Adults can be adapted to a particular facial distortion in which both eyes are shifted symmetrically (Robbins, R., McKone, E., & Edwards, M. (2007). Aftereffects for face attributes with different natural variability: Adapter position effects and neural models. Journal of Experimental Psychology: Human Perception and Performance, 33, 570-592), but they do not show as great adaptation to an asymmetrical eye distortion. We adapted children and adolescents to symmetrical and asymmetrical eye distortions and measured the aftereffects. Children (aged 6-12, mean age 9 years) showed larger aftereffects than adolescents (aged 13-18, mean age 15 years) and demonstrated aftereffects of a similar magnitude for both asymmetrical and symmetrical distortions. Adolescents only showed aftereffects for symmetrical distortions. We propose that children may have a more flexible face norm and neural responses that allow a broader range of adapted states compared to adolescents. © 2010 Elsevier Inc.
