Subjects were selected as high or low in the number of primaries given in a word-association task under both standard instructions and with instructions to give popular associations. Low-commonality scorers produced words with a larger number of interconnexions than high-commonality scorers, but did not produce more different words on a later serial-association task. Commonality score under popular set did not seem to affect the production of associations. The associations of high-commonality subjects seemed to consist more frequently of the repetition of the original stimulus words and the original responses to those words as responses later in the task compared to low-commonality scorers.
