Eeg Study Of The Featural And Configural Components Of Face Perception, Heather Rose Stegman
Eeg Study Of The Featural And Configural Components Of Face Perception, Heather Rose Stegman
Summer Research
Prior research using functional magnetic resonance imaging (fMRI) suggests that facial features (i.e. eyes, nose, and mouth) and their configuration (i.e. T-shaped arrangement of features) are processed in different face-specific brain regions. However, precise response time of featural and configural face processing is unknown. Featural processing may occur before configural processing, or configural processing may occur before featural processing; conversely, they may occur simultaneously. Here, using the electroencephalography (EEG), we will examine the face-specific event related potential (ERP), the N170, to analyze temporal differences between featural and configural face processing.

Summer Research
The purpose of this study was to explore the role of the human mirror neuron system (hMNS) in the accurate identification of emotional facial expressions. Electroencephalography (EEG) was used to record Mu wave activity while participants preformed a series of video-matching tasks, in which they discriminated between facial stimuli by either emotional expression or model identity. A polygon-matching task was used as a baseline measure for mirror neuron activity. Mu Suppression Indices were calculated and compared between the identity-matching and emotion-matching conditions. Mu suppression was significantly increased in the emotion-matching condition, suggesting that the mirror neuron system is engaged to …
