Authors of the knowledge gap hypothesis predicted television’s potential to narrow the gaps in some circumstances. This online experiment aimed to bound the conditions that facilitate the leveling role of audiovisual news for a foreign-born audience (N = 137) residing in the United States. Results showed that audiovisual news narrowed the gaps by improving learning for those who scored low on language or U.S. education and by attenuating improvements in learning for those with high language or education scores. Conversely, text news widened the gaps by sizable gains in learning for those with better language or more education.

语言技能、居住权和教育对移民新闻学习的调节作用

知识差距假说的作者预测了电视在某些情况下缩小差距的潜力。这个在线实验旨在为居住在美国的外国出生的观众 ( N = 137)确定促进视听新闻水平作用的条件。结果表明，视听新闻通过改善语言或美国教育得分低的人的学习以及削弱语言或教育得分高的人的学习改善来缩小差距。相反，文字新闻通过让语言更好或受教育程度更高的人在学习方面获得可观收益而扩大了差距。
