AB  - Face perception depends both on the face and on the individual who perceives it. 
      Some factors such as gender, ethnicity or age may influence face perception 
      processing. For instance, recognition memory for faces of one's own age group is 
      often superior to memory for other-age group faces. This bias is known as the 
      Own-Age-Bias (OAB). OAB has been extensively studied in healthy subjects. 
      However, to our knowledge, no article has been published on elder adults 
      suffering from Alzheimer Disease (AD). Therefore, the present research aimed at 
      studying the OAB in patients with AD in comparison with healthy old adults and 
      healthy young adults. Sixty participants were included: 20 young adults, 20 
      healthy old adults, and 20 elder patients who met NINCDS-ADRDA criteria for 
      probable AD. Participants performed an age estimation task followed by a face 
      recognition task. Indeed, for each photograph, subjects were asked to say if the 
      face looked young or old and to give a yes/no judgment of familiarity (after an 
      encoding phase). Participants also completed a questionnaire assessing their 
      frequency of contact with young and old adults. Although estimates of sensitivity 
      indicated no age bias in AD patients, when memory bias was corrected according to 
      their performance we found evidence in favor of an OAB in this group. Both 
      healthy groups presented an OAB, in particular when the corrected memory bias was 
      considered. However, no significant correlations were found between their 
      frequency of contact with young/older people and the number of correctly 
      identified faces, false alarms, sensitivity and corrected memory bias. Therefore, 
      although AD patients present a deficit in face-memory, they still present memory 
      bias towards same-age group faces when their difficulties in face memory are 
      controlled.
