The study examined the suitability of Furth's nonverbal conservation test as a psychometric tool for measuring individual differences in Zambia. The subjects included normal and mentally deficient Zambian children aged 7–13 years. The test was validated against age differentiation, differentiation of different intellectual levels, and school performance. The results showed that scores on the test increased significantly with increase in age, correlated positively and significantly with school scores, and differentiated normal from mentally deficient children. Within the normal sample the test also differentiated dull from average children; within the deficient sample the test did not differentiate the moderately mentally deficient from the severely mentally deficient. These results are explained by reference to the characteristics of the test, performance on which requires learning, memory, and perceptual abilities. 相似文献

A procedural theory of eye movement that accounts for main features of the stochastic behavior of eye-fixation durations and direction of movement of saccades in the process of solving arithmetic exercises of addition and subtraction is presented. The best-fitting distribution of fixation durations with a relatively simple theoretical justification consists of a mixture of an exponential distribution and the convolution of two exponential distributions. The eye movements themselves were found to approximate a random walk that fits rather closely in both adult and juvenile subjects the motion postulated by the normative algorithm ordinarily taught in schools. Certain structural features of addition and subtraction exercises, such as the number of columns, the presence or absence of a carry or a borrow, are well known to affect their difficulty. In this study, regressions on such structural variables were found to account for only a relatively small part of the variation in eye-fixation durations. 相似文献

F. W. Vondracek, R. M. Lerner, and J. E. Schulenberg (Journal of Vocational Behavior, 1983, 23, 179–202) criticize the vocational literature for failing to “follow acceptable scientific procedures for building a theory” and for failing to attend to important methodological and substantive developments. It is argued here that no single acceptable process for creating theory exists and three strategies useful for developing a theory are illustrated: immerse yourself in data, pick a specific set of results to explain, and try to resolve inconsistencies in the literature. Three criteria for evaluating theories and criticisms of them are discussed: comprehensiveness (content value), accuracy (truth value), and clarity (form). The paper by Vondracek et al. is examined from this perspective and is shown to lack the specificity, clarity, and accuracy necessary to be an effective guide to better vocational research or theory. 相似文献

An experiment was conducted to investigate an interpersonal process that contributes to the perpetuation of stereotyped beliefs about women and men. Male-female pairs of unacquainted individuals interacted to negotiate a division of labor on a series of work-like tasks (that differed in their sex-role connotations) in a situation that permitted control over the information that male perceivers received about the apparent sex of female targets. The perceivers' beliefs about the sex of their targets initiated a chain of events that resulted in targets providing behavioral confirmation for perceivers' beliefs about their sex. Targets believed by perceivers to be male chose tasks relatively masculine in nature, and targets believed by perceivers to be female chose tasks relatively feminine in nature. Although this behavioral confirmation effect was initially elicited as reactions to overtures made by perceivers, it persevered so that eventually targets came to initiate behaviors “appropriate” to the sex with which they had been labeled by perceivers. The specific roles of perceivers and targets in the behavioral confirmation process are examined. Implications of these findings for the perpetuation of stereotyped beliefs about the sexes are discussed. 相似文献

Discriminant analyses and stepwise multiple regression techniques were applied to teacher ratings of 184 kindergarten through eighth-grade students using Stephen's Social Behavior Assessment (SBA) inventory and were used to predict group membership as emotionalyy disabled (ED) or non-ED. The results suggested that the SBA was highly effective in correctly discriminating ED from non-ED students. The linear discriminant function derived from the 30 SBA subcategories correctly classified 83% of the subjects, yielding a highly significant separation of groups of ED and non-ED children. While the results of the discriminant analyses have not yet been cross-validated, these findings support the discriminant validity of the SBA for ED versus non-ED classification and suggest that the SBA is potentially a useful instrument for school psychologists as one source of information in a multifactored assessment regarding the identification of children as ED. 相似文献

In this series of experiments, evidence was found for a complex psychological representation of musical pitch. The results of a scaling study, in which subjects judged the similarities between pairs of tones presented in an explicitly tonal context, suggest that musical listeners extract a pattern of relationships among tones that is determined not only by pitch height and chroma, but also by membership in the major triad chord and the diatonic scale associated with the tonal system of the context. Multidimensional scaling of the similarity ratings gave a three-dimensional conical structure around which the tones were ordered according to pitch height. The major triad components formed a closely related cluster near the vertex of the cone; the remaining diatonic scale tones formed a less closely related subset farther from the vertex; and, the nondiatonic tones, still farther from the vertex, were widely dispersed. The results also suggest that, in the psychological representation, tones less closely related to the tonality are less stable than tones closely related to the tonality, and that the representation incorporates the tendency for unstable tones to move toward the more stable tones in time, reflecting the dynamic character of musical tones. In the similarity ratings of the scaling study, tones less related to the tonality were judged more similar to tones more related to the tonality than the reverse temporal order. Furthermore, in a delayed recognition task memory performance for nondiatonic tones was less accurate than for diatonic tones, and nondiatonic tones were more often confused with diatonic tones than diatonic tones were confused with nondiatonic tones. These results indicate the tonality-specific nature of the psychological representation and argue that the perception of music depends not only on psychoacoustic properties of the tones, but also on processes that relate the tones to one another through contact with a well-defined and complex psychological representation of musical pitch. 相似文献

Previous studies of children's performance on quantitative identity and equivalence conservation problems in the number domain are suggested to be flawed because of the low numbers of items in the arrays. In Experiment 1, children were tested on three different number versions of identity and equivalence conservation tasks. Their performance varied with the number of items and no child was found to pass a large number version of an equivalence conservation task and fail the corresponding version of an identity conservation task. In Experiment 2 the notion that the contextual effect of asking two similar questions might underlie the difference in performance on the two tasks was tested and rejected. The results are discussed in relation to recent analyses of conservation problems. 相似文献

Research on context effects in impression formation has taken the form of testing competing predictions from the averaging model and the meaning shift model. This between-theory conflict has been unprofitable because neither theory has yet acquired the degree of specificity necessary to generate unequivocal predictions in this area. The research has been useful, however, in identifying each theory's capacity to generate self-contradictory predictions. Future research on this topic can most profitably be addressed to resolving these within-theory conflicts. 相似文献

公民的两种身份及其道德要求 总被引:1,自引:0,他引:1
“公民道德”意义上的公民具有两种身份,一是法律身份,一是社会身份。不同的身份决定了对个体不同的道德要求。一般来说,这两种身份统一于一个具有完全责任能力的个体之中,不同的身份只能出现在不同的场合或者承载不同的社会关系,场合不同、社会关系不同,对他的道德要求就不一样,二者不能混淆,即身份是不能僭越也不能放弃。但是,两种身份的道德要求在底线上是一致,这就是说,两种身份的责任和道德要求在特定的场合和社会关系之中可以融通。 相似文献

自尊与人际互动:理论、研究与问题 总被引:1,自引:0,他引:1
基于自我确认理论开展的大量研究,有助于理解自尊对人际互动行为的调节作用。然而,研究者对自尊的测量工具不尽相同,筛选实验被试的标准也不尽一致,实验范式忽略了对实际人际互动情境的操纵,单纯采用人际选择反应作为测量自我确认的指标,因而难以形成具有整合性的理论模型。今后的研究有必要在编制合适的测量工具的基础上,将整体自尊与特殊自尊作为两个独立的变量置于整合性实验范式下开展研究,同时采用对人际评价信息的认知判断和对评价者的交往选择的双维指标,以全面揭示整体自尊与特殊自尊对自我确认过程的相对作用及其心理机制。 相似文献
