.— The effect on concept learning of the intra‐class variability of the relevant values of the instances was investigated. 20 subjects took part, and two ranges of the concerned intraclass variability, one about twice the other, were used. Depending upon the learning strategy used by the subjects the smaller intraclass variability was shown to have a limited facilitating effect on concept learning. Some facilitation thus occurred when strategies involved a rather unselective attention to the appearance characteristics of the instances but not when they involved selective focusing on these characteristics, or on elements of relevant knowledge established pre‐experimentally. The results were discussed in relation both to relevant S‐R‐conceptions and information processing models of concept learning. It was concluded that automatic generalization as described in S‐R‐theories might have to be integrated into the information processing models for some categories of learning.
