Working memory and information processing in ADHD: Evidence for directionality of effects.

ABSTRACT:

Objective

Children with ADHD demonstrate impaired performance on a wide range of neuropsychological tests. It is unclear, however, whether ADHD is associated with many neurocognitive deficits or whether a small number of impairment(s) broadly influence test performance. The current study tests competing model predictions regarding two candidate causal mechanisms in ADHD: information processing speed and working memory.

Method

A well-characterized sample of 86 children (M_age = 10.52, SD_age = 1.54; 34 girls; 64% Caucasian/Non-Hispanic) with ADHD (n = 45) and without ADHD (n = 41) completed eight fully crossed experimental tasks that systematically manipulated working memory (BF₁₀ = 1.80 × 10⁹³) and information processing speed
