Spatial Cueing (Posner) Task
Description
A classic spatial cueing paradigm (Posner's cueing task) measuring attentional orienting via valid, invalid, and neutral cues.
Measures: Attentional orienting, cueing benefit/cost, simple reaction time
Attention
About This Test
A fixation cross appears with a directional arrow cue (left, right, or both). After a variable delay, a target X appears to the left or right. Participants respond as quickly as possible when the target appears. The arrow cue is valid (correctly predicts target location) on most trials, creating a cueing benefit for valid trials and a cost for invalid trials.
