The relationship between single‐word, free‐association response latency and the following characteristics of Kent‐Rosanoff words were examined: (a) grammatical form class, (b) emotionality, (c) familiarity, and (d)D(the number of different response words given to a stimulus word in a single‐word free‐association situation by a group of subjects). In addition was examined the relationship between response latency and (e) the type of associative linkage constituted by the stimulus‐response combination, and (f) response frequency. Given the limits posed by the present stimulus material, subject material, and analyses performed, the conclusion was reached that single‐word, free‐associative response latency is related primarily toD(r=0.81), secondly to the frequency with which a given stimulus‐response combination occurs in a
