Social preferences and lying aversion in children
研究7至14岁儿童的社会偏好发展是否伴随说谎行为变化，发现所有年龄段儿童都强烈厌恶说谎，说谎主要由自私和嫉妒驱动，社会偏好强的儿童更少欺骗，年龄大的儿童说谎更少且会自我合理化。
Abstract While previous research has shown that social preferences develop in childhood, we study whether this development is accompanied by reduced use of deception when lies would harm others, and increased use of deception to benefit others. In a sample of children aged between 7 and 14, we find strong aversion to lying at all ages. Lying is driven mainly by selfish motives and envy. Children with stronger social preferences are less prone to deception, even when lying would benefit others at no monetary cost. Older children lie less than younger children and use self-justification to lie.
