About

Using a noninvasive eye tracker, the investigators will measure how participants move their eyes to objects arrayed on a computer screen. Participants will be asked to find one element among many.

Full description

The investigators measure how quickly and how accurately participants can move their eyes from a central fixation point to a target object arrayed with one or more distractor objects. A noninvasive eye tracker will be used to measure their eye movements. Participants may also be asked to make a decision about a feature of the target they have selected with a key press. Difficulty of the search for the target object and difficulty of the decision about a feature of the target object will be manipulated.
