A Picture Story Test for eliciting narrative speech was administered to five patients in each of the subgroups of Broca's and Wernicke's aphasic subjects and matched controls. While Wernicke's subjects and normal-speaking subjects did not differ significantly in total output, the proportion of significant target lexemes was four times as great for normal-speaking subjects as for Wernicke's aphasic subjects. Broca's aphasic subjects, in spite of their telegraphic output, also had a smaller proportion of target lexemes than normal speakers. The proportion of nouns to verbs was elevated in the speech of Broca's aphasic subjects and depressed in the speech of Wernicke's aphasic subjects. Grammatical complexity was reduced in Wernicke's aphasic subjects, who used simple concatenation much more often than normal-speaking subjects. The Picture Story Test is suggested as a clinically useful technique.

An experiment is reported in which university undergraduates were given word definitions and asked to say aloud all responses that came to mind in the course of their attempts to retrieve the target words. Results showed that phonologically similar responses and word-fragments are good predictors of target word knowledge and the likelihood of eventual success in retrieval. Responses which were semantically related to the target word were less predictive of eventual success. Results are discussed in terms of their implications for interpreting tip-of-the-tongue analyses as a “window” on the process of word retrieval.
