F jerdingstad , E. J. Chemical transfer of alternation training in the Skinner box. Scand. J. Psychol ., 1969, 10 , 220–224.—In six individual experiments one group of recipient mice was injected with brain extract from rat donors trained to alternate between bars in a Skinner box; another group was injected with extract from donors reinforced for pressing either bar irrespective of choice. During testing the recipients of 'alternation extract' showed a significantly higher tendency to alternate.  相似文献

This study asked the question: What are the role expectancies of treatment personnel in the treatment community and are they consistent across patients' emotional condition? An 83-item inventory was developed and administered under three different sets of instructions, each characterizing a different patient condition. Treatment staff and administrators were asked to rate items on the basis of the level of expectancy they held for their team vocational rehabilitation counselor. The analyses suggest that treatment staff and counselors do not agree on role expectations and that patient condition is a significant mediating variable.  相似文献

A direct test was performed of Oldfield's (1966) derivation of the relationship between naming response latency and memory ensemble size. The results confirmed Oldfield in every particular. Further, the results support Sperling's (1967) suggestion of a recognition buffer-memory mechanism between the initial stimulus-encoding stage and the long-term memory stage of human information processing.  相似文献

This investigation focused on the differences in reported personal adjustment problems between freshmen students who made a congruent college major choice and students who made an incongruent choice. Personal adjustment was defined operationally with the Mooney Problem Checklist. Congruent and incongruent college major choice groups were defined operationally using the Vocational Preference Inventory. In the analysis of variance of the adjustment scores, the interaction term involving congruence of major choice and sex and the test for the main effect of sex were not significant. The test for the main effect of congruence was found to be significant. Subjects who had made a congruent college major choice reported fewer personal adjustment problems when compared to subjects in the incongruent group.  相似文献
