28 Parkinsonian patients matched with 28 normal controls took a free word-association test. Three variables were measured: the commonness of the responses, their latencies, and their repetitions. Comparison of the two samples showed the same magnitudes of intercorrelations among these variables. But, if commonness and latency remained the same, repetition increased significantly for patients. These data were discussed in relation to results on the absence of cognitive slowing.
