“…For example, a series of studies by Gierut, Morrisette, and colleagues (Gierut & Morrisette, 2012b, 2014Gierut, Morrisette, & Champion, 1999;Morrisette & Gierut, 2002) has found that words coming from dense phonological neighborhoods can improve speech treatment outcomes, but only if certain conditions are met, such as when input cues converge (i.e. phonologically dense words must also be high frequency and early acquired) (Gierut & Morrisette, 2012b) or when phonologically dense words precede or prime words used in treatment (Gierut & Morrisette, 2014). In addition, it has been found that late-acquired words can induce larger amounts of phonological generalization due to treatment than do early-acquired words (Gierut & Morrisette, 2012a).…”
