The evolution of speech required the development of a coordinated action between visual (movement of the lips) and auditory signals in a rhythmic fashion to produce "visemes" (visual movements of the lips that correspo...

Reading trustworthiness in faces without recognizing faces.

We show that developmental prosopagnosics with severe impairments in both memory for faces and perception of facial identity can make normal trustworthiness judgements of novel faces. We tested four prosopagnosics on three different face sets. The first set consisted of faces that varied on multiple dimensions and that have been used to demonstrate impairments in trustworthiness judgements of p...

FACES Evolving faces from principal components

A system that uses an underlying genetic algorithm to evolve faces in response to user selection is described. The descriptions of faces used by the system are derived from a statistical analysis of a set of faces. The faces used for generation are transformed to an average shape by defining locations around each face and morphing. The shape-free images and shape vectors are then separately sub...
