Better recognised on older face prototypes. There was no clear pattern for surprise and fear. This may be due to differences in the intensity/clarity of expressions that the child models produced compared to the adult models. Anecdotally, we noticed that children were more likely to exaggerate expressions for the photographs, particularly the angry expression. Alternatively, it may be that certain expressions are more readily recognised on child faces as opposed to adult faces due to age related differences in the shape of facial features [8]. In conclusion, we found no evidence of an own-age bias in emotion recognition in child and adult participants using younger child, older child, and young adult emotional expression prototypes. Instead we found that emotions were recognised as accurately on child age and adult age faces by all age groups. These results strongly suggest a lack of own-age bias in emotion recognition in children. However further studies with greater numbers of adult subgroups and aPLOS ONE | DOI:10.1371/journal.pone.0125256 May 15,10 /No Own-Age Advantage in Children’s Recognition of Emotionbetter match between the ages of adult participants and the ages of adult face stimuli, will be needed to confirm a lack of own-age bias in emotion recognition in adults.AcknowledgmentsWe thank journal.pone.0174109 staff at At-Bristol for supporting our data collection activities.
