Early childhood is characterized by rapid increases in both motor skills and executive function skills. Rather than simply codeveloping, the development of motor and executive function skills may be linked causally. In this article, we introduce corticomuscular coherence as a paradigm for psychologists interested in testing mechanistic questions…

Knowing the temporal direction of causal relations is critical for producing desired outcomes and explaining events. Existing evidence suggests that children start to grasp that causes must precede their effects (the temporal priority principle) by age 3; however, whether younger children also understand this has, to our knowledge, not previously…

Across all cultures, parents have intuitive ideas ("ethnotheories") of what undesirable child characteristics are as well as how to explain them. Yet there have been relatively few cross-cultural comparisons of parents' ethnotheories about the nature and causes of child misbehavior. 108 mothers of 5-year-old children from the United…

Children's self-regulation has been studied from a cognitive-behavioral perspective. However, the vital learning process involves how students absorb, assimilate, and respond to surrounding factors; thus, self-regulation also should be examined from a sociocultural perspective to support children's autonomous rather than controlled…

This study examined children's emotion attributions and moral judgements to hypothetical procedural justice outcomes when the candidates were equal in merit but different in need. Children (7 to 11 years old, N = 88) were presented with four vignettes depicting resource-rich and resource-poor candidates losing educational materials and…

Children of teen mothers have worse academic, labor market, and behavioral outcomes in the United States, but it is not clear whether these poor outcomes are caused by having a young mother or driven by selection into teen motherhood. Understanding the reasoning behind poor child outcomes is important for designing effective policies to improve…

How does language shape mathematical development? In this article, we consider this question by reviewing findings from cross-sectional and longitudinal research. In this literature, we find that differences in the structures of languages and individual variations in language ability are associated with mathematical performance in both obvious and…

In two experiments, one hundred and sixty-two 6- to 8-year-olds were asked to reason counterfactually about events with different causal structures. All events involved overdetermined outcomes in which two different causal events led to the same outcome. In Experiment 1, children heard stories with either an ambiguous causal relation between…

Verbs are often uttered before the events they describe. By 2 years of age, toddlers can learn from such an encounter. Hearing a novel verb in transitive sentences (e.g. "The boy lorped the cat"), even with no visual referent present, they later map it to a causative meaning (e.g. "feed") (e.g. Yuan & Fisher, [Yuan, S.,…

The question of when moral identity first develops in childhood deserves more considered investigation. In this article, we examine the claim that moral identity first emerges in middle-childhood (8-12 years). An approach is taken here whereby a tendency to attribute moral shame under conditions entailing moral identity failure is considered as…

This review challenges the traditional interpretation of infants' and young children's responses to three types of potentially "fear-inducing" stimuli--snakes and spiders, heights, and strangers. The traditional account is that these stimuli are the objects of infants' earliest developing fears. We present evidence against the…

Exposure to nonionizing radiation used in wireless communication remains a contentious topic in the public mind--while the overwhelming scientific evidence to date suggests that microwave and radio frequencies used in modern communications are safe, public apprehension remains considerable. A recent article in "Child Development" has…

This study tested the prediction that, with age, children should rely less on familiarity and more on expertise in their selective social learning. Experiment 1 (N = 50) found that 5- to 6-year-olds copied the technique their mother used to extract a prize from a novel puzzle box, in preference to both a stranger and an established expert. This…

Remembering to carry out intended actions in the future, known as prospective memory (PM), is an important cognitive ability. In daily life, individuals remember to perform future tasks that might rely on effortful processes (monitoring) but also habitual tasks that might rely on more automatic processes. The development of PM across childhood in…

This paper presents data from a Forest School project aimed at impacting upon children and young people's emotional wellbeing. It uses a theory of change methodology to evaluate impact and explore the causal processes within the project. Mixed methods data are presented and analysed in relation to how different parts of the Forest School approach,…
