Background: Parent-child interaction therapy (PCIT) is an evidence-based approach typically used for children aged 2-7 with externalizing disorders. Research suggests that PCIT is effective in treating a broad range of populations and problems. Several adaptations of PCIT have been developed for its use with children younger than the age of 2,…

A key factor that affects whether and at what age children can demonstrate an understanding of false belief and complement-clause constructions is the type of task used (whether it is implicit/indirect or explicit/direct). In the current study, we investigate, in an implicit/indirect way, whether children understand that a story character's belief…

Many studies examine how bilinguals and monolinguals differ in their executive function abilities at one time-point or cross-sectionally. Fewer examine how these groups of children may differ over time. Using nationally representative data obtained from the Early Childhood Longitudinal Study, Kindergarten Class of 2010-2011 (ECLS-K:2011), this…

This study investigates the influence of semantic maturation on early lexical development by examining the impact of contextual diversity--known to influence semantic development--on word promotion from receptive to productive vocabularies (i.e., comprehension-expression gap). Study 1 compares the vocabularies of 3685 American-English-speaking…

Maurice Sendak's picture book Where the "Wild Things Are" was investigated as a means of emotion recognition in preschool children. Sixty-six children and 60 adults participated in two tasks. The first was a book task, requiring identification of emotions in three target pictures, in three conditions. The visual condition presented the…

Although scholars have researched Chinese parents' perspectives on play pedagogy, few investigate the differences between parents of preschoolers and early primary schoolers, non-immigrant and immigrant parents. The present study employs the theoretical framework of parental ethnotheories to describe parental understanding and concerns about the…

Assessing children's working memory capacity (WMC) can be challenging for a variety of reasons, including the rapid increase in WMC across early childhood. Here, we developed and piloted an adapted WMC task, which involved minimal equipment, could be performed rapidly, and did not rely on verbal production ability (to facilitate the use of the…

How do young children decide which events can happen within fictional stories (extension) and learn new information from these stories (export)? In two studies, we investigate these two issues as well as the influence of story genre (realistic or fantastical) on these processes. Preschoolers (N = 192) heard either a realistic or fantastical story…

Shared intentionality theory posits that at age 3, children expand their conception of plural agency to include 3- or more-person groups. We sought to determine whether this conceptual shift is detectable in children's pronoun use. We report the results of a series of Bayesian hierarchical generative models fitted to 479 English-speaking…

Increased recognition of the need to study child development outside of research labs in naturalistic contexts has led to the formation of partnerships between researchers and museums. Researcher-museum partnerships provide researchers access to families and naturalistic contexts in museums to study learning and social development. Although…

Interactions between the amygdala and prefrontal cortex are fundamental to human emotion. Despite the central role of frontoamygdala communication in adult emotional learning and regulation, little is known about how top-down control emerges during human development. In the present cross-sectional pilot study, we experimentally manipulated…

This study aims to compare the effects of "questioning with minimal evaluation" (PE) and "prompt-evaluate-expand-repeat" (PEER) used in dialogic reading (DR) on children's language development. This study included 119 typically developing (TD) and 107 Chinese children with autism spectrum disorder (ASD) by using a pre- and…

Children develop and learn within dynamic contexts, yet the simplifying assumptions of common statistical methods often relegate such complexity to unexplained error. This chapter discusses ideas from the dynamic systems literature, which focuses on the interplay within and between components of complex systems, such as individuals and their…

This research takes a dyadic approach to study early word learning and focuses on toddlers' (N = 20, age: 17-23 months) "information seeking" and parents' "information providing" behaviors and the ways the two are coupled in real-time parent-child interactions. Using head-mounted eye tracking, this study provides the first…

Bilingual environments are more complex than monolingual environments. To adapt to this complexity, bilingual infants may navigate their environment in fundamentally different ways than monolingual infants. Drawing from visual, social, and linguistic processing, in this article, I present evidence to suggest that bilingual and monolingual learners…
