1. Meng, X., Nakawake, Y., Hashiya, K., Burdett, E., Jong, J., & Whitehouse, H. , Preverbal infants expect agents exhibiting counterintuitive capacities to gain access to contested resources. Scientific reports, 11(1), 1-10., Scientific reports, 11, 1, 1-10, 2021.05, 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..

KISHIMOTO, R., ITAKURA, S., FUJITA, K., HASHIYA, K., EVALUATION OF “CALCULATING” HELPERS BASED ON THIRD-PARTY OBSERVATION IN ADULTS AND CHILDREN. , Psychologia,, 2019-A008., 2020.05, In the context of reciprocity, behaving cooperatively only when it enhances one’s reputation is a strategy that brings reputational benefits at minimal cost; however, if other members of society notice an individual employing such a strategy, any accumulated positive reputation may be negated. The present study addresses the development of this social judgement by examining how preschoolers and adults evaluate agents with or without reputational management. We presented Public-only Helpers (cooperative only when they were seen) with Private-only Helpers (cooperative only when they were not seen) or Unconditional Non-Helpers (never cooperative regardless of being seen). Results showed that children less preferred Public-only Helpers presented with Private-only Helpers than with Unconditional Non-Helpers. Adults avoided Public-only Helpers irrespective of compared agents. Our findings indicate that although preschoolers’ evaluations of reputational management are not as salient as those of adults, they less prefer people who provide help to gain personal reputational benefits..
3. Xianwei Meng, Yo Nakawake, Hiroshi Nitta, Kazuhide Hashiya, Yusuke Moriguchi, Space and rank:
Infants expect agents in higher position to be socially dominant, Proceedings of the Royal Society B: Biological Sciences, 10.1098/rspb.2019.1674, 286, 1912, 2019.10, Social hierarchies exist throughout the animal kingdom, including among humans. Our daily interactions inevitably reflect social dominance relationships between individuals. How do we mentally represent such concepts? Studies show that social dominance is represented as vertical space (i.e. high = dominant) by adults and preschool children, suggesting a space-dominance representational link in social cognition. However, little is known about its early development. Here, we present experimental evidence that 12- to 16-month-old infants expect agents presented in a higher spatial position to be more socially dominant than agents in a lower spatial position. After infants repeatedly watched the higher and lower agents being presented simultaneously, they looked longer at the screen when the lower agent subsequently outcompeted the higher agent in securing a reward object, suggesting that this outcome violated their higher-is-dominant expectation. We first manipulated agents’ positions by presenting them on a podium (experiment 1). Then we presented the agents on a double-decker stand to make their spatial positions directly above or below each other (experiment 2), and we replicated the results (experiment 3). This research demonstrates that infants expect spatially higher-positioned agents to be socially dominant, suggesting deep roots of the space-dominance link in ontogeny..
4. Kazuhide Hashiya, Xianwei Meng, Yusuke Uto, Third-Party Attentional Relationships Affects Infants' Gaze Following: An Eye-Tracking Study., Frontier Psycholgy, 10.3389/fpsyg.2016.02065, 7, 2017.05, Not only responding to direct social actions toward themselves, infants also pay attention to relevant information from third-party interactions. However, it is unclear whether and how infants recognize the structure of these interactions. The current study aimed to investigate how infants' observation of third-party attentional relationships influence their subsequent gaze following. Nine-month-old, 1-year-old, and 1.5-year-old infants (N = 72, 37 girls) observed video clips in which a female actor gazed at one of two toys after she and her partner either silently faced each other (face-to-face condition) or looked in opposite directions (back-to-back condition). An eye tracker was used to record the infants' looking behavior (e.g., looking time, looking frequency). The analyses revealed that younger infants followed the actor's gaze toward the target object in both conditions, but this was not the case for the 1.5-year-old infants in the back-to-back condition. Furthermore, we found that infants' gaze following could be negatively predicted by their expectation of the partner's response to the actor's head turn (i.e., they shift their gaze toward the partner immediately after they realize that the actor's head will turn). These findings suggested that the sensitivity to the difference in knowledge and attentional states in the second year of human life could be extended to third-party interactions, even without any direct involvement in the situation. Additionally, a spontaneous concern with the epistemic gap between self and other, as well as between others, develops by this age. These processes might be considered part of the fundamental basis for human communication..

7. Taro Murakami, Kazuhide Hashiya, Development of reference assignment in children: a direct comparison to
the performance of cognitive shift, Frontiers in Psychology, 10.3389/fpsyg.2014.00523, 5, 523, 2014.05, The referent of a deictic embedded in a particular utterance or sentence is often ambiguous. Reference assignment is a pragmatic process that enables the disambiguation of such a referent. Previous studies have demonstrated that receivers use social-pragmatic information during referent assignment; however, it is still unclear which aspects of cognitive development affect the development of referential processing in children. The present study directly assessed the relationship between performance on a reference assignment task (Murakami & Hashiya, 2014) and the dimensional change card sort task (DCCS) in three- and five-year-old children. The results indicated that the 3-year-old children who passed DCCS showed performance above chance level in the event which required an explicit (cognitive) shift, while the performance of the children who failed DCCS remained in the range of chance level; however, such a tendency was not observed in the 5-year-olds, possibly due to a ceiling effect. The results indicated that, though the development of skills that mediate cognitive shifting might adequately explain the explicit shift of attention in conversation, the pragmatic processes underlying the implicit shift, which requires reference assignment, might follow a different developmental course.
