We described disorders of a patient which were uniquely restricted to speech perception of syllable sequences after brain damage. The results of series of experiments using syllable sequences showed "negative recency effect," in which the subject's repetition performance at the latter syllable position was remarkably poor. Experimental analyses suggested that the "negative recency effect" could be due to dual factors: the lower rate of processing of speech sounds and the memory load of holding processes of preceding syllables imposed on the succeeding phonological processing. The results also suggested that the holding processes which imposed the memory load on the succeeding auditory phonological coding processing were modality nonspecific.
我们描述了一名患者的病症,这些病症在脑损伤后仅局限于对音节序列的语音感知。使用音节序列进行的一系列实验结果显示出“负近因效应”,即受试者在后面音节位置的重复表现明显较差。实验分析表明,“负近因效应”可能归因于双重因素:语音处理速率较低以及前序音节的保持过程对后续语音处理施加的记忆负荷。结果还表明,对后续听觉语音编码处理施加记忆负荷的保持过程是非模态特异性的。
