一些研究发现，边看电视边吃饭会增加食物摄入量，而另一些则不会。这种可变性中的一些可以反映正在观看的内容的真实性（即，内容）。为了测试这一点，我们通过操纵内容熟悉度来改变熟悉度。女学员参加了两次会议。在“不同”环节，他们观看了两集不同的喜剧《老友记》，第二集播放了零食。在“同一”环节，他们连续两次观看了另一集《老友记》，第二次重播时提供了零食。这里使用的三集《老友记》是完全平衡的，所以总体来说，“相同”和“不同”的唯一区别是第二集的内容是熟悉还是新奇。正如预期的那样，在“不同”的会议中少吃了14%，这表明相对于观看熟悉的内容，可能更吸引人的内容可以减少摄入量。这些发现与电视的刺激性可以不同地影响食物摄入的观点是一致的，尽管重复观看导致的无聊或易怒也可以解释这种影响。
Some studies find that eating with TV increases food intake while others do not. Some of this variability may reflect the engagingness of what is being watched (i.e., content). To test this we varied engagingness by manipulating content familiarity. Female participants undertook two sessions. In the “Different” session they watched two different episodes of the comedy Friends, with snack food presented during the second episode. In the “Same” session they viewed another episode of Friends twice in succession, with snack food presented during the second repeat showing. The three episodes of Friends used here were fully counterbalanced, so overall the only difference between the “Same” and “Different” sessions was whether the content of the second show was familiar or novel. As expected, 14% less was eaten in the “Different” session, suggesting that novel and presumably more engaging content can reduce intake relative to watching familiar and presumably less engaging content. These findings are consistent with the idea that the engagingness of TV can differentially affect food intake, although boredom or irritability resulting from repeat viewing might also explain this effect.
