About

In this line of research, the researchers are utilizing an EEG measure of repeated visual stimulation, the Steady-State Visually Evoked Potential (SSVEP) to examine processing of target and distractor information during visual search. This is a basic science study.

Full description

The researchers are interested in how the brain responds to target and distractor information during visual search. The researchers will manipulate the information available to the research participants, and measure research participants brain responses to information matching target or distractor features utilizing an EEG measure of repeated visual stimulation, the Steady-State Visually Evoked Potential (SSVEP).
