The creation and validation of the Developmental Emotional Faces Stimulus Set.
The Developmental Emotional Faces Stimulus Set (DEFSS) is designed to provide a standardized set of emotional stimuli that includes both child and adult faces and that has been validated by participants across a wide range of ages. This article describes the creation and validation of the DEFSS, which includes 404 validated facial photographs of people between 8 and 30 years old displaying five different emotional expressions: happy, angry, fearful, sad, and neutral. The emotions in all photographs were identified correctly by 86 % of the raters (minimum 55 %), and validity did not vary as a function of the age group of the model or of the raters, indicating that the pictures are equally appropriate for use across the entire age range. Strengths and limitations of the DEFSS are discussed.
