This study reports on crawling variability and differences in variability between infants with typical development (TD) and those with developmental delays. This longitudinal study included 0-year-old infants with no apparent dysfunction. The crawling movement in the video was coded objectively with reference to previous research. The infants were…

Pretend play is important for children's development. However, recent research indicates that, as preschool children age and get more proficient at pretend play, they prefer real objects. We examined whether toddlers prefer real objects when they are younger as well as when they are older and more proficient in pretend play situations. Forty-three…

There is an absence of cross-cultural qualitative research exploring sociocultural factors affecting reading motivation. To address the gap, the present study adopted the Bronfenbrenner's bioecological model of human development to investigate factors impacting reading motivation across American and Japanese fourth grade students. Additionally, we…

This longitudinal study aimed to investigate infants' spontaneous object interactions during naturalistic longitudinal observations in a day care centre in Japan. Infants' and caregivers' interactions during free play time were videotaped. The main focus related to how infants' object interactions changed during locomotor development. Observations…

Previous cross-cultural research has described two different attention styles: a holistic style, characterized by context-sensitive processing, generally associated with interdependent cultural contexts, and an analytic style, a higher focus on salient objects, generally found in independent cultural contexts. Though a general assumption in the…

Child education and accompanying discourse in the seventeenth-century circles of Constantijn Huygens are thoroughly researched. But while children grow up, parents also learn and not only through their siblings. Some remarks about experiences that Huygens had outside the regular discourse on education can be made. Huygens' correspondence and his…

A wealth of developmental research suggests that preschoolers are capable of reporting, imitating, and performing sequential actions they engage in routinely. However, few studies have explored the developmental and cognitive mechanisms required for learning how to perform such routines. A previous computational model of routines argued that a…

This study explored child behaviours that enable mothers to perceive their child's minds. We administered the Mind Perception Questionnaire to 216 women with children aged between 0 and 24 months and 221 working women without children. Participants responded with mind perceptions for various entities, including for their children (a 0--2-year-old…

Studies on development and fairness judgments in resource allocations have mainly addressed the distribution of reward. However, the distribution of responsibility also requires exploration in the context of research on development and distributive justice. For an integrated understanding of reward and responsibility distributions, we briefly…

Some children form an attachment to a variety of inanimate objects, such as cloths or soft toys, referred to as attachment objects. This study examined the developmental change in children's behaviours toward their attachment objects to understand the role of such objects through an online survey of 700 parents with 0- to 9-year-old children, of…

This study investigated developmental changes in metacognitive strategies during elementary school years and examined the effects of intrinsic motivation on metacognitive strategies. A total of 113 Japanese elementary school children participated in a three-year longitudinal survey with eight times measurement occasions. Multilevel modeling…

The first years of life lay the foundations for a child's future development and learning. Many countries have increased their financial support for provision of early childhood education and care (ECEC) over the past years. More recently, the focus of debate has been shifting from expanding access to affordable ECEC to enhancing its quality. A…

It is unknown whether linguistic cues influence preschoolers' recognition of facial expression when the emotion of the face is incongruent with the linguistic cues and what type of linguistic cue is influential in the modulation of facial expression. In a priming task, we presented 5-year-old children three types of linguistic information…

Executive functions (EF) are an important predictor of later adaptive development. A number of environmental influences, such as parenting, have been suggested as important promoters of EF development. However, behavioural genetic research has demonstrated that many environmental influences could be affected by genetic influences. Therefore, it is…

This study investigated age differences in the utilization of visually contrastive information (i.e., differently colored identical objects) for temporary referential ambiguity resolution during spoken sentence comprehension. Five- and 6-year-old Japanese children and adults listened to sentences that contained a color adjective-noun combination…
