The TV-viewing behavior of 99 families with young children was videotaped by automated time-lapse recording equipment placed in homes for 10-day periods. The 99 families comprised 460 individuals from infants to 62 years of age. Time-sample analyses of 4,672 hours of recordings indicated that the TV-viewing room contained no viewers 14.7% of the time that the TV was on. There were no age trends in time spent with television. Percent visual attention to television increased greatly across the preschool years, leveled off at about 70% during the school-age years, and declined in adulthood. Men looked at the TV more than women. There were no significant correlations between time spent with TV and percent of visual attention to TV. The increase in visual attention to television during the preschool years is consistent with the theory that TV program comprehensibility is a major determination of attention in young children.
通过放置在家庭中的自动延时记录设备，对99个有幼儿的家庭的电视观看行为进行了为期10天的录像。这99个家庭共有460人，年龄从婴儿到62岁不等。对4672小时录像的时间抽样分析表明，在电视开启的时间里，有14.7%的时间电视观看室里没有观众。看电视的时间没有年龄趋势。在学前阶段，对电视的视觉注意力百分比大幅增加，在学龄阶段稳定在70%左右，在成年期下降。男性看电视的时间比女性多。看电视的时间与对电视的视觉注意力百分比之间没有显著相关性。学前阶段对电视视觉注意力的增加与电视节目可理解性是幼儿注意力的主要决定因素这一理论相一致。
