An experiment investigated at what age children could represent movement in imagery. Five- and eight-year olds were asked whether two stimuli were the same or different in shape. The two stimuli were either presented in the same orientation or one stimulus differed from the other by clockwise rotation of 30 ° (0.52 rad), 60 ° (1.05 rad), 120 ° (2.09 rad), or 150 ° (2.62 rad). Children were instructed to visually imagine the counterclockwise rotation of one shape into the position of the other to help make the judgment. For both 5- and 8-yr olds, reaction times increased as a linear function of angular discrepancy between stimuli, indicating that both age groups represented rotation in their imagery. The findings conflict with Piaget and Inhelder's thesis that imagery representing movement first emerges when children are 7 to 8 yrs of age. 相似文献

An algorithm for clustering relational data with applications to social network analysis and comparison with multidimensional scaling 总被引:1,自引:0,他引:1
Ronald L Breiger Scott A Boorman Phipps Arabie 《Journal of mathematical psychology》1975,12(3):328-383
A method of hierarchical clustering for relational data is presented, which begins by forming a new square matrix of product-moment correlations between the columns (or rows) of the original data (represented as an n × m matrix). Iterative application of this simple procedure will in general converge to a matrix that may be permuted into the blocked form [?111?1]. This convergence property may be used as the basis of an algorithm (CONCOR) for hierarchical clustering. The CONCOR procedure is applied to several illustrative sets of social network data and is found to give results that are highly compatible with analyses and interpretations of the same data using the blockmodel approach of White (White, Boorman & Breiger, 1976). The results using CONCOR are then compared with results obtained using alternative methods of clustering and scaling (MDSCAL, INDSCAL, HICLUS, ADCLUS) on the same data sets. 相似文献

Several recent experiments are claimed to have tested conflicting predictions of cognitive dissonance and self-perception theories. It is argued that these claims fail to take into account the capacity of each formulation to account adequately for results “predicted” by the other. This argument is then continued, at a metatheoretical level, to reach the conclusion that the two theories are not capable of producing unequivocally contradictory predictions of cognitive consequences of experimental procedures. 相似文献

Multimethod factor scores were derived from measures of ACT aptitude, ACT nonacademic achievement and the Omnibus Personality Inventory. A sample of 89 subjects whose freshman major was engineering and whose junior year major consisted of a variety of nonengineering subjects represented subjects who had made an unrealistic vocational choice as freshmen. The junior year majors of these subjects were classified by Holland's theory of vocational choice and the relationship between the factor scores and Holland categories was shown by the technique of spatial configuration. These data were employed to illustrate how counseling practice could be integrated with vocational theory. 相似文献

Graduates from a public, postsecondary vocational-technical school are compared with a control group of individuals without such education in order to assess differences in level of anomie (via Srole Scale).While differences in some cases were minimal, vocational-technical graduates generally revealed a more positive attitude about the present and future. It is suggested that since their education is more job-centered, and they have already experienced some occupational “success”, they are more likely to have internalized and reflect traditional societal norms. The control group, while possessing similar demographic backgrounds, still are in transition-attending college, looking for work, etc. 相似文献

This study investigated the relationship between vocational interest as measured by the Vocational Preference Inventory and preferences of 175 undergraduates for structured or unstructured environments. Males having clear-cut preferences for structured situations had significantly higher Realistic-Conventional scores than those not having those preferences (p < .05). Additionally, males with structured preferences had significantly lower Social-Artistic scores (p < .025). Results for females were similar, but not statistically significant. Males also had significantly higher (p < .01) Realistic-Conventional scores than females. The significant relationships between VPI scores and preferences for structured and unstructured situations support Holland's contention that interest scores are expressions of personality needs. 相似文献

Recent concern for eliminating Strong Vocational Interest Blank (SVIB) sex bias has focused on the current use of separately normed Occupational Scales for the two sexes. This study implemented six basic methods of scale construction to examine the feasibility of combined-sex scales as well as advantages or disadvantages of modifications of current techniques designed to improve both single-sex and combined-sex scale construction. To study these six methods of scale construction, samples of male and female Ph.D. sociologists were collected. Concurrent validity and test-retest reliability data indicated that combined-sex scale construction for sociologists is possible if differences in female and male occupational interests, as measured by the SVIB, are treated as irrelevant variables in the world of work, and if concurrent validity is sacrificed. 相似文献

Four-month-old infants viewed two sound motion picture films of simple, natural events. The films were projected side by side, as one of the two sound tracks was played through a centrally placed speaker. Infants' visual attention to the films was consistently influenced by what they heard: They looked primarily at the event specified by the sound track. The experiment demonstrates that infants are able to perceive relations between sights and sounds in the absence of spatial cues. They respond to a perceived intermodal invariance with increased attention to the event reaching them over two modalities. 相似文献
