Document Summary
Review: stimulus generalization: generalizing a response, refer to i>clicker, spontaneous recovery: having an extinguished response randomly kick in, extinction: over time he response to a stimulus goes away. I>clicker : nurse saying the needle wont hurt then stabs and your arm tenses, now when you hear it your arm tenses: classical conditioning. I>clicker: loud noise when you don"t buckle within 30 seconds, you become less likely to drive away without seatbelt: operant conditioning. Positive punishment ( decreasing behavior, adding stimulus. Reinforcement schedules: what kind of timeline are you reinforcing, either continuous or partial. Continuous: every time you do something you get something. Partial: sometimes getting something: ratio: behaviors, interval: time, fixed: predicable interval, interval: specific time, ratio, variable: not fixed interval of action, ratio: produces persistence of behavior, interval: not sure when. Shaping (operant conditioning technique: rewarding closer approximations to intended action, kindergarteners learning to write, writing on paper: reward, in relevant block: reward, writing within lines: reward.
