背景-目标：当垂直线位于页面中心的上方或下方时，线平分偏向页面中心，这表明页面的边缘分散了对线的注意力。字母字符行（LCL）平分需要全局和焦点注意力，以确定最接近行中心的目标字母。如果更多的焦点和更少的全局注意力被分配给LCL，则更多的全局注意力资源可能是可用的并且被无意地分配给页面。或者，如果分配的焦点注意力的LCL抑制全球注意力processing，可能会有较少的分心page.Method：24个健康成年人（12岁）平分垂直固体和字符线居中，或定位更接近顶部或底部的page.Results：有没有什么区别平分固体和字符线居中的页面。与页面相关的偏差是更大的字符线比实线平分，更大的线定位在顶部比底部的页面。随着线定位朝向顶部，老年参与者的尝试平分高于那些年轻的participator.Conclusions：这些结果表明，分配的焦点注意力增加全球注意力分散和全球背景的注意力分散是更大的垂直线放置在页面的上部。年龄较大的参与者似乎不太分心时，行被放置在页面的顶部，但这种年龄差异的原因需要进一步研究。
Background–objectives: When vertical lines are positioned above or below the center of the page, line bisection deviates toward the center of the page, suggesting that the edges of the page distract the allocation of attention to the line. A letter-character line (LCL) bisection requires both global and focal attention, to identify the target letter closest to the line’s center. If more focal and less global attention is allocated to a LCL, more global attentional resources may be available and inadvertently allocated to the page. Alternatively, if the allocation of focal attention to a LCL inhibits global attentional processing, there may be less distraction by the page.Method: Twenty-four healthy adults (12 older) bisected vertical solid and character lines centered, or positioned closer to the top or bottom of the page.Results: There was no difference between bisection of solid and character lines centered on the page. Page-related deviations were greater with character lines than solid line bisections, and greater for lines positioned toward the top than the bottom of the page. With lines positioned toward the top, the older participants’ attempted bisections were higher than those of the younger participants.Conclusions: These results suggest that the allocation of focal attention increases global attentional distractibility and that global-background attentional distraction is greater when the vertical lines are placed in the upper part of the page. Older participants appeared to be less distracted when lines were placed toward the top of the page, but the reason for this age difference requires further research.
