What is Reinforcement?
is a tern in operant conditioning and behavior analysis for the delivery of a stimulus,(immediately or shortly) after a response, that results in an increase in the future rate or probability of that response
-
Positive reinforcement
is and increase in the future frequency of a behavior due to the addition of a stimulus immediately following a response. Example: giving food to a dog contingent on its sitting is an example of positive reinforcement.
-
negative reinforcement
an increase in the future frequency of a behavior when the consequence is th removal of an aversive stimulus. Example: Turning off (or removing) an annoying song when a child asks their parent .
-
avoidance conditioning
occurs when a behavior prevents an aversive stimulus from starting or being applied
-
Escape Conditioning
occurs when behavior removes an aversive stimulus that has already started.
-
Primary Reinforcers
sometimes called unconditioned reinforcer- a stimulus that does not require pairing to function as a reinforcer and most likely has obtained this function through the evolution and its role in species survival
Ex. sleep, food, air, water and sex.
-
Secondary Reinforcers
Conditioned reinforcer- a stimulus or situation that has acquired its function as a reinforcer after pairing with a stimulus which functions as a reinforcer.
Ex. sound of a clicker, as used in clicker training. The sound of the clicker has been associated with praise or treats and subsequently, the sound of the clicker may function as a reinforcer.
-
generalized reinforcer
a conditioned reinforcer that has obtained the reinforcing funtion by pairing with many other reinforcers
ex. money, a secondary generalized reinforcer
-
Reinforcer sampling
potentially reinforcing but unfamiliar stimulus is presented to an organism without regard to an prior behavior
-
Socially mediated reinforcement
Direct reinforcement- involves the delivery of reinforcement which requires the behavior of another organism
-
Premack principle
special case of reinforcement elaborated by David Premack, which states that a highly preferred activity can be used effectively as a reinforcer for a less preferred activity.
-
Reinforcement hiearchy
list of actions, rank-ordering the most desirable to least desirable consequences that may serve as a reinforcer. a reinforcement hierarchy can be used to determine the relative frequency and desirability of differant activities, and is often employed when applying the Premack principle
-
Contingent
outcomes are more likely to reinforce behavior than non-contingent responses. those directly linked to a causal behavior, such a light turning on being contingent on flipping a switch.
-
Contguous
stimuli closely associated by time and space with specific behaviors. They reduce the amount of time needed to learn a behavior while increasing its resistance to extinction.
Ex. giving a dog a piece of food immediately after sitting is more contiguous with (and therefore more likely to reinforce) the behavior than a several minute delay in food delivery following the behavior.
-
Noncontingent reinforcement
response-independent delivery of stimuli identified serve as reinforcers for some behaviors of that organism. typically entails time-based delivery of stimuli identified as maintaining aberrant behavior, which serves to decrease the rate of the target behavior.
