Koraly Pérez-Edgar is interested in the relations between temperament and psychopathology. Children with the extreme temperamental trait of behavioral inhibition show increased risk for social anxiety. However, individual differences in attention mechanisms may play an important role in shaping this risk. In conducting her work, Dr. Pérez-Edgar uses multiple methods including behavior observation, psychophysiology (EEG & ERP), and neuroimaging (fMRI). One important study will examine how the relation between attention and emotion emerges in the first two years of life. The study will recruit families and infants from the main Penn State campus and from PACT facilities at Harrisburg.
