“…Stuart, Vanderhoof-Bilyeu, & Beukelman, 1994; Davidson, Worrall, & Hickson, 2003) and two large spoken corpora (i.e. SUBTLEX, Brysbaert & New, 2009; CELEX, Baayen, Piepenbrock, & Gulikers, 1995), Renvall et al (2013a; b) compared common conversation topics among unimpaired elderly speakers with those of PWA, and compiled lists of most frequent vocabulary items.
