There exist few clinical assessments for limb apraxia, a disorder of learned, purposeful action, that enable clinicians to distinguish pathological from normal variance in limb praxis performance. We describe a theoretically motivated, comprehensive assessment battery for limb apraxia and present control comparison scores for 16 older healthy normal(More)
There are few investigations comparing practice schedules in speech motor learning, despite certain schedules being recommended for the clinical treatment of speech motor disorders. This study compared effects of random, blocked and mixed practice on tongue twister accuracy in unimpaired speakers. We hypothesized that blocked practice would benefit(More)
Models of connected speech production in Mandarin Chinese must specify how lexical tone, speech segments, and phrase-level prosody are integrated in speech production. This study used tongue twisters to test predictions of the two different models of word form encoding. Tongue twisters were constructed from 5 sets of characters that rotated pairs of initial(More)
