Hypothesis
Is there an association between the AVPR1A gene and altruistic behavior in preschoolers?
Conclusion
The study found that preschoolers carrying the AVPR1A RS3 'target allele' were less likely to engage in altruistic behavior.
Supporting Evidence
- The study is the first to show a genetic effect on altruistic behavior in preschoolers.
- Carriers of the AVPR1A RS3 'target allele' were four times less likely to donate more than one sticker chart.
- Previous research linked the AVPR1A gene to social behavior in adults.
Takeaway
The study shows that some kids are less likely to share their toys if they have a certain gene.
Methodology
The study used a modified dictator game to measure altruistic behavior in preschoolers and analyzed genetic data from twins.
Limitations
The sample size was relatively small, which may limit the generalizability of the findings.
Participant Demographics
Participants were 3.5-year-old twins, with a mix of males and females.
