In fear conditioning, the main circuits that are involved are the sensory areas that process the conditioned and unconditioned stimuli, certain regions of the amygdala that undergo plasticity (or long-term potentiation) during learning, and the regions that bear an effect on the expression of specific conditioned responses.
Fear is an unpleasant emotion that arises in response to perceived dangers or threats. Fear causes physiological and psychological changes. It may produce behavioral reactions such as mounting an aggressive response or fleeing the threat, commonly known as the fight-or-flight response. Extreme cases of fear can trigger an immobilized freeze ...
Pavlovian fear conditioning is a behavioral paradigm in which organisms learn to predict aversive events. [1] It is a form of learning in which an aversive stimulus (e.g. an electrical shock) is associated with a particular neutral context (e.g., a room) or neutral stimulus (e.g., a tone), resulting in the expression of fear responses to the originally neutral stimulus or context.
Fear extinction is the fundamental principle behind exposure therapy, a common treatment for anxiety disorders. In this process, the conditioned fear responses diminish progressively over time, when the previously conditioned stimulus is presented without being paired with the unconditioned stimulus. [20]
It may also be called "conditioned suppression" or "conditioned fear response (CFR)." [1] It is an "emotional response" that results from classical conditioning, usually from the association of a relatively neutral stimulus with a painful or fear-inducing unconditional stimulus. As a result, the formerly neutral stimulus elicits fear.
Fear-potentiated startle (FPS) is a reflexive physiological reaction to a presented stimulus, and is an indicator of the fear reaction in an organism. The FPS response can be elicited in the face of any threatening stimulus (e.g., any object, person or situation that would cause someone to experience feelings of fear), but it can also be elicited by a neutral stimulus as a result of fear ...
Protection motivation theory was developed by R.W. Rogers in 1975 in order to better understand fear appeals and how people cope with them. [1] However, Dr. Rogers would later expand on the theory in 1983 to a more general theory of persuasive communication.
According to fear appeal studies, a fear appeal has two components: a component of threat and a component of efficacy. These two components are further divided into two categories each. The threat component is composed of severity and susceptibility, while the efficacy component is composed of response efficacy and self-efficacy.
