The ability to infer intentions from observed behavior and predict actions based on this inference, known as intention attribution (IA), has been hypothesized to be impaired in individuals with autism spectrum disorder (ASD). The underlying neural processes, however, have not been conclusively determined. The aim of this study was to examine the…

The centrality of multitasking in teenagers' lives has triggered vast interest in popular and academic discussion. Due to a large inconsistency in the study and multitasking reporting, we endeavoured to better understand and characterize multitasking behaviors. We researched multitasking patterns, prevalence, types, combinations and gender…

Atypical sensory processing has recently gained much research interest as a key domain of autistic symptoms. Individuals with autism spectrum disorder (ASD) exhibit difficulties in processing the temporal aspects of sensory inputs, and show altered behavioural responses to sensory stimuli (i.e., sensory responsiveness). The present study examined…

Of the diagnostic features of autism, relatively little research has been devoted to restricted and repetitive behavior, particularly topographically complex forms of restricted and repetitive behavior such as rigidity in routines or compulsive-like behavior (e.g., arranging objects in patterns or rows). Like vocal or motor stereotypy,…

Background: Numerous studies have examined gene × environment interactions (G × E) in cognitive and behavioral domains. However, these studies have been limited in that they have not been able to directly assess differential patterns of gene expression in the human brain. Here, we assessed G × E interactions using two publically available datasets…

The structure of the human brain changes in several ways throughout childhood and adolescence. Perhaps the most salient of these changes is the strengthening of white matter tracts that enable distal brain regions to communicate with one another more quickly and efficiently. Here, we sought to understand whether and how white matter changes…

This article addresses the question of why the emotions children and adolescents anticipate in the context of hypothetical scenarios have been repeatedly found to predict actual (im)moral behavior. It argues that a common motivational account of this relationship is insufficient. Instead, three links are proposed that connect cognitive…

Background: Impaired cognitive control has been frequently observed in children and young people with attention deficit hyperactivity disorder (ADHD) and might underlie the excessive hyperactivity and impulsivity in this population. We investigated behavioural and electrophysiological indices relevant to one domain of cognitive control; namely…

Progressive developments in scanning technologies over the last decade have led to a surge of new research into the structure and function of the brain and into differences between the brains of teenagers and other adults. This work has not been free of controversy, notably around the question of deficits in the capacity of young people concerning…

It has been hypothesized that sensation seeking and impulsivity, which are often conflated, in fact develop along different timetables and have different neural underpinnings, and that the difference in their timetables helps account for heightened risk taking during adolescence. In order to test these propositions, the authors examined age…

This study examined the relationship between everyday repetitive behavior (primary symptoms of autism) and performance on neuropsychological tests of executive function and central coherence (secondary symptoms). It was hypothesized that the frequency and intensity of repetitive behavior would be positively correlated with laboratory measures of…

A study of 22 children with autism and 19 children with mental retardation found that, when prompted, school-age and adolescent subjects with autism did not differ from children with mental retardation in production of functional play acts and situationally appropriate object substitution, but did produce fewer novel pretend play acts.

Wild parties, late nights, and lots of sex, drugs, and alcohol. Many assume these are the things that define an American teenager's first year after high school. But the reality is really quite different. As Tim Clydesdale reports in "The First Year Out", teenagers generally manage the increased responsibilities of everyday life immediately after…

Experimental research has firmly established the role of expectancies in determining the behavioral consequences of alcohol consumption. To ascertain whether these alcohol expectancies derive from direct pharmacological experience with alcohol or from nonpharmacological, social-learning factors, an adolescent expectancy questionnaire was…

A study examined the cognitive and behavioral profiles in 10 individuals (ages 14-51) with Smith-Magenis syndrome. Results found the individuals showed significant relative weaknesses in sequential processing and strengths in naming a partially completed drawing, identifying things, and in reading/decoding. Behavioral findings indicated…
