- Abstract
The aim of the present study was to investigate the possibility that a shift toward a within-hemisphere advantage would emerge when two stimulus items receive, respectively, different processing (vs. when they receive similar processing). Using right-handed participants, we briefly presented two Kanji color-word items as either within-field or across-fields. Viewers had to match the two items in terms of ink color (a color-matching task) or word meaning (a name-matching task). Each Kanji color word was presented with the same (congruent) or different (incongruent) ink color relative to the word meaning. Our results were twofold. First, a within-field advantage appeared in the relatively easier color-matching task, whereas an across-field advantage tended to occur in the relatively harder name-matching task. Second, in the word-matching task an across-field advantage appeared when both Kanji color words appeared in similar processing manners (both congruent or both incongruent), whereas a within-field advantage occurred when processing of two Kanji items differed (one congruent and one incongruent). These results suggested that a shift toward a within-hemisphere advantage occurs when two items are processed in respectively different ways.
