In the current study, we examined whether the quantity of toddlers' exposure to media was related to language skills and whether meeting the American Association of Pediatrics (AAP) recommendations of limiting media exposure to one hour or less per day was related to language skills. We examined these associations in a sample of toddlers (N = 157) living in low-income homes. Toddlers were about two years of age (M = 28.44 months, SD = 1.48 months) during the first visit when parents reported on toddlers' exposure to media in the home. Toddlers were about three years of age (M = 33.61 months, SD = 1.06 months) during the second visit when direct measures of toddlers' expressive and receptive language and receptive vocabulary skills were completed. Controls were child gender, race, mothers' education, marital status, work status, and center-based child care. Results indicated that more frequent exposure to media was related to lower expressive language, but not receptive language or receptive vocabulary. The predictor of AAP recommendation was not significantly related to any child language outcomes. These results suggest that media exposure may be related to the displacement of language-enhancing activities during a critical time for toddlers' language development. However, the AAP media recommendation of one hour may not be related to language development.
在当前的研究中,我们考察了幼儿接触媒体的数量是否与语言技能有关,以及是否符合美国儿科学会(AAP)的建议,即限制幼儿每天接触媒体的时间不超过一小时,这与语言技能有关。我们在一个生活在低收入家庭的幼儿样本(N=157)中检查了这些关联。在第一次访问中,当父母报告家中幼儿接触媒体的情况时,幼儿大约两岁(M=28.44 个月,SD=1.48 个月)。在第二次访问中,当完成对幼儿表达和接受语言以及接受性词汇技能的直接测量时,幼儿大约三岁(M=33.61 个月,SD=1.06 个月)。对照组为儿童性别、种族、母亲教育程度、婚姻状况、工作状况和以中心为基础的儿童保育。结果表明,更频繁地接触媒体与较低的表达性语言有关,但与接受性语言或接受性词汇无关。AAP 推荐的预测因素与任何儿童语言结果均无显著关系。这些结果表明,媒体接触可能与幼儿语言发展关键时期语言增强活动的替代有关。然而,AAP 媒体推荐的一小时可能与语言发展无关。
