Adaptation effects have been observed and investigated for many different facial attributes (see Strobach & Carbon, 2013 for a review) and can be considered as evidence for the plasticity of our perceptual and memory system. However, this evidence in the face adaptation literature is limited to younger adults (YAs). Therefore, 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 from age and does occur in healthy older adults (OAs) as well. Since, among others, the ability to integrate newly acquired information is impaired in OAs (Faubert, 2002) we propose that face adaptation effects are less pronounced in healthy OAs in comparison to YAs. To investigate the face adaptation effect, we refer to studies of Mueller et al. (2021). The authors investigated face adaptation effects for non-configural brightness information. They were able to 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”. We discuss the results of the present study in YAs and OAs in the context of plasticity of the perception and memory system.
