The Influence of Incidental Affect on Consumers’ Food Intake
研究发现，悲伤情绪下人们会吃更多享乐性食物（如爆米花），而快乐情绪下会吃更多非享乐性食物（如葡萄干），且营养信息能减弱这种效应。
Although incidental affect has been shown to influence both attitude and purchase behavior, it has not been extended to actual consumption. This research investigates whether specific affective states influence food consumption and whether this influence is moderated by factors such as information and the nature of the product (hedonic versus less hedonic). The authors show that an integrative mood management and mood evaluation framework accounts for this relationship more effectively than a self-regulation explanation. A preliminary test and two lab studies show that people eat larger amounts of hedonic foods (buttered popcorn and M&M's) when they are in a sad state than when they are in a happy state and that this effect is attenuated when nutritional information is present. In contrast, they tend to eat larger amounts of a less hedonic product (raisins) when they are in a happy state than when they are in a sad state. The authors discuss implications for responsible marketers, health professionals, and health conscious consumers in the context of campaigns and individual efforts.
