Document Summary
Operant conditioning - organisms associate their behaviors with consequences. Behaviors followed by desirable consequences increase in frequency. Behaviors followed by undesirable consequences decrease in frequency. Committed to finding ways to objectively measure behavior. Highly influenced by pavlov, though his work resembled thorndike"s. Both involve acquisition, extinction, spontaneous recovery, generalization, Behavior that occurs as an automatic response to some stimulus in the discrimination environment. Operant conditioning involves operant behavior behavior that operates on the environment, producing consequences. Reinforcer any event that strengthens, or increases the frequency of, a preceding response. Positive reinforcer a stimulus presented after a response, causing an increase in the rate of response. (ex: reward, praise, attention) Negative reinforcer a stimulus that causes an increase in the rate of response, but works by removing that stimulus (e. g. car seatbelt sound) Timing between response and reinforcement is very important! The behavior that is strengthened is the one that occurs just before the reinforcer is presented.
