Subsequent Discrimination

Rats were pretrained in the presence of an auditory click rate stimulus of 14 pps correlated with variable-interval or variable-ratio reinforcement. During subsequent discrimination training, the added stimulus, correlated with extinction, was 18, 36, 72, or 0 (no sound) pps. After discrimination, Ss were given a generalization test session, in extinction, in which five click rate stimuli were presented. The inverse relationship between physical separation of the discrimination training stimuli and amount of peak shift of the generalization gradient occurred regardless of the original positive reinforcement schedule during training. Behavioral contrast was not produced by all Ss. Results demonstrated no effect of separation of training stimuli on behavioral contrast and that behavioral contrast and peak shift need not covary.

Significant Change

A passively elicited cortical potential that reflects the brain's discrimination of small acoustic contrasts was measured in response to two slightly different speech stimuli in adult human subjects. Behavioral training in the discrimination of those speech stimuli resulted in a significant change in the duration and magnitude of the cortical potential. The results demonstrate that listening training can change the neurophysiologic responses of the central auditory system to just-perceptible differences in speech.

Specific Learning

We investigated the formation of oddity concept in human subjects by means of multiple oddity discrimination tasks. Four human subjects were concurrently trained to discriminate an odd object from three identical objects in a row where the former one was reinforced. Discrimination tasks were gradually increased (e.g. 12 oddity tasks, 30 oddity tasks). Two out of four human subjects rapidly learned the acquisition tasks with higher accuracy rate suggesting that they seemed to avoid responding based on the strategy of the item-specific learning and to adopt relational processing. This assumption was stronger when robust transfer of learning with higher accuracy in baseline training performances was showed by them in transfer test 1 and transfer test 2. Although these findings offer evidence of relational oddity learning in humans, the possibility of the effect of stimulus generalization and the sense of perceptual oddity could not be excluded.
