Facial caricatures exaggerate the distinctive features of a face and may elevate the recognition of a familiar face. We investigate whether the recognition of facial composites, or pictures of criminal faces, could be similarly enhanced. In this study, participants first estimated the degree of caricature necessary to make composites most identifiable.(More)
Facial composites are pictures of human faces. These are normally constructed by victims and witnesses of crime who describe a suspect’s face and then select individual facial features. Unfortunately, research has shown that composites constructed in this way are not often recognised. In contrast, we are quite good at recognizing complete faces, even if the(More)
We describe a simple psychophysical paradigm for studying figure-ground segregation by onset asynchrony. Two pseudorandom arrays of Gabor patches are displayed, to left and right of fixation. Within one array, a subset of elements form a figure, such as a randomly curving path, that can only be reliably detected when their onset is not synchronized with(More)
We have developed a novel software program called ‘Predict Your Child’ that, given photographs of potential parent faces, generates plausible looking children. The parent photographs are imported into a PCA-based model of facial appearance to give a set of face parameters that can be mixed together to produce offspring faces. The program is intended for(More)
