There certainly is substantial evidence that individuals with ADHD perform poorer than others – as a group – on a number of executive functioning tasks that require planning, organizational skills, inhibiting responses (as assessed through tasks such as the Stroop test), decision making, working memory and other Frontal lobes executive functions. His theory is generating significant amounts of research and it is likely that our conceptualization of ADHD will continue to evolve in response to new findings. […]
