Abstract
Yamamoto, Kawahara & Ohtsuka(2008) explored basic-level picture-word serial matching task, and found that superordinate similarity effect (SSE) occurs only when prime words precede target pictures. In this experiment, we systematically manipulated SOA intervals (within participants design) and found that (1) only SOA effect was significant when prime pictures preceded target words; (2) only SSE effect was significant when prime words preceded target pictures; (3) no interaction between SSE and SOA effects was observed in both conditions.
