Recent research has shown that prism adaptation alleviates some of the symptoms of neglect. Although prism adaptation can aid patients with neglect, the mechanisms underlying these benefits remain largely unknown. One way in which prisms may work is by altering attentional orienting mechanisms known to be impaired in neglect. To investigate this hypothesis, we tested four right brain damaged patients (two with neglect) on a reflexive covert attention task before and after rightward prism adaptation and compared them with a group of healthy controls who underwent sham prism adaptation. Results demonstrated that rightward prism adaptation reduced both the rightward attentional bias, and the disengage deficit in patients with right brain damage irrespective of the presence of neglect.
最近的研究表明，棱镜适应可以减轻一些忽视症状。虽然棱镜适应可以帮助患有忽视症的患者，但这些益处背后的机制在很大程度上仍然未知。棱镜可能起作用的一种方式是通过改变已知在忽视症中受损的注意力定向机制。为了研究这一假设，我们在向右棱镜适应前后，对四名右脑损伤患者（两名患有忽视症）进行了一项反射性隐蔽注意力任务测试，并将他们与一组接受假棱镜适应的健康对照组进行了比较。结果表明，向右棱镜适应减少了右脑损伤患者的向右注意力偏差和脱离缺陷，无论是否存在忽视症。
