Topic: attentional blink

Our attention falters, which is commonly known as ‘attentional blink’ (AB), after spotting a target; as a result, the subsequent target often goes unnoticed. Attentional demand also affects the size of the pupillary aperture. In previous studies, differential pupillary dilation averaged across trials within a short critical epoch distinguished AB. In contrast, we examined the pupil dynamics on a trial-by-trial basis. Healthy young volunteers performed a task, wherein two visual targets embedded in a series of distractors were presented in a rapid succession. The participants were asked to iden
