Hypothesis
Does allelic variation in 5-HTTLPR influence individual reactivity to social reward and punishment in rhesus macaques?
Conclusion
Genetic variation in serotonin function contributes to social reward and punishment in rhesus macaques, influencing their social behavior.
Supporting Evidence
- S/L monkeys spent less time looking at faces compared to L/L monkeys.
- S/L monkeys required juice payment to view photos of high status males.
- L/L monkeys exhibited risk-seeking behavior when primed with high status images.
Takeaway
Some monkeys react differently to social situations based on their genes, which affects how they feel about rewards and punishments.
Methodology
The study involved three experiments measuring eye gaze patterns, pupil diameter, and risk-taking behavior in male rhesus macaques based on their serotonin transporter genotype.
Potential Biases
Potential bias due to the small number of subjects and their relatedness from different breeding facilities.
Limitations
The small sample size may limit the generalizability of the findings.
Participant Demographics
Nine adult male rhesus macaques aged 4 to 10 years.
