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.

Prior stimulation and the perception of causality

An attempt was made to discover whether, in conditions similar to those of Michotte, the number of causal responses given by subjects was influenced by stimulation during the period just before the main experiment. Time-intervals between the arrival of object A and the departure of object B were systematically varied within the range 60 to 390 msec. Those who had earlier been exposed to shorter time-intervals (60 to 210 msec.) gave fewer causal responses than those who had been exposed to longer ones (150 to 300 msec. and 240 to 390 msec.). A possible explanation is offered in terms of the modification of existing “schemata.”
