Summary: This study found that the male hormone has a certain impact on women's emotional perception. Women are more likely to perceive neutral female faces as unhappy after exposure to the male hormone, and women in the ovulation phase are more likely to perceive anger from neutral female faces. However, this effect does not occur in the perception of male faces, or in the perception of sadness or sexual arousal from female faces.

Summary: Expectations can significantly influence decision-making in social interactions, with individuals more likely to forgive negative behaviors and reward positive behaviors from those who were expected to behave unfairly. These findings suggest that expectations of others' behavior and violations play a crucial role in subsequent allocation decisions.

Summary: The cultural values of individualism and collectivism have been shown to influence individuals' economic behavior. By priming participants with individualistic and collectivistic texts in a lab experiment, we examined their impact on allocation behavior in an ultimatum game and dictator game. The results showed that participants primed with collectivism displayed more altruistic allocation behavior and greater tolerance of unfair allocation behavior compared to those primed with individualism. Chinese participants influenced by collectivist values for a long time remained unaffected by the initiation of collectivism, but showed a shift in allocation behavior when individualism was primed.

Summary: In situations where resources are allocated, allocators often intentionally make advantageous unfair allocations, which may threaten their moral integrity. This study proposes that allocators interpret these allocations as less unfair to protect their own self-interest, allowing them to allocate unfairly. Through various experiments, the researchers consistently found that allocators perceived the unfair allocations as less unfair and this perception influenced their allocation decisions.

Summary: Previous research shows that women are alert to cognitive priming related to potential infidelity. This study explores whether women can be effectively primed to engage in competitor derogation, a strategy for intrasexual mating competition. The findings indicate that exposure to primes decreases women's ratings of photographed women and increases blame allocation.

Summary: Previous research has shown that delaying a reward in the dictator game leads to less generous offers, but did not fully confirm a significant relationship between temporal discounting and decision-making in games. Additionally, offers decrease with increasing social distance in both the dictator and ultimatum games, although social distance does not impact the accepted offer value in the ultimatum game.

Summary: This study investigated the effect of neuropeptide oxytocin on women's perceived attractiveness of flirtatious language. The results showed that oxytocin had opposite effects on the facial attractiveness ratings of men during fertile and luteal phases, and it also affected brain activity in regions associated with language processing and cognitive-emotional conflict.

Summary: The study examines how racial stereotypes in Brazil influence monetary allocations. Results show that Afro-Brazilians received larger transfers/offers in both games. The survey suggests that this is because they were perceived as having lower income levels and being in greater need of help.

Summary: This study investigates food sharing patterns and reactions to violations of food sharing norms among three societies in Tanzania (hunter-gatherers, pastoralists, and agriculturalists). The findings suggest that the type of economy and typical diet do not have an impact on food sharing behavior, but individual characteristics play a role in predicting food sharing behavior.
