reinforcement

 [re″in-fors´ment]
the increasing of force or strength. In the psychological theory of behaviorism, presentation of a stimulus following a response that increases the frequency of subsequent responses. This is central in operant conditioning.



Positive reinforcement consists of a stimulus that is added to the environment immediately after the desired response has been exhibited. It serves to strengthen the response, that is, to increase the likelihood of its occurring again. Examples of such reinforcement are food, money, a special privilege, or some other reward that is satisfying to the subject.

Negative reinforcement consists of a stimulus that is withdrawn (subtracted) from the environment immediately after the response, so that the withdrawal serves to strengthen the response.
reinforcement of reflex strengthening of a reflex response by the patient's performance of some unrelated action during elicitation of the reflex.

2. In dentistry, a structural addition or inclusion used to give additional strength in function; for example, bars in plastic denture base.

3. In conditioning, the totality of the process in which the conditioned stimulus is followed by presentation of the unconditioned stimulus, which itself elicits the response to be conditioned.

reinforcement

A term used in learning theory and in behaviour therapy that refers to the strengthening of a tendency to respond to particular stimuli in particular ways. In classical conditioning, the occurrence or deliberate introduction of an unconditioned stimulus along with a conditioned stimulus; in operant conditioning, a reinforcer is a stimulus, such as a reward, that strengthens a desired response.

reinforcement

in psychological terms: (1) in operant conditioning, a stimulus that, when presented following a response, leads to an increase in the frequency of emission of the response in the future. Also known as a reinforcer and more colloquially as a reward; (2) the process of strengthening the frequency of a response through presenting a reinforcement. reinforce vt . negative reinforcement the strengthening of the frequency of a response by removing an aversive stimulus.
