Age-group differences in interference from young and older emotional faces

Human attention is selective, focusing on some aspects of events at the expense of others. In particular, angry faces engage attention. Most studies have used pictures of young faces, even when comparing young and older age groups. Two experiments asked: (1) whether task-irrelevant faces of young and older individuals with happy, angry, and neutral expressions disrupt performance on a face-unrelated task; (2) whether interference varies for faces of different ages and different facial expressions; and (3) whether young and older adults differ in this regard. Participants gave speeded responses on a number task while irrelevant faces appeared in the background. Both age groups were more distracted by own- than other-age faces. In addition, young participants' responses were slower with angry than happy faces, whereas older participants' responses were slower with happy than angry faces in the background. Factors underlying age-group differences in interference from emotional faces of different ages are discussed.
