Impaired holistic processing in congenital prosopagnosia

► Congenital prosopagnosic individuals outperform controls on face perception task. ► This results from reliance on local rather than global face processing. ► A local bias is also evident in a task involving processing of non-faces stimuli. ► Impaired face recognition is correlated with increased local bias. ► An impairment in global processing may underlie congenital prosopagnosia.
