one criterion to another. Performance on Piagetian tasks reflects mainly general intelligence. Individual differences in aural comprehension of language anticipate later individual differences in intellectual development. Selective forces which produce differences among schools operate largely on the general factor. To the extent that there is a genetic contribution to individual differences on cognitive tests, it appears to be to the general factor variance. Social class differences among whites appear to be largely on the general factor, but black-white differences require other dimensions. Although the general factor is, in a sense, real, it is not interpreted as an entity within the organism. Instead it is an abstraction resulting from the many genes, the many environmental pressures, and the many neural structures involved in the wide variety of human behaviors which can be labelled cognitive or intellectual. 相似文献

Left and right hemisphere processing capabilities for pictorial information about agent (performer of an action) and patient (recipient of an action) relations were assessed in a tachistoscopic study. Subjects were presented pictures in either the right or the left visual field depicting an agent-action-patient event. They were asked to locate which side of the drawing contained the agent and, in separate trials, which side contained the patient. Reaction times to locate the agent were significantly faster than to locate the patient, regardless of the field of presentation. The results are discussed in terms of a general nonlinguistic processing constraint that favors agent information. It is suggested that this processing asymmetry may underlie syntactic asymmetries regarding the expression of agents and patients in language. 相似文献

A two-wave analysis of the dynamics of occupational expectations in a rural youth panel generally failed to support the hypothesis of ‘increasing realism of choice.’ An analysis of four multiple regression equations indicated (1) that Black youth tended to lower their levels of occupational expectations over time and (2) that occupational expectations tended to vary with changes in occupational aspirations and educational expectations. However, family SEI, perception of occupational goal blockage, three measures of self image and change in perception of occupational goal blockage, were not found to be associated with the dynamics of occupational expectation. Two alternate explanations for the findings were presented. 相似文献

The article gives an overview of Simmel's thought on happiness between the 1890s and 1918. The focus is on the effects of Simmel's general orientation towards the Lebensphilosophie, especially via his reception of Nietzsche. Throughout his writings Simmel displays a distance against traditional views of happiness as an aim of action. Within the framework of Lebensphilosophie happiness becomes a quality of essentially lived life (or, following Nietzsche, heightened life). As a consequence, Simmel's concept of happiness tends to emphasize connotations of felicity, and can therefore be interpreted as a modern, secularized variant of traditional beatitudo. 相似文献

The intersection of the lives of 2 essential individuals in science, behavior analyst Murray Sidman (1923-2019), and Henry G. Molaison also known as Patient H.M. (1926-2008), warrants examination as it highlights the role of behavior analysis and other disciplines in the emergence of modern neuroscience and a collaborative approach to science. This paper describes the historical context and content of two publications by Sidman in which Molaison served as a research participant. The goal of the present paper is to emphasize this little-known facet of Sidman's rich career and to highlight the pioneering role of behavior analysis, and particularly the work of Murray Sidman, in the emergence of collaborative modern neuroscience. 相似文献

Georges Perec's book La Boutique Obscure (1973; translated into English in 2012) serves as the basis for this paper. The book is a collection of dreams that its author dreamed from May 1968 to August 1972. The present author treats these dreams as chapters in a bizarre autobiography, elaborating Perec's life through a discussion of those dreams and using them as a starting point with which to discuss his views of dream interpretation and the role of dreams in psychoanalysis. 相似文献
