The attribution of personality traits: the stutterer and nonstutterer.

Three videotaped recordings were made of an adult male speaking in an interview situation. Tapes differed as a function of the fluency exhibited by the interviewed speaker (i.e., fluent speech, primary stuttering, secondary stuttering). Three audiotapes were recorded from the videotapes yielding six stimulus tapes. Independent groups of college students saw and/or heard one of the stimulus tapes, each described as an interview with a "male who stutters." The fluent audio- and videotapes were replayed to two additional groups but were described only as an interview with a "male." Groups rated the personality of the speaker after tape presentation. Results revealed no difference in personality trait assignment as a function of experimental variables. However, in a second experiment two groups of college students rated a hypothetical normal speaker and hypothetical stutterer as significantly different in personality attributes. Results are discussed with reference to stereotyping behavior.
