Abstract We investigate how cognitive ability and age affect giving behavior in single-blind dictator game experiments with a sample comprising 514 non-student participants in Japan. First, we found a negative correlation between cognitive ability and giving behavior. Focusing on dictators with medium or low cognitive ability, the higher the cognitive ability, the lower are both giving probability and amount. Such a negative correlation was also found for dictators with high cognitive ability, but there was a jump increase in giving probability between the medium and high cognitive ability groups. Regarding the age effect, giving probability and amount of older dictators ( ≥ 40 years) were higher than those of younger dictators (20–29 years).

独裁者游戏实验中认知能力和年龄对给予的影响

摘要 我们在一个由 514 名日本非学生参与者组成的样本中研究了认知能力和年龄如何影响单盲独裁者游戏实验中的给予行为。首先，我们发现认知能力与给予行为之间存在负相关。专注于认知能力中等或低的独裁者，认知能力越高，给予概率和数量越低。对于具有高认知能力的独裁者也发现了这种负相关，但中等和高认知能力组之间的给予概率出现了跳跃式增加。关于年龄效应，老年独裁者（≥40岁）的给予概率和数量高于年轻独裁者（20-29岁）。
