This article provides an overview of investigations of treatments for acquired apraxia of speech (AOS). Published treatment reports are summarized in tabular form to provide the reader with a resource for selecting and evaluating the empirical support for AOS treatments. The treatment summary highlights the fact that most available AOS treatments have(More)
The effects of two cueing treatments, Phonological Cueing Treatment (PCT) and Semantic Cueing Treatment (SCT), were examined with three chronic speakers with aphasia. The effects of treatment on action naming were measured with the use of single-subject experimental designs. The participants had received PCT and SCT to improve object naming in a previous(More)
This investigation was designed to examine the acquisition, generalization, and maintenance effects of a treatment for sound errors in speakers with co-occurring apraxia of speech and aphasia. Three speakers with chronic apraxia of speech and aphasia were studied in the context of a multiple baseline design across speakers and behaviors. Treatment combined(More)
This investigation examined the effects of a semantic feature training procedure on retrieval of action names in a participant with anomic aphasia. Treatment was applied sequentially across two sets of action names in the context of a multiple baseline design across behaviors. Treatment effects were evaluated in terms of naming of trained and untrained(More)
The stimulus and response generalization effects of training wh-interrogative production were examined in 4 agrammatic Broca's aphasic subjects using a multiple baseline design across behaviors and subjects. Throughout treatment, response generalization to untrained questions and stimulus generalization to several nontraining conditions were assessed.(More)
BACKGROUND: This manuscript reports the initial phase of testing for a novel, "Contextual constraint" treatment, designed to stimulate inefficient language comprehension processes in adults with right hemisphere brain damage (RHD). Two versions of treatment were developed to target two normal comprehension processes that have broad relevance for discourse(More)
BACKGROUND: This manuscript reports generalization effects of Contextual Constraint Treatment for an adult with right hemisphere brain damage (RHD). Contextual Constraint Treatment is designed to stimulate inefficient language comprehension processes implicitly, by providing linguistic context to prime, or constrain, the intended interpretations of(More)
Coarse coding is the activation of broad semantic fields that can include multiple word meanings and a variety of features, including those peripheral to a word's core meaning. It is a partially domain-general process related to general discourse comprehension and contributes to both literal and non-literal language processing. Adults with damage to the(More)
PURPOSE The authors designed this investigation to extend the development of a treatment for acquired apraxia of speech (AOS)--sound production treatment (SPT)--by examining the effects of 2 treatment intensities and 2 schedules of practice. METHOD The authors used a multiple baseline design across participants and behaviors with 4 speakers with chronic(More)
