Task dissociation in prospective memory performance in individuals with ADHD

OBJECTIVE: The present study investigated, for the first time, event- and time-based prospective memory (PM) in the same sample of adults with ADHD within one paradigm using parallel task constraints. METHOD: A total of 25 individuals with ADHD and 25 matched neurotypical controls completed a computerized version of the Dresden Breakfast Task, which required participants to prepare breakfast following a set of rules and time restrictions. RESULTS: Although groups did not differ in event-based PM, results demonstrated a large-sized impairment in individuals with ADHD in time-based PM. CONCLUSION: Findings suggest a task-specific impairment in PM functioning and are discussed in an executive control framework of neurocognitive functioning in ADHD
