Purpose: Researchers in the cognitive sciences have identified several key training strategies that support good encoding and retention of target information. These strategies are retrieval-based practice, also known as learning through testing, and spaced practice. The recent resurgence of research on retrieval-based and spaced practice has been…

Jaw movement patterns were examined longitudinally in a 3-year-old male with childhood apraxia of speech (CAS) and compared with a typically developing control group. The child with CAS was followed for 8 months, until he began accurately and consistently producing the bilabial phonemes /p/, /b/, and /m/. A movement tracking system was used to…

Background: Children with speech disorder are a heterogeneous group (e.g. in terms of severity, types of errors and underlying causal factors). Much research has ignored this heterogeneity, giving rise to contradictory intervention study findings. This situation provides clinical motivation to identify the deficits in the speech-processing chain…

A treatment program is described which successfully improved the speech of a 57-year-old apraxic patient. The program was composed of physiologic (nonspeech) and phonetic (articulatory) tasks that began with oroneuromotor control activities and progressed to consonant-vowel syllable, word, and sentence drills, with all activities paced by a…
