关于获得性阅读障碍，即深度阅读障碍的正确解释，有两种观点：(A)它代表着左脑多重受损的阅读系统；(B)它代表着广泛依赖右脑拼写和语义加工的阅读。普赖斯、霍华德、帕特森、沃伯顿、弗里斯顿和弗拉科维亚克(1998)最近报道了一项脑成像研究，他们声称，这项研究的结果“排除了从纯粹的右脑文字处理的角度解释深度阅读障碍的可能性。”他们的说法与之前发表的工作的结论相冲突，后者强烈支持RH假说，但他们没有提到这一点。此外，我认为他们自己的结果也支持RH假说(尽管他们声称不是这样)；事实上，他们的结果允许提出比迄今可能的更详细的RH假说版本。因此，我得出结论，右脑对深度阅读困难的解释仍然是对深度阅读困难的首选解释。(C)2000年学术出版社。
Two views exist concerning the proper interpretation of the form of acquired dyslexia known as deep dyslexia: (a) that it represents reading by a multiply damaged left hemisphere reading system; (b) that it represents reading which relies extensively on right-hemisphere orthographic and semantic processing. Price, Howard, Patterson, Warburton, Friston, and Frackowiak (1998) have recently reported a brain-imaging study whose results, they claim, "preclude an explanation of deep dyslexia in terms of purely right-hemisphere word processing." Their claim conflicts with the conclusions of previous published work, which strongly supports the RH hypothesis, work which they do nor mention. Furthermore, I argue that their own results also favor the RH hypothesis (even though they claim otherwise); indeed, their results permit the formulation of a much more detailed version of the RH hypothesis than has hitherto been possible. Hence I conclude that the right hemisphere interpretation of deep dyslexic reading remains the preferred explanation of deep dyslexia. (C) 2000 Academic Press.
