People with homonymous hemianopia (HH) benefit from applying compensatory scanning behaviour that limits the consequences of HH in a specific task. The aim of the study is to (i) review the current literature on task-specific scanning behaviour that improves performance and (ii) identify differences between this performance-enhancing scanning behaviour and scanning behaviour that is spontaneously adopted or acquired through training.
The databases PsycInfo, Medline, and Web of Science were searched for articles on scanning behaviour in people with HH.
The final sample contained 60 articles, reporting on three main tasks, i.e., search ( = 17), reading ( = 16) and mobility ( = 14), and other tasks ( = 18). Five articles reported on two different tasks. Specific scanning behaviour related to task performance in search, reading, and mobility tasks. In search and reading tasks, spontaneous adaptations differed from this performance-enhancing scanning behaviour. Training could induce adaptations in scanning behaviour, enhancing performance in these two tasks. For mobility tasks, limited to no information was found on spontaneous and training-induced adaptations to scanning behaviour.
Performance-enhancing scanning behaviour is mainly task-specific. Spontaneous development of such scanning behaviour is rare. Luckily, current compensatory scanning training programs can induce such scanning behaviour, which confirms that providing scanning training is important.IMPLICATIONS FOR REHABILITATIONScanning behaviour that improves performance in people with homonymous hemianopia (HH) is task-specific.Most people with HH do not spontaneously adopt scanning behaviour that improves performance.Compensatory scanning training can induce performance-enhancing scanning behaviour.
患有同视性偏盲（HH）的人受益于应用补偿性扫描行为，这种行为可在特定任务中限制 HH 的后果。本研究的目的是：（i）综述关于提高绩效的特定任务扫描行为的现有文献；（ii）确定这种提高绩效的扫描行为与自发采用或通过训练获得的扫描行为之间的差异。
在 PsycInfo、Medline 和 Web of Science 数据库中搜索关于 HH 患者扫描行为的文章。
最终样本包含 60 篇文章，报告了三个主要任务，即搜索（ = 17）、阅读（ = 16）和移动（ = 14）以及其他任务（ = 18）。有 5 篇文章报告了两个不同的任务。特定的扫描行为与搜索、阅读和移动任务的任务表现相关。在搜索和阅读任务中，自发的适应与这种提高绩效的扫描行为不同。训练可以引起扫描行为的适应，提高这两个任务的绩效。对于移动任务，仅发现了关于对扫描行为的自发和训练诱导适应的有限信息。
提高绩效的扫描行为主要是特定于任务的。这种扫描行为的自发发展很少见。幸运的是，目前的补偿性扫描训练计划可以诱发这种扫描行为，这证实了提供扫描训练很重要。
提高同视性偏盲（HH）患者绩效的扫描行为是特定于任务的。大多数 HH 患者不会自发采用提高绩效的扫描行为。补偿性扫描训练可以诱发提高绩效的扫描行为。
