Schalling-Sifneos and MMPI Alexithymia Scales were used to screen 730 Japanese subjects. The 27 subjects scoring highest and the 26 scoring lowest on both scales were designated high and low alexithymic respectively. The two groups were tested by tachistoscopically presenting them with a lateralized visual matching task, which incorporated both linguistic and nonlinguistic stimuli. Differences in ipsilateral and contralateral hand reaction times were used as an indicator of callosal transfer speed. The results indicated that the two groups did not differ in the callosal transfer of linguistic information. They differed significantly, however, in the right to left hemisphere transfer of nonlinguistic information. This result is suggestive of a physiological basis in alexithymia.
使用沙林-西夫neos量表和明尼苏达多项人格调查表（MMPI）的述情障碍量表对730名日本受试者进行筛查。在这两个量表上得分最高的27名受试者和得分最低的26名受试者分别被指定为高述情障碍组和低述情障碍组。通过速示器向两组呈现一种包含语言和非语言刺激的侧化视觉匹配任务来对他们进行测试。同侧和对侧手反应时间的差异被用作胼胝体传递速度的指标。结果表明，两组在语言信息的胼胝体传递方面没有差异。然而，在非语言信息从右半球向左半球的传递方面，两组存在显著差异。这一结果提示述情障碍存在生理基础。
