Transcript of Prosopagnosia


the inability to recognize faces
Facial Recognition
Life with Face Blindness
Cannot identify family, friends, or self
Identify people by
Hairstyle (can be problematic)
Dislike movies/TV
Elevated anxiety
Relationships severely affected
Face Blindness
By: Mary Kate Healy
How We Recognize
Unique system for face processing
Process holistically
Fusiform Face Area
Head Trauma
Degenerative Diseases
Genetic Prosopagnosia
Pre-experiential Prosopagnosia
Post-experiential Prospagnosia
Can identify the parts, but not the whole
Questions to be Answered
What is the full facial recognition process?
What process or region is impaired in those with Posopagnosia?
Genetically based? Which genes?
Is there any hope for improvement of facial recognition?

What Causes Prosopagnosia?
Related to Dyslexia?
Similar reduction in gray matter
Deficits caused by neural migration patterns
Occipital/Temporal regions
Impairment in the holistic face process
MZ case study
Learn to judge distances of facial features
