Fifty acute schizophrenics were given a multiple choice verbal concept formation test (Distractor Test). Included among erroneous responses which might be chosen by Ss were associatively linked distractors (ALD), word contiguity distractors (WCD) and rhyme or clang distractors (RD). It was found that most of the treatment effect was produced by the contrast between the number of ALD produced errors and the number resulting from WCDs and RDs combined. However, WCDs also produced significantly more errors than RDs.
