Temporal predictability does not impact attentional blink performance: effects of fixed vs. random inter-trial intervals.

ABSTRACT:

Background

Does the inclusion of a randomized inter-trial interval (ITI) impact performance on an Attentional Blink (AB) task? The AB phenomenon is often used as a test of transient attention (Dux & Marois, 2009); however, it is unclear whether incorporating aspects of sustained attention, by implementing a randomized ITI, would impact task performance. The current research sought to investigate this, by contrasting a standard version of the AB task with a random ITI version to determine whether performance changed, reflecting a change in difficulty, engagement, or motivation.

Method

Thirty university students (21 female; age range 18-57, M _age= 21.5, SD = 7.4) completed both versions of the task, in counterbalanced order.
