Document Summary
We are born vacant of all knowledge. A blank slate (not a fan of plato: classical conditioning: biological constraints. Ucr: vomiting: operant or instrumental conditioning skinner. Definition: process by which behaviours are instrumental in bringing about certain consequences . B. f. skinner positive vs. negative reinforcement punishment vs. extinction. Any behavior followed by a satisfying consequence is strengthened. Any behaviour followed by an annoying consequence is weakened. Puzzle box starved cat in box, cat finds lever quicker. A consequence of behaviour that increases the likelihood that the behaviour will occur again . Continuous reward is received after every correct response subject to rapid extinction. Partial reward is received after some correct responses. A behaviour which removes an aversive stimulus is more likely to occur in the future umbrella, coat, affiliation, bathroom break. A behaviour followed by no rewarding consequence will be weakened . Extinction is the key to eliminating troublesome behaviours but it"s harder to engineer and it takes longer.
