Preprint
Externalizing behaviours in childhood often predict impulse control disorders in adulthood; however, the underlying biobehavioural risk factors are incompletely understood. In animals, the propensity to sign-track, or the degree to which incentive motivational value is attributed to reward cues, is associated with externalizing-type behaviours and...
Article
Objective This study sought to determine whether gastric symptoms are associated with later eating disorder (ED) symptoms during early adolescence, and whether this relationship is moderated by parental warmth/acceptance and/or the child's sex. Method Longitudinal data from the Adolescent Brain Cognitive DevelopmentSM Study were utilized. Particip...

This study used a machine learning framework in conjunction with a large battery of measures from 9,718 school‐age children (ages 9–11) from the Adolescent Brain Cognitive DevelopmentSM (ABCD) Study to identify factors associated with fluid cognitive functioning (FCF), or the capacity to learn, solve problems, and adapt to novel situations. The ide...

Neighborhood characteristics can have profound impacts on resident mental health, but the wide variability in methodologies used across studies makes it difficult to reach a consensus as to the implications of these impacts. The aim of this study was to simplify the assessment of neighborhood influence on mental health. We used a factor analysis ap...

Community processes to address fractured social relationships and well‐being remain the least examined dimensions in studies of legacies of civil wars. This article addresses these limitations by analyzing how the wartime and postwar generations have negotiated the legacies of the civil war (1976–1992) in a farming economy region in Mozambique. Bas...
Preprint
PurposeFluid cognitive functioning (FCF), or the capacity to learn, solve problems, and adapt to novel situations, is instrumental for academic success, psychological well-being, and adoption of healthy behaviors. Our knowledge concerning factors associated with FCF, including those that may be targeted with interventions to improve outcomes, remai...
Article
Acceptance-based behavioral therapies for obesity (ABTs) may be superior to standard behavioral therapies but have not been adequately tested with American Indians (AIs). Neurocognitive function is also unexamined in relation to behavioral weight loss among AIs despite findings that neurocognition predicts outcomes in general samples, may help expl...
Article
As evidenced through classic Pavlovian learning mechanisms, environmental cues can become incentivized and influence behavior. These stimulus-outcome associations are relevant in everyday life but may be particularly important for the development of impulse control disorders including addiction. Rodent studies have elucidated specific learning prof...
Article
Full-text available
Background: Adverse childhood experiences (ACEs) and obesity are independently associated with brain/neurocognitive health. Despite a growing emphasis on the importance of early life adversity on health, the relationship between ACEs and neurocognition in adults with overweight/obesity is unclear. The objective was to examine associations between...
Article
Full-text available
Background: Exclusive breastfeeding for 6 months is recommended; however, women with obesity have lower exclusive breastfeeding rates than their normal weight peers. The impact of the timing of maternal excess adiposity onset is unknown. Research Aim: We examined whether the timing of onset of excess weight was related to exclusive breastfeeding d...
Chapter
During the developmental period of 6–12 months, infants deepen and solidify their developing relationships. By 6 or 7 months of age, attachments to and preference for primary caregivers are observable. Infants also begin to exhibit fear of strangers and actively seek proximity to attachment figures during this time. Chapter 4 presents research on t...
Article
Full-text available
Obesity is a global epidemic, yet successful interventions are rare. Up to 60% of people fail to achieve clinically meaningful, short-term weight loss (5-10% of start weight), whereas up to 72% are unsuccessful at achieving long-term weight loss (5-10% loss for ≥5years). Understanding how biological, cognitive, and self-regulatory factors work toge...
Article
This study examined relations between multiple measures of maternal iron status assessed 3 months post-partum, and infant processing speed (longest look during visual habituation), memory (novelty preference), attention (heart rate changes), and neural response variability (in auditory event-related potentials) at 3 and 9 months. Plasma iron was as...
Article
The interactions between attention and stimulus encoding in infancy were examined using heart rate (HR) and visual habituation measures. At 3, 6, and 9 months of age, infants (N = 119) were habituated to an adult face; longest look (LL) duration was measured as an indicator of encoding speed. Three groups were formed based on LL change from 3 to 9...
