THE EFFECT OF OBJECT-BASED SELECTION ON THE SEPARATED STROOP TASK
The Stroop Effect (SE) documents the failure to ignore the carrier color word when people report its ink color (Stroop, 1935). Despite the vast amount of Stroop research, a few studies only investigated the effect of input selectionâ€”object-based or space-basedâ€”on the SE. The results were inconclusive. Moreover, the studies showing object-based modulation of the SE used the classic, integrated Stroop task, whereas studies showing space-based modulation typically used the spatially-separated version of the Stroop task. In this study we employed spatially separated Stroop displays to study the effect of object-based selection on the SE. The results showed larger SEs when the word and the color patch were part of the same object. This suggests improved processing of all features of an attended object, even if irrelevant to the task.
