abstract
Previous research has shown that faces coded as pixel­based images may
be constructed from an appropriately weighted combination of statistical
``features'' (eigenvectors) which are useful for discriminating members of
a learned set of images. We have shown previously that two of the most
heavily weighted features are important in predicting face gender. Using
a simple computational model, we adjusted weightings of these features
in more masculine and more feminine directions for both male and fe­
male adult Caucasian faces. In Experiment 1, cross­gender face image
alterations (e.g., feminizing male faces) reduced both gender classifica­
