Document Summary
Positive reinforcement: increasing behaviors by presenting positive reinforcers. A positive reinforcer is any stimulus that, when presented after a response, strengthens the response. Negative reinforcement: increasing behaviors by stopping or reducing negative stimuli. A negative reinforcer is any stimulus that, when removed after a response, strengthens the response. (not a punishment) Primary reinforcer: an innately reinforcing stimulus, such as one that satisfies a bio need. Conditioned reinforcer: stimulus that gains its reinforcing power through its association with a primary reinforcer (also known as secondary) - money, good grades, nice voice. Reinforcement schedule: a pattern that defines how often a desired response will be reinforced. Continuous reinforcement: reinforcing the desired response every time it occurs. Partial (intermittent) reinforcement: reinforcing a response only part of the time; results in slower acquisition of a response but much greater resistance to extinction than does continuous reinforcement.
