The frequency of whistles and of diffuse vocalizations (chuts and chutters) of a single guinea-pig were recorded, in a domestic context, in the presence of food signaling stimuli. Whistles were elicited at a significantly higher rate by stimuli nearer the temporal the iminence of food. Diffuse vocalization increased, as whistles, with the occurrence of relevant stimuli, but only decreased when the animal was in contact with food. A further observation showed that vocalizations were emitted at a significantly higher rate in the presence of CS+ (a human caretaker who provided reinforcement) than in the presence of CS- (a human caretaker who did not). Results suggest that whistling and diffuse vocalizations are conditionable responses which varies in a non-monotonic way as a function of probability and temporal distance of reinforcement and which can be put under discrimination control using persons as stimuli.Downloads
