Abstract:
Ageing leads to difficulties with lexical access, which refers to one's ability to retrieve a word from memory. These difficulties typically occur around the age of 40 or 50 years old (Kavé & Knafo-Noam, 2015), and manifest as word-finding difficulties (Burke & Mackay, 1997; Kavé & Knafo-Noam, 2015; Marini & Andreetta, 2016; Mortensen et al., 2006). Verbal fluency is a way of measuring lexical access (Whiteside et al., 2016) and this ability has been found to decline with age, with an earlier onset and faster decline for semantic fluency compared to letter fluency (Gordon et al., 2018; Kavé & Knafo-Noam, 2015; McDowd et al., 2011). Verbal fluency tasks can reveal dementia-related deficits, showing that some people develop difficulties with lexical access beyond that associated with healthy ageing (Henry et al., 2004; Henry & Crawford, 2004). Therefore, verbal fluency has been proposed as a neuropsychological marker for Mild Cognitive Impairment and dementia (McDonnell et al., 2020; ...
