边吃边看电视往往会增加食物摄入量，但为什么会发生这种情况尚不清楚。在这里，我们研究了电视对特定感官饱腹感（SSS）、内观（即饥饿/饱腹感）、情绪和其他变量的影响，研究对象是女性，她们吃一顿零食时看电视，另一顿不看电视。为了控制 SSS 的发展，参与者被分配到接受单一类型零食的一组或接受四种类型零食的一组。每个人都在看电视时吃得更多。在提供多种零食类型的组中，吃的食物种类更多。在边看电视边吃单一零食的组中，享乐评级表明 SSS 没有发展，这与更多的食物摄入量有关。无论哪个群体，与不看电视相比，看电视吃饭时必须消耗更多的食物才能产生同样的饥饿/饱腹感转变。如果电视能改善情绪并且参与者不熟悉电视节目，那么电视对食物摄入的影响较小，而如果参与者经常看电视，则影响更大。我们认为电视可以影响通常有助于自愿调节食物摄入的几个过程。 (C) 2014 Elsevier Ltd. 保留所有权利。
Watching television (TV) while eating tends to increase food intake, but why this occurs is not well understood. Here, we examined TV's effects on sensory specific satiety (SSS), introception (i.e., hunger/fullness), mood and other variables, in females who all ate one snack meal with TV and another without TV. To manipulate the development of SSS, participants were assigned either to a group receiving a single type of snack food or one receiving four types. Everyone ate more with TV. More food items were eaten in the group offered multiple snack types. In the group eating a single snack type with TV, hedonic ratings indicated that SSS did not develop and this was associated with greater food intake. Irrespective of group, more food had to be consumed to generate the same shift in hunger/fullness when eating with TV, relative to no TV. TV exerted less effect on food intake both if it improved mood and if participants were unfamiliar with the TV show, and a greater effect if participants were frequent TV viewers. We suggest that TV can affect several processes that normally assist the voluntary regulation of food intake. (C) 2014 Elsevier Ltd. All rights reserved.
