Abstract

木材使用量の異なる室内空間による視覚刺激が二桁加算・減算の作業効率に与える影響を検討した。供試空間はスギ材使用量の異なる4部屋を用いた。被験者は健常な大学生と一般成人の男女12名とし,室内で5分間安静にした後,計算作業を16分間行った。併せて心理評価と生理反応の変化を調べた。室内のイメージを調べた結果,部屋間で「快適性」「雰囲気」のイメージは有意に異なっていた。また,作業開始前の快不快感は有意に異なっていたが,作業終了後は全ての部屋で不快と評価され,部屋間で有意差は認められなかった。唾液アミラーゼ活性は,時間経過に伴う有意な変化は確認されたが,部屋間で有意差は認められなかった。作業効率として回答数と誤答率をみた結果,共に部屋間で有意差は認められず,部屋間での空間のイメージや作業開始前の快不快感の違いは二桁加算・減算の作業効率に影響を及ぼさない可能性が示唆された。

The effect of visual stimulation from room interiors with different wood quantities on task efficiency during two-digit addition and subtraction was investigated. Four actual-size model rooms of interiors constructed with different quantities of sugi (<i>Cryptomeria japonica</i> D.Don) wood were used for this experiment. Subjects were twelve healthy males and females comprised of university students and other adults. After resting for five minutes in the test rooms, the calculation tasks were performed for sixteen minutes. Changes in psychological evaluations and physiological response were measured before and after each task. Concerning room interior images, the “comfort” and “atmosphere” images were significantly different among the four rooms. The rating of a “comfortable” feeling before the task was significantly different among the four rooms. However, the “comfortable” feeling after the task was evaluated as “uncomfortable” in all rooms, and there was no significant difference among the four rooms. Salivary alpha-amylase showed significant differences among the time points, but there was no significant difference among the four rooms. The number of answers and percentage of incorrect answers as an index of task efficiency were not significantly different among the four rooms. This study suggested that task efficiency during two-digit addition and subtraction was not affected by the differences in “comfort” and “atmosphere” images or the “comfortable” feeling before the task in each room.
