Is executive dysfunction a potential contributor to the comorbidity between basic reading disability and attention-deficit/hyperactivity disorder?

Our study is one of the few to analyze executive functioning (EF) in a comprehensive, multi-modal fashion as a potential contributor to the comorbidity between attention-deficit/hyperactivity disorder (ADHD) and basic reading disability (RD). We included multiple, traditional, neuropsychological measures of EF, along with the Behavior Rating Inventory of Executive Function (BRIEF) questionnaire, to assess inhibit, shift, working memory (WM), planning, generation fluency, and problem-solving. Participants included 263 children, ages 8-12 years, with RD, ADHD, RD/ADHD, and typically developing controls. When using the traditional measures in a 2 × 2 MANCOVA, we found both RD and ADHD had poor cognitive EF in most areas at the group level, with phonological loop deficits being more specific to RD and behavioral regulation deficits being more specific to ADHD. Children with RD/ADHD performed comparably to those with RD and ADHD alone. Results were similar on the BRIEF. In contrast, only WM predicted both basic reading and inattention when the data were assessed in a continuous fashion. It also explained the correlations between basic reading and inattention, being worthy of longitudinal research to determine if it is a shared contributor to RD/ADHD. When comparing hypotheses as to the nature of RD/ADHD, we found the multiple deficit hypothesis was better supported by our EF data than the phenocopy hypothesis or the cognitive subtype hypothesis.

How Does Alcohol Consumption Affect Perceptions of One's Own and a Drinking Partner's Ability to Consent to Sexual Activity?

In this naturalistic study, our aim was to examine the extent to which alcohol consumption affected perceptions of one's own and one's friend's ability to consent to sexual activity. We surveyed 160 adult bargoers in pairs about their own and their friends' alcohol consumption, intoxication symptoms, and ability to consent to sexual activity. On average, participants reported consuming 4.97 drinks, rated themselves at the legal limit for driving, reported one intoxication symptom, and had a blood alcohol concentration (BAC) just over .08. However, few thought they or their friend had diminished cognitive function. Accordingly, most indicated that they could consent to sex (93%) and their friend could consent to sex (87%). Number of drinks people reported consuming, self-reported intoxication levels and symptoms, and BACs were significantly correlated; however, none of these measures was significantly related to individuals' perceptions of their own or their friends' ability to consent to sexual activity. Finally, those in man-man pairs were significantly more likely than those in woman-woman pairs to indicate they would allow their friend to have sex if approached by an interested party. These findings have potential implications for prevention programming and for legal cases involving individuals who engage in sexual activity while intoxicated.
