To examine whether children between 12 and 25 months of age learn words from an infant-directed DVD designed for that purpose.
Half of the children received a DVD to watch in their home over the course of 6 weeks.
All participants returned to a laboratory for testing on vocabulary acquisition every 2 weeks.
Ninety-six 12- to 24-month-old children.
Baby videos.
Parent report and observational measures of vocabulary acquisition related to words highlighted in the DVD; parent report of general language development; and parent report of children's media use.
The age at first viewing of baby DVDs was related to children's general language development. There was no evidence of learning words highlighted in the infant-directed DVD independent of parental intervention.
Researchers should continue to examine whether infant-directed media are effective in teaching infants and toddlers content and consider the cognitive factors related to whether very young viewers should be expected to learn from a DVD.
研究12至25个月大的儿童是否能从专门为此设计的婴幼儿DVD中学到单词。
一半儿童在6周内收到一张DVD在家观看。
所有参与者每2周返回实验室进行词汇习得测试。
96名12至24个月大的儿童。
婴儿视频。
与DVD中突出显示的单词相关的词汇习得的家长报告和观察指标；一般语言发展的家长报告；以及儿童媒体使用情况的家长报告。
首次观看婴儿DVD的年龄与儿童的一般语言发展有关。没有证据表明在没有家长干预的情况下，儿童能从婴幼儿DVD中学到突出显示的单词。
研究人员应继续研究婴幼儿媒体在教授婴幼儿内容方面是否有效，并考虑与是否期望非常年幼的观众从DVD中学到知识相关的认知因素。
