本研究の目的は, 交通場面において不安全運転挙動を測定し, そのタイプを分類することである. 運転挙動に含まれる不安全挙動 (急加速, 急減速, 急旋回) を測定するためにセーフティー・カウンターが実験車内に設置された. 被験者として28名のプロのタクシードライバーが12カ月間にわたって本実験に参加した. 得られたデータを分析するために階層的クラスター分析法が採用された. 分析の結果から, 21名の安全群と7名の不安全群が分類された. 不安全群はさらに, その不安全挙動の特徴によって急加速型, 急減速型, 複合型に分類された.

The present study examined the recognition of numerical stimuli briefly presented in the peripheral and the central (foveal) visual fields of children with autism. The participants were 5 children with high-functioning Autism Spectrum Disorder (ASD) and 10 typically developing (TD) children of similar chronological age. The stimuli were number strings presented on a personal computer screen for 160 msec in the position of the fixation point (foveal condition) or in the peripheral visual field (retinal eccentricity of 16°) in one of the eight radial positions selected randomly (peripheral condition). The participants' task was to report the number of stimuli. The results showed that there were no significant differences in the mean response times between the TD and ASD groups. However, the mean percentage of correct answers in the ASD group was significantly higher than in the TD group for the peripheral condition. These results suggest that the effective visual field of the ASD group is expanded compared with the TD group. We discussed the relationships between perceptual characteristics and cognitive processes particular to ASD children.
