The role of exploratory action in face encoding (2006)
Presentation / Conference Contribution
Liu, C., & Ward, J. The role of exploratory action in face encoding

Research on face recognition has mainly relied on methods where observers are relatively passive viewers of face stimuli. We investigated whether active exploration of 3-D face stimuli could facilitate recognition performance. A yoked design was empl... Read More about The role of exploratory action in face encoding.

Transfer between two- and three-dimensional representations of faces (2006)
Journal Article

Because stereoscopic depth cues are not present in an ordinary photograph, matching a two-dimensional (2-D) photograph to a three-dimensional (3-D) face requires establishing a correspondence between information derived from monocular depth cues and...

Face recognition in pictures is affected by perspective transformation but not by the centre of projection (2006)
Journal Article
Liu, C. H., & Ward, J. (2006). Face recognition in pictures is affected by perspective transformation but not by the centre of projection. Perception, 35(12), 1637-1650. https://doi.org/10.1068/p5545

Recognition of unfamiliar faces is susceptible to image differences caused by angular sizes subtended from the face to the camera. Research on perception of cubes suggests that apparent distortions of a shape due to large camera angle are correctable...
