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]
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 ...
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.
Exposure therapy is based on the principle of respondent conditioning often termed Pavlovian extinction. [10] The exposure therapist identifies the cognitions, emotions and physiological arousal that accompany a fear-inducing stimulus and then tries to break the pattern of escape that maintains the fear.
Some physiological changes also occurred including the decrease in body weight gain and adrenal hypertrophy observed in animals exposed to stress. Overall, the conditioned fear responses can contribute to behavioral changes in a repeated stress paradigm. This can be extended to correlate to other animals as well but with varying degrees of ...
A useful and scientific collection of research-backed tips for overcoming your chronic fears and daily stressors.
Systematic desensitization (a guided reduction in fear, anxiety, or aversion [10]) can then be achieved by gradually approaching the feared stimulus while maintaining relaxation. Desensitization works best when individuals are directly exposed to the stimuli and situations they fear, so anxiety-evoking stimuli are paired with inhibitory responses.
A study done by Loftis and Ross in 1974 looked at the effects of misattribution of arousal upon acquisition and extinction of a conditional emotional response. They conducted two experiments with 89 female undergraduates to show that misattribution procedures can alter physiological response to a conditioned source of a fear or arousal.
