EEGs were recorded while 55 boys read and answered questions about passages. Concurrent validity between parietal alpha ratios obtained from these recordings and dichotic/dichhaptic scores supports their utility as measures of lateral processing. The evidence was particularly strong between right hand advantage for dichhaptically presented sequential patterns and left hemispheric activity while answering. Results also indicate that coefficients for dichotically presented digits and alpha ratios during silent reading are indices of receptive laterality and measure the deployment of lateral structures rather than degree of structural laterality. This supports a dynamic rather than static model of lateral processing during receptive language.
在55名男孩阅读并回答有关文章的问题时记录脑电图。从这些记录中获得的顶叶阿尔法比率与双耳分听/双手触觉得分之间的同时效度支持了它们作为侧化加工测量指标的效用。对于双手触觉呈现的序列模式的右手优势与回答问题时左半球活动之间的证据尤为有力。结果还表明，双耳分听呈现数字时的系数和默读时的阿尔法比率是感受性侧化的指标，并且测量的是侧化结构的部署而非结构侧化程度。这支持了接受性语言过程中侧化加工的动态而非静态模型。
