PSYC 309
Todd Handy

Lec 4 NYT article (add prof’s title) Just another face in the crowd, indistinguishable even if it’s your own -face blindness = prosopagnosia: see faces but they all look about the same, can’t recognize people or remember faces -other memory normal: remembering books, names, phone numbers etc -face blindness can be bc stroke or brain injury, but also congenital/developmental -face blind ppl try to recognize ppl in other ways: clothes, gait, voice, hair -prosopognasia fairly common (maybe 2.5%) but often unreported, don’t know you have it -prosopognasia only recently considered medical; most think it’s a ‘bad habit’ or absent minded -face blind ppl still understand facial emotions/cues, gender from face, and agree w/normal ppl about attractiveness of ppl -there is a part of the brain that responds to faces: if you show normal ppl 2 different faces their brain responds differently to each if you show face blind ppl 2 different faces their brain responds same to both -sometimes goes along w/other problems: finding way around, distinguishing cars/dogs from each other -evidence that it is autosomal dominant inherited (everyone w/ face blindness has at least one affected parent, women equally likely to have it, and if one parent is affected 50% chance kid will have it) Lec 4 journal article (add prof’s title) When family looks strange and strangers look normal: a case of impaired face perception and recognition after stroke -patient JS has impaired recognition and distorted perception of faces after a stroke -family member’s faces look distorted, other ppl look normal -showed JS pics of family, celebrities, and strangers and recorded response accuracy, time, and skin conductance; 30 familiar faces 30 unfamiliar (does he care) -3 aspects of face perception impaired: impaired recognition of emotions Poor recognition of familiar faces, even worse for family than celebrity Sees family member’s faces as distorted, repulsive; grandkids overweight and too tan -compared to 3 normal ppl w/same gender, age, and family size (no brain damage or psych problems) -lesion mostly in middle temporal gyrus of right hemisphere -JS’s vision normal -didn’t recognize daughter she knew well, recognized daughter she hadn’t seen in 8 years right away -her grandkids looked repulsive to her -didn’t do well on ‘incomplete letters ‘ test :. Maybe integrative agnosia: can’t integrate parts of object into whole -worst at recognizing sadness -no apparent problems recognizing celebrities, and did NOT mistake celebrity look alikes for the real thing -showed pics of hitler and bin laden: she said they were impersonators Experimental Task -recorded skin conductance response (SCR) while answering, next trial when SCR back to baseline -asked them to recognize all 60 ppl three times: had 3 different pictures of each (so each bloack had diff pics o same people) -background of pics removed :. No context -SCR indicates psychological arousal; looked at SCR amplitude (when there was a response) and averages (response or no response Results -accuracy: controls were 97-99% correct in all categories; JS was 96% correct in unfamiliar (no significant difference from controls), 76% correct in celebrities, 49% correct in family -response time: JS had slower response time than controls; family recognition slower than unfamiliar or celeb Control
