There is little evidence that infants learn from infant-oriented educational videos and television programming. This 4-week longitudinal experiment investigated 15-month-olds' (N = 92) ability to learn American Sign Language signs (e.g., patting head for hat) from at-home viewing of instructional video, either with or without parent support, compared to traditional parent instruction and a no-exposure control condition. Forced-choice, elicited production, and parent report measures indicate learning across all three exposure conditions, with a trend toward more robust learning in the parent support conditions, regardless of medium. There were no differences between experimental and control conditions in the acquisition of corresponding verbal labels. This constitutes the first experimental evidence of infants' ability to learn expressive communication from commercially available educational videos.
几乎没有证据表明婴儿能从以婴儿为导向的教育视频和电视节目中学到东西。这项为期4周的纵向实验调查了92名15个月大婴儿学习美式手语（如拍头表示帽子）的能力，将在家观看教学视频（有无家长支持）的情况与传统家长指导及无接触对照组进行比较。强制选择、诱发产出和家长报告测量结果表明，在所有三种接触条件下婴儿都有学习，无论采用何种媒介，在有家长支持的条件下学习趋势更为明显。在相应语言标签的习得方面，实验组和对照组之间没有差异。这构成了婴儿从市售教育视频中学习表达性交流能力的首个实验证据。
