Modeling The Neural Circuitry Underlying The Behavioral And Eeg Correlates Of Attentional Capture, Chloe Callahan-Flintoft, Brad Wyble
MODVIS Workshop
The Reactive-Convergent Gradient Field model (R-CGF) is a unique approach to modeling spatial attention in that it links neural mechanisms to event related potentials (ERPs) from scalp EEG. This model was developed with the aim of explaining different, sometimes conflicting, findings in the attention literature. Specifically, this model address conflicting findings showing both simultaneous and serial deployment of attention. Another argument addressed by the model is whether attention to a location invokes a suppression of the spatial surround, or the selective inhibition of distractors. With the R-CGF, we have found that these results are not as incompatible as they appear …

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.
