CHEMICAL TRANSFER OF ALTERNATION TRAINING IN THE SKINNER BOX

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.     

The Vocational Rehabilitation Counselor on Mental Patient Treatment Teams

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.

Effects of grammaticalness, presentation rate, and message length on auditory short-term memory

The aim of this study was to demonstrate the effect of message structure, message length, and presentation rate upon auditory short-term memory. Subjects were asked to reproduce in writing messages at different levels of “grammaticalness” (Coleman, 1965) presented through headphones at 3-4 words/sec. or 6-7 words/ sec. There was better recall of the more structured, shorter, and slower messages. The results are discussed in terms of acquisition and encoding of information.
