A verbal dichotic test was given to 16 patients during right or left hemisphere narcosis induced by intracarotid barbiturate injection (Wada's procedure). During right hemisphere narcosis patients did not repeat left ear words. This demonstrates an intrahemispheric competition within the left hemisphere at the detriment of left ipsilateral ear words. After left dominant hemisphere narcosis, when aphasia had apparently disappeared, patients temporarily did not repeat right ear words. This suggests that, during this critical time period, two competitive processes took place. First the right hemisphere selected the left ear words by an intrahemispheric competition. Second it imposed them on the recovering left hemisphere at the detriment of right ear words, because of an interhemispheric competition.
对16名患者进行了言语双耳分听测试，测试是在通过颈动脉注射巴比妥酸盐诱导右半球或左半球麻醉期间（瓦达测试法）进行的。在右半球麻醉期间，患者不会重复左耳听到的单词。这表明左半球内存在半球内竞争，对左耳同侧单词不利。在左优势半球麻醉后，当失语症明显消失时，患者暂时不会重复右耳听到的单词。这表明，在这个关键时期，发生了两个竞争过程。首先，右半球通过半球内竞争选择了左耳单词。其次，由于半球间竞争，右半球将这些单词强加于正在恢复的左半球，对右耳单词不利。
