Abstract

ADHD is a prevalent diagnosis among children and men; however, it also impacts adults and women. Of the many cognitive impairments in ADHD, this study will investigate effort allocation in adults with varying levels of ADHD using the cognitive energetic model. The model postulates that people with ADHD perform worse on those event rates that are fast and slow compared to the medium ones. Within this study, an impairment in effort allocation for adults with varying levels of ADHD symptoms on an online Stroop task is expected. Specifically, it is assumed to find a worse performance on accuracy for the fast event rates, and slower mean reaction time in the slow event rate. The shortcomings of adults with ADHD symptoms on this task would be ascribed to an impairment of their effort allocation function. Further, a difference in performance between the male and female participant groups is expected. These assumptions were tested with first-year psychology students from the University of Groningen (N = 71) who responded to the CAARS questionnaire assessing ADHD symptoms and a Stroop task. Following the statistical analysis, the manipulation of event rate was not related to the level of ADHD. Neither was there any effect of gender on the task. This indicates that the required effort allocation might not be impaired for this sample when measured with an online Stroop task. The null findings can help future research choose other tasks to measure effort allocation in people with ADHD symptoms. Keywords: ADHD, effort allocation, cognitive energetic model, state regulation deficit, university students, online Stroop task, CAARS
