Previous research examining the relationship between television viewing and vocabulary has produced mixed findings that indicate the quality of television exposure may impact language development more than quantity. However, few infant or toddler studies have included both quality and quantity measures and no study has done so with bilinguals. Caregivers of monolingual English, monolingual French, and English-French bilingual infants and toddlers from the same geographical area completed questionnaires regarding television exposure and vocabulary. Factor analysis of the questionnaire data confirmed that quantity and quality of viewing should be assessed separately. Quantity of television viewing was not correlated with language outcomes in any group. Poor quality viewing (television unintended for children, background television, solitary viewing, and earlier age of viewing) was related to lower vocabulary scores overall, but especially the English vocabulary scores of bilingual toddlers. Possible reasons for this finding are discussed.
先前的研究考察了看电视与词汇量之间的关系，结果喜忧参半，这表明电视节目的质量可能比数量对语言发展的影响更大。然而，很少有针对婴儿或学步儿童的研究同时包含质量和数量方面的测量，也没有针对双语儿童的研究。来自同一地理区域的单语英语、单语法语和英法双语婴儿和学步儿童的照顾者完成了关于电视观看和词汇量的调查问卷。对问卷数据的因子分析证实，应分别评估观看的数量和质量。任何群体的电视观看量都与语言结果无关。不良的观看质量（不适合儿童的电视节目、背景电视、独自观看和较早的观看年龄）与整体较低的词汇分数有关，但对双语学步儿童的英语词汇分数影响尤其明显。对这一发现的可能原因进行了讨论。
