Abstract
This experiment investigated interactions between spatial and temporal attention using an attentional blink (AB) procedure. The target letter, defined by color, was presented amongst distractor letters in a rapid serial visual presentation (RSVP) stream. The probe was a light dot that could occur in various positions in relation to the RSVP stream i.e. close or further away. The probe could occur at various stimulus onset asynchronies before and after the target. The effect of the probe's spatial and temporal distance from the target was compared in single- (respond only to the probe) and dual-task (respond to the target and probe) conditions. Results are considered in relation to the spotlight, gradient and selective tuning models of visual attention.
