With two unique sets of random shapes as stimuli, one set for relevant, the other for irrelevant verbal pretraining, and with specially scaled concrete nouns as verbal responses, an experiment was designed as a possible check on Gibson's hypothesis concerning generalization among stimuli in paired-associates learning. Performance on the Star Discrimeter followed verbal pretraining. The errors made on the Star by one of the experimental groups, compared with the errors made by its control, lent some support for the hypothesis; but additional experimentation is needed.
