| summary | Much of past research in affective neuroscience has focused on how transient emotion processing influences perception or how top-down cognitive control modulates emotion processing. However investigation of such effects is often stimulus-locked, which does not necessarily provide an accurate model for understanding the effects of emotional states on perception and attention on a longer timescale. Using fMRI, we will show that induction of positive or negative mood for several minutes - via exposure to semantic information or movie clips - sensitize or desensitize subsequent amygdala responding to social and emotional information. We will also question the claim that repeated exposure to violent media desensitizes individuals to violence and participates to the long-term development of anti-social behaviours (Anderson et al 2010), and discuss how cognitive neuroscience may help testing such assumptions. |
