Testing the effect of dynamic 3D viewing conditions on face similarity perception

Project description

To test the effect of space and time on face similarity judgments, we conducted an online experiment using a triplet odd-one-out task in a static 2D and a dynamic 3D condition. We then trained sparse and deep computational encoding models of human face similarity judgments to investigate the latent representations that underlie their predictions.
