Time scores were obtained from five groups of subjects, ranging in average age from 8 yr. to 62 yr., on six types of concept‐attainment problem presented in familiar and unfamiliar symbols. The results for each group were subjected to analysis of variance. The effects of size of problem and type of symbol employed were highly significant irrespective of age. The effect of type of problem (presenting positive or mixed instances) was significant in all but the 62 yr. group, and the interaction between type and size of problem in all but the 38 and 62 yr. groups. The interaction between type of problem and type of symbol employed was, however, significant only in the 38 and the 62 yr. groups. An interpretation is suggested for these differences. In the three adult groups, problem‐solving proficiency was shown to correlate with short‐term memory capacity for the familiar and unfamiliar symbols employed.
