The aim of this study was to determine whether the greater inhibition reduces the interference of the ignored stimulus (inhibition-build-up hypotheses ; Tipper & Cranston, 1985). Tipper & Cranston (1985) has proposed that when same stimulus is repeatedly ignored (repeated ignored condition), inhibition builds up and reduces the interference of the ignored stimulus. Adults were administered tasks of visual selective attention. They were requested to categorize target pictures, and not to response the ignored pictures. Relative to comparative condition (where an non-semantic picture as the ignored stimulus is presented throughout task), RTs in ignored condition (where the ignored stimulus varies in each trials and is never the same as the subsequent ignored stimulus) were slower for responses to a target. But. RTs in repeated ignored condition (where the ignored stimulus is the same throughout task) and RTs in comparative condition showed no significant difference. Also, relative to ignored condition, interference effect is smaller. This result is suggested that the greater inhibition reduces the interference. Interpretation of this result and further study are briefly discussed.
