Social learning of fear

Nature Neuroscience, 2007
Research across species highlights the critical role of the amygdala in fear conditioning. However, fear conditioning, involving direct aversive experience, is only one means by which fears can be acquired. Exploiting aversive experiences of other individuals through social fear learning is less risky.

Fears, phobias, and preparedness: Toward an evolved module of fear and fear learning.

Psychological Review, 2001
An evolved module for fear elicitation and fear learning with 4 characteristics is proposed. (a) The fear module is preferentially activated in aversive contexts by stimuli that are fear relevant in an evolutionary perspective. (b) Its activation to such stimuli is automatic. (c) It is relatively impenetrable to cognitive control.

Learning history in fear of blushing

Behaviour Research and Therapy, 1999
Two studies, investigating the learning history (i.e. traumatic conditioning experiences, vicarious learning, informational learning) of individuals with and without fear of blushing, are presented. In study 1, individuals high (n = 61) and low (n = 59) in fear of blushing completed the (revised) Phobic Origin Questionnaire [POQ; Ost, L. G., & Hugdahl,

Representing Fear in Learning in Organizations

Management Learning, 1997
Literature and practice on learning in organizations often seem to ignore the expression of fear. This article explores the role of representations of fear in collective learning. Three expressions offers are analysed: by Pat, an individual whose workplace trials parallel those of the authors; by Ricardo Semler, Brazilian business executive, whose ...

Chemical Transfer of Learned Fear

Nature, 1968
RESULTS reported earlier1–5 have suggested that acquired information can be transmitted to naive animals by giving them material extracted from the brain of trained subjects. In most of these experiments, as in others6–11, transfer of information was suggested by varying degrees of statistical probability and it was challenged by negative results ...

Facilitation of fear learning by prior and subsequent fear conditioning

Behavioural Brain Research, 2018
Classical fear conditioning is perhaps the premier model system used to study the neurobiological basis of memory formation. Prior work has resulted in a good understanding of both the molecular mechanisms and neural circuits supporting this form of learning.

Exercise and Fear and Safety Learning

Fear conditioning paradigms have been studied for over 100 years and are of great interest to the behavioral and clinical sciences given that several safety learning processes (e.g., extinction learning and recall) are thought to be fundamental to the success of exposure-based therapies for anxiety and related disorders.

Generalization of Learned Fear

2016
Autonomic hyperarousal and avoidance in post-traumatic stress disorder (PTSD) can be triggered by a host of stimuli or situations that bear some similarity or association to the trauma event. As these triggers are often encountered in safe environments removed from the original trauma, this overgeneralization of fear and anxiety is a burden that can ...

Fear learning and extinction

2019
Abstract Experimental fear conditioning and extinction represent basic forms of associative learning with considerable clinical relevance and serve as laboratory models for the development and treatment of anxiety disorders, respectively.
