根据以下材料，回答 Baekeland and Hartmann report that the"short sleepers" had been more or less average in their sleep needsuntil the men were in their teens. But at about age 15 or so, the menvoluntarily began cutting down their nightly sleep time because of pressuresfrom school, work, and other activities. These men tended to view their nightlyperiods of unconsciousness as bothersome interruptions in their daily routines. In general, these "shortsleepers" appeared ambitious, active, energetic, cheerful, conformist in theiropinions, and very sure about their career choices. They often held severaljobs at once, or worked full-or part-time while going to school. And many ofthem 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 prefernot remembering.
