Midline crossing refers to behavior that results in reaching, stepping, or looking, across the body's midline. Several studies have indicated that infants, young children, and individuals with disability make more errors on midline-crossing tasks than on similar tasks placed at the ipsilateral side. Until recently, assessment of midline crossing has used a spatial protocol and has been criticized for not having a temporal component. The purpose of this study was to assess midline crossing by 9 4-yr.-old children within an information processing context. Analysis indicated that contralateral tasks required more processing time than similar tasks placed ipsilaterally.
中线交叉是指导致越过身体中线进行伸手、跨步或注视的行为。多项研究表明，婴儿、幼儿以及残疾个体在中线交叉任务上比在同侧进行的类似任务上犯的错误更多。直到最近，中线交叉的评估一直采用空间方案，并且因缺乏时间成分而受到批评。本研究的目的是在信息处理背景下评估9名4岁儿童的中线交叉情况。分析表明，对侧任务比同侧的类似任务需要更多的处理时间。
