Performance measures, including standardized test scores or cognitive tasks, are commonly conceptualized as stable measures, yet are often unreliable indices of skill. We examine two contextual factors, performance pressure and feedback, that may influence the extent to which individuals demonstrate their cognitive capacity by manipulating…

The present study examines the link between children's number of older siblings and their cognitive development, as measured by executive function (EFs) skills and verbal skills (VIQ) in a sample of 1,302 4-year-old children (54% boys) living in rural Pakistan. Specifically, we investigate whether the links between the number of older siblings and…

A cluster randomized design was used to investigate effects of the Story Friends vocabulary curriculum on learning of 84 preschoolers in 24 classrooms who were at risk for language difficulties. Children in the treatment condition received explicit vocabulary instruction of 36 words during small-group storybook listening centers with extended…

Much recent research has focused on the relation between spatial skills and mathematical skills, which has resulted in widely reported links between these two skill sets. However, the magnitude of this relation is unclear. Furthermore, it is of interest whether this relation differs in size based on key demographic variables, such as gender and…

When confronted with an emotion prototype (e.g., loss), individuals may experience not only target emotions (e.g., sadness), but also nontarget emotions (emotions that are atypical or incongruent with an emotion prototype; e.g., gratitude in response to loss). What are the cognitive correlates of nontarget emotions? Drawing from models of emotion…

Previous studies have often compared and contrasted differences among media presentations, including traditional storybooks and videos and their potential for incidental word learning among preschoolers. Studies have shown that children learn words from a variety of media, and that repetition is an important source for incidental learning. Yet, to…

Mathematical and spatial reasoning abilities during childhood predict later success in male-dominated science, technology, engineering, and math (STEM) disciplines, yet relatively little is known about the affective correlates of children's math and spatial performance or gender differences therein. In the present research, we assessed math and…

This study centered on Dual Language Learners (DLLs) with specific reading comprehension deficits (S-RCD), that is, with poor reading comprehension despite solid word identification skills. The participants were 209 students in Grades 2-4, including both DLLs and English Monolinguals (EMs) with and without S-RCD. Mean comparisons indicated that…

Coviewing is a commonly recommended practice, but little is known about how coviewing impacts children's educational media viewing experience. We investigated how coviewing impacts attention and comprehension of educational media, as well as the role of baseline vocabulary in understanding these associations. Eighty-three preschoolers viewed two…

Experiences of contingent responsivity during shared book reading predict better learning outcomes. However, it is unclear whether contingent responsivity from a digital book could provide similar support for children. The effects on story recall and engagement interacting with a digital book that responded contingently on children's vocalizations…

The writing skills of autistic university students have received very little empirical attention. Previous research has suggested that autistic people may struggle with writing, in part, due to challenges with Theory of Mind. However, other research indicates that Theory of Mind difficulties are far from universal in autism, varying across…

Linguistic alignment--the contingent reuse of our interlocutors' language at all levels of linguistic structure--pervades human dialogue. Here, we design unique measures to capture the degree of linguistic alignment between interlocutors' linguistic representations at three levels of structure: lexical, syntactic, and semantic. We track these…

Classroom organization is an important facet of prekindergarten quality but is typically measured at a "global level" and as a "single construct." Little is known about how experiences of different facets of classroom organization--namely, exposure to teacher organizational strategies--vary across "individual…

Purpose: Many children begin school with limited vocabularies, placing them at a high risk of academic difficulties. The goal of this study was to examine the effects of a vocabulary intervention program, "Story Friends," designed to improve vocabulary knowledge of at-risk preschool children. Method: Twenty-four early-childhood…

The development of beginning decoding and encoding skills is influenced by linguistic skills as well as executive functions (EFs). These higher-level cognitive processes include working memory, inhibition, and cognitive flexibility, and individual differences in these EFs have been shown to contribute to early academic learning. The present study…
