1. CREATING ARTIFICIAL FACES
A Data-Driven Approach
Torodov et al, 2010 (link) were the first to develop a computational model of social judgements from faces
Using a program called FaceGen they created a database of faces designed to be maximally distinct from one another
These were rated by thousands of participants to provide external validity
Transformations along all other dimensions are controlled for attractiveness
. . .
FACEGEN EXAMPLES: 25 ‘INDIVIDUALS’ MORPHED ALONG 7 DIMENSIONS

FACEGEN EXAMPLES:‘INDIVIDUALS’ AND TRAITS
Attractiveness (Neutral, Low, High)
Extroversion (Neutral, Low, High)
FACEGEN EXAMPLES:‘INDIVIDUALS’ AND TRAITS
Competence (Neutral, Low, High)
Dominance (Neutral, Low, High)
II. PSYCHOMORPH
The problem with artificial faces….
Computational models can create “maximally distinct” faces on each dimension
However, the faces are clearly not real
To overcome this limitation, we use a set of algorithms which have been under development for nearly 20 years (link)
Psychomorph (now called Webmorph) allows us to use these prototypes to transform real faces along the dimensions identified by Todorov
