This paper re-examines two hypotheses on the ontogeny of hemispheric specialization that long ago fell into disfavor in neuropsychology. It is argued that these hypotheses, equipotentiality and progressive lateralization, may have suffered from misinterpretation that fostered premature acceptance of the developmental invariance view of hemispheric specialization. An alternative view is presented that incorporates both hypotheses within a neurodevelopmental context using anatomical (postmortem) and childhood aphasia data.
本文重新审视了两个关于半球特化个体发生的假说，这两个假说在很久以前就已在神经心理学中失宠。有人认为，这些假说，即等势性和渐进性侧化，可能因误解而受到影响，这种误解促成了对半球特化发育不变性观点的过早接受。本文提出了另一种观点，即在神经发育背景下，结合解剖学（尸检）和儿童失语症数据，纳入这两个假说。
