目的研究棱镜适应对忽略症各种症状的效应，包括主观中线病理性向右移。方法１１例忽略症病人采用两种测验来检测空间障碍棱镜适应的效应。实验１：命令病人在没有视觉反馈情况下用手指指向正前方评估棱镜适应效应。实验２：利用传统的神经心理学测验，测试忽略症的临床症状来评估棱镜的适应效应（平分直线、划掉试验、绘画、临摹及阅读）。结果所有暴露于使视野朝向右侧偏移的光学环境中的病人身体主观中线及神经心理测验均改善（两者Ｐ＜０．０５），这个现象一直持续到去掉棱镜２ｈ之后。结论提出有关棱镜适应后单侧忽略症的身体客观中线和常规神经心理测验之间关系问题。这两种评估肯定效应的再发现提出了想像空间（连接多种感觉整合）可以分为感觉—运动和更多认识功能两部分。因此棱镜适应可以为忽略症的自我参照中心及注意力的理论解释提出一个新的评估工具。
Objective To study the effects of prism adaptation on various symptoms of neglect, including subjective midline pathology to the right. Methods 11 cases of ignoring the disease used two kinds of tests to detect the effect of space obstacle prism adaptation. Experiment 1: The patient is instructed to assess the prism adaptation effect with his finger pointing straight ahead without visual feedback. Experiment 2: Assess the effect of prisms by using conventional neuropsychological tests to test the clinical symptoms of ignoring the disorder (bisecting lines, sketching, drawing, copying, and reading). Results All subjective midline and neuropsychological tests of patients exposed to an optical environment that shifted the field of view toward the right side improved (both P <0.05), and this phenomenon persisted until the prisms were removed for 2 h. Conclusion The relationship between the objective physical midline and conventional neuropsychological tests for unilateral negligence after prism accommodation is proposed. The rediscovery of these two evaluative positive effects suggests that imaginative space (connecting multiple sensory integration) can be divided into sensory-motor and cognitive functions. Prism adaptation can thus provide a new assessment tool for ignoring the self-referential center of the disorder and the theoretical explanation of attention.
