Virginia Opossum

Laboratory-raised Virginia opossum have been found to readily acquire a lever-press response for water reinforcement. Fixed ratio behavior is comparable to that observed in other species. Fixed interval behavior, however, tends to move fairly rapidly toward an economical response style in which very few responses are emitted per reinforcement. Neither introduction of limited hold procedures nor lengthening of the deprivation schedule had any effect upon the FI responding.

Probe Test

Rats received discrimination training, wherein the S+ was a light-on (100 ft-c) and the S— was a light-off (0 ft-c). The schedules of reinforcement during S+ were a fixed-interval 30-sec. schedule with a limited hold of 5-sec. for two rats and a variable interval 30-sec. schedule for 3 Ss. After discrimination performance had stabilized, a probe-testing technique was used to test for generalization to three logarithmically arranged test stimuli (1, 25, and 50 ft-c). Tests were conducted with 5- and 2-day intertest intervals. The results indicated no difference in gradient shape after testing with 5- or 2-day intertest intervals. It was concluded that repeated probe testing for generalization virtually eliminates cumulative extinction effects that may distort gradient shapes.

Equivalence Class Formation

AbstractIn an attempt to limit the opportunity to engage in mediating behavior, two groups of adult participants received preliminary training in identity matching with limited hold levels (LH) for responding of 0.7 s for the sample and 1.2 s for the comparisons. The two groups were subsequently trained to form three 5-member classes, using the same LH levels, where the A, B, D, and E stimuli were abstract stimuli, and the C stimuli were meaningful pictures. In two tests for emergent relations, the LH for Group Short was unchanged, whereas 5 s were added to the LH for the comparisons for Group Long. None of the participants in Group Short responded in accordance with stimulus equivalence in either of the two tests. In Group Long, one participant responded in accordance with stimulus equivalence in the first test, and an additional eight participants formed equivalence classes in the second test.

Conductance Changes

The performances of mental patients and normals were compared on a monitoring task using the Holland procedure for measurement of observing responses. Subjects were required to rapidly detect and react to signals which occurred at 2-min. intervals with a 15-sec. limited-hold. Some patients performed effectively in terms of detecting and reporting signals; however, the temporal pattern of observing responses within fixed-intervals differed in varying degrees from the extended post-target pauses and high terminal rate of the normals. Later sessions with modifications in the procedure showed the following: some patients could not maintain a high detection rate with a very brief limited-hold; a warning light during the latter part of each 2-min. interval controlled the observing responses of some patients; regular changes in local rate by some patients occurred during an extinction period; and the temporal characteristics of responding by patients and normals were more similar under a variable-interval schedule of signals. The intra-interval pattern of skin conductance changes during the monitoring session did not show any gross characteristic which differentiated the patients from the normals.
