title: Face likeability mediates the memory-enhancing effect of face attractiveness in young but not older adults.
abstract: Evidence of effects of face attractiveness on memory is mixed and little is known about the underlying mechanisms of this relationship. Previous work suggests a possible mediating role of affective responding to faces (i.e., face likeability) on the relationship between face attractiveness and memory. Age-related change in social motivation may reduce the relevance of face attractiveness in older adults, with downstream effects on memory. In the present study, 50 young and 51 older participants were presented with face-trait pairs. Faces varied in attractiveness. Participants then completed a face-trait associative recognition memory task and provided likeability ratings for each face. There was a memory-enhancing effect of face attractiveness in young (but not older) participants, which was partially mediated by face likeability. In addition, more attractive and less attractive (compared to moderately attractive) faces were more likely remembered by both young and older participants. This quadratic effect of face attractiveness on memory was not mediated by face likeability. Findings are discussed in the context of motivational influences on memory that vary with age.
