Memory facilitation by posttrial hypothalamic stimulation and other reinforcers: A central theory of reinforcement

摘要: Abstract A central theory of reinforcement is presented, which based on the assumption that reinforcers act directly dynamic memory processes. One prediction from model learning various tasks should be improved as a result presented during period short-term memory. To test this hypothesis food, water or electrical stimulation lateral hypothalamus were posttrial in diverse situations. Posttrial food facilitated passive avoidance mice. In rats 30 sec reinforcing brain shuttle-box avoidance, step-down and small box avoidance. Appetitive T-maze was with contingent errors. Learning conditioned taste aversion not influenced by CS - UCS interval.
