55 student volunteers listened to 8 words each played for 3 min. (73 repetitions) and, as instructed, reported illusory changes heard. Scores on the Barber Suggestibility Scale correlated significantly (rho = .34) with the number of times subjects alternated between hearing different forms (perceptual organizations) but not with the number of different forms reported. Differences in the ability to concentrate on subjective experiences associated with suggestibility are proposed to account for the relationship. It is suggested that hearing different forms and alternating between them may depend on different mechanisms.
