Abstract

According to the localization hypothesis(Tsal, 1989), attention merely facilitates feature localization porcesses, not the feature integration. In two visual conjunctive-target search tasks, subjects were previewed with the display containing half of features(color or form) of each item before presenting the full conjunction display. The hypothesis predicts that search slope in the preview condition would be reduced in half. However, the results failed to confirm the prediction, suggesting that feature localization alone may not be sufficient for conjunctive search.
