Rats’ responses to a moving object related to food or water: A behavior-systems analysis

摘要: The present experiments compared rats’ responses to a moving object (a rolling ball bearing) related either food or water under both Pavlovian and operant contingencies. In Experiment 1, food-restricted rats contacted food-related bearings more frequently with complex response patterns than water-restricted water-related bearings. Food-related contacts occurred shorter latency, longer average duration, increased likelihood of dig, carry, chew. 2 revealed that once contact the bearing had been established, its form persisted despite changes in type reward restriction. 3, were simultaneously restricted learned discriminate between painted unpainted versus no food, water, water. Again, produced complex, although not frequent, interactions did none lick results supported behavior-system approach, but stimulus-substitution arbitrary-operant accounts conditioned-response topography.
