Two 36-item lists composed of 12 adjectives, 12 nouns, and 12 verbs were presented either in random orders or by means of block presentation over 4 trials to determine whether form-class membership would constitute a basis for clustering. The individual words were not associated with one another. Under random presentation, no clustering was found, and, under block presentation clustering occurred in minimal amounts. Evidence was presented to indicate that Ss did not perceive or use form-class as a basis of organization, although classifications of the words according to form-class by comparable Ss were accurate. Whether unassociated but categorized words will cluster on the basis of their categories cannot be decided definitively from this experiment, but evidence is brought together which is suggestive of the notion that category relations may be ineffective as a basis for clustering in the absence of inter-item associations.
