Cs predictive of the ucs. The initial learning is not lost, just inhibited. Reinforcement occurs when the consequences of an action increase the likelihood of the action being repeated. Reinforcement increases or strengthens the occurrence of a behaviour in the future: positive reinforcement: Ratio schedules: fixed ratio, variable ratio. Timing schedules: fixed interval, variable interval: partial reinforcement: Reinforcement is given only for some correct responses. Generates behaviour that persist longer: learners keep. Testing for a reward: fixed ratio schedule: Rewarded after a fixed number of correct responses. Faster responses yield quicker payoffs. Eg paid for producing a specific number of items: variable ratio schedule.
