The current study addressed how the timing of interviews affected children's memories of unique and repeated events. Five- to six-year-olds (N = 125) participated in activities 1 or 4 times and were misinformed either 3 or 21 days after the only or last event. Although single-experience children were subsequently less accurate in the 21- versus…

To what extent do children with autism (AD) versus typically developing children (TD) rely on attentional and intentional cues to learn words? Four experiments compared 17 AD children (M age = 5.08 years) with 17 language- and 17 mental-age-matched TD children (M ages = 2.57 and 3.12 years, respectively) on nonverbal enactment and word-learning…

Given that girls show more interpersonal concern than boys, it was predicted that more mother-daughter than mother-son dyads would develop a relationship of mutual concerned responsiveness (CR). Two hundred and twenty-six Israeli children (7-8 years old) and 91 mother-child pairs provided narratives of mother-child interactions. At high levels of…

In a prospective study of developmental outcomes in relation to early-life otitis media, behavioral, cognitive, and language measures were administered to a large, diverse sample of children at 2, 3, 4, 6, and 9-11 years of age (N = 741). At 9-11 years of age, 9% of the children were categorized as having attention-deficit/hyperactivity disorder…

Using a genetic design of 840 60-month-old twins, this study investigated the genetic and environmental contributions to (a) individual differences in four components of cognitive school readiness, (b) the general ability underlying these four components, and (c) the predictive association between school readiness and school achievement. Results…

A sample of 341 5 1/2-year-old children participating in an ongoing longitudinal study was the focus of a study on the relation between cardiac vagal regulation and peer status. To assess cardiac vagal regulation, resting measures of respiratory sinus arrhythmia (RSA) and RSA change (suppression) to 3 cognitively and emotionally challenging tasks…

This study tests the firm distinction children are said to make between living and nonliving kinds. Three, 4-, and 5-year-old children and adults reasoned about whether items that varied on 3 dimensions (alive, face, behavior) had a range of properties (biological, psychological, perceptual, artifact, novel, proper names). Findings demonstrate…

Three- to 5-year olds heard two novel labels each applied to the same novel object. About half the children accepted both labels, thereby overriding mutual exclusivity. About half the children honored mutual exclusivity by accepting only one of the labels. (BC)

Forty-one children (3 to 7 years) were exposed to a staged event and later interviewed by 1 of 41 professional interviewers. All interviews were coded with a detailed, mutually exclusive, and exhaustive coding scheme capturing adult behaviors (leading questions vs. neutral) and child behaviors (acquiescence vs. denial) in a temporally organized…

Children more frequently specified possibilities correctly when uncertainty resided in the physical world (physical uncertainty) than in their own perspective of ignorance (epistemic uncertainty). In Experiment 1 (N=61), 4- to 6-year-olds marked both doors from which a block might emerge when the outcome was undetermined, but a single door when…

This study on sensitivity and attachment included 55 toddlers and their parents. Samples included children with autism spectrum disorder (ASD), mental retardation, language delay, and typical development. Children were diagnosed at 4 years of age. Two years before diagnosis, attachment was assessed with the Strange Situation procedure, and…

A 32-item test battery was administered to 154 male and female elementary school students to describe the static balance ability of 6- to 9-year-old children. Body position, visual use, and one-footed static base of support were found to affect subjects' balance performance. (Author/RH)

Easy and difficult tasks were presented to three year olds and their responses of shame and pride were observed. Subjects showed more shame when they failed easy tasks than difficult tasks, and more pride when they succeeded on difficult tasks than easy tasks. Girls showed more shame than boys. (BC)

In five investigations, three- and four-year-old children watched enactments of stories in which a character made statements that were either discrepant or consistent with a real situation. Children correctly judged the character's intentions in both the discrepant and the consistent stories. (BC)

In one of three studies, preschoolers judged that items that shared material properties, such as metal composition, would share dispositional properties, such as corrodibility in water, and that items of the same object type, such as baseball bats, would share functional properties, such as the ability to accelerate a baseball.
