An avoidance response is a response that prevents an aversive stimulus from occurring. It is a kind of negative reinforcement. An avoidance response is a behavior based on the concept that animals will avoid performing behaviors that result in an aversive outcome.
Superimposed schedules of reinforcement can create the three classic conflict situations (approach–approach conflict, approach–avoidance conflict, and avoidance–avoidance conflict) described by Kurt Lewin (1935) and can operationalize other Lewinian situations analyzed by his force field analysis. Other examples of the use of superimposed ...
For example, shielding one's eyes from sunlight terminates the (aversive) stimulation of bright light in one's eyes. (This is an example of negative reinforcement, defined above.) Behavior that is maintained by preventing a stimulus is called "avoidance," as, for example, putting on sun glasses before going outdoors.
Intermittent or partial reinforcement: Partial or intermittent negative reinforcement can create an effective climate of fear and doubt. Partial or intermittent positive reinforcement can encourage the victim to persist - for example in most forms of gambling, the gambler is likely to win now and again but still lose money overall.
Excessive avoidance has been suggested to contribute to anxiety disorders, leading psychologists and neuroscientists to study how avoidance behaviors are learned using rat or mouse models. [1] Avoidance learning is a type of operant conditioning (also known as instrumental conditioning).
The avoidance response is a form of negative reinforcement which is learned through operant conditioning. This response is usually beneficial, as it reduces risk of injury or death for animals, also because it is an adaptive response and can change as the species evolves.
The process of EA is thought to be maintained through negative reinforcement — that is, short-term relief of discomfort is achieved through avoidance, thereby increasing the likelihood that the avoidance behavior will persist. Importantly, the current conceptualization of EA suggests that it is not negative thoughts, emotions, and sensations ...
When the correct action is performed the animal receives positive reinforcement in the form of food or other reward. In some cases, the chamber may deliver positive punishment to discourage incorrect responses. For example, researchers have tested certain invertebrates' reaction to operant conditioning using a "heat box". [11]
