Purpose:
Childhood environments have an impact on an individuals' behavior and cognition. We explored the relationship and possible mechanisms between childhood environmental unpredictability (CEU) and prosocial behavior (PSB) in adults.
Participants And Methods:
We recruited Chinese college students (N = 1035) and adopted a questionnaire survey and structural equation modeling.
Results:
The results showed that CEU negatively predicted PSB in adults. Life-history strategy and dark personality chains mediated this relationship. Higher CEU facilitated faster development of life-history strategies in individuals, and dark personalities, via fast life-history strategies, further influenced PSB in adults. The mediating pathways of Machiavellianism, narcissism, and sadism were significant, while psychopathy was not. Women were more prosocial than men, and there was no sex difference in the influence mechanism of CEU on PSB.
Conclusion:
This study has practical significance as it emphasizes the importance of shaping a stable childhood environment and that individuals' prosociality can be improved by intervening in the mediation.
