INTRODUCTION: Social cognition is commonly assessed by identification of emotions in facial expressions. Presence of colour, a salient feature of stimuli, might influence emotional face perception. METHODS: We administered 2 tests of facial emotion recognition, the Emotion Recognition Test (ER40) using colour pictures and the Penn Emotional Acuity Test using monochromatic pictures, to 37 young healthy, 39 old healthy and 37 @entity161 @entity1 . RESULTS: Among young healthy individuals recognition of emotions was more accurate and faster in colour than in monochromatic pictures. Compared to the younger group, older healthy individuals revealed impairment in identification of sad expressions in colour but not monochromatic pictures. @entity161 @entity1 showed greater impairment in colour than monochromatic pictures of neutral and sad expressions and overall total score compared to both healthy groups. @entity1 showed significant correlations between @entity73 and perception of emotion in colour but not monochromatic pictures. CONCLUSIONS: Colour enhances perception of general emotional clues and this contextual effect is impaired in healthy ageing and @entity161 . The effects of colour need to be considered in interpreting and comparing studies of emotion perception. Coloured face stimuli may be more sensitive to emotion processing impairments but less selective for emotion-specific information than monochromatic stimuli. This may impact on their utility in early detection of impairments and investigations of underlying mechanisms.
