OBJECTIVE.电视和电脑游戏消费对大多数儿童的生活产生了强大的影响。以前的证据支持这样一种观点，即媒体曝光可能会损害各种行为特征。过度看电视和玩电脑游戏与许多精神症状有关，特别是情绪和行为症状，躯体主诉，注意力问题，如多动症，和家庭互动问题。然而，对于单一的过度媒体消费对睡眠模式的影响和对儿童的相关影响之间的关系，人们还缺乏足够的了解。本研究的目的是探讨单一的过度电视和电脑游戏消费对儿童的睡眠模式和记忆性能的影响。11名学龄儿童被招募进行多导睡眠图研究。孩子们自愿过度看电视和玩电脑游戏。在随后的夜晚，进行多导睡眠图测量以测量睡眠结构和睡眠连续性参数。此外，在媒体刺激之前和随后的睡眠期之后进行视觉和文字记忆测试，以确定视觉空间和文字记忆表现。只有玩电脑游戏会导致慢波睡眠的显著减少，以及非文字记忆能力的显著下降。在之前的电脑游戏消费之后，也检测到睡眠开始潜伏期延长和第二阶段睡眠更多。未观察到对快速眼动睡眠的影响。看电视显著降低睡眠效率，但不影响睡眠模式。结果表明，电视和电脑游戏的曝光影响儿童的睡眠和恶化的言语认知性能，这支持了媒体消费对儿童的睡眠，学习和记忆的负面影响的假设。
OBJECTIVE. Television and computer game consumption are a powerful influence in the lives of most children. Previous evidence has supported the notion that media exposure could impair a variety of behavioral characteristics. Excessive television viewing and computer game playing have been associated with many psychiatric symptoms, especially emotional and behavioral symptoms, somatic complaints, attention problems such as hyperactivity, and family interaction problems. Nevertheless, there is insufficient knowledge about the relationship between singular excessive media consumption on sleep patterns and linked implications on children. The aim of this study was to investigate the effects of singular excessive television and computer game consumption on sleep patterns and memory performance of children.METHODS. Eleven school-aged children were recruited for this polysomnographic study. Children were exposed to voluntary excessive television and computer game consumption. In the subsequent night, polysomnographic measurements were conducted to measure sleep-architecture and sleep-continuity parameters. In addition, a visual and verbal memory test was conducted before media stimulation and after the subsequent sleeping period to determine visuospatial and verbal memory performance.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.
