A test was made of Amsel's extension of his hypothesis about the effects of nonreward, in which it is assumed that the gradient of stimulus generalization for avoidance elicited through anticipatory frustration is steeper than that for approach elicited through anticipatory reward. Sixteen rats were trained with 50 per cent reinforcement and 8 with 100 per cent reinforcement to run a straight alley. Eight of each set were shifted after 20 trials to an alley differing in brightness and the other 8 were shifted after 32 trials. The frustration effect (FE) was used as an index of the point at which to make the first shift, and the second shift was made at the stage used in experiments by Amsel. In neither case did the predicted boost occur with a shift during partial reinforcement, and the shift was less disruptive during continuous reinforcement, with no frustration. |
