This paper describes data which for the first time show correlations between the visual steady state evoked response (SSER) and human cognitive activity. Individual subjects exhibit characteristic evoked potential phase relationships to flicker stimuli, and these were found to be related to the individual's speed of response in a memory scanning task. In addition, evoked response phase lags to different flicker frequencies were related to the component processes involved in the task. The brain's response to high frequency flicker is related to the sensory input portion of a memory scanning task while the response to medium frequency flicker is related to the memory look‐up aspects of this task.
