  • Title: The eccentricity effect of inhibition of return is resistant to practice.
    Author: Bao Y, Sander T, Trahms L, Pöppel E, Lei Q, Zhou B.
    Journal: Neurosci Lett; 2011 Aug 01; 500(1):47-51. PubMed ID: 21683762.
    Abstract:
    Inhibition of return (IOR) refers to a delayed responding to targets appeared at previously cued location relative to an uncued novel location. In a recent study, Bao and Pöppel reported a functional dissociation of inhibitory processing in the visual field with much stronger IOR magnitude in the far periphery relative to the perifoveal visual field up to 15° eccentricity. The present study aimed to examine whether this effect is sensitive to participant experience or practice. Consistent with previous findings, our data demonstrated a larger IOR magnitude at 21° relative to 7° stimulus eccentricity. More importantly, no practice-related IOR magnitude changes were observed for both perifoveal and peripheral stimuli, although response times did decrease significantly with practice. These results suggest that the eccentricity effect of IOR is a robust phenomenon which is resistant to practice.
