We recently reported finding asymmetry in the appearance of beauty on the face Zuidel et al., Neuropsychologia, Vol. 33, pp. 649–655, 1995. Here, we investigated whether facial beauty is a stable characteristic (on the owner's very face) or is in the perceptual space of the observer. We call the question `the owner vs observer hypothesis'. We compared identity judgements and attractiveness ratings of observers. Subjects viewed left–left and right–right composites of faces and decided which most resembled the normal face (Experiment 1). Identity judgements (resemblance) are known to be associated with perceptual factors in the observer. Another group viewed the same normal faces and rated them on attractiveness (Experiment 2). In each experiment, there were two separate viewing conditions, original and reversed (mirror-image). Lateral reversal did affect the results of Experiment 1 (confirming previous findings Bennet et al., Neuropsychologia, Vol. 25, pp. 681–687, 1987; Gilbert and Baken, Journal of Anatomy, Vol. 153, pp. 593–600, 1993.) but did not affect the results of Experiment 2. The fact that lateral reversal did not affect the results of Experiment 2 suggests that facial attractiveness is more dependent on physiognomy (of the owner) and less dependent on an asymmetrical perceptual process (in the observer) than is facial identity. The results are discussed in the context of beauty's biological significance and facial processing in the brain.
