Event-related potentials (ERPs) were recorded from one midline and three pairs of homotopic lateral sites while subjects determined whether or not sequentially presented words rhymed. ERPs from 11 left-handed males with a family history of sinistrality were compared with those from 12 right-handers, none of whom had such a family history. As in previous work (e.g. Rugg, M. D. Neuropsychologia 22, 435-443, 1984) the slow negative wave developing during the interval in which subjects waited for the final word was more negative from left-hemisphere electrodes, and the rhyme/non-rhyme differences in the ERPs following this word were greater over the right hemisphere. Neither of these asymmetries differed between the left and right-handers. Possible reasons for the occurrence of these ERP asymmetries during rhyme-matching are discussed, and it is suggested that the aspect(s) of linguistic processing tapped by this task, and influencing concurrently recorded ERPs, may be similarly lateralised in the brains of left- and right-handers.
在受试者判断依次呈现的单词是否押韵时，从一个中线部位和三对同位侧方部位记录事件相关电位（ERP）。将11名有左利手家族史的左利手男性的ERP与12名无此家族史的右利手的ERP进行比较。正如之前的研究（如Rugg, M. D.《神经心理学》22, 435 - 443, 1984）所示，在受试者等待最后一个单词的间隔期间出现的慢负波，从左半球电极记录到的更为负向，并且在这个单词之后ERP中的押韵/不押韵差异在右半球更为明显。这两种不对称性在左利手和右利手之间并无差异。文中讨论了在押韵匹配过程中出现这些ERP不对称性的可能原因，并提出该任务所涉及的语言加工方面以及对同时记录的ERP产生影响的因素，在左利手和右利手的大脑中可能同样存在偏侧化。
