Categorical and dimensional approaches to the developmental relationship between ADHD and irritability
BACKGROUND: Attention deficit hyperactivity disorder (ADHD) and irritability commonly co-occur, and follow similar developmental trajectories from childhood to adolescence. Understanding of the developmental relationship between these co-occurrences is limited. This study provides a longitudinal assessment of how ADHD diagnostic status and symptom patterns predict change in irritability. METHODS: A community sample of 337 participants (45.2% ADHD…
Enhancing neuroimaging genetics through meta-analysis for Tourette syndrome (Enigma-TS)
Tourette syndrome (TS) is characterized by multiple motor and vocal tics, and high-comorbidity rates with other neuropsychiatric disorders. Obsessive compulsive disorder (OCD), attention deficit hyperactivity disorder (ADHD), autism spectrum disorders (ASDs), major depressive disorder (MDD), and anxiety disorders (AXDs) are among the most prevalent TS comorbidities. To date, studies on TS brain structure and function have been limited in size wit…
Value of Self‐Disclosure to Parents and Peers During Adolescence
Self-disclosure is a crucial part of developing close interpersonal relationships during adolescence. In particular, sharing information with a greater depth of intimacy is thought to strengthen social bonds and thus support mental health. The current study investigated the value for different depths of self-disclosures to close others (mothers and best friends) during adolescence and its association with mental health and well-being. Fifty-four …
Analysis of structural brain asymmetries in attention‐deficit/hyperactivity disorder in 39 datasets
OBJECTIVE: Some studies have suggested alterations of structural brain asymmetry in attention-deficit/hyperactivity disorder (ADHD), but findings have been contradictory and based on small samples. Here, we performed the largest ever analysis of brain left-right asymmetry in ADHD, using 39 datasets of the ENIGMA consortium. METHODS: We analyzed asymmetry of subcortical and cerebral cortical structures in up to 1,933 people with ADHD and 1,829 una…
Evidence accumulation during perceptual decisions in humans varies as a function of dorsal frontoparietal organization
Animal neurophysiological studies have identified neural signals within dorsal frontoparietal areas that trace a perceptual decision by accumulating sensory evidence over time and trigger action upon reaching a threshold. Although analogous accumulation-to-bound signals are identifiable on extracranial human electroencephalography, their cortical origins remain unknown. Here neural metrics of human evidence accumulation, predictive of the speed o…
Different Scales for Different Frames
Consumers respond more favorably to positively framed attribute information than to negatively framed attribute information, a finding that has been attributed to the affective associations evoked by each frame. We contend that framing effects also depend on the range and level of reference values used to evaluate attribute information. When the range of reference values is narrower for a positive frame than a negative frame, attribute values abo…
