在看电视的时候吃东西会增加食物的摄入量，部分原因是看电视会分散注意力。人们还知道，增强对最近吃过的食物的特定属性的记忆会减少随后的食物摄入量。由于编码时的分心会干扰记忆的形成，我们预测午餐时看电视会增加下午零食的摄入量，因为对最近进食的记忆受损。采用重复测量的设计，16名年轻的女本科生参观了实验室吃固定的午餐，无论是在看电视或在没有电视。当天下午晚些时候的品尝会上，研究人员测量了饼干的摄入量，参与者回忆了吃午餐的情况，并对记忆的生动程度进行了评级。所有参与者都吃了所有的午餐，午餐期间的食欲并没有因条件而异。参与者吃了更多的饼干后，他们吃了午餐，而看电视比当他们吃了午餐，而不看电视，这种效果不能归因于收视率的情绪或食欲前小吃会议的影响看电视。吃午餐时看电视也会降低午餐记忆的生动度。这些结果表明，看电视对食物摄入量的影响超出了看电视的时间，影响了随后的消费。他们进一步指出，这种影响可能与看电视对膳食记忆编码的影响有关。(c)2008爱思唯尔有限公司保留所有权利。
Eating while watching television has been shown to increase food intake in part due to the distracting effects of television viewing. It is also known that enhancing memory for the specific attributes of foods eaten in the recent past decreases subsequent food intake. Because distraction at the time of encoding interferes with memory formation, we predicted that television watching during lunch would increase afternoon snack intake due to impaired memory for recent eating. Using a repeated-measures design, 16 young women undergraduate students visited the laboratory to eat a fixed lunch either while watching television or in the absence of television. Intake of cookies at a tasting session later that afternoon was measured and participants recalled eating the lunch and rated the memory for vividness. All participants ate all of the lunch and rated appetite during lunch did not differ according to condition. Participants ate significantly more cookies after they had eaten their lunch while watching television than when they had eaten their lunch while not watching television and this effect could not be attributed to an effect of television watching on rated mood or appetite before the snack session. Watching television while eating lunch was also associated with reduced vividness ratings of the memory of the lunch. These results, suggest that the effects of television watching on food intake extend beyond the time of television watching to affect subsequent consumption. They further suggest that this effect may be related to an effect of television watching on encoding of the memory of the meal. (c) 2008 Elsevier Ltd. All rights reserved.
