자극-반응 부합성과 전역/국소 처리의 상호작용 효과에 관한 연구 = A Study on the Interaction between Global/Local Processing and Stimulus-Response Compatibility

다국어 초록 (Multilingual Abstract)

To examine the interaction between global/local-processing and stimulus-response compatibilities, the present study systematically manipulated the compound letters in terms of stimulus-stimulus congruity, the response levels(global vs. local), and the conceptual(Experiment 1) or spatial(Experiment 2) stimuli-response compatibilities. The results of the study can be summarized as followings: (1) In general, the performances of the subjects were better when they were provided compatible(both of conceptual and spatial), global, and congruent stimuli than incompatible, local, and incongruent stimuli. (2) When the stimuli were incongruent, the subjects' performances were impaired more in the local level condition than in the global level condition. (3) Although the subjects' performance was generally better in the S-R compatible condition than in the S-R incompatible condition, subjects' reaction time was increased more in the S-R compatible condition than in the S-R incompatible condition when incongruent stimuli were provided. And (4) reaction time in the global level condition increased greatly in the spatial S-R incompatible condition, whereas reaction time in the local level condition were similar for both spatial S-R compatibility conditions. Finally, issues related to this study were discussed.

국문 초록 (Abstract)

본 연구에서는 전역/국소 처리의 상대적 차이를 자극-반응 부합성과 관련하여 살펴보기 위하여 자극 속성(복합문자의 전역 혹은 국소 속성이 일치하거나 불일치)과 판단 수준(전역-속성에 대한 반응 혹은 국소 속성에 대한 반응), 그리고 개념적 자극-반응의 부합성(실험 1) 및 공간적 자극-반응 부합성(실험 2) 수준이 체계적으로 조작되었다. 본 연구의 결과를 요약하면 다음과 같다. 먼저, (1) 전반적으로 복합문자의 전역 속성과 국소 속성이 일치하는 경우, 전역-속성에 반응하는 경우, 그리고 개념적/공간적으로 부합하는 경우에서의 수행이 더 우수하였다. (2) 특히, 기존의 연구 결과와 마찬가지로 국소 속성에 대한 반응은 자극-자극이 불일치할 경우에는 전역 속성에 비해 더 많은 간섭을 받는다는 것이 관찰되었다. (3) 일반적으로 개념적 자극-반응 부합 조건에서의 수행이 우월하지만 자극-자극 불일치 조건의 경우에는 비부합 대응보다 부합 대응 조건에서의 반응시간이 상대적으로 더 많이 증가하였다. 그리고 (4) 국소 속성에 대한 반응은 반응해야 할 자극의 의미적 속성과 위치가 부합하거나 부합하지 않는 것에 관계없이 비교적 일정하고 느린데 반해, 전역 속성에 대한 반응은 자극이 제시된 위치가 자극의 의미와 비부합할 경우 간섭의 정도가 더 증가하였다. 이러한 결과들은 전역 처리가 국소 처리에 비해 처리에서의 우월성을 갖지만 개념적/공간적 자극-반응 부합성의 여부에 따라 전역 처리에 대한 간섭의 정도가 달라질 수 있음을 시사한다.
