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..|

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..

This study set two experimental conditions to separate the possibility of local correspondence based on the persisting strategy of reference assignment from that of more flexible reference skills. A total of 139 three-year-old and five-year-old children engaged in referencing names and colours in response to ambiguous implicit questions. The double-referent condition involved a reference assignment task, which alternated explicit questions and implicit questions. In the single-referent condition, implicit questions appeared at different positions within a series of interactions. The results demonstrated no difference between the conditions, indicating that the difficulty of disambiguation was not due to local correspondences such as “this”-referent mappings in a particular context. This suggests that the study's procedure appropriately probed inferential competence to enable retrospective disambiguation, thus providing a potential tool for assessing various aspects of pragmatic interpretation. Highlights: The main research question is whether the experience of "this"-referent mappings affects to interpret the subsequent ambiguous referent. A total of 139 three- and five-year-old children were engaged in the reference assignment task. The results demonstrated that the tendency of disambiguation was not due to local correspondence such as "this"-referent mappings in a particular context. The procedure used in the study appropriately reflected inferential competence that enables retrospective disambiguation..|

Research on links between working memory and referent assignment, PloS one, 10.1371/journal.pone.0187368, 12, 10, 2017.10, Understanding the referent of other’s utterance by referring the contextual information helps in smooth communication. Although this pragmatic referential process can be observed even in infants, its underlying mechanism and relative abilities remain unclear. This study aimed to comprehend the background of the referential process by investigating whether the phonological loop affected the referent assignment. A total of 76 children (43 girls) aged 3–5 years participated in a reference assignment task in which an experimenter asked them to answer explicit (e.g., “What color is this?”) and ambiguous (e.g., “What about this?”) questions about colorful objects. The phonological loop capacity was measured by using the forward digit span task in which children were required to repeat the numbers as an experimenter uttered them. The results showed that the scores of the forward digit span task positively predicted correct response to explicit questions and part of the ambiguous questions. That is, the phonological loop capacity did not have effects on referent assignment in response to ambiguous questions that were asked after a topic shift of the explicit questions and thus required a backward reference to the preceding explicit questions to detect the intent of the current ambiguous questions. These results suggest that although the phonological loop capacity could overtly enhance the storage of verbal information, it does not seem to directly contribute to the pragmatic referential process, which might require further social cognitive processes..

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..|

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.
