The effect on the ability of children to attend to their school work, of the size of breakfast and whether a mid-morning snack had been consumed, was considered. Nine year old children were studied for four days. They reported what they had eaten for breakfast and days when they either had or had not eaten a mid-morning snack were contrasted. For an hour in the late morning, while performing individual work, activity sampling was used to establish the time spent on task. Those who had eaten a small breakfast, on average 61 kcal, spent significantly less time attending to their work than those who had eaten larger meals. The adverse effect of a small breakfast was reversed by the consumption of a mid-morning snack.
研究了早餐量的大小以及是否食用上午课间小吃对儿童完成学校作业能力的影响。对9岁儿童进行了为期四天的研究。他们报告自己早餐吃了什么，并对吃或没吃上午课间小吃的日子进行了对比。在上午晚些时候的一个小时里，孩子们进行个人作业时，采用活动抽样法来确定他们专注于任务的时间。那些早餐吃得少的孩子，平均摄入61千卡热量，他们专注于作业的时间明显少于那些吃得多的孩子。吃上午课间小吃可以扭转早餐量少所产生的不利影响。
