Abstract
If two objects are serially presented, and subjects are required to match them at basic-level, latencies for "no-match" responses are greater when the stimuli belong to common superordinate category (Superordinate Similarity Effect, SSE). For picture-word matching task, this effect was observed only at word-precede-picture condition, and not at picture-precede-word condition. In this experiment a picture (line drawing) and a word (kana) was presented, one to left and the other to right visual field simulatneously. 2 way within-subject analysis of variance showed significant main effect of both common superordinate and presentation position but no significant interaction between them. These results revealed that (1) SSE is observed at simultaneous picture-matching task, and (2) Average latency is greater when word is presented to left visual field (right hemisphere) and picture is presented to right visual field (left hemisphere). (3) There is no interaction between SSE effect and hemispheric laterality.
