This study investigated the hypothesis that background television affects interactions between parents and very young children. Fifty-one 12-, 24-, and 36-month-old children, each accompanied by 1 parent, were observed for 1 hr of free play in a laboratory space resembling a family room. For half of the hour, an adult-directed television program played in the background on a monaural television set. During the other half hour, the television was not on. Both the quantity and quality of parent-child interaction decreased in the presence of background television. These findings suggest one way in which early, chronic exposure to television may have a negative impact on development.
本研究旨在验证一个假设，即背景电视会影响父母与非常年幼的孩子之间的互动。研究人员观察了 51 名 12、24 和 36 个月大的儿童，每个孩子都由一位家长陪同，在一个类似于家庭房的实验室空间中自由玩耍 1 小时。在半小时的时间里，背景中会播放一个成人导向的电视节目，通过单声道电视播放。在另外半小时里，电视机关闭。研究发现，在有背景电视的情况下，父母与孩子的互动无论是数量还是质量都有所减少。这些发现表明，早期、长期接触电视可能会对儿童发展产生负面影响。
