A Quasi-Experiment Assessing the Effectiveness of TV Advertising Directed to Children
利用魁北克省禁止儿童电视广告的法律，比较英语和法语儿童接触美国电视广告的差异，发现广告增加了儿童对玩具和谷物的认知与拥有。
A Quebec low eliminating advertising to children on Quebec TV stations left American border TV stations as the only source of TV commercials for toys and children's cereals. As a result, English-speaking children in Montreal who watch more children's TV on American stations were exposed to more advertising than French-speaking children who watch more children's TV on French-language Quebec stations. This situation facilitated the structuring of a quasi-experimental design comparing the two groups of children. As expected, English-speaking children were able to recognize significantly more toys available in the marketplace and reported having more children's cereals in their homes than did French-speaking children. Correlational analyses within each language group helped confirm the role of exposure to American TV (and hence of the Quebec law) as the probable cause of the observed differences.
