Rightward shift in temporal order judgements in the wake of the attentional blink

The temporal order of two events, each presented in a different visual hemifield, is judged correctly by typical observers even when their onsets differ only slightly. The present study examined the influence of an endogenous process on TOJ, and shows that the perception of temporal order is also affected when available attentional resources are reduced via an attentional blink (AB) paradigm. Participants were presented with a first visual target stimulus (T1) at fixation and after a delay (either 280 or 1030 ms) a pair of lateralized stimulus occurred (T2). For the dual task and with the 280 delay between T1 and T2, accuracy in the TOJ deteriorated evincing an AB. However, instead of the left favoring asymmetry in normal attention conditions, a significant bias away from the left space emerged during the AB.
