An empirical verification of the Wherry-Gaylord iterative factor analysis procedure

A comparison of the Wherry-Gaylord iterative factor analysis procedure and the Thurstone multiple-group analysis of sub-tests shows that the two methods result in the same factors. The Wherry-Gaylord method has the advantage of giving factor loadings for items. The number of iterations needed can be reduced by doing a factor analysis of sub-tests, re-grouping sub-tests according to factors, and using each group as a starting point for iterations.

An exploratory study of word associations of Negro college students.

Two word-association lists of 50 words were each administered to 50 Negro college students. 41 words were taken from the Kent-Rosanoff list, 29 from the Palermo-Jenkins list, and 30 were words used in analogy items of the Scholastic Aptitude Test. Comparisons with previous normative studies showed generally similar results. The present study did result in slightly smaller proportions of matching from class primary responses to noun, pronoun, and adverb stimulus words and of opposite responses to “opposite-evoking stimuli.” A number of the responses indicated reading difficulty or misunderstanding of the word.
