※ 글의 내용과 일치하지 않는 것은? [문 14～문 15] Any parent can tell you that infants find commercials more interesting to watch than actual shows. The reason? Commercials effectively grab children's attention by providing a rapid series of images that make the visual experience unusual. When producing commercials for TV, the content of the commercial is secondary to this well -crafted array of imagery. Each image lasts for at most a few seconds before being replaced by another exciting image to ensure our attention does not wander. This filming technique may well have significant adverse effects on viewers, especially children. Researchers have found that young children who watch TV often are more likely to develop low attention spans that can hinder learning later in life. Commercials may be one of the primary reasons why this happens.
