Non-acted emotional face  expressions: OpenFace vs population evaluations and effects  of hormonal contraceptives on evaluations  of emotional face expressions

This study explored to what extent OpenFace software evaluations of non-acted emotional face expressions to Ekman (1970)’s six basic emotions based on AUs mappings overlap with population evaluations of the same expressions. The second part of this study analyzed the effects of hormonal contraceptives (HCs) and natural menstrual cycles on the evaluations of non-acted emotional face expressions. 78 participants between the ages of 17 and 44 (M = 22.3) were analyzed in the study, which resulted in the finding of a medium effect sized overlap between the OpenFace evaluations and population evaluations. Diverse outcomes were found for the effects of women who use HCs and women who have natural menstrual cycles on the evaluations of non-acted facial expressions, with HCs having a significant effect on the evaluation of non-acted disgusted face expressions only. More research should be done to find more clear correlations and underlying mechanisms of evaluating non acted emotional face...Show moreThis study explored to what extent OpenFace software evaluations of non-acted emotional face expressions to Ekman (1970)’s six basic emotions based on AUs mappings overlap with population evaluations of the same expressions.
