Abstract/Results: | ABSTRACT:
It has been suggested that familiar and unfamiliar faces employ different processing mechanisms with familiar faces recognised via an invariant structural code and unfamiliar faces from the pictorial codes contained within an image of a face [Bruce and Young, 1986, British Journal of Psychology, 77, 305-327]. Recent research has suggested however that perhaps all faces, including familiar faces are recognised through pictorial coding [Longmore, Liu and Young, 2008, Journal of Experimental Psychology: Human Perception and Performance, 34, 77-100]. We present a series of experiments showing that when recognition across viewpoints (e.g. full-face to profile) of a face is required, recognition does indeed appear to be tied to the images studied. However, using the same experimental paradigm, evidence from ERPs indicates that there might be some degree of facilitation in learning two viewpoints (frontal and profile) when recognition on a previously unseen view (three-quarter) is required compared to learning a single view. This suggests that some kind of structural information is being extracted during learning that facilitates recognition from novel views. It would appear that whilst the behavioural data indicates a predominately pictorial basis for the recognition of newly learnt faces, neuro-correlates suggest greater levels of invariance.
