Relation of Divergent-Production Abilities to Verbal and Non-Verbal IQS
Guilford, J.P. (1975). Relation of Divergent-Production Abilities to Verbal and Non-Verbal IQS. The Journal of Multivariate Experimental Personality and Clinical Psychology, 1(4), 278-284.
Semantic, divergent-production (DP) tests have been known to correlate higher with IQS, and to show greater incidence of triangular scatter plots (some very low DP scores with IQS but no very high DP scores with low IQS) than do visual-figural tests. The two kinds of DP tests were studied in relation to both verbal and nonverbal IQS from the Lorge-Thorndike scale, Level III, with children. Only slight tendencies were found for stronger relationships between tests and IQS with similar contests--semantic and visual-figural. This result was attributed in part to lack of clear-cut distinction made by the two IQS and the possible higher-order factors cutting across the four kinds of tests.
