性别差异视角下中国家庭食物浪费行为的神经机制研究

“男主外、女主内”的中国传统家庭模式使得女性在家庭生活中占据主导地位,因此,国内女性食物浪费行为对防止家庭食物浪费起决定性的作用。本文基于双系统理论,通过事件相关电位实验从认知神经科学的角度测度不同性别群体的食物浪费程度,并探究影响不同性别群体食物浪费程度的关键因素。结果表明：（1）不同性别实验参与人均出现了明显的N270脑电成分,表明其食物浪费程度均较高,且女性比男性表现出了更明显的食物浪费倾向;（2）相对于90后与00后,50后与60后女性消费者面对食物倒掉刺激材料能诱发更为显著的N270,即年长女性的食物浪费水平显著低于年轻女性;（3）与女性相比,提高男性的节约意识对于减小其食物浪费意愿的作用更为明显。本文以期从性别特征角度为《反食品浪费法》的高效实施提供理论支持。

The neural mechanism of food waste behavior in Chinese households from the perspective of gender differences

The traditional Chinese family pattern of "the man goes out to work while the woman looks after the household" makes women play a dominant role in family life, so female food waste behavior plays a decisive role in preventing family food waste. Based on the dual-system theory, this paper measures the degree of food waste in different gender groups from the perspective of cognitive neuroscience through event-related potential experiments, and explores the key factors affecting the degree of food waste. The results showed that: (1) There were obvious N270 EEG components in the participants of different genders, indicating that the degree of food waste was higher, and generally, women tend to waste more food than men. (2) Compared with the younger generations, the food waste level of the women who were born in the 1950s and 1960s was significantly lower. (3) Compared with women, men should improve their awareness of saving food, which has a more significant effect on reducing a waste of food. The purpose of this study is to provide theoretical support for the effective implementation of the Anti-food Waste Law from the perspective of gender characteristics.
