While there is considerable evidence that children's early ability to understand others' mental states, called "theory of mind," is shaped by family experiences, it remains unclear whether children's social interactions at school influence theory of mind (ToM) beyond early childhood. We tested whether the mean level…

Research on the multisensory control of locomotion has demonstrated that adults exhibit auditory-motor entrainment across an array of contexts. In such work adults will consciously modulate the cadence of their walking when instructed to match their footfalls to an auditory metronome equal to, slower than, or faster than, their natural walking…

We examine the long-standing claim that understanding relational correspondence is a general component of representational understanding. Two experiments with 175 preschool children located in Norwich, United Kingdom, examined the use of a scale model comparing performances on a "copy" task, measuring abstract spatial arrangement…

Understanding distinctions between morality and conventions is an important milestone in children's moral development. The current meta-analysis integrated decades of social domain theory research (Smetana, 2006; Turiel, 1983) on moral and conventional judgments from early to middle childhood. We examined 95 effect sizes from 18 studies (2,707…

Although the influence of intent understanding on children's moral development has been long studied, little research has examined the influence of belief understanding on that development. In two studies we presented children with morally relevant belief vignettes to examine the extent to which they incorporate both intent and belief information…

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…

Recent research has shown that a religious upbringing renders children receptive to ordinarily impossible outcomes, but the underlying mechanism for this effect remains unclear. Exposure to religious teachings might alter children's basic understanding of causality. Alternatively, religious exposure might only affect children's religious…

Past research has demonstrated that both consequentialist motives (such as deterrence) and deontological motives (such as "just deserts") underlie children's and adults' punitive behavior. But what motives do we ascribe to others who pursue punishment? The present work explores this question by assessing which punitive motives children…

The aim of this research was to develop a new observation-based measure for assessing caregivers' mind-mindedness in the preschool years and investigate whether this measure could explain the link between mothers' early appropriate mind-related comments and children's later mentalizing abilities. The new measure was developed using a sample of…

One developmental task faced by children is to identify, remember, and learn from epistemic and moral agents around them who are known to be good or virtuous. Here, in 2 studies, we examined U.S children's (N = 138; 55% female, 45% male; predominantly White, middle-class) memory processes for agents varying in moral and epistemic virtue. In Study…

False memories are well established episodic memory phenomena. Recent research in young adults has shown that semantically related associates can be falsely remembered as studied items in working memory (WM) tasks for lists of only a few items when a short 4-second interval was given between study and test. The present study reported two…

Why do infants learn some words earlier than others? Many theories of early word learning focus on explaining how infants map labels onto concrete objects. However, words that are more abstract than object nouns, such as "uh-oh," "hi," "more," "up," and "all-gone," are typically among the first to…

Learning from others allows young children to acquire vast amounts of information quickly, but doing so effectively also requires epistemic vigilance. Although preschool-age children have some capacity to engage in such processes, they often have trouble resisting information from misleading informants. The present research takes a "novel…

From his first attempts to explain attachment phenomena in the 1940s through his "Attachment and Loss" trilogy (Bowlby, 1969/1982, 1973, 1980), John Bowlby reformulated the theoretical underpinnings of attachment theory several times. He initially attempted to explain attachment phenomena in psychoanalytic terms. Then he invoked…

Children all over the world learn language, yet the contexts in which they do so vary substantially. This variation needs to be systematically quantified to build robust and generalizable theories of language acquisition. We compared communicative interactions between parents and their 2-year-old children (N = 99 families) during mealtime across…
