Abstract
Used a probe-recognition short-term memory paradigm with 5 21-32 yr old males to study the precise effects of sleep deprivation on human memory. It was found that recognition performance, as measured by the sensitivity parameter d', was generally impaired for each S after 24 hrs of sleep deprivation. While d' decreased exponentially as the number of items intervening between the target and the probe increased, this decay rate was not affected by sleep loss. In addition there was confirmation of a previously observed increase in the positive skewness of reaction times after wakefulness. Data support the hypothesis that sleep deprivation increases the occurrence of lapses, periods of lowered reactive capacity, which prevent the encoding of items in short-term memory.
