Abstract
The purpose of present study is to investigate the underlying mechanism of wordnferiority effect (WIE) when detecting position-transposed-characters (PTCs).revious studies suggested English WIE was involved with visual recognition process,hile Chinese WIE was involved with semantic integration process. This study usedwo experiments to further investigate this issue. Experiment 1 manipulated contextredictability of targets (high, low), and target types (Chinese radicals, PTCs). Ifhinese WIE was involved with semantic integration process, the detection ratehould be higher when target predictability was low. On the contrary, detection rate ofhinese radical should not be affected by target predictability. Experiment resultsere consistent with the prediction. The results therefore suggested Chinese WIE wasnvolved with semantic integration. Experiment 2 investigated the relationshipetween detection mechanism of PTCs and visual fields. Researcher performedoving Window Paradigm with an eye tracker. In the experiment, participants would read sentences in 3 different display conditions (full, fovea only, parafovea only). While reading, participants needed to detect 3 different types of targets (Chinese radical, PTCs, substitution of phonological-similar character). Results showed the pre-process of PTCs in parafovea increased the detection rates. The results suggested that both fovea and parafovea provided information to semantic integration process. Present study supports that Chinese WIE is involved with semantic integration process. The nature of semantic integration process and how this process is relating to PTC detection are also discussed.
