• 关键词: Right-hemisphere symptoms; Left unilateral spatial neglect; Rehabilitation; Indifferent attitude; Assessment; Generalized attentional deficits

Patients with left unilateral spatial neglect often show attitude indifferent to their difficulties. They are euphoric and react superficially. By the attitude, they are poorly motivated and tend to fall down. Consequently, they receive little benefit from rehabilitation, even if neglect is not severe. It is necessary to have adequate measurement for the symptoms that obstruct effective rehabilitation, but no objective assessment has been available.The main purpose of the research is to develop assessments for the right-hemisphere symptoms. Several assessments have been designed during the term of the project. The first assessment is unique in a way that adopts the method of conventional testing for unilateral spatial neglect but yet aimed at exploring patients' generalized attentional deficits. The second one focuses on errors in writing, especially on duplication and omission errors of continuous similar strokes. The final assessment consists of five tests for selective and sustained attention. Subjects were requested to respond to the target or imitate experimenter's performance presented visually or orally. It is suggested that patients with the right-hemisphere symptoms have non-spatial generalized attentional deficits that are assessable by the measurements we have developed. On the other hand, deficits of spatial attention result in unilateral spatial neglect. Each assessment was developed according to the research plan.As we expected, it was difficult to compare the performance of the left and right brain-damaged patients by the same assessments, since the former group of patients perform better on visual tasks and worse on verbal tasks than the latter group of patients. Nevertheless, the purpose of the research is almost achieved by elaboratedly designed methods of stimulus presentation and response, which is described above. Further study is expected with increased number of subjects.

左侧空间忽略患者常表现出对困难漠不关心的态度。他们很兴奋，反应很肤浅。从态度上看，他们的积极性很低，容易摔倒。因此，他们从康复中得到的好处很少，即使忽视并不严重。有必要对阻碍有效康复的症状进行适当的测量，但没有客观的评估方法，本研究的主要目的是开发右半球症状的评估方法。在项目期间设计了若干评估。第一个评估是独特的方式，采用传统的单侧空间忽略测试的方法，但旨在探索患者的广义注意力缺陷。第二类是书写错误，特别是连续相似笔画的重复和省略错误。最后的评估包括选择性和持续注意力的五个测试。被试被要求对目标做出反应或模仿实验者的视觉或口头表现。这表明，右半球症状的患者有非空间的广义注意力缺陷，我们已经开发的测量评估。另一方面，空间注意缺陷导致单侧空间忽视。每项评估都是根据研究计划制定的，正如我们所料，很难用同样的评估来比较左脑和右脑受损患者的表现，因为前一组患者在视觉任务上的表现优于后一组患者，而在语言任务上的表现则较差。尽管如此，研究的目的几乎是通过精心设计的刺激呈现和反应的方法来实现的，这是上面描述的。随着受试者数量的增加，预计将开展进一步研究。
