进一步探讨,我们以《自陈利他行为量表》的得分量化了参与者原始的利他倾向,与金额的数目、是否有压力作为自变量:以是否收下金钱,即是否做出利他选择为因变量,进行二元logistics回归分析。结果如下:霍斯默–莱梅肖检验显著性为0.221 > 0.05,模型与观察数据拟合良好,在进一步分析后得出《自陈利他行为量》表中的得分显著影响是否会做出利他行为(OR = 0.558, p = 0.002 < 0.05)得分越高,参与者越有可能拒绝收下,更可能做出利他的选择。金额大小对是否做出利他行为也具有显著影响(OR = 56.101, p = 0.004 < 0.05),表示金额越高,参与者越有可能收下,更可能做出利己的选择。社会压力同样对是否做出利他行为具有显著影响(OR = 0.558, p = 0.011 < 0.05),在存在社会压力的环境下,参与者更有可能拒绝收下,从而做出利他的选择。然而,仍然有部分参与者选择了保留所得,对于这些参与者来说,可能他们的利己欲望超过了利他和社会压力的综合作用。详见
