The present paper describes two experiments designed to investigate cognitive asymmetry after awakening from REM and NONREM sleep as a function of time after the awakening and handedness. Two groups of 9 right-handed male subjects each participated in the first experiment. Subjects were awakened from REM and NONREM sleep and after 35 min (Group 1), or 75 min (Group 2), tested on a 6-test battery designed to measure cognitive asymmetry. In contrast to our previous findings in subjects tested within 1-2 min after the awakening who showed a significant sleep-stage dependent shift in cognitive asymmetry, the present results did not show significant differences in performance between the two awakening conditions for any of the groups. Two groups of 12 male and 12 female left-handed subjects participated in the second experiment. All subjects were tested within 1-2 min after the awakenings from REM and NONREM sleep on the same 6-test battery as in experiment 1. Also in contrast to our previous findings in right handers, left-handers did not show any consistent shifts in cognitive asymmetry after the awakenings.
本文描述了两项实验，旨在研究从快速眼动（REM）睡眠和非快速眼动（NONREM）睡眠中醒来后的认知不对称性，该不对称性是觉醒后时间和利手的函数。每组9名右利手男性受试者参与了第一项实验。受试者从REM睡眠和NONREM睡眠中醒来，35分钟后（第1组）或75分钟后（第2组），接受一组6项测试，旨在测量认知不对称性。与我们之前在觉醒后1 - 2分钟内测试的受试者的研究结果相反，之前的研究结果显示认知不对称性存在显著的睡眠阶段依赖性变化，而本研究结果显示，对于任何一组，两种觉醒条件下的表现均无显著差异。每组12名男性和12名女性左利手受试者参与了第二项实验。所有受试者在从REM睡眠和NONREM睡眠中醒来后的1 - 2分钟内，使用与实验1相同的6项测试进行测试。同样与我们之前对右利手的研究结果相反，左利手在觉醒后并未表现出认知不对称性的任何一致变化。
