Evaluating evidence and restructuring beliefs based on anomalous evidence are fundamental aspects of scientific reasoning. These skills can be challenging for both children and adults, especially in domains where they possess inaccurate prior beliefs that can interfere with the acquisition of correct scientific information (e.g., heavier objects…

Children show less positivity toward gender-nonconforming (GN) than gender-conforming (GC) peers. Yet, little is known about children's reasoning about peers of varying gender expressions, including age-, gender-, and culture-related influences. We investigated how children aged 4- to 5- and 8- to 9-years-old in Hong Kong and Canada (N = 678)…

In pursuing goals, people seek favorable odds. We investigated whether young children use this fact to infer goals from people's actions across two experiments on Canadian 3- to 7-year-old children (N = 316; 167 girls, 149 boys). Participants' demographic information was not formally collected, but the region is predominantly middle-class and…

The goals of this study were to investigate (a) the dyadic relations of mothers' and children's perceptions of children's anxiety symptoms across development, (b) whether maternal perceptions of children's anxiety serve as a mediator of the association between maternal anxiety and child anxiety, and (c) whether sensitive/structured parenting…

Developing attention skills allow children to parse their complex world by orienting to a subset of especially salient or meaningful inputs. Infants and children are biased to orient to faces and have difficulty ignoring faces when they appear as distractors. Although these past findings suggest that faces are more salient than nonsocial stimuli,…

Observational studies have shown that caregiver sensitivity predicts child language skills. These studies, however, have entirely relied on between-family designs (single parent-child dyad per family), which cannot rule out the contribution of shared family confounds (e.g., genetics, books in home). The current study investigates whether observed…

Children have a robust social preference for people similar to them, like those who share their language, accent, and race. In the present research, we show that this preference can diminish when children consider who they want to learn about. Across three experiments, 4- to 6-year-olds (total N = 160; 74 female, 86 male, from the Waterloo region…

The risk potentiation model of cognitive control posits that inhibitory control heightens children's risk for problematic outcomes in the context of shyness because it limits shy children's ability to engage flexibly with their environment. Although there is empirical support for the risk potentiation model, most studies have been restricted to…

The present study investigated whether distinct developmental patterns of externalizing behaviors (EBs: hyperactivity-impulsivity, noncompliance, physical aggression) based on parent reports were repeatedly and differentially associated with separate dimensions of internalizing problems such as general anxiety, separation anxiety, and depressive…

This study examined the course and correlates of the happy victimizer tendency--the expectation that harming others to achieve a goal will result in positive emotional outcomes for the transgressor--from 4 to 6 years of age in a community sample of Canadian children (N = 150; 50% female; Time 1 M[subscript age] = 4.53 years, SD = 0.30; 33%…

Why do some children feel happy about violating ethical norms whereas others feel guilty? This study examined whether children's attention to two types of competing cues during hypothetical transgressions related to their subsequent emotions. Eye tracking was used to test whether attending to other-oriented cues (i.e., a victim's face) versus…

Given the value placed on honesty and the negative consequences of lying, encouraging children's truth-telling is important. The present investigation assessed honesty promotion techniques for encouraging 3-8-year-old Canadian children's (Study 1: n = 301, 54% female; Study 2: n = 229, 50% female from predominantly White middle-class samples)…

Young children often deny that improbable events are possible. We examined whether children aged 5-7 (N = 300) might have more success in recognizing that these events are possible if they considered whether the events could happen in a distant country. Children heard about improbable and impossible events (Experiments 1A, 1B, and 2) and about…

Past meta-analyses show that both child-mother and child-father attachment insecurity are independently and jointly associated with more externalizing behaviors in children. Little is known, however, on the ways that different types of insecure attachment independently and jointly predict the development of externalizing behaviors over time.…

HIV-exposed uninfected (HEU) children during the preschool and early school ages may be at-risk for neurodevelopmental challenges due to in utero and perinatal exposure to HIV and/or antiretroviral (ARV) medications. HEU children and HIV-unexposed uninfected (HUU) children from the community were recruited and tested at 3 to 4 and 5 to 6 years of…
