“…Category clustering of items in recall also shows an increasing trend with increasing age, both in single-trial free recall (Bousfield et al, 1964;Handler & Stephens, 1967;Vaughan, 1968) and in multitrial free recall (Cole et al, 1971;Moely, Olson, Halwes, & Flavell, 1969;Nelson, 1969;Rosner, 1971;Yoshimura, Moely, & Shapiro, 1971).
