An interactive classroom demonstration of Posner's spatial cueing task, measuring how a brief visual cue speeds or slows detection of a target at a validly or invalidly cued location.
Contributed by Psychology Department
Students respond to left or right targets that are preceded by a cue at either the same (valid) or opposite (invalid) location, using the left and right arrow keys. After 4 practice trials and 24 experimental trials, the tool displays mean and median reaction time and accuracy for valid and invalid trials, and lets students download their trial-level data as a CSV.
