Fourteen right-handed stutterers and 14 normal speakers (7 men & 7 women) responded to monaurally presented stimuli with their right and left hands. Results of an ANOVA with repeated measures showed that a significant ear-hand interaction existed in the normal subjects' data, with the right-ear, right-hand configuration producing the fastest responses. These findings were in concert with an efficiency model of neurolinguistic organization that suggests that the left hemisphere is dominant for language processing with the right hemisphere being capable of performing less efficient auditory-verbal analysis. Results of a similar ANOVA procedure showed that all main effects and interactions were nonsignificant for the stutterers. From these data a bilateral model of neurolinguistic organization was derived for the stutterers where both hemispheres must participate simultaneously in the decoding process. This held true regardless of sex or severity of stuttering.
14名右利手口吃者和14名正常说话者（7名男性和7名女性）用右手和左手对单耳呈现的刺激做出反应。重复测量方差分析的结果表明，正常受试者的数据中存在显著的耳-手交互作用，右耳-右手组合产生的反应最快。这些发现与神经语言组织的效率模型一致，该模型表明左半球在语言处理中占主导地位，而右半球能够进行效率较低的听觉-语言分析。类似方差分析程序的结果表明，口吃者的所有主效应和交互作用均不显著。从这些数据中得出了口吃者的双侧神经语言组织模型，即两个半球必须同时参与解码过程。无论口吃的性别或严重程度如何，都是如此。
