Children draw favorite peers close to them in pictures
Knowing a child’s affiliative feelings about a peer helps us understand child’s social behavior toward peers and can predict how a relationship between two children would continue. A picture-drawing task, in which a child draws himself or herself and a peer, is a potentially valid way to measure a child’s feelings of affiliation toward the peer. In this study, we established the validity of the picture-drawing task by testing two hypotheses: whet…
Impact of talker variability on language development in two-year-olds
This research investigated the impact of the number of talkers with whom children engage in daily conversation on their language development. Two surveys were conducted in 2020, targeting two-year-olds growing up in Japanese monolingual families. Caregivers reported the number of talkers in three age groups and children’s productive vocabulary via questionnaires. The results demonstrated significant effects of variability in talkers in fifth grad…
Comprehension of Null and Pronominal Object Sentences in Japanese-speaking Children
In successful communication, it is critical to have the ability to identify what a speaker is referring to from previously mentioned information. This ability requires the identification of the topic initially introduced by lexical forms and its continuity in discourse expressed by anaphora such as null and pronominal forms in the subsequent sentences. While Japanese-speaking children are frequently provided with pronominal and null forms, especi…
Letter visual similarity of Japanese hiragana and katakana based on reaction times
Abstrac t Letter similarity (i.e., perceptual distance) is a critical measure to better understand letter perception and literacy development. Despite its importance, however, measurements of letter similarity for non-alphabetic scripts are limited, and the shortage of letter similarity for non-alphabetic script interferes with the identification of the universality and the uniqueness of letter perception systems across different scripts. In the …
A robot is watching me
Since robots are becoming involved in children's lives, it is urgent to determine how children perceive robots. The present study assessed whether Japanese 5-year-olds care about their reputation when interacting with a social robot. Children were given stickers and asked to divide them between themselves and an absent recipient. Results revealed that children (N = 112, 55 boys, 57 girls) strategically shared more stickers when being watched by a…
Third-party punishment by preverbal infants
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…
How do Children Evaluate the Gossiper of Negative Gossip
In this study, we investigated how children evaluate gossipers. There are two conflicting ways in which children evaluate the gossiper of negative gossip about another person. One is that they perceive the gossiper of negative gossip as bad because saying something negative about another person can be seen as indirect aggression. The other is that they perceive the gossiper of negative gossip as good because such gossip is beneficial to regulate …
Children manage their reputation by caring about gossip
Individuals engage in reputation management by adjusting their behaviour in front of others. As gossip plays an important role in human society, individuals need to concern themselves with not only a present observer's evaluations but also non‐present people's impressions. In this study, we investigated whether 4‐ and 8‐year‐old children ( N = 144) would adjust their sharing behaviours when presented with the possibility of an observer's gossipin…
Ostension affects infant learning more than attention
Working Toward Cross-Cultural Adaptation
To facilitate preschoolers’ emotional development, it is useful to have a developmentally and culturally appropriate measure of emotion knowledge. The Affect Knowledge Test (AKT), a widely used measure of emotion knowledge, has been previously used with diverse cultural groups, including Japanese preschoolers, despite scarce reliability and validity information. Thus, the purpose of the present study was to conduct field tests of the Japanese-tra…
The Use of Pitch Accent in Word–Object Association by Monolingual Japanese Infants
This study investigated the lexical use of Japanese pitch accent in Japanese‐learning infants. A word–object association task revealed that 18‐month‐old infants succeeded in learning the associations between two nonsense objects paired with two nonsense words minimally distinguished by pitch pattern (Experiment 1). In contrast, 14‐month‐old infants failed (Experiment 2). Eighteen‐month‐old infants succeeded even for sounds that contained only the…
Sensitivity to register selection errors amongst 5- and 7-year-old children
We are expected to behave appropriately to suit social situations. One form of behavioral control is the selection of a linguistic register that is appropriate to the listener. Register selection errors can sometimes be interpreted as rude behavior and result in having a bad influence on the relationship with the listener and the evaluation by other people. Previous studies have demonstrated that children begin to show sensitivity to registers fr…
Early verb learning in 20-month-old Japanese-speaking children
The present study investigated whether children's representations of morphosyntactic information are abstract enough to guide early verb learning. Using an infant-controlled habituation paradigm with a switch design, Japanese-speaking children aged 1 ; 8 were habituated to two different events in which an object was engaging in an action. Each event was paired with a novel word embedded in a single intransitive verb sentence frame. The results in…
Social factors in the acquisition of a new word order
Present syntax acquisition tasks are not optimal for studying how children learn a new syntactic constraint and generalize it in sentence production. To address this issue, this study modified Akhtar’s production task where novel word orders were learned, so that it was more socially natural. Three- and four-year-old children were tested in this new task and the role of input factors was assessed. The new task was more effective at eliciting the …
