Abstract
The embodiment perspective holds that the sensory, cognitive, and motor systems are necessarily intertwined for coherent action-perception behavior. These systems decline with advanced age, altering the embodiment of older adulthood through a reweighting of neural signals based on declines to the body and motor systems (Kuehn et al., Neurosci Biobehav Rev 86:207-225, 2018). Older adults exhibit a characteristic twin-response: (1) decreased weighting of body-action system inputs, and (2) compensatory increases in visual processing and higher-order cognitive processing (Costello and Bloesch, Front Psychol, 8, 2017). This paper recapitulates how aging alters embodiment, and then explores two major paradoxes that result from older adult embodiment. The first is the Body Salience paradox: the more that the body has become explicitly visible to the individual, the less the body has been successfully incorporated into the embodied response. The second is the Exteriority Bias paradox: the less overt physical access older adults have to the world, the more the world will be utilized as an external reference. We resolve these paradoxes by drawing on both experimental findings and phenomenological analyses. We conclude with a broader discussion of how to envision what we call the embodiment equilibrium of older adults, through a joint dialogue of neural network and phenomenological models.
