Interventions

BEHAVIORAL

Target and Stimulus

The investigators manipulate the difficulty of search for the target object by manipulating the number of distractor objects and/or the similarity between the target and distractors. The investigators manipulate the difficulty of the decision about a feature by manipulating the similarity of the feature to a criterion. The investigators manipulate the timing of when the decision feature appears on the object relative to the onset of the array and/or the onset of the saccade away from fixation in a gaze-contingent manner.
