Throughout childhood and adolescence, humans experience marked changes in cortical structure and cognitive ability. Cortical thickness and surface area, in particular, have been associated with cognitive ability. Here we ask the question: What are the time-related associations between cognitive changes and cortical structure maturation.…

Episodic prospection is the ability to mentally simulate personal future events that are rich in contextual detail and plausible for the individual. It therefore incorporates episodic information (who, what, where, and when of a particular event), as well as details about one's self (e.g., knowledge, goals, motivations and desires). The ability to…

Adult neuroimaging studies have demonstrated dissociable neural activation patterns in the visual cortex in response to letters (Latin alphabet) and numbers (Arabic numerals), which suggest a strong experiential influence of reading and mathematics on the human visual system. Here, developmental trajectories in the event-related potential (ERP)…

Social-cognitive and emotional factors as well as behavior problems contribute to the social difficulties experienced by many students with or at high risk for emotional and behavioral disorders (EBDs). The way that teachers and peers treat and respond to these students can either mitigate or exacerbate their challenges in establishing and…

During adolescence, students experience a variety of biological changes in their bodies and brains. This Alliance for Excellent Education report argues that by understanding these changes--as well as the science behind student learning and development--education leaders can take advantage of this second critical window of development to support…

Background: Individuals with fragile-X syndrome exhibit developmental delay, hyperexcitation and social anxiety; they also show lack of attention and hyperactivity. Few studies have investigated whether levels of functioning change with increasing age. Here, we explored developmental changes across adolescence in the cognitive and behavioural…

Adolescence is a developmental period often characterized as a time of impulsive and risky choices leading to increased incidence of unintentional injuries and violence, alcohol and drug abuse, unintended pregnancy, and sexually transmitted diseases. Traditional neurobiological and cognitive explanations for such suboptimal choices and actions…

Onset of psychosis may be associated with abnormal adolescent neurodevelopment. Here we examined the neurocognitive profile of first-episode, adolescent onset psychosis (AOP) as compared to typically developing adolescents, and asked whether neurocognitive performance varied differentially as a function of age in the cases compared with controls.…

During childhood and adolescence, ongoing white matter maturation in the fronto-parietal cortices and connecting fiber tracts is measurable with diffusion-weighted imaging. Important questions remain, however, about the links between these changes and developing cognitive functions. Spatial working memory (SWM) performance improves significantly…

Because of ongoing neuromaturation, youth with chronic alcohol/substance use disorders (AUD/SUD) are at risk for cognitive decrements during young adulthood. We prospectively examined cognition over 10 years based on AUD/SUD history. Youth (N = 51) with no AUD/SUD history (n = 14), persisting AUD/SUD (n = 18), or remitted AUD/SUD (n = 19) were…

Classic theories of self-development suggest people define themselves in part through internalized perceptions of other people's beliefs about them, known as reflected self-appraisals. This study uses functional magnetic resonance imaging to compare the neural correlates of direct and reflected self-appraisals in adolescence (N = 12, ages 11-14…

Serious depression in parents and caregivers can affect far more than the adults who are ill. It also influences the well-being of the children in their care. The first joint Working Paper from the National Scientific Council on the Developing Child and the National Forum on Early Childhood Policy and Programs summarizes recent evidence on the…

Because the brains of 12-14 year olds are in a slow-growth period, middle schools should concentrate on developing maturity in existing cognitive skills rather than on introducing new skills. (IRT)

Noting that understanding a child's brain and the way it develops is the key to understanding learning, this book explores the relationship between brain physiology and children's learning processes. The book first translates the most current scientific theories on nervous-system development into practical information for parents. It then details…
