Karolinska Data Set

This face database was created in the Karolinska Institute in Sweden (Lundqvist, Flykt, and Ohman 1998). In our studies, frontal headshots of 66 of the actors’ faces were rated on 14 trait dimensions: attractive, caring, aggressive, mean, intelligent, confident, emotionally stable, trustworthy, responsible, sociable, weird, unhappy, dominant, and threatening. The trait judgments were measured on 9-point scales, ranging from 1 (not at all [trait]) to 9 (extremely [trait]). The rating procedures are described in Oosterhof and Todorov 2008. The respective sample sizes (number of raters per trait judgment) and reliabilities (Cronbach’s alpha) can be found in Table S2 of Oosterhof and Todorov 2008.

If you use these faces, any resulting written work should acknowledge the original source of the faces, Lundqvist, Flykt, and Ohman 1998, and Oosterhof and Todorov 2008. The exact references are:
