componential

— Humpty Dumpty reports an inability to recognise a familiar face, yet is able to recognise eyes, nose, and mouth and their correct positions, as is also the case with prosopagnosics. In developmental or congenital prosopagnosia […] there are impairments in face identity matching tasks but the ability to identify sex, age, emotional facial expression, and eye gaze direction is preserved. As in these cases, Humpty Dumpty’s account seems to indicate preserved componential but impaired configural processing.
