Neurologically healthy adults tend to display a reliable leftward perceptual bias during visuospatial tasks, a phenomenon known as pseudoneglect. However, the phenomenon in older adults is not well understood, and a synthesis of research that examines pseudoneglect using the line bisection task, as well as other tasks, in the context of aging is lacking. The aim of the current systematic review is to integrate the available research on pseudoneglect in late adulthood, and to discuss the association between age and a bias to the left hemispace. The systematic search revealed that five different tasks have been used to examine pseudoneglect in younger and older adults, and that participants over 60 years of age have demonstrated inconsistent perceptual biases (e.g., enhanced leftward bias, suppressed leftward bias, and rightward bias). Based on current evidence, although some age-related trends in the perceptual bias can be identified within each task, no firm conclusions about the effects of age on pseudoneglect can be drawn. A number of recommendations for future research are outlined throughout the review, including use of smaller age ranges within age groups, differentiating between neurologically healthy participants and those with clinical diagnoses, continued examination of gender, and consistent use of stimuli and methods of analyses within each task to improve internal comparability.

成人假牙的轨迹：系统评价

神经系统健康的成年人在视觉空间任务期间倾向于表现出可靠的向左感知偏差，这种现象被称为假忽视。但是，对老年人的现象还没有很好的理解，并且缺乏在衰老过程中使用线二等分任务以及其他任务来检查假性忽视的研究综合报告。当前系统评价的目的是整合关于成年后期假性忽视的现有研究，并讨论年龄与左半空间偏向之间的关联。系统的搜索显示，已经使用了五项不同的任务来检查年轻人和老年人中的假性忽视，并且60岁以上的参与者表现出不一致的知觉偏见（例如，左偏偏增强，左偏偏抑制和右偏偏）。根据目前的证据，尽管可以在每个任务中识别出一些与年龄相关的感知偏差趋势，但无法得出关于年龄对假性忽视影响的确切结论。整个审查概述了许多有关未来研究的建议，包括在年龄组内使用较小的年龄范围，区分神经系统健康的参与者和具有临床诊断的参与者，继续进行性别检查以及在每种方法中一致使用刺激和分析方法改善内部可比性的任务。
