초록

본고에서는 Baddeely(2000)의 작업기억 모형에서 외현적 조음억제가 조음체제의 음성하 시연을 상당부분 차단할 수 있다는 가정에 대해 제기되는 두 가지 문제, 즉 1)언어중재이론에서 제안되는 외현적 조음억제와 음성하 조음억제의 차이의 문제와, 2)조음억제 과정에서 조음체제의 음성하 시연과 중앙처리장치의 주의체제에 의한 시연 즉 주의재생(attentional refreshing)과의 상호작용의 문제(Camos, Lager, & Barrouillet, 2009)를 밝히고자 하였다. 이를 위해 본고에서는 조음억제의 유형을 고려하고 조음체제와 주의체제의 상호작용을 고려하여, 단순기억, 외현적 조음억제, 음성하 조음억제, 주의억제, 주의억제+음성하 조음억제의 다섯 개의 기억조건을 구성하였고, 이 조건들이 즉시순차기억과제의 수행에 미치는 영향을 비교하였다. 연구결과를 보면, 첫째, 즉시순차기억에서 외현적 조음억제는 음성하 조음억제에 비해 부정적인 영향을 미치며, 둘째, 주의억제+음성하 조음억제는 주의억제 또는 음성하 조음억제에 비해 부정적인 영향을 미치는 것으로 나타났다. 본고의 결과 및 논의로부터 즉시순차기억에서 외현적 조음억제는 음성하 시연에 대한 조음억제의 부정적 효과를 과도하게 일반화 하며, 음성하 시연에 대한 외현적 조음억제의 부정적인 효과는 음성하 시연과 주의재생의 상호작용에 의해 감소된다는 결론을 도출하였다.

Abstract

The present study tried to clarify two issues derived from the assumption that overt suppression substantially suppress subvocal rehearsal in articulatory system in Baddeley's model, which are whether overt suppression has the same negative effect on subvocal rehearsal in articulatory system as subvocal suppression has, and whether there exists the interplay between two mechanisms of maintenance of verbal information, that is, subvocal rehearsal and attentional refreshing postulated in Camos, Lager, and Barrouillet's study(2009), in immediate serial recall tasks. We manipulated five suppression conditions including no suppression, overt suppression, subvocal suppression, attentional refreshing suppression, attentional refreshing suppression plus subvocal suppression, and evaluated five conditions' effects on immediate serial recall tasks. The results are as follows. First, overt articulatory suppression had more negative effect on immediate serial recall tasks than subvocal articulatory suppression had. Second, attentional refreshing suppression plus subvocal suppression had more negative effect on immediate serial recall tasks than each of subvocal articulatory suppression and attentional refreshing suppression had. Conclusions are that overt suppression overgeneralizes articulatory suppression's negative effects on subvocal rehearsal and overt suppression's effect on subvocal rehearsal in immediate serial recall tasks is diminished by the interplay between subvocal rehearsal and attentional refreshing.
