Escape response in Antarctic krill.. Escape response, escape reaction, or escape behavior is a mechanism by which animals avoid potential predation.It consists of a rapid sequence of movements, or lack of movement, that position the animal in such a way that allows it to hide, freeze, or flee from the supposed predator.
An escape response occurs when an aversive stimulus is presented and the subject makes a response to remove or escape the stimulus. In the laboratory, this is usually represented by a rat given a small shock to its feet through a grid floor and shuttling through a small opening in its chamber which stops the shock.
A defence mechanism can become pathological when its persistent use leads to maladaptive behaviour such that the physical or mental health of the individual is adversely affected. Among the purposes of ego defence mechanisms is to protect the mind/self/ego from anxiety or to provide a refuge from a situation with which one cannot currently cope ...
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.
For example, anger shows the sign of attack, fear shows the sign of escape. These emotional reactions interconnect with our mind and body. These negative emotions are influenced by the physiological support mechanisms, such as the physical energy, that relies on the body to mobilize at an optimal level for individual action to react.
Avoidance coping is measured via a self-reported questionnaire. Initially, the Multidimensional Experiential Avoidance Questionnaire (MEAQ) was used, which is a 62-item questionnaire that assesses experiential avoidance, and thus avoidance coping, by measuring how many avoidant behaviors a person exhibits and how strongly they agree with each statement on a scale of 1–6. [1]
The startle reflex is a brainstem reflectory reaction (reflex) that serves to protect vulnerable parts, such as the back of the neck (whole-body startle) and the eyes (eyeblink) and facilitates escape from sudden stimuli. It is found across many different species, throughout all stages of life.
Learned helplessness is the behavior exhibited by a subject after enduring repeated aversive stimuli beyond their control. It was initially thought to be caused by the subject's acceptance of their powerlessness, by way of their discontinuing attempts to escape or avoid the aversive stimulus, even when such alternatives are unambiguously presented.
