Baekeland and Hartmann report that the “short sleepers” had been more or less average in their sleep needs until the men were in their teens. But at about age 15 or so, the men voluntarily began cutting down their nightly sleep time because of pressures from school, work, and other activities. These men tended to view their nightly periods of unconsciousness as bothersome interruptions in their daily routines.
　　In general, these “short sleeps” appeared ambitious, active, energetic, cheerful, conformist(不动摇) in their opinions, and very sure about their career choices. They often held several jobs at once, or workers full-or part-time while going to school. And many of them had a strong urge to appear “normal” or “acceptable” to their friends and associates.
　　When asked to recall their dreams, the “short sleepers” did poorly. More than this, they seemed to prefer not remembering. In similar fashion, their usual way of dealing with psychological problems was to deny that the problem existed, and then to keep busy in the hope that the trouble would go away.
　　The sleep patterns of the “short sleepers” were similar to, but less extreme than, sleep patterns shown by many mental patients categorized as manic(疯人).
　　The “long sleepers” were quite different indeed. Baekeland and Hartmann report that these young men had been lengthy sleeps since childhood. They seemed to enjoy their sleep, protected it, and were quite concerned when they were occasionally deprived of their desired 9 hours of nightly bed rest. They tended to recall their dreams much better than did the “short sleepers.”
　　Many of the “long sleepers” were shy, anxious, introverted (内向), inhibited (压抑), passive, mildly depressed, and unsure of themselves (particularly in social situations). Several openly states that sleep was an escape from their daily problems.

　　贝克尔和哈特曼报道说，“睡眠少的人”在未进入少年期之前，其正常睡眠时间大致与所需要的时间差不多。但到了15岁左右，由于学校、工作或其它活动的地压力，他们就故意地减少了夜间睡眠的时间。这些人持有这样的观点：夜间睡眠是一件令人讨厌的事情，打断了日常事务。
　　总的说来，这些“睡眠少的人”表现得雄心勃勃、积极活跃、精力充沛、无意识乐观豁达、立场坚定，对自己职业的选择胸有成竹。他们往往同时从事几项工作，或者一边上学读书，一边从事专职或兼职工作。其中许多人有强烈愿望，想在朋友和熟人面前表现得“正常”或“合群”。
　　当让他们回忆梦境时，“睡眠少的人”回忆不起什么来。更有甚者，他们似乎情愿什么都记不住。类似的情况是他们通常处理心理问题的方式：不承认问题的存在，希望只要忙忙碌碌，麻烦总会过去的。
　　“睡眠少的人”的睡眠模式与被划入疯子之类精神病患者的睡眠模式十分相似，只不过没有那么严重而已。
　　“睡眠多的人”情形则大不相同。贝克尔和哈特曼报道说，这些年轻人从小的，有抱负的睡眠就一直很长。他们好像注重睡眠，不让睡眠受打搅。偶尔没有所需的9个小时夜间卧床休息，他们便会十分不安。他们比“睡眠少的人”要更能回忆得起梦的内容。许多“睡眠多的人”腼腆、焦躁、内向、压抑、消极和稍微有点儿沮丧，尤其在社交场合缺乏自信。好几个人坦言，睡眠是摆脱每天烦恼的一种方式。
