THE EFFECTS OF REINFORCER MAGNITUDE ON TIMING IN RATS

摘要: The relation between reinforcer magnitude and timing behavior was studied using a peak procedure. Four rats received multiple consecutive sessions with both low high levels of brain stimulation reward (BSR). Rats paused longer had later start times during when their responses were reinforced low-magnitude BSR. When estimated by symmetric Gaussian function, also earlier; better-fitting asymmetric function or analyzing individual trials, however, these peak-time changes determined to reflect mixture large effects BSR on no effect stop times. These results pose significant dilemma for three major theories (SET, MTS, BeT), which all predict chronic manipulations magnitude. We conclude that increased influences in two ways: through larger immediate after-effects delay responding anticipatory elicit earlier responding.
