AI Article Synopsis
- The study examined how people can ignore distractors while recognizing target letters, using a task where distractor digits flank these targets.
- Participants showed faster reaction times when distractors were repeated rather than changed, indicating that they could effectively inhibit the impact of the distractors.
- The findings suggest that the ability to ignore distractors is influenced by timing, with the most efficient inhibition occurring when the distractors and targets appear simultaneously.
Article Abstract
The present study investigated distractor inhibition on the level of stimulus representation. In a sequential distractor-to-distractor priming task participants had to respond to target letters flanked by distractor digits. Reaction time and stimulus-locked lateralized readiness potentials (S-LRPs) of probe responses were measured. Distractor-target onset asynchrony was varied. For RTs responses to probe targets were faster in the case of prime-distractor repetition compared to distractor changes indicating distractor inhibition. Benefits in RTs and the latency of S-LRP onsets for distractor repetition were also modulated by distractor-target onset asynchrony. For S-LRPs distractor inhibition was only present with a simultaneous onset of distractors and target. The results confirm previous results indicating inhibitory mechanisms of object-based selective attention on the level of distractor representations.
