For adults,【C4】______between six and nine hours of sleep as a nightly average is not unusual, and 7.5 hours probably best expresses the norm. Such norms, of course, forms inevitably vary with the criteria of sleep employed. The most【C5】______and reliable figures on sleep time, including those cited here, come from studies in sleep laboratories, where EEG criteria are employed.

The newborn infant may spend an average of about 16 hours of each 24-hour period in sleep,【C7】______the sleep time drops sharply: by two years of age, it may【C8】______from nine to 12 hours. Decreases to approximately six hours have been observed among the elderly.
【C9】______will be discussed from below, EEG sleep studies have indicated that sleep can be considered to consist of several different stages. Developmental changes in the relative proportion of sleep time【C10】______in these sleep stages are as striking as age-related changes in total sleep time.
