Transient nature of cooperation by pay-it-forward reciprocity
Humans often forward kindness received from others to strangers, a phenomenon called the upstream or pay-it-forward indirect reciprocity. Some field observations and laboratory experiments found evidence of pay-it-forward reciprocity in which chains of cooperative acts persist in social dilemma situations. Theoretically, however, cooperation based on pay-it-forward reciprocity is not sustainable. We carried out laboratory experiments of a pay-it-forward indirect reciprocity game (i.e., chained gift-giving game) on a large scale in terms of group size and time. We found that cooperation consistent with pay-it-forward reciprocity occurred only in a first few decisions per participant and that cooperation originated from inherent pro-sociality of individuals. In contrast, the same groups of participants showed persisting chains of cooperation in a different indirect reciprocity game in which participants earned reputation by cooperating. Our experimental results suggest that pay-it-forward reciprocity is transient and disappears when a person makes decisions repeatedly, whereas the reputation-based reciprocity is stable in the same situation
Preverbal infants expect agents exhibiting counterintuitive capacities to gain access to contested resources
Claims to supernatural power have been used as a basis for authority in a wide range of societies, but little is known about developmental origins of the link between supernatural power and worldly authority. Here, we show that 12- to 16-month-old infants expect agents exhibiting counterintuitive capacities to win out in a two-way standoff over a contested resource. Infants watched two agents gain a reward using either physically intuitive or physically counterintuitive methods, the latter involving simple forms of levitation or teleportation. Infants looked longer, indicating surprise, when the physically intuitive agent subsequently outcompeted a physically counterintuitive agent in securing a reward. Control experiments indicated that infants’ expectations were not simply motived by the efficiency of agents in pursuing their goals, but specifically the deployment of counterintuitive capacities. This suggests that the link between supernatural power and worldly authority has early origins in development
British Children’s and Adults’ Perceptions of Robots
Robotics and artificial intelligence (AI) systems are quickly becoming a familiar part of different aspects of everyday life. We know very little about how children and adults perceive the abilities of different robots and whether these ascriptions are associated with a willingness to interact with a robot. In the current study, we asked British children aged 4-to-13 years and British adults to complete an online experiment. Participants were asked to describe what a robot looks like, give their preference for various types of robots (a social robot, a machine-like robot and a human-like robot), and whether they were willing to engage in different activities with the different robots. Results showed that younger children (4 to 8 years old) are more willing to engage with robots compared to older children (9 to 13 years) and adults. Specifically, younger children were more likely to see robots as kind compared to older children and adults. Younger children were also more likely to rate the social robot as helpful compared to older children and adults. This is also the first study to examine preferences for robots engaging in religious activities and results show that British adults prefer humans over robots to pray for them but such biases may not be generally applicable to children. These results provide current insight into how children and adults in the United Kingdom accept the presence and function of robots
Night parade of one hundred demons: Exploring counterintuitiveness of Japanese monstrous beings
Minimally counterintuitive (MCI) theory has been proposed to explain common features inherent in supernatural, mythological, or religious concepts across diverse cultural traditions. According to this theory, these concepts often embody an optimal balance of counterintuitive elements, enhancing their cognitive attraction and likelihood of widespread transmission. Previous research has explored the prevalence of minimal counterintuitiveness in characters portrayed in various folkloristic and religious written materials. Here, we extend this investigation to examine the presence of minimal counterintuitiveness in yokai, Japanese monstrous beings. Using Barrett’s MCI coding scheme, we analyzed 54 unique entities described in “Yokai Zukan”, a compilation of four materials written before the Westernization of Japan. Our findings, in line with previous research, demonstrate that 92.5% of the entities exhibit a minimal number of counterintuitive traits. The result highlights the applicability of the MCI theory to the analysis of Japanese monstrous beings that were recorded in Japan before Westernization
Commitment-enhancing tools in Centipede games: Evidencing European–Japanese differences in trust and cooperation
Theories of trust
distinguish general trust in situations of social uncertainty from
assurance-based trust in committed, long-term relationships. This study
investigates European-Japanese differences using the Centipede game, in which
two players choose between cooperation and defection. The game models repeated
reciprocal interactions, necessitating assurance-based trust to sustain
cooperation. We included game conditions offering players the option of
purchasing commitment-enhancing tools to increase social certainty. Japanese
participants were more cooperative than Europeans, confirming higher
assurance-based trust, and also purchased more commitment-enhancing tools,
demonstrating their preferences for social certainty. Purchase of
commitment-enhancing tools improved cooperativeness in both groups. However, if
co-players refused tool purchase, the Japanese appeared to interpret this as
non-cooperative intent and cooperativeness in the respective games
decreased
