Inclusion criteria
Developmental prosopagnosic participants will be included if they are... * aged 18-90, * have lifelong histories of face recognition difficulties that impact their everyday life (i.e., not associated with some event such as a stroke, seizure, etc) * score significantly below the mean on the famous faces test and Cambridge Face Memory Test
Exclusion criteria
Participants will be excluded from the study if they... * have a history of a significant neurological disorder including hydrocephalus, stroke, moderate to severe traumatic brain injury (TBI), severe neuromuscular diseases, or severe hypoxia due to cardiac arrest. * have impairments that interfere with cognitive performance, such as uncorrected hearing or vision, lack of English proficiency, musculoskeletal or other issues * have psychiatric disorders, such as schizophrenia, major depressive disorder, bipolar disorder, chronic intractable obsessive-compulsive disorder, or agoraphobia. * We will exclude individuals who are currently dependent on alcohol or other substances, as this may negatively impact cognitive performance. * We will exclude participants who currently are, or within the last 6 months, participating in a behavioral or pharmacological intervention. * Patients with a history of mild TBI or simple concussion will not be excluded as long as it was \> 6 months ago and as long as they have not had repeated concussions (\>5) * We will include individuals with a diagnosis of ADHD as long as their medication has been consistent for the past 6 months.
