The dominant account of extinction involves associative models. However, there is debate over whether extinction involves simply "unlearning" the unconditional stimulus (US) – Conditional stimulus (CS) association (e.g., the Rescorla–Wagner account) or, alternatively, a "new learning" of an inhibitory association that masks the original excitatory association (e.g., Konorski, Pearce and ...
A simple example of this is conditioned food aversion, or the aversion developed to food that has previously resulted in sickness. Food aversions can also be conditioned using classical conditioning , so that an animal learns to avoid a stimulus previously neutral that has been associated with a negative outcome. [ 3 ]
Operant conditioning involves the modification of a behavior by means of reinforcement or punishment. In this way, a discriminative stimulus will act as an indicator to when a behavior will persist and when it will not. Classical conditioning involves learning through association when two stimuli are paired together repeatedly.
Classical conditioning occurs when a conditioned stimulus (CS) is paired with an unconditioned stimulus (US). Usually, the conditioned stimulus is a neutral stimulus (e.g., the sound of a tuning fork), the unconditioned stimulus is biologically potent (e.g., the taste of food) and the unconditioned response (UR) to the unconditioned stimulus is an unlearned reflex response (e.g., salivation).
Consequences that lead to appetitive behavior such as subjective "wanting" and "liking" (desire and pleasure) function as rewards or positive reinforcement. [2] There is also negative reinforcement, which involves taking away an undesirable stimulus. An example of negative reinforcement would be taking an aspirin to relieve a headache.
For example, a painful stimulus which would act as a punisher for most people may actually reinforce some behaviors of masochistic individuals. There are two types of punishment: positive and negative. Positive punishment involves the introduction of a stimulus to decrease behavior while negative punishment involves the removal of a stimulus to ...
For children, some of these variables could set the pattern for lifelong problems. For example, a child whose depressive behavior functions for negative reinforcement by stopping fighting between parents could develop a lifelong pattern of depressive behavior in the case of conflicts. Two paths that are particularly important are (1) lack or ...
Diagram of consequences in operant conditioning. The consequence of a behavior can be reinforcing or punishing. Reinforcing consequences increase the likelihood of a behavior occurring in the future; it is further divided into positive and negative reinforcement.
