Direct linkNorrholm, Seth D.; Jovanovic, Tanja; Vervliet, Bram; Myers, Karyn M.; Davis, Michael; Rothbaum, Barbara O.; Duncan, Erica J. – Learning & Memory, 2006
The purpose of this study was to analyze fear extinction and reinstatement in humans using fear-potentiated startle. Participants were fear conditioned using a simple discrimination procedure with colored lights as the conditioned stimuli (CSs) and an airblast to the throat as the unconditioned stimulus (US). Participants were extinguished 24 h…

Peer reviewedWolff, P. – Human Development, 1974
Reviews research which demonstrates that responses from different behavior systems to a given stimulus situation may be far from perfectly correlated with each other. Discusses the phylogenetic and ontogenetic development of these systems and the roles of both the species and the individual in bringing the systems into mutual correspondence.…

Myers, Karyn M.; Davis, Michael – Learning & Memory, 2004
The neural mechanisms of fear suppression most commonly are studied through the use of extinction, a behavioral procedure in which a feared stimulus (i.e., one previously paired with shock) is nonreinforced repeatedly, leading to a reduction or elimination of the fear response. Although extinction is perhaps the most convenient index of fear…
