摘要:
In a previous study, we demonstrated that the pitch of a complex tone could be changed and maintained in the direction of another complex tone with which it had been associated. Questions in the present study were whether the pitch change would generalize to the nonconditioned ear and to other similar tones. Information was also desired on possible long‐term characteristics of the pitch change. Experimental stimuli were pitch‐shift tones of 1150‐1350‐1550‐1750 and 1250,‐1450‐1650‐1850 Hz. Each was used with different subjects to test both up and down pitch changes. These tones are normally judged to have pitches of about 190 and 210 Hz, respectively. The conditioning tone was the first five harmonics of fundamental 200 Hz. To establish the pitch change, this tone and one of the pitch‐shift tones were heard together for 30 min each day for 5 nonconsecutive days. The results indicated that the average pitch change of about 8 Hz: (1) generalized to the nontest ear after being initially ear specific, (2) generalized more readily to higher rather than lower tones relative to the conditioned tone, and (3) was still maintained at approximately 3 mo after the conditioning sessions.
