Final answer:
Prosopagnosia, also known as face blindness, is a condition where individuals cannot recognize faces and may use other cues for identification.
Step-by-step explanation:
The term that describes a deficit in the ability to recognize faces is Prosopagnosia. Also known as face blindness, Prosopagnosia is a neurological disorder stemming from damage to the fusiform gyrus of the brain, which can be present from birth or caused by trauma. Individuals with this condition may utilize alternative cues like the sound of a person's voice, unique facial features, hair color, or mannerisms to identify others. People with prosopagnosia may rely on other cues like voice or distinct facial features to recognize familiar individuals.
