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).
In free-operant avoidance a subject periodically receives an aversive stimulus (often an electric shock) unless an operant response is made; the response delays the onset of the shock. In this situation, unlike discriminated avoidance, no prior stimulus signals the shock. Two crucial time intervals determine the rate of avoidance learning.
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.
This unique aspect of the theory emphasizes the proactive nature of learning in avoidance behaviors. Sidman's work emphasized the principles governing the acquisition and maintenance of avoidance behavior. He explored how organisms, both human and non-human, learn to perform specific behaviors to prevent or avoid aversive consequences.
The 62-item Multidimensional Experiential Avoidance Questionnaire (MEAQ) [25] was developed to measure different aspects of EA. The Brief Experiential Avoidance Questionnaire (BEAQ) is a 15-item measure developed using MEAQ items, which has become the most widely used measure of experiential avoidance. [26]
According to Gray, personality traits are associated with individual differences in the strengths of BAS (approach motivation) and BIS (avoidance motivation) systems. As it is defined for the remainder of the article, higher BAS/BIS refers to greater activation of that system. [21]

Overmier's research activities have encompassed diverse areas such as learning, memory, stress, and the underlying biological substrates. [31] His work involved a wide array of animal models and human clients with specific dysfunctions to explore cognitive and biological aspects of stress, conditioning, learning, and memory in both animals and ...
