Dr Jeremy Tree discusses the importance of motion based information in face processing in prosopagnosia

In the second seminar of our cognitive research series Dr Jeremy Tree, from Swansea University, presented some of his latest research investigating factors that affect face processing in prosopagnosia.  As Dr Tree discussed, developmental prosopagnosia refers to patients who experience problems with face recognition from early childhood. Patients are typically able to acknowledge that a face is present but are unable to identify the face. This can be severely debilitating, affecting the recognition of even the most familiar individuals, such as family members or one’s self. Patients with prosopagnosia also fail to discriminate between unknown faces. However recent work by Dr Tree has demonstrated that idiosyncratic facial movements could provide a route to facial identity in prosopagnosia. A case study demonstrated that whilst a patient had impairments in their ability to recognise identity from static facial images they had no problem in their ability to access identity based on their idiosyncratic facial movements. Dr Tree went on to discuss the implications of this in relation to facial recognition explanations in patients with developmental prosopagnosia.
