Behavioral results by task and sex. (A) We tested the correlation between fair beliefs and fair behavior. The X-axis represents the average transfers of each participant made by participants in the V, P, and VP conditions, while the Y-axis represents the participant’s benchmark of perceived fairness. (B) The average transfers were displayed for each condition by broken down by sex. (C) The response times (RT) of each condition were also displayed by categorizing by sex. It is important to note that confidence bounds around regression lines reflect a 95% confidence interval, and error bars represent standard deviation. Additionally, significance levels are indicated by asterisks (^*P < 0.05, ^**P < 0.01, ^***P < 0.001).
