We examined psychiatric comorbidities moderation of a 2-site double-blind randomized clinical trial of theta/beta-ratio (TBR) neurofeedback (NF) for attention deficit hyperactivity disorder (ADHD). Seven-to-ten-year-olds with ADHD received either NF (n = 84) or Control (n = 58) for 38 treatments. Outcome was change in parent-/teacher-rated inattent...

Introduction: We examined psychiatric comorbidities moderation of a 2-site double-blind randomized clinical trial of theta/beta-ratio (TBR) neurofeedback (NF) for attention deficit hyperactivity disorder (ADHD). Methods:Seven-to-ten-year-olds with ADHD received either NF (n=84) or Control (n=58) for 38 treatments. Outcome was change in parent-/tea...

Objective: This pilot placebo-controlled trial (NCT00965068, 07/28/2009) explored effects of cholesterol supplementation on autism spectrum disorder (ASD) symptoms in children with abnormally low cholesterol. Method: Fifteen children age 4-12 with ASD and cholesterol <5th percentile for age/sex were randomized to 225 mg cholesterol vs. matched plac...

Objectives Childhood ADHD commonly co-occurs with comorbidities, suggesting that ADHD treatments should consider these. A 2-site, double-blind RCT comparing neurofeedback (NF) to control found delayed treatment effects. We examined whether comorbid diagnoses enhanced or impaired NF effects. Methods Children aged 7-10 years with DSM-5–defined ADHD p...

Objective To Explore whether subtypes and comorbidities of attention-deficit hyperactivity disorder (ADHD) induce distinct biases in cognitive components involved in information processing. Method Performance on the Integrated Visual and Auditory Continuous Performance Test (IVA-CPT) was compared between 150 children (aged 7 to 10) with ADHD, grou...

Objective. To Explore whether subtypes and comorbidities of attention-deficit hyperactivity disorder (ADHD) induce distinct biases in cognitive components involved in information processing. Method. Performance on the Integrated Visual and Auditory Continuous Performance Test (IVA-CPT) was compared between 150 children (aged 7-10 years) with ADHD,...

Computational models, in conjunction with (neuro)cognitive tests, are increasingly used to understand the cognitive characteristics of participants with attention-deficit hyperactivity disorder (ADHD). We reviewed 50 studies from a broad range of cognitive tests for ADHD to synthesize findings and to summarize the new insights provided by three com...

We investigated aging effects in a task-switch paradigm with degraded stimuli administered to college students, 61-74 year olds, and 75-89 year olds. We studied switch costs (the performance difference between task-repeat and task-switch trials) in terms of accuracy and mean reaction times (RTs). Previous aging research focused on switch costs in t...

We experimentally study whether individuals adopt negative beliefs about others' intentions to justify egoistic behavior. Our first study compares the beliefs held by players with such an incentive to the beliefs of neutral observers and finds no evidence that individuals engage in “strategic cynicism.” This contrasts with other recent evidence dem...

ADHD individuals respond differently to stimulants The effects of stimulants on cognition and decision processes are explored Objectives: 1) To identify the cognitive components that differentiate ADHD from controls on neurocognitive tests 2) To account for ADHD heterogeneity 3) To quantify on which cognitive components stimulants exert their effec...

We experimentally study settings where an individual may have an incentive to adopt negative beliefs about another’s intentions in order to justify egoistic behavior. Our first study uses a game in which a player can take money from an opponent in order to prevent the opponent from subsequently causing harm. We hypothesize that players will justify...
