Three studies examined the nature of the contributions of each hemisphere to the processing of facial expressions and facial identity. A pair of faces, the members of which differed in either expression or identity, were presented to the right or left field. Subjects were required to compare the members of the pair to each other (experiments 1 and 2) or to a previously presented sample (experiment 3). The results revealed that both face and expression perception show an LVF superiority although the two tasks could be differentiated in terms of overall processing time and the interaction of laterality differences with sex. No clear-cut differences in laterality emerged for processing of positive and negative expressions. 相似文献

The evolution of the concept of “sleeper effects” is traced from the work of C. I. Hovland, A. A. Lumsdaine, and F. D. Sheffield, Experiments on Mass Communication. Princeton, N.J.: Princeton Univ. Press, 1949, to the present time. The concept originally referred to the delayed emergence of attitude change in persuasibility research. It has also been used in developmental investigations, with attendant theoretical problems that have not been fully addressed. These problems are examined, with the recommendation that the social psychologist's sleeper effect should be modified to meet developmental needs and renamed “delayed treatment effects”. Such effects are highly relevant to recent findings from studies of early childhood intervention programs. 相似文献

A sample of 1,877 high school seniors completed the Activities Index and High School Characteristics Index. The student responses were used to identify personality needs and environmental press differences across program and degree of program separation variables.It was concluded that: (1) College preparatory students perceived high personality needs for intellectual endeavors, while vocational students had needs for the tangible and concrete. (2) The personality differences across degrees of program separation suggested the physical proximity of the two program groups affected students' interpersonal relationships. (3) Several of the environmental press were exactly opposite the students' perceived personality needs. (4) The nonsignificant needs-press relationships suggested that high school environments were not facilitating the personality needs of students. (5) Comprehensive high schools seemed the most viable administrative configuration for servicing the diverse needs of today's high school students. 相似文献

The relation of identification preferences in college women to maternal work history and maternal career attitudes was examined, using direct, forced-choice questions concerning perceived similarity and desire to emulate (“pattern preference”) the mother or the father. It was expected that mothers who participated in work and desired a career would be more attractive models, compared to the father, than mothers who were not career-oriented. These expectations were based upon the assumption that role status, power, and satisfaction, which are important in identification motivation, are generally greater in working mothers. Findings tended to support this argument and were interpreted with the aid of subjects' explanations of their identification choices. 相似文献
