Abstract: 脳血管障害患者を対象に視覚探索課題を用いて前注意過程と集中注意過程及び呈示刺激ゼロの時の反応時間を検討した.また,同様の方法で右脳損傷患者と左脳損傷患者の差についても検討した.その結果,前注意過程と集中注意過程は健常者とほぼ同程度に機能していたが,呈示刺激ゼロの時の反応時間が有意に遅延し,視覚性末梢の情報処理過程が障害されていると示唆された.また,右脳損傷患者は,左脳損傷患者と比較し呈示刺激ゼロの時の反応時間が有意に遅延し,視覚性末梢の情報処理過程が障害されていると示唆された.このことより,右脳が視覚性末梢の情報処理過程により深く関与している可能性が推察された. / We studied the investigated preattentive, focal attentional processes and the reaction time of presents stimulus on zero points in the stoke patients by the visual search task, and investigated difference between damage right and left brain with same method. The results indicated that the stroke patients and control showed normal function in the preattentive and focal attentional processes. However, the reaction time of presents stimulus on zero points showed delay in stoke patients, therefore visual peripheral processing were disordered. The patients with damage in the right brain showed significantly the delay in the reaction time of stimulus on the zero point compared with those in the left brain, therefore visual peripheral processing were disordered. We concluded the right brain play the more important role in the visual peripheral processing than left.
