Abstract

本研究では,ワーキングメモリの負荷が精神活動の指標である瞬目活動に及ぼす影響について検討した.実験では,日本語版リーディングスパンテスト(RST)を用いてワーキングメモリの負荷を操作した.実験参加者は,大学生・大学院生15名であった.その結果,(1)負荷が低い2文および負荷が非常に高い5文では,再生中の瞬目率の方が再生後の瞬目率より有意に高かった.(2)再生中の瞬目率では各文条件間で有意差は認められなかったが,再生後の瞬目率では3文および4文は2文より有意に高かった.このことは,ワーキングメモリ上の処理資源の減少が瞬目活動に影響を与えることを示唆する.(3)外的注意を伴う音読中の瞬目率は,内的注意を伴う再生中および再生後の瞬目率より有意に低かった.(4)瞬目率ピークは,再生指示の開始後や再生開始直後に形成された.このことは,刺激の処理終了や認知的努力を伴う意識的処理が行われたことを示唆する.

We examined the effect of working memory load on eyeblink activity, which is an index of mental activity, by manipulating working memory load using the Japanese edition of the Reading Span Test (RST). Fifteen healthy graduate and undergraduate students participated in the study. Results indicated the following, (1) The eyeblink rate while recalling 2 low load sentences and 5 very high load sentences was significantly higher than the eyeblink rate after completing recall. (2) There was no significant difference in the eyeblink rate between high and low load sentences during recall. However, the eyeblink rate after recalling 3 or 4 sentences was significantly higher than that after recalling 2 sentences. These findings suggest that a decrease in processing resources of working memory influences eyeblink activity. (3) The eyeblink rate while reading aloud with attention focused externally was significantly lower than the eyeblink while recalling and after recalling with attention focused inwardly. (4) The eyeblink rate peak occurred after receiving recall instructions, or immediately after starting recall. This suggests that processing of stimuli was completed and conscious processing using cognitive effort was performed.
