영문 초록

The experiments explored the time course of both the negative repetition effect (the NRE) which refers to a poorer detection of repeated inputs than nonrepeated inputs in the displays and its opposite, the positive repetition effect (the PRE). Experiment 1 demonstrated that displays in which a weak target was presented with a strong noise produced a larger NRE than displays in which a strong target was presented with a weak noise, suggesting that processing identical feature inputs is inhibited in a postcuing, forced-choice task (Bjork & Murray. 1977). In Experiment 2, the stimulus-onset-asynchrony (SOA) between the target and the noise letter was varied. The dimension letters(e.d., "ㅗ vs. ㅜ”) just differing in configutations produced the largest PRE at a 0-msec SOA whereas the feature letters (e.g., “ㅗ vs. ㅠ”) differing in terms of the presence or absence of a feature yielded the largest NRE when the noise preceded by 50 msec the target. Also found were two different types of the NRE: the NRE of the physical codes and that of the name codes. The feature-specific inhibition (Bjork Murray, 1977), response bias (e.g., Eriksen, Morris, Yeh, O`hara & Durst, 1981), criterion adjustments (Estes, 1982), and pathways (Kim & Kwak, 1987) models were examined in two experiments. The major results of the present study were best accounted for the Kim and Kwak model that assumes parallel pathways that handle qualitatively different information.
