The neuropsychology of fear learning and fear regulation.
In the current review article it is suggested that fear is a central emotional state that can be activated by external threat cues. The subcortical defensive system cannot only be activated by intrinsically aversive events but shows also strong plasticity enabling previously innocuous stimuli to get access to the fear system after they were paired with painful outcomes. On the other hand, avers...
متن کاملWorrying Affects Associative Fear Learning: A Startle Fear Conditioning Study
A valuable experimental model for the pathogenesis of anxiety disorders is that they originate from a learned association between an intrinsically non-aversive event (Conditioned Stimulus, CS) and an anticipated disaster (Unconditioned Stimulus, UCS). Most anxiety disorders, however, do not evolve from a traumatic experience. Insights from neuroscience show that memory can be modified post-lear...
متن کاملLearning strategies during fear conditioning.
This paper describes a model of fear learning, in which subjects have an option of behavioral responses to impending social defeat. The model generates two types of learning: social avoidance and classical conditioning, dependent upon (1) escape from or (2) social subordination to an aggressor. We hypothesized that social stress provides the impetus as well as the necessary information to stimu...
متن کاملImmunization against social fear learning.
Social fear learning offers an efficient way to transmit information about potential threats; little is known, however, about the learning processes that counteract the social transmission of fear. In three separate experiments, we found that safety information transmitted from another individual (i.e., demonstrator) during preexposure prevented subsequent observational fear learning (Experimen...
متن کاملLearning not to fear, faster.
Overcoming our fears is on everyone’s “to do” list. However, this is more difficult for some than others, especially those suffering from posttraumatic stress disorder (PTSD). To understand how the brain learns to feel safe, researchers have turned to extinction of classically conditioned fear. In extinction, mice learn that a tone previously paired with a footshock no longer predicts the shock...
