We have become used to talk about attention in terms of the forces that act on it. We may say that the sound or sight of a Twitter notification ‘pulled’ our attention away from our work. Or we might be ‘glued’ to a captivating story in a book. The Posner cueing task measures how attention is pulled across our visual field even when our eyes remain fixated.
The Flanker task was originally described by Eriksen & Eriksen (1974) as a test of the participants’ ability to inhibit conflicting but irrelevant information using a simple experimental paradigm.
The attentional blink can be tested using Rapid serial presentation of visual stimuli, where stimuli are shown sequentially at very short presentation times, usually around 15-75 milliseconds.
