Adaptation effects have been observed for many dimensions of faces and are a sign for the plasticity of our perceptual and memory system. However, this evidence in the face adaptation literature is mostly limited to younger adults (YAs). In the present study, we aim to examine if this plasticity is specific to YAs or if it is at least to some degree independent of age. Since, among others, the ability to integrate newly acquired information is impaired in older adults (OAs) we hypothesised that face adaptation effects are less pronounced in healthy OAs in comparison to YAs. We induced face adaptation effects for non-configural brightness information in YAs and OAs in online experiments. Our studies show that exposure to an image of a familiar face with strongly manipulated brightness (increased or decreased) alters the perception of subsequent face stimuli: original, non-manipulated face images then appear to be manipulated, while images similar to the adaptor are perceived as “original”. However, inconsistent with our hypotheses, these adaptation effects occur to a similar degree across age groups, demonstrating adaptation effects not only in YAs, but also in OAs. According to our knowledge, this is one of the first demonstrations of face adaptation effects in an older age group. We discuss the results in the context of plasticity of the visual system.
