Document Summary
Chapter 17- biopsychology of emotion, stress and health. In 1937, papez proposed that emotional expression is controlled by several interconnected nuclei and tracts that ring the thalamus- now known as the limbic system. In primates, most of the symptoms appear to result from damage to the amygdala. Innocent suspects, because they have no knowledge of the crime, react to all such details in the same way; the guilt act differentially. If the defending intruder stands firm against this lateral attack , the alpha male reacts by making a quick lunge around the defender"s body in attempt to bite its back. Neural mechanisms of fear conditioning: fear conditioning is the establishment of fear in response to a previously neutral stimulus (the conditional stimulus) by presenting it, usually several times, before the delivery of an aversive stimulus (the unconditional stimulus) In studies that use suppression paradigms, participants are directed to inhibit their emotional reactions to unpleasant films or pictures.
