Self-produced locomotion is regarded as a setting event for other developmental transitions in infancy with important implications for socioemotional development and parent-child interaction. Using an age-held-constant design, this study examined changes in reported infant behaviour and maternal proactive/reactive control and compared them with…

Studies of children's knowledge of the Earth have led to very different conclusions: some appear to show that children construct their own, non-scientific "theories" (mental models) of the flat, hollow or dual Earth. Others indicate that many young children have some understanding of the spherical (scientific) Earth, and that their…

This study examined the prevalence and determinants of spanking of children at 3?years of age and the associations between spanking and externalizing behaviour and receptive verbal ability at age 5?years. Overall, we find maternal spanking rates of 55.2% and paternal rates of 43.2% at age 3?years. Mothers facing greater stress and those who…

Eighty 7-9 year olds (40 from each country) participated in interviews in which they were asked to make inferences about the stability, malleability, and causal origins of aggressive behaviour. Although a minority of participants…
