Fear Conditioning and Social Groups: Statistics, Not Genetics
Humans display more conditioned fear when the conditioned stimulus in a fear conditioning paradigm is a picture of an individual from another race than when it is a picture of an individual from their own race (Olsson, Ebert, Banaji, & Phelps, 2005). These results have been interpreted in terms of a genetic "preparedness" to learn to fear individuals from different social groups (Ohman, 2005; O...
متن کاملA twin study of the genetics of fear conditioning.
BACKGROUND Fear conditioning is a traditional model for the acquisition of fears and phobias. Studies of the genetic architecture of fear conditioning may inform gene-finding strategies for anxiety disorders. The objective of this study was to determine the genetic and environmental sources of individual differences in fear conditioning by means of a twin sample. METHODS Classic fear conditio...
متن کاملSocial Fear Conditioning Paradigm in Virtual Reality: Social vs. Electrical Aversive Conditioning
In a previous study we could show that social fear can be induced and extinguished using virtual reality (VR). In the present study, we aimed to investigate the belongingness effect in an operant social fear conditioning (SFC) paradigm which consisted of an acquisition and an extinction phase. Forty-three participants used a joystick to approach different virtual male agents that served as cond...
متن کاملMindfulness and Fear Conditioning
During mindfulness-based interventions participants can be invited to bring aversive stimuli to mind while practicing mindfulness. This is thought to help the stimuli become less aversive. However, the mechanisms underlying this process are not fully understood. In this study we explored these by examining the effects of mindfulness practice and stimulus visualization on stimuli associated with...
متن کاملVoluntary wheel running enhances contextual but not trace fear conditioning.
Exercise improves performance on a number of hippocampus involved cognitive tasks including contextual fear conditioning, but whether exercise enhances contextual fear when the retention interval is longer than 1 day is not known. Also unknown is whether exercise improves trace conditioning, a task that requires the hippocampus to bridge the time interval between stimuli. Hence, 4-month-old mal...
