Barton JJS et al. – Prosopagnosic subjects showed reduced visual recognition of cars after adjusting for verbal semantic scores. The authors conclude that visual recognition is highly correlated with verbal semantic knowledge, that formal measures of verbal semantic knowledge are a more accurate gauge of expertise than self–ratings, and that verbal semantic knowledge can be used to adjust tests of visual recognition for pre–morbid expertise in prosopagnosia.


Exclusive Author Commentary
Jason J. S. Barton, 10/23/09

This project was undertaken to advance our attempts to address an ongoing debate in face recognition research: are faces special and unique? In prosopagnosia this translates to a question of whether a patient's recognition deficit is truly limited to faces. However, the sophistication of recognition depends on prior experience with and interest in specific types of objects. Although most humans are experts in face recognition, the same cannot be said for cars, birds, etc. Our goal was to try to find a non-visual way of indexing car expertise, which would then allow us to predict how many cars a subject should be able to recognize visually. The relationship between verbal and visual knowledge proved to be very robust in healthy subjects, allowing us to show that as a group our six prosopagnosic patients scored lower than expected for their level of expertise. On an individual basis, this test will work best for patients who have some car expertise, as it is limited by floor effects for non-expert subjects. This test is available online and for downloading if you write to the corresponding author.
