Pairs of consonant-vowel (CV) syllables were dichotically presented to a large sample of healthy subjects (n = 263) who were instructed to monitor for the presence of a target CV (/ta/) which could occur in either ear. The subjects responded by pressing a response button, allowing the recording of reaction times (RTs) and number of correct responses. The investigated sample comprised consistent right-handers (CRH), consistent left-handers (CLH), and mixed-handers (MH). It was found that right-ear targets were detected more frequently and faster than left-ear targets, both in CRH and MH subjects. CLH subjects, on the other hand, responded faster to targets presented to the left ear but there was no ear advantage in terms of the correct responses. The RT data were used to examine whether they are compatible with the callosal relay model of language lateralisation. It was found that the predictions made by the callosal relay model were supported by the RT data for all groups.
将成对的辅音-元音(CV)音节以双耳分听的方式呈现给一大群健康受试者(n = 263),并指示他们监测目标CV(/ta/)的出现,目标CV可能出现在任一只耳朵中。受试者通过按下响应按钮进行反应,从而记录反应时间(RTs)和正确反应的次数。被调查的样本包括惯用右手者(CRH)、惯用左手者(CLH)和双手混用者(MH)。结果发现,在CRH和MH受试者中,右耳目标的检测频率更高、速度更快。另一方面,CLH受试者对左耳呈现的目标反应更快,但在正确反应方面没有耳优势。利用反应时间数据来检验它们是否与语言侧化的胼胝体中继模型相符。结果发现,胼胝体中继模型所做的预测得到了所有组反应时间数据的支持。
