Feature processing and superiority of three-quarter views in face recognition.
The specificity of face recognition is usually related to the hypothesis that it could be based mainly on global processing of the whole face. However, this does not mean that more analytic processes, like the local processing of some features, could not play a role in the recognition process in some circumstances. An experiment was conducted with 18 normal subjects in order to evaluate the role of analytic processes in the recognition of faces viewed from different angles. Makeup was applied to eyes and lips to enhance local processing (local cue). We found a positive effect of the makeup cue, which could be due to better recognition when the shape of eyes and lips are highlighted. Also, we found better recognition with left-sided views compared to right-sided views. Finally, the makeup effect was significant in left three-quarter views but not in right three-quarter views. If this effect is due to analytic processing of some facial features, it could be related to a left hemisphere operation.
