This study will examine the effectiveness of a cognitive training intervention targeting face recollection, repetition lag training, at improving face recognition in Developmental Prosopagnosia.

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

• have psychiatric disorders, such as schizophrenia, major depressive disorder, bipolar disorder, chronic intractable obsessive-compulsive disorder, or agoraphobia.
