Vocal conditioning in the guinea pig

Abstract

Two male guinea pigs were trained to vocalize for ICS reinforcement. Ss were differentially reinforced for calls in the 1000–2000 cps audio frequency range. When this vocal behavior was stabilized, reinforcement was made contingent on calls in the 2000–4000 cps range. Reinforcement of the 2000–4000 cps calls resulted in an increased proportion of calls in this range and a decreased proportion of calls in the 1000–2000 cps range. Sonograms of the calls under the two conditions showed the development of different sonic patterns. © 1967, Psychonomic Press. All rights reserved.
