简要总结
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.
详细描述
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).

结局指标
主要结局
Button Press Reaction Time
时间窗: One day (during testing)
Speed to respond correctly to the target- after participant finds the target shape on a computer screen, they press a button to indicate what shape they see
Button Press Accuracy
时间窗: One day (during testing)
Accuracy of responses to target item (% correct)- the researchers will measure whether the participants presses the correct button which corresponds to the target shape presented on the computer screen or the incorrect button
Steady-State Visually Evoked Response (SSVEP)
时间窗: One day (during testing)
Brain response to visual stimuli flashing at a pre-defined frequency
