Background: The relationship between inadequate sleep and mood has been well-established in adults and is supported primarily by correlational data in younger populations. Given that adolescents often experience shortened sleep on school nights, we sought to better understand the effect of experimentally induced chronic sleep restriction on…

Background: Reviews have highlighted anxious youths' affective disturbances, specifically, elevated negative emotions and reliance on ineffective emotion regulation strategies. However, no study has examined anxious youth's emotional reactivity and regulation in real-world contexts. Methods: This study utilized an ecological momentary assessment…

Interactive engagement (IE) is a process that promotes students' conceptual understanding through activities, combined with immediate feedback from peers and/or instructors. The present study investigates the impact of IE on students' academic performance, using the comprehensive model of educational effectiveness. Engineering students (n?=?158),…

The present study evaluated the effectiveness of a parent training and emotion socialization program designed specifically for hyperactive preschoolers. Participants were 31 preschool-aged children whose parents were randomly assigned to a parent training (PT) or waitlist (WL) control group. PT parents took part in a 14-week parenting program that…

This mixed-method, longitudinal study investigated the benefits of project-based learning (PBL) on secondary-mathematics students' academic skill development and motivated strategies for learning (i.e., cognitive, social, and motivational). The focus of this study was academic skill development (algebra- and geometry-assessment scores) and other…

We examined the impact of a teacher-led intervention, implemented during regular classroom instruction and homework, on fourth-grade students' preference for self-regulated learning, finding main ideas in expository texts, and reading comprehension. In our quasi-experimental study with intact classrooms, (a) students (n = 266, 12 classrooms) who…

Fourth graders whose silent word reading and/or sentence reading rate was, on average, two-thirds standard deviation below their oral reading of real and pseudowords and reading comprehension accuracy were randomly assigned to treatment ("n" = 7) or wait-listed ("n" = 7) control groups. Following nine sessions combining…

This study examined the effects of Collaborative Strategic Reading (CSR) on informational text comprehension and metacognitive awareness of fifth grade students. This study tested the theories of metacognition and social cognition with a focus on self-regulation and self-efficacy. Participating students included a heterogeneous mix of regular…

This study explored the potential of classroom-based meditation practice as a tool to facilitate learning. Moreover, the impact of meditation on cognitive engagement, mindfulness and academic performance of undergraduate college students was investigated. Additionally, the relationships between mindfulness and cognitive engagement, and between…

The goal of this study is twofold: (1) to assess brain anatomical differences between children meeting diagnostic criteria for oppositional defiant disorder (ODD) and healthy controls, and (2) to investigate whether morphological brain characteristics associated with ODD differ in boys and girls. Eight-year-old participants (N = 38) were scanned…

In recent years, self-regulation has emerged as a foundational skill for academic success and well-being. Unfortunately, many children enter kindergarten without the self-regulation skills necessary to succeed. Children from high-risk backgrounds (e.g., low-income) are particularly vulnerable for difficulties in self-regulation development. Given…

We examined the effect of individualizing student instruction (ISI; N = 445 students, 46 classrooms) on first graders' self-regulation gains compared to a business-as-usual control group. Self-regulation, conceptualized as a constellation of executive skills, was positively associated with academic development. We hypothesized that the ISI…

This study explored the relationship between trajectories of affective self-regulation skills during secondary school and young adult substance use in a large multiethnic, urban sample (N = 995). During secondary school, participants completed a measure of cognitive and behavioral skills used to control negative, unpleasant emotions or perceived…

We investigated the psychometric properties of a new instrument, the Children's Worry Management Scale (CWMS). The CWMS has three subscales that specify methods of regulating worry: inhibition (the suppression of worry), dysregulation (exaggerated displays of worry), and coping (constructive ways of managing worry). Using a Caucasian, middle-class…

The aim of this study was to establish the nature of the relations between inhibitory control (IC) and false belief understanding (FBU). Twenty-eight children, participating in an experimental condition, were tested on a battery of FBU and IC tasks every four weeks for six phases of testing. A control group of 14 children completed the battery…
