    Determinants of estimated face composite quality
    (2010) Schmidt, Heike Christine; Tredoux, Colin
    This thesis addresses the evaluation of an investigative tool commonly used by police forces around the world, namely a face composite or facial likeness. The process of constructing a composite involves a number of cognitive elements, all of which contribute to the final composite quality. This thesis examines elements of the construction process and assessment of the final composite quality in research and practice. There are three main aspects to the empirical work reported here. The first, consisting of two experimental studies, investigates the possibility of reinstating context as a way of improving composite quality. The second examines composite construction and use within the South African Police Service. The third examined the measurement of composite quality itself.
