ResumoPrevious work on concept identification has shown that misinformation feedback (MF) has a significant inhibiting effect upon performance (Pishkin, 1960). Restle (1957) has proposed a theory of discrimination learning wherein the proportion of relevant stimulus cues in a problem determines the rate of learning. The theory assumes a population of available stimuli consisting of sets of cues which are either irrelevant or relevant to the problem solution. Formally, 6 = r/r $ i, where r is the number of relevant cues, i is the number of irrelevant cues, and 6 is the learning rate. By assuming that over a series of trials, all irrelevant cues will be adapted nd thus rendered ineffective in determining S's responses, and that the probability of response is proportional ro the number of cues conditioned to it, Restle was somewhat successful in predicting the outcome of a variety of two-choice discrimination problems. According to Restle (1957), the rate of learning depends on Z-, which is the proportion of time a relevant cue is reinforced, and, therefore, the degree to which a cue is valid. Restle's cue validity (V) is represented by the following equation, Restle assumed that a relevant cue which is reinforced less than 100% of the trials has validity which will be less than unity. Therefore, Restle reasoned that the learning rate, e, is determined as follows.
