“…For example, ageing is associated with a variety of physical changes to the eye, including presbyopia (Glasser & Campbell, 1998), miosis (Sloane et al, 1988), and loss of retinal photoreceptor and ganglion cells Curcio & Drucker, 1993). In terms of hearing, some degree of presbycusis is estimated to be present in at least 90% of humans by age 80 (Cruickshanks et al, 1998;Rodríguez-Valiente, 2020). The deleterious effects of these changes on sensory reliability are compounded by agerelated alterations in central processing of sensory stimuli (Elliott et al, 1990;Martin & Jerger, 2005;Simpson et al, 1985;Wang et al, 2006).…”
