Around 2% of the general population are born with developmental prosopagnosia (also known as 'face blindness'), a condition characterised by difficulties recognising faces. Often individuals are unaware they have the condition, instead believing they have 'bad memory for faces'. However, prosopagnosia is entirely unrelated to intelligence or broader memory ability. People with developmental prosopagnosia often use other cues to recognise people, such as their hair style or their clothes.
If you think you might have developmental prosopagnosia and would like to find out more / participate in prosopagnosia research, it would be really great to hear from you. Just drop me an email (Richard.Cook.firstname.lastname@example.org) or visit www.troublewithfaces.org to find out more.
