Previous literature suggests that women evidence more bilateral cerebral organization, particularly in language processing, whereas men show greater left hemisphere dominance for language. This study examined the magnitude of these gender differences in a lateralized lexical decision task and the implications of such differences to semantic processing and cerebral organization. As predicted, women, as compared to men, recruited greater bilateral hemispheric resources, as evidenced by greater contralateral hemispheric priming. Spatial skills predicted less priming in women, but not in men. Implications for laterality research in aging populations as well as future directions are discussed.
以往文献表明,女性表现出更多的双侧大脑组织特征,尤其是在语言处理方面,而男性在语言方面则表现出更强的左半球优势。本研究在一项偏侧化词汇判断任务中考察了这些性别差异的程度,以及这些差异对语义处理和大脑组织的影响。正如预期的那样,与男性相比,女性调动了更多的双侧半球资源,对侧半球启动效应更强就证明了这一点。空间技能预示着女性的启动效应较小,但男性并非如此。本文还讨论了对老年人群体偏侧性研究的启示以及未来的研究方向。
