Recall of a short story is ordinarily the same whether it is heard in the left, right, or both ears. It has been reported that many patients with severe cerebral dysfunctions (including brain damage, major psychiatric disorders, and learning disabilities in children) perform much better with one ear than the other (monaural asymmetry) and that binaural performance is worse than with the better ear alone (binaural interference). Blocking the poorer ear with an earplug is said to significantly improve speech comprehension in daily life. Because of the theoretical and practical significance of these reports, we have attempted a replication. We studied patients with anterior temporal lobectomy because it was proposed that the underlying mechanism of monaural asymmetry and binaural interference in all clinical categories may involve temporal lesions or abnormal inhibition of one temporal lobe by the other. We were unable to confirm the previous reports.
通常情况下,无论一个短篇小说是通过左耳、右耳还是双耳听到的,回忆起来都是一样的。据报道,许多患有严重脑功能障碍的患者(包括脑损伤、重度精神疾病以及儿童学习障碍)用一只耳朵听比用另一只耳朵听表现要好得多(单耳不对称),并且双耳听的表现比只用较好的那只耳朵听要差(双耳干扰)。据说在日常生活中,用耳塞堵住较差的那只耳朵能显著提高言语理解能力。由于这些报告具有理论和实际意义,我们尝试进行了重复研究。我们对接受颞叶前部切除术的患者进行了研究,因为有人提出,所有临床类型中的单耳不对称和双耳干扰的潜在机制可能涉及颞叶病变或一个颞叶对另一个颞叶的异常抑制。我们无法证实先前的报告。
