Abstract: Location-based inhibition of return (IOR) refers to a slowed response to a target appearing at a previously attended location. We investigated whether IOR time course and magnitude of deaf participants in detection tasks was changed after auditory deprivation. In Experiment 1, we observed comparable IOR time course and magnitude in both deaf and matched hearing participants. In contrast, results of Experiment 2 showed that less IOR in matched hearing participants was found when the fixation cue was absent with a 350ms-SOA, indicating that deaf participants disengaged attention faster than matched hearing participants. Deaf participants responded significant faster to the peripheral targets than the hearing participants, suggesting that deaf people possess enhanced peripheral attentive resources compared with matched hearing participants. Those results indicate that spatial attention is more effective and strategic for deaf participants than matched hearing participants.
