Abstract

This study examined the immediate effectiveness of different word form specific cues on picture naming in patients with anomia or apraxia of speech. The aim was to determine which cue (segmental: initial phoneme, subsegmental: mouth-shape of the initial phoneme) facilitates word production depending on the mode of presentation (explicit/implicit) and the underlying impairment of the patient (anomia/apraxia of speech). The results differed between the two patient groups. The anomic patients showed a positive effect of explicit segmental cues only whereas the patients with apraxia of speech were facilitated by explicit and implicit segmental cues as well as by explicit mouth-shape cues.
