Wow, that is quite confronting:
-
RESULTS. Only computer game playing resulted in significant reduced amounts of slow-wave sleep as well as significant declines in verbal memory performance. Prolonged sleep-onset latency and more stage 2 sleep were also detected after previous computer game consumption. No effects on rapid eye movement sleep were observed. Television viewing reduced sleep efficiency significantly but did not affect sleep patterns.
CONCLUSIONS. The results suggest that television and computer game exposure affect children’s sleep and deteriorate verbal cognitive performance, which supports the hypothesis of the negative influence of media consumption on children’s sleep, learning, and memory.
