Abstract: Developmental co-ordination disorder (DCD) is characterised by difficulties in motor control from early childhood. Despite children with this condition suffering problems recognising faces, it is unknown if these issues extend into adulthood. We tested this hypothesis through a range of facial identity processing tasks, and assessed the prevalence of developmental prosopagnosia (i.e., lifelong difficulties with faces) in DCD. Strikingly, we found 53% of those with DCD met recently recommended criteria for a diagnosis of prosopagnosia, with 34% acquiring a diagnosis using traditional cognitive task based methods. Moreover, their problems with faces were apparent on both unfamiliar and familiar face memory tests, as well as on a facial perception task (i.e., could they tell faces apart?). These issues remained even after excluding DCD cases with comorbid conditions traditionally associated with difficulties in face recognition, i.e., autism and dyslexia. A substantial proportion of people with DCD therefore suffer severe problems with faces in adulthood that could be considered clinically significant. Moreover, given the high prevalence of prosopagnosia in DCD, and the positive correlation between DCD and prosopagnosia symptoms, there may be a stronger link between developmental prosopagnosia and DCD than previously thought.
