본 연구는 단어 재인에서 작업 기억의 역할을 규명하기 위하여 진행되었다. 단어 재인에서의 작업 기억 역할 규명을 위하여 단어 빈도와 직업 기억 부담을 조절한 명명 과제 실험을 실시하였다. 실험 결과 단어 빈도는 작업 기억 부담에 영향을 받는 것으로 분석되었다. 작업 기억의 부담은 고빈도 단어 재인에서보다 저빈도 단어 재인에서 더 높은 영향을 미쳤다. 이러한 결과는 작업 기억이 저빈도 단어 재인에서 더 많은 영향을 갖음을 시사하는 것이다.

Abstract ▼ AI-Helper

This study was conducted in order to investigate the role of working memory in word recognition. As a preliminary step in tackling this topic, word frequency and working memory load were manipulated in a naming task. The results showed that word frequency is significantly involved with the working memory load. The effects of working memory load were greater in low-frequency word processing than in high-frequency word processing. These results indicat that working memory is involved more in the processing of low-frequency words. The implications for the teaching of children at the early reading acquisition stage are discussed in this paper.

제안 방법

A voice recorder measured the reaction time of the first phoneme pronounced by the subject. After 1000 ms of word naming, the memory test was conducted. After the memory test was scored, only the words that were correct in the trial were analyzed.
This preliminary study was conceived for the purposes of investigating the relationship between working memory and the word frequency effect, the primary indicator of word recognition. According to Sternberg's logic in [13], if manipuation of working memory capacity affects the processing of high-frequency words and low-frequency words by different degrees, then working memory somehow plays a role in the early processing of word recognition[13].
This study used the lexical decision task for words with different frequencies while conducting the working memory task. The method section described these related procedures and stimuli more specifically.

대상 데이터

Subjects Sixty students enrolled in the Introductory Psychology class at Pusan National University participated in the experiment. All of subjects had normal vision.
Procedures. The participants were sat down at a Pentium III PC, and the stimuli were presented, singly in sequence, on the center of the computer screen. All of stimuli were presented as white character on a dark background.

데이터처리

The reaction time responses for words were analyzed by ANOVA. Error analysis was not performed, because the rates were too low for every condition.
