I am conducting a priming experiment that involves the presentation of stimuli at 17milliseconds and 34 milliseconds. the stimuli comprises of African American and Caucasian faces. At such presentation speed (17 - 34ms), I should not be able to see the face at all, much less be able to make out whether the particular face presented is Black or White. The problem is that I am seeing the faces, and that is holding up the experiment.
Any suggestions??? Thanks in advance.
