“…They also do not show the phonemic confusability effect (i.e., better memory for phonemically dissimilar vs. rhyming words) that is evident at an early stage in normal readers (Byrne & Shea, 1979;Jorm, 1983;Mann, Liberman, & Shankweiler, 1980), although the effect may emerge in poor readers in early adolescence (Johnston, 1982;Siegel & Linder, 1984). Normal readers show a reduction in phonemic confusability with increasing age, probably because of increased precision of phonemic discrimination (Olson, Davidson, Kliegl, & Davies, 1984). Finally, phoneme segmentation and awareness tasks, as well as rhyming skill, have been shown not only to differentiate good and poor readers (Bradley & Bryant, 1983;Mann, 1984;Share, Jorm, Maclean, & Matthews, 1984;Snowling et aI., 1986;Stanovich, 1988a;Wagner & Torgesen, 1987), but also to be good predictors of future reading ability (Adams, 1990;Goswami, 1990;Mann, 1993;Mann & Brady, 1988;Share et aI., 1984;Stanovich et aI., 1984).…”
