Delay of gratification tasks have an impressive predictive value for various outcomes and are designed to measure self-regulation. Since many behavioural and psychological conditions in children are related to limitations in self-regulation, the extent to which delay tasks can be used as a screening for the detection of psychopathology is…

Previous research on children's knowledge about the mind has primarily focused on their comprehension of false beliefs, leaving the conceptualization of thoughts and thinking less explored. To address this gap, we developed a new assessment tool, the interview about the mind (IaM), to assess children's understanding of the mind. Two studies…

This study explores the cognitive development of children born to adolescent mothers within South Africa compared to existing reference data, and explores development by child age bands to examine relative levels of development. Cross-sectional analyses present data from 954 adolescents (10-19 years) and their first-born children (0-68 months).…

It is well established that children lie in different social contexts for various purposes from the age of 2 years. Surprisingly, little is known about whether very young children will spontaneously lie for personal gain, how self-benefiting lies emerge, and what cognitive factors affect the emergence of self-benefiting lies. To bridge this gap in…

Many studies have found that a majority of boys and girls prefer to play with toys that are typed to their own gender but there is still uncertainty about the age at which such sex differences first appear, and under what conditions. Applying a standardized research protocol and using a selection of gender-typed toys, we observed the toy…

The purpose of this study was to investigate the contributions of general cognitive skills (working memory, inhibition, and reasoning) and metalinguistic awareness to young children's character reading. One hundred eighty-nine Chinese children, aged from 60 to 78 months, were administered with measures of character recognition, language,…

The present study investigated children's internal state language during play with their sibling and friend across early and middle childhood. Specifically, the category type of internal state language (e.g., cognitions and goals), referent (e.g., own and other), and associations with children's birth order were examined. A total of 65 (T1: Time…

The objective of this study was to examine the role of the stimulus material for the prediction of later IQ by early learning measures in the Visual Expectation Paradigm (VExP). The VExP was assessed at 9?months using two types of stimuli, Greebles and human faces. Greebles were assumed to be associated with a higher load on working memory in…

Previous research indicates that children hold negative beliefs about peers with foreign accents, physical disabilities, and people who are obese. The current study examined skills associated with individual differences in children's social judgements about these typically stereotyped groups. Theory of mind, memory, and cognitive inhibition were…

The ability to connect numbers and magnitudes is an important prerequisite for math learning, here referred to as number-magnitude skills. It has been proposed that working memory plays an important role in constructing these connections. The aim of the current study was to examine if working memory accounts for constructing these connections by…

The influence of a model's age on young children's behaviour has been a subject of considerable debate among developmental theorists. Despite the recent surge of interest, controversy remains about the nature of peer influence in early life. This article reviews studies that investigated the influence of a model's age on young…

This research examined children's performance on second-order false belief tasks as a function of the content area for the belief and the method of assessing understanding. A total of 70 kindergarten and first-grade children responded to four second-order stories. On two stories, the task was to judge a belief about a belief, and on two, the…

Young children are frequently exposed to sounds such as speech and music in noisy listening conditions, which have the potential to disrupt their learning. Missing input that is masked by louder sounds can, under the right conditions, be "filled in" by the perceptual system using a process known as perceptual restoration. This experiment…

Children's ability to distinguish between enjoyment and non-enjoyment smiles was investigated by presenting participants with short video excerpts of smiles. Enjoyment smiles differed from non-enjoyment smiles by greater symmetry and by appearance changes produced in the eye region by the Cheek Raiser action. The results indicate that 6- and…

Recent research has demonstrated that social responsiveness (comprised of social awareness, social information processing, reciprocal social communication, social motivation, and repetitive/restricted interests) is continuously distributed within the general population. In the present study, we consider temperament as a co-occurring source of…
