Previous investigations pointed to a relationship between hemispheric asymmetry and dream recall. Since handedness may reflect the extent to which cerebral organization is lateralized, it was hypothesized that differences in dream recall might exist between different handedness groups. A selected sample of 78 college students (38 right-handers, 25 left-handers, 15 mixed-handers) completed a seven-day sleep and dream diary upon final awakening, at home. Results showed that significantly more dreams are recalled by females compared to males and by right-handers compared to mixed-handers and left-handers. The latter finding is tentatively interpreted as due to a more direct access to aspects of oneiric material structured in the left hemisphere by right-handers, whose language centers are located in the same hemisphere. Unexplained findings of the only other investigation concerning handedness and sleep variables (Hicks, Pellegrini & Hawkins, 1979), which showed greater variability of sleep duration in mixed-handers, were not confirmed by the present study.
先前的研究指出了半球不对称与梦的回忆之间的关系。由于利手可能反映大脑组织的偏侧化程度，因此有人推测不同利手群体在梦的回忆方面可能存在差异。从78名大学生（38名右利手、25名左利手、15名混合利手）中选取的样本，在家中最后一次醒来时完成了一份为期七天的睡眠和梦的日记。结果显示，与男性相比，女性回忆起的梦明显更多；与混合利手和左利手相比，右利手回忆起的梦明显更多。后一个发现初步解释为，右利手的语言中枢位于同一半球，因此他们能更直接地接触到左半球构建的梦的素材。关于利手与睡眠变量的另一项研究（希克斯、佩莱格里尼和霍金斯，1979年）有一些无法解释的发现，该研究表明混合利手的睡眠时间变异性更大，但本研究并未证实这一点。
