A 2D model of face evaluation. (A) Examples of a face varying on the two orthogonal dimensions, trustworthiness and dominance. The face changes were implemented in a computer model based on trustworthiness (study 3) and dominance judgments (study 4) of 300 emotionally neutral faces. The extent of face exaggeration is presented in SD units. (B) Mean trustworthiness judgments of faces (study 5) generated by the trustworthiness model. (C) Mean dominance judgments of faces (study 6) generated by the dominance model. The judgments were made on 9-point scales. Error bars show standard error of the mean.
