Examining conscious and non-conscious processing processing of fearful facial expressions: Effects of Autonomic Arousal

Proposal details

Title: Examining conscious and non-conscious processing processing of fearful facial expressions: Effects of Autonomic Arousal
Research Area(s): Brain Imaging
Background: This research expands on Lea Williams' NeuroImage paper published in 2001. Williams reported an amygdala-hippocampal dissociation in 11 healthy volunteers. It was reported that amygdala-medial frontal activity was observed only with SCRs, whilst hippocampus-lateral frontal activity occurred only in the absence of SCRs.
Aims: The current study will use fMRI with simultaneous SCRs to investigate the effects of SCR on conscious and non-conscious processing of fearful facial expressions in a much larger sample of healthy volunteers.
Method: An SPM Analysis of Variance (ANOVA)analysis will examine differences between the conscious and non-conscious processing of fearful facial expressions and between activations associated with SCR activity and activations associated with the absence of SCR activity.
