Document Summary

Shaping your dog to shake a paw. And maintained through operant conditioning (i. e. negative reinforcement) Escape conditioning learning a response to terminate an aversive stimulus (acquired and maintained through negative reinforcement) Avoidance conditioning learning a response to prevent the aversive stimulus from ever happening. *e. g. sam takes a turbulent flight and fear becomes paired with flying. *e. g. sam does not fly to minimize anxiety. Shaping reinforce successive approximations of the desired behavior. Dog sits then raises paw to chest height. Dog sits and places paw in your hand. Chaining reinforce each behavior in a sequence with the opportunity to produce the next response in the chain. Operant extinction decline in behavior due to lack of reinforcement. Fixed ratio reinforced after a fixed number of responses. Variable ratio reinforced after a variable number of responses. Fixed interval reinforced after a given amount of time has elapsed. Variable interval reinforced after a variable interval of time has elapsed.
