Abstract

BACKGROUND/AIMS: Visual functions of neurologically impaired children with permanent cerebral visual impairment (CVI) can be difficult to determine. This study investigated the behavioural profile of CVI children by means of ethological observations in order to gain a better understanding of their visual functions.

METHODS

Video registrations of nine subjects who were unable to undergo more orthodox methods of visual function testing were observed and analysed by an ethologist.

RESULTS

A series of behaviours (direct signs) and supportive or confirming behavioural elements (indirect signs) indicating some visual perception in the children were found.

CONCLUSION

Detailed ethological observations of visual behaviour were shown to be useful for analysing visual functions of children with permanent CVI.

摘要

背景/目的:患有永久性脑性视觉障碍(CVI)的神经功能受损儿童的视觉功能可能难以确定。本研究通过行为学观察来调查CVI儿童的行为特征,以便更好地了解他们的视觉功能。

方法

一名行为学家对九名无法采用更传统视觉功能测试方法的受试者进行了视频记录观察和分析。

结果

发现了一系列表明儿童有一定视觉感知的行为(直接征象)以及支持或证实的行为要素(间接征象)。

结论

对视觉行为进行详细的行为学观察被证明有助于分析患有永久性CVI儿童的视觉功能。
