Prefrontal Cortex Activity During Attentional Bias Conditioning With Fearful Faces: A Near-Infrared Spectroscopy Analysis, Robert D. Torrence
All NMU Master's Theses
Observing a fearful facial expression elicits an automatic orienting of attention. Past research focusing on fear conditioning has used an unconditioned stimulus that the participant directly experiences (e.g. shock). Other research has focused on observational fear learning where the participant watches another individual receive the stimulus. The aim of this study was to condition a colored square with a fearful face in the dot-probe task. Orienting toward and disengagement from fearful faces was also examined using the dot-probe task. In addition, hemodynamic responses in the prefrontal cortex (PFC) were measured using near-infrared spectroscopy (NIRS). It was hypothesized that after pairing …
