Abstract:To investigate how operant and alternative food arranged by different schedules interact to determine response rates and patterns when the sources of food are the same or different, six experiments were delineated. The effects of the number of food sources were investigated in Experiments 1-4. In Experiments 1 and 2, a variable-interval (VI) schedule was used to program the operant food, while the fixed-time (FT-Experiment 1) or the variable-time (VT-Experiment 2) alternative food was delivered from the same o… Show more
