Although there is a large amount of research examining the perception of emotional facial expressions, almost all of this research has focused on the perception of adult facial expressions. There are several excellent stimulus sets of adult facial expressions that can be easily obtained and used in scientific research, but there is no  stimulus set of child affective facial expressions. In order to fully understand how humans respond to and process affective facial expressions, it is important to have this understanding across a variety of means. The Child Affective Facial Expressions Set (CAFE) is the first large and representative set of children posing a variety of affective facial expressions that can be used for scientific research. The set is made up of nearly 1200 photographs of over 100 children  (ages 2-8) making 7 different facial expressions - happy, angry, sad, fearful, surprise, neutral, and disgust. (author abstract)
