RESUMO
Forgiveness plays an important role in restoring and maintaining cooperative relationships. Previous studies have demonstrated that young children could forgive transgressors both as a third party and as a victim. However, the research on young children's understanding of forgiveness is scant. This study focused on the two main functions of forgiveness-the restoration of a damaged relationship between the victim and the transgressor and the positive emotional change in the victim toward the transgressor. In this study, 48 4-year-olds (25 girls), 50 5-year-olds (21 girls), and 50 6-year-olds (21 girls) in Japan heard stories in which a victim either did or did not forgive a transgressor. They answered questions about the relationship between the victim and the transgressor and the victim's feelings toward the transgressor. Regarding the restoration of a damaged relationship, 4- to 6-year-olds understood that the restoration could occur in the presence of forgiveness. Yet, 6-year-olds showed more distinctive belief than 4- and 5-year-olds that the damaged relationship remains unrestored without forgiveness from the victim. For emotional changes, 6-year-olds understood that the forgiving victim would experience positive emotional changes, whereas the unforgiving victim would not. However, 4- and 5-year-olds expected positive emotional changes even without forgiveness, although they anticipated greater changes after forgiveness. The results show that the understanding of the important functions of forgiveness is present at 4 years of age and matures by 6 years of age. Children may develop a sophisticated understanding of the functions of forgiveness later than the actual forgiving behavior.
RESUMO
Gossip allows children to effectively identify cooperative or trustworthy partners. However, the risk of being deceived must be faced because gossip may be false. One clue for determining gossip's veracity is the number of its sources since multiple informants spreading identical reputational information about others might imply that another's moral traits are viewed unanimously among members of a social group. We investigated whether 7-year-olds (N = 108) would trust gossip from multiple independent sources. In our study, they received multiple pieces of positive/negative reputational information about one agent and neutral information about another agent by gossip from either single or multiple informants. Then they allocated rewards to and chose rewards from the gossip targets. The 7-year-olds acted upon positive gossip from multiple informants and did not rely on positive gossip from a single informant. By contrast, they relied on negative gossip regardless of the number of informants. In either valence, however, they were more likely to allocate rewards based on gossip from multiple informants than a single informant. This result indicates they are sensitive to an objective index, specifically the number of sources, for judging the veracity of gossip.
RESUMO
Belief in gendered social power imbalance (i.e. males are more powerful than females) leads to undesirable gender disparities, but little is known about the developmental origins of this belief, especially in Eastern cultures. We investigated the development onset of this belief by focusing on 4-7-year-old Japanese children while considering another belief (females are nicer than males) for comparison. In the dyadic context tasks, children saw pairs of animated characters depicting powerful-powerless or kind-unkind postures and judged the characters' gender (boy or girl). Results suggested both 'nice = female' and 'powerful = female' gender stereotypes in children. In the collective context tasks, children were presented with stories in occupational contexts, including multiple unspecified people and verbal cues, describing more explicitly the powerful and nice traits of the protagonists. The results replicated the 'nice = female' gender stereotype. Moreover, early 'powerful = male' gender stereotypes were seen in 6-year-old boys but not among girls in general. These findings demonstrate that Japanese children's beliefs regarding gender differences in power vary depending on the context in which male-female interactions are presented. Additionally, the study reveals that signs of the 'powerful = male' social power gender stereotype emerge around the age of 6.
RESUMO
Throughout history, individuals believed to have extraordinary capabilities were generally highly ranked in their communities; this suggests a universal "extraordinary-dominant expectation" in human minds, which may play a key role in religious thought, even in modern societies. This study shows that 5-6-year-old children, who begin to understand real-world causalities regarding how the body and mind of human beings work, predict that individuals who exhibit extraordinary capabilities have higher social status in interactions with individuals who exhibit ordinary capabilities. In Experiment 1, we showed children two individuals achieving goals using either humanly possible or impossible methods, the latter involving simple forms of violation of intuitive psychology (knowing without seeing), physics (flying), or biology (fire breathing). The children clearly judged the latter as surprising and unusual. More importantly, the children predicted that individuals showing extraordinary capabilities will gain contested resources and play a dominant role in interactions with ordinary individuals, indicating a higher social status. Further investigations suggested that the children specifically linked extraordinary capacities to social status, as they did not attribute dominance to individuals who apply surprising/unusual but possible methods (Experiment 2), and that they did not indiscriminately attribute positive characteristics to extraordinary capabilities despite a strong extraordinary-dominant expectation being replicated (Experiment 3). These findings demonstrate that extraordinary-dominant expectations can be observed in childhood across different intuitive knowledge domains, helping understand the cognitive mechanisms of religious thought and the cognitive foundations of hierarchical social systems.

Japan has a large gender gap; thus, this study examined whether Japanese 4- to 7-year-old children exhibit a "brilliance = males" stereotype and whether parental attitudes toward gender roles were related to children's stereotypes. We also explored whether the children exhibited such stereotypes in response to various stimuli. We showed children photos (Study 1) and stick figures (Study 2) of men, women, boys, and girls, asking them to attribute traits (smart or nice) to each. Study 1 revealed overwhelming in-group positivity in girls, whereas the results for boys were rather mixed. In Study 2, girls generally attributed nice to their own gender compared to boys. However, "brilliance = males" stereotypical responses were observed from 7 years of age, when boys began to be more likely to attribute smartness to their own gender compared to girls. The new data in Study 3 replicated results of Study 1 and parts of the results of Study 2. Moreover, merging the Study 3 data with that of Studies 1 and 2 confirmed their findings. Furthermore, it replicated the "brilliance = males" stereotype among 7-year-olds in the stick figure task. Parental attitudes toward gender roles were unrelated to children's gender stereotypes. The results indicated that Japanese children may acquire "brilliance = males" stereotypes later than American children (6-years-old). Furthermore, the results were clearer when children were presented with stick figure stimuli.

Third-party punishment of antisocial others is unique to humans and seems to be universal across cultures. However, its emergence in ontogeny remains unknown. We developed a participatory cognitive paradigm using gaze-contingency techniques, in which infants can use their gaze to affect agents displayed on a monitor. In this paradigm, fixation on an agent triggers the event of a stone crushing the agent. Throughout five experiments (total N = 120), we show that eight-month-old infants punished antisocial others. Specifically, infants increased their selective looks at the aggressor after watching aggressive interactions. Additionally, three control experiments excluded alternative interpretations of their selective gaze, suggesting that punishment-related decision-making influenced looking behaviour. These findings indicate that a disposition for third-party punishment of antisocial others emerges in early infancy and emphasize the importance of third-party punishment for human cooperation. This behavioural tendency may be a human trait acquired over the course of evolution.

OBJECTIVE: Social scientists have suggested two typical ways of acquiring social power: dominance approach (gaining social power by applying violence, coercion, threat, and punishment) and prestige approach (gaining admiration and liking by demonstrating competence and sharing experience and knowledge). However, little is known about how people recognize and evaluate the differentiated process of the approaches, and even less about the early development of these processes. In the current study, 5-6-year old children heard stories about pairs comprising a dominance-based and a prestige-based powerholder, chose one of the powerholders as their friend and leader, and predicted which powerholder will gain the contested resources. RESULTS: Compared to a dominance-based powerholder, children were more likely to choose a prestige-based powerholder as a friend and leader in different situations. Moreover, children predicted that prestige-based powerholders, and not dominance-based powerholders, would gain contested resources. These findings suggest that since childhood, human beings tend to be biased to not only judge prestige-based aspects as socially preferable, but also endorse the prestige-based powerholders' priority to possess valuable resources, which subsequently strengthens their high social status. These early childhood preferences can be instrumental in providing more harmonious environments for children in educational and daily contexts.

Understanding how we see the world is different from how other people see it is a crucial part of social cognition and is known as visual perspective-taking. Although previous studies have demonstrated that 14-month-old infants have the capacity to compute the visual perspectives of others, it remains unknown whether infants under 12 months also have this ability. In this study, we modified a conventional gaze-following experimental setting in which one toy was placed in front of a model and was hidden by a barrier (Blocked Line of Sight Condition), and another toy was placed without a barrier (Clear Line of Sight Condition). We examined the visual perspective-taking abilities of 48 infants aged 7 and 12 months by measuring the infants' gaze shift towards the gaze-cued toy object with and without a barrier. The results demonstrated that 12-month-old infants could correctly follow a model's gaze if the model's line of sight was clear. In contrast, 7-month-old infants showed no evidence of such capacity. Our findings indicate that 12-month-old infants seem to have the capacity to compute the visual perspective of others.

There is growing evidence that preterm children are at an increased risk of poor executive functioning, which underlies behavioural and attention problems. Previous studies have suggested that early cognitive flexibility is a possible predictor of later executive function; however, how it develops in infancy and relates to the later neurobehavioural outcomes is still unclear in the preterm population. Here, we conducted a longitudinal study to investigate oculomotor response shifting in 27 preterm and 25 term infants at 12 months and its relationship with general cognitive development and effortful control, which is a temperamental aspect closely associated with executive function, at 18 months. We found that moderate to late preterm and term infants significantly inhibited previously rewarded look responses, while very preterm infants did not show significant inhibition of perseverative looking at 12 months. Moreover, lower inhibition of perseverative looking was significantly associated with lower general cognitive development and attentional shifting at 18 months. These findings suggest that the early atypical patterns of oculomotor response shifting may be a behavioural marker for predicting a higher risk of negative neurobehavioural outcomes, including attention-related problems in preterm children.

'Motionese' can be defined as an exaggerated and repetitive action. It induces preference and learning in infants. However, which action component of motionese promotes infants' preference and learning remains largely unknown. In this study, we focused on inefficiency and toward-ness of action. Our study demonstrates that observing an inefficient holding out action can induce a visual preference in 4-month-old infants and learning in 10-month-old infants through eight experiments (N = 192). We found that when infants observe inefficient holding out action, the action attracts their attention and facilitates learning about the identity of the toy object accompanying it, especially when people direct inefficient actions towards them. Our findings indicate that both action efficiency and toward-ness may be key factors in infant learning.

Children can identify who is benevolent or malevolent not only through first-hand experiences and observations but also from the testimony of others. In this study, we investigated whether 5- and 7-year-olds (N = 128) would form their attitudes toward others after hearing testimony about that person's past moral behavior and whether the valence of testimony would differently influence the children. In the positive condition, half of the participants gained information about three puppets: puppet A's prosocial behavior by their own first-hand observation, testimony about puppet B's past prosocial behavior, and testimony about puppet C's past neutral behavior. In the negative condition, the other half also learned information about the three puppets: puppet A's antisocial behavior by their own first-hand observation, testimony about puppet B's past antisocial behavior, and testimony about puppet C's past neutral behavior. Then they engaged in tasks that measured their behavioral attitudes toward the puppets and evaluated the goodness of each puppet to assess their attitudes at a cognitive level. Our results concluded that the children form their behavioral attitudes toward others based on testimony starting at the age of 7, and attitude formation at the cognitive level based on testimony is seen at age 5. Negative testimony, rather than positive testimony, influences the children's attitudes toward others. In addition, the 7-year-olds' use of testimony differs depending whether they are the allocators or the receivers of rewards. Our findings deepen understanding of how children rely on the verbal information around themselves when they navigate interactions with others.

A recent controversy in infants' social learning has revolved around whether ostensive cues have an effect beyond simply grabbing infants' attention: natural pedagogy theory vs. attention modulation theory. However, since previous research only focused on gaze-following behaviors, it has failed to determine whether attention-grabbing versus ostensive cues might affect infants' learning at different levels. To explore this possibility, we conducted a critical test with 9-month-old infants (N=140) in which gaze-following behavior was discriminated from referential learning about a target object (object processing and object preference). Here we report that although both attentional cues (shivering, a beep, and mouth-moving beep) and ostensive cues (infant-directed speech) affected infants' gaze-following, only ostensive cues facilitated their referential object learning. These findings provide new evidence that ostensive cues play a distinct role in infant learning, supporting natural pedagogy theory.

Vocal imitation plays a fundamental role in human language acquisition from infancy. Little is known, however, about how infants imitate other's sounds. We focused on three factors: (a) whether infants receive information from upright faces, (b) the infant's observation of the speaker's mouth and (c) the speaker directing their gaze towards the infant. We recorded the eye movements of 6-month-olds who participated in experiments watching videos of a speaker producing vowel sounds. We found that an infants' tendency to vocally imitate such videos increased as a function of (a) seeing upright rather than inverted faces, (b) their increased looking towards the speaker's mouth and (c) whether the speaker directed their gaze towards, rather than away from infants. These latter findings are consistent with theories of motor resonance and natural pedagogy respectively. New light has been shed on the cues and underlying mechanisms linking infant speech perception and production.

The theory of natural pedagogy has proposed that infants can use ostensive signals, including eye contact, infant-directed speech, and contingency to learn from others. However, the role of bodily gestures, such as hand-waving, in social learning has been largely ignored. To address this gap in the literature, this study sought to determine whether 4-month-old infants exhibited a preference for horizontal or vertical (control) hand-waving gestures. We also examined whether horizontal hand-waving gestures followed by pointing facilitated the process of object learning in 9-month-old infants. Results showed that 4-month-old infants preferred horizontal hand-waving gestures to vertical hand-waving gestures, even when featural and contextual information were removed. Furthermore, horizontal hand-waving gestures induced identity encoding for cued objects, whereas vertical gestures did not. These findings highlight the role of communicative intent embedded in bodily movements and indicate that hand-waving can serve as a new type of ostensive signal.

Interaction between caregivers and infants is multimodal in nature. To react interactively and smoothly to such multimodal signals, infants must integrate all these signals. However, few empirical infant studies have investigated how multimodal social interaction with physical contact facilitates multimodal integration, especially regarding audioâ¯-â¯tactile (A-T) information. By using electroencephalogram (EEG) and event-related potentials (ERPs), the present study investigated how neural processing involved in A-T integration is modulated by tactile interaction. Seven- to 8-months-old infants heard one pseudoword both whilst being tickled (multimodal 'A-T' condition), and not being tickled (unimodal 'A' condition). Thereafter, their EEG was measured during the perception of the same words. Compared to the A condition, the A-T condition resulted in enhanced ERPs and higher beta-band activity within the left temporal regions, indicating neural processing of A-T integration. Additionally, theta-band activity within the middle frontal region was enhanced, which may reflect enhanced attention to social information. Furthermore, differential ERPs correlated with the degree of engagement in the tickling interaction. We provide neural evidence that the integration of A-T information in infants' brains is facilitated through tactile interaction with others. Such plastic changes in neural processing may promote harmonious social interaction and effective learning in infancy.

Gaze-following behaviors play an important role in language development. However, the way in which gaze-following contributes to language development remains unclear. By focusing on two abilities, namely following the gaze direction of others and processing a cued object, the present study investigated how these two influences work together to promote language development in a longitudinal approach on infants from 9 to 18months of age. The results demonstrated that infants who spent more time following the gaze direction toward an object were more efficient in processing the cued object at 9months and had larger vocabularies by 18months. Mediation analyses showed that the relationship between early gaze-following behavior and subsequent vocabulary size was explained by object-processing ability. Importantly, mere extended fixations on a target object without the initiation of another's gaze shift were not related to enhanced object-processing. Our findings suggest that following another's gaze shift toward the object has an impact on object-processing that could contribute to vocabulary development, elucidating a critical step in the path from early gaze-following ability to later language development.

Previous studies have mainly examined how maternal behaviors influence infants during holding. However it is unclear how infants influence maternal holding. This current study investigated how infants' emotional states influence maternal holding behaviors, and whether maternal holding behaviors are also influenced by the mothers' parenting stress. We manipulated infants' emotional states and videotaped mothers' holding behaviors. The mothers also completed a questionnaire about their parental stress. Results showed that mothers varied their holding behaviors depending on their infants' emotional states. When infants were comfortable, mothers rocked them horizontally and quietly. When infants were uncomfortable, mothers rocked them vertically at a high frequency. Furthermore, some types of parenting stress were related to several types of maternal behaviors in the context of holding. These findings suggest that maternal holding behaviors are influenced by both the infants' emotional states and the mothers' parenting stress.

It has been shown that there is a significant relationship between children's mentalizing skills and creation of an imaginary companion (IC). Theorists have proposed that interaction with an IC may improve mentalizing skills, but it is also possible that children's mentalizing skills affect their creation of an IC. In this longitudinal study, we examined whether goal attribution in infants younger than 1 years old (Time 1) predicted their creation of ICs at 48 months old (Time 2). At Time 1, infants' goal attribution was measured in an action prediction experiment, where infants anticipated three types of action goals: (1) another person's goal-directed action (GH condition); (2) another person's non-goal-directed (BH condition); and (3) a mechanical claw's goal-directed action (MC condition). At Time 2, parents completed questionnaires assessing whether their children had ICs. The path analyses using Bayesian estimation revealed that infants' anticipation in the MC condition, but not in the GH and BH conditions, predicted their later IC status. These results indicate that infants' goal attributions to non-human agents may be a strong predictor of their later IC creation. Early mentalizing skills toward non-human objects may provide children with a basis for their engagement in imaginative play.
RESUMO
Animated pedagogical agents are lifelike virtual characters designed to augment learning. A review of developmental psychology literature led to the hypothesis that the temporal contingency of such agents would promote human learning. We developed a Pedagogical Agent with Gaze Interaction (PAGI), an experimental animated pedagogical agent that engages in gaze interaction with students. In this study, university students learned words of a foreign language, with temporally contingent PAGI (live group) or recorded version of PAGI (recorded group), which played pre-recorded sequences from live sessions. The result revealed that students in the live group scored considerably better than those in the recorded group. The finding indicates that incorporating temporal contingency of gaze interaction from a pedagogical agent has positive effect on learning.
RESUMO
When interacting with infants, human adults modify their behaviours in an exaggerated manner. Previous studies have demonstrated that infant-directed modification affects the infant's behaviour. However, little is known about how infant-directed modification is elicited during infant-parent interaction. We investigated whether and how the infant's behaviour affects the mother's action during an interaction. We recorded three-dimensional information of cup movements while mothers demonstrated a cup-nesting task during interaction with their infants aged 11 to 13 months. Analyses revealed that spatial characteristics of the mother's task demonstration clearly changed depending on the infant's object manipulation. In particular, the variance in the distance that the cup was moved decreased after the infant's cup nesting and increased after the infant's task-irrelevant manipulation (e.g. cup banging). This pattern was not observed for mothers with 6- to 8-month-olds, who do not have the fine motor skill to perform the action. These results indicate that the infant's action skill dynamically affects the infant-directed action and suggest that the mother is sensitive to the infant's potential to learn a novel action.
