Efforts to identify biological correlates of internalizing symptoms in childhood have involved examinations of HPA-axis functioning, namely Cortisol Awakening Response (CAR). However, research has not assessed the relationship between CAR and internalizing problems among children younger than 8 years. Findings with older samples have been somewhat…

A growing body of theoretical and empirical work has been attempting to answer the questions of how and how much of the effects of children's early experience may depend on their inner characteristics. Theory and evidence suggest that some children, notably those with difficult temperaments, are more susceptible to both negative and positive…

Holistic integrated early childhood policies foster child well-being in the first 3 years of life. The normative framing of Early Childhood Care and Education (ECCE) entrenches segmentation and creates artificial divides between education and health. This segmentation persists yet development processes for children are intertwined and mutually…

Now in its Third Edition, "Young Investigators" provides an introduction to the project approach with step-by-step guidance for conducting meaningful investigations with young children. The authors have expanded their bestseller to include two new chapters--"How Projects Can Connect Children with Nature" and "Project…

This resource was prepared in response to a request for information from a Race to the Top-Early Learning Challenge (RTT-ELC) State about which RTT-ELC States are using the Pyramid Model for Supporting Social Emotional Competence in Infants and Young Children. The State also requested information about other projects States have designed to…

Two studies examined young children's early understanding and evaluation of truth telling and lying and the role that factuality plays in their judgments. Study 1 (one hundred four 2- to 5-year-olds) found that even the youngest children reliably accepted true statements and rejected false statements and that older children's ability to…

Purpose: Vocabulary assessment holds promise as a way to identify young bilingual children at risk for language delay. This study compares 2 measures of vocabulary in a group of young Spanish-English bilingual children to a single-language measure used with monolingual children. Method: Total vocabulary and conceptual vocabulary were used to…

Cross-classified items pose an interesting challenge to children's induction as these items belong to many different categories, each of which may serve as a basis for a different type of inference. Inductive selectivity is the ability to appropriately make different types of inferences about a single cross-classifiable item based on its different…

The present study examined the relation between language and social ability in a sample of 268 preschoolers aged 18-35 months. Expressive language was assessed with the Italian adaptation of the Language Development Survey (LDS), and Social Competence was assessed with the Questionnaire on Peer Interactions in the Kindergarten (QPI). Results…

Behavioral inhibition is a temperament assessed in the toddler period via children's responses to novel contexts, objects, and unfamiliar adults. Social reticence is observed as onlooking, unoccupied behavior in the presence of unfamiliar peers and is linked to earlier behavioral inhibition. In the current study, we assessed behavioral inhibition…

The goal of the current study was to develop and pilot the utility of two simple internal response bias metrics, over-reporting and under-reporting, in terms of additive clinical value within common screening practices for early detection of autism spectrum disorder risk. Participants were caregivers and children under 36 months of age (n = 145)…

This study evaluated the predictive validity of the Autism Detection in Early Childhood (ADEC; Young, Autism detection in early childhood: ADEC. Australian Council of Educational Research, Camberwell, VIC 2007) and a well-established screening tool, the Childhood Autism Rating Scale (CARS; Schopler et al. The childhood autism rating scale (CARS).…

Individual differences in infant attention are theorized to reflect the speed of information processing and are related to later cognitive abilities (i.e., memory, language, and intelligence). This study provides the first systematic longitudinal analysis of infant attention and early childhood executive function (EF; e.g., working memory,…

The first distribution of Chinese infant-mother (n = 61) attachment classifications categorised by trained and reliability-tested coders is reported with statistical comparisons to US norms and previous Chinese distributions. Three-way distribution was 15% insecure-avoidant, 62% secure, 13% insecure-resistant, and 4-way distribution was 13%…

Southern Peruvian Quechua is an indigenous language spoken primarily in rural communities in the Peruvian Andes. The language includes a syntactic construction, "-paq", that expresses purpose or function, thus providing an opportunity to trace how parents and children with little formal education express teleological concepts. The…
