• SEAH CHANG

    I am a postdoctoral researcher at the Ohio State University working jointly with Drs. Andrew Leber and Julie Golomb. I received my PhD from Johns Hopkins University in 2021, under the supervision of Dr. Howard Egeth.

     

    My research focuses on the influence of top-down mechanisms on the orienting of attention. Specifically, I use psychophysical, eye tracking, electrophysiological (ERPs), and neuroimaging (fMRI) techniques to study how inhibitory processes influence the efficiency of visual search, and how inhibitory and facilitatory processes are coordinated to guide visual attention.
