designed the operant chamber, which has a bar that an animal presses to release a reward, with a device that records responses; proved rewarded behavior is likely to recur
any event that strengthens the behavior it follows
increasing behaviors by presenting positive stimuli, such as food; strengthens the response
increasing behaviors by stopping or reducing negative stimuli; when removed after a response, it strengthens the response
an innately reinforcing stimulus, such as one that satisfies a biological need
conditioned reinforcer; a stimulus that gains its reinforcing power through its association with a primary reinforcer
a reinforcement schedule that reinforces a response only after a specified number of responses
a reinforcement schedule that reinforces a response after an unpredictable umber of responses
a reinforcement schedule that reinforces a response only after a specified time has elapsed
a reinforcement schedule that reinforces a response at unpredictable time intervals
any consequence that decreases the frequency of a preceding behavior
adds something unpleasant
takes away something pleasant
reinforcers guide behavior toward closer and closer approximations of desired behavior
learn by observing others
process of observing and imitating a specific behavior
similar to Pavlov; conscious/unconscious didn't matter in learning
