Psychophysiological Markers of Fear and Anxiety
- 97 Downloads
Purpose of Review
The purpose of this paper is to provide a current review of the recent literature (2015–2018) on psychophysiological markers of fear and anxiety.
Relative to healthy controls, fear-based disorders are characterised by heightened physiological reactivity to circumscribe threat salient stimuli, whereas anxiety-related disorders are associated with a more blunted pattern of physiological reactivity.
Fear and anxiety disorders are marked by abnormal patterns of physiological reactivity, characterised by hyper- and hypo-reactivity in response to stimuli varying in threat salience.
