Picture database of emotional facial expressions: Technical Report

Abstract

The objective of the present study was to develop a set of pictures with different emotional facial expressions to be used in empirical studies. The photographs included in the database were chosen from six face databases on the basis of empirical studies in which 1) a large student sample judged the pictures on emotional category, expressiveness and quality of the photograph and 2) trained experts judged the pictures based on the facial action coding system (FACS), (Ekman & Friesen, 1978). Based on the two ratings, three categories of facial expressions were formed for 204 pictures: positive, negative and neutral with 68 picture in each category.
