Document Summary

Contiguity when 2 stimuli occur close together in time, they become associated. Pavlov believed 2 things about contiguity: for contiguity to occur the us and cs must be contiguous, if any us + cs are paired conditioning will occur (us) x-ray (cs) solution. Nausea (cr: (us) xray, (cs) water/lightness + xray. When something pleasant is added to the situation, and this increases the probability of the response reoccurring. Factors that influence the effectiveness of the sr2. One factor is the magnitude of the sr2. Second factor is the immediacy of the sr2. 4 main types of ratio and interval schedules. These are categories according to whether the criterion for reinforcing a response is the passage of time or the number of previous responses, and whether this criteria is fixed or variable. Reinforcement schedules: continuous reinforcement schedule (crf, intermitted or partial reinforcement schedules. Partial reinforcement schedule: produce more persistent behaviour. Ratio schedule sr+ depends upon the number of times behaviour occurs.
