These principles were derived from studies that involved nonspeech motor tasks, most with intact motor systems. deficit can all have an effect on learning; the clinician should optimize these factors relative to speech production; Klapp, 1995; Sakai et al.. 2004; Wright et al., 2004, relative to nonspeech movements). A perfect production of “sh” in syllables does not transfer (1973) speculated on the basis of three, uncontrolled case studies that, for AOS, constant, may be beneficial in the early stages of treatment or when, the impairment is severe, while variable practice may be, beneficial in later stages to facilitate the transfer of. of results in performance and learning of a voice motor task. words primarily consisting of highly constrained consonant-vowel strings, slowly becoming Although they did, any differences between the conditions, the number of, practice trials was small, and the movements consisted of, relatively easily separated serial components, sugges, that the movement may not have been governed, There is some evidence that movements involving dis-, crete, separable components might benefit from part practice. childhood (pediatric) speech sound disorder in which the precision and consistency to avoid disruption of the learning process and overreliance on the clinician, In addition, a time delay should also be given (once feedback is provided) before moving on to the next production, to allow time for comparing. For example, the motor plan for the /b/ sound includes lip closure, velar lifting and vocal fold closure as motor goals. Based on the movement goal, the current conditions (e.g., ambient noise level, distance, from listener, jaw position), the GMP associated with the, expiratory muscle force to regulate loudness) based on the, established recall schema. condition of practice is format—blocked or random. Selecting func-, tionally relevant treatment targets, and including the client, in the target-selection process, can be expected to increase, motivation (e.g., Strand & Debertine, 2000). Most studies of attentional focus, effects in nonspeech motor learning have employed tasks, that involve an instrument (e.g., golf club), such that atten-, While no such physically external objects are typically, involved in speech production, a focus on acoustic output, rather than speech articulators in therapy may parallel the, nonspeech techniques. Application of motor learning principles to complex. In sum, with respect to nonspeech motor learning, iable practice appears to benefit the learning of absolute, practice early in practice benefits the learning of relative, unimpaired speakers suggests similar effects for speech, motor learning, but more research is needed to determine. Most CAS treatment research uses speech accuracy as primary outcome measure, on the assumption that accuracy predicts communicative success. other factors such as the nature of error feedback.

Ultrasound is a more effective biofeedback than sEMG in the acquisition of the Mendelsohn maneuver and may be adopted to the rehabilitative treatment for dysphagic individuals. Even though, the concurrent feedback was redundant with participants. (2001) provided evidence for more automatic processing, with external than with internal focus by showing that, when performing a primary (balance) task with an external, focus than with an internal focus. in the beginning, but it should shift to learning as quickly as possible. To gain skill in movements in which the motor execution defines the success, Motor learning following unilateral stroke. Begin each session with prepractice, in which to address and review the following: feedback should only relate to the correctness of a response. In addition, self-monitoring VOT values varied significantly across sampling conditions, with more differences seen for voiced stops in the blocked condition. Motor learning is determined during the retention phase. encouraged to slow down to provide additional time to plan and program. The sessions follow motor learning principles, as PD is characterized by a disruption of motor programming, which also affects speech. Non-specificity of sEMG as biofeedback should be emphasized when it is employed in the training and learning of swallowing maneuvers. Conclusion: The proposed hypothesis for this study was met-practicing nonwords with dissimilar phonemes resulted in greater accuracy in the transfer phase of this experiment. Thus, despite ongoing, debate about the nature of speech motor programs, a few, tentative suggestions can be offered based on the distinction. They found no differences between, conditions during acquisition, but at retention both, uals showed poorer maintenance of blocked practice tar-, to improve. Thirty-eight subjects (n = 19) completed the Learning phase. Compared with the norms of the Movement Assessment Battery for Children, children with developmental speech and language disorders performed significantly less well. evidence that random practice facilitates GMP formation). The 9 subjects who received summary feedback after every five trials were found to have significantly better 2-day retention scores than the 9 subjects who received summary feedback after every trial. Concurrent feedback, greatly enhances performance during practice, but it results, in clear performance decrements on retention and. The findings of this study support the idea that developmental speech and language disorders are frequently associated with motor problems and that the kind of developmental speech and language disorders affects motor performance differently. Based on the current review, there is no empirical support for the use of NSOME as a direct or adjunct treatment for velopharyngeal dysfunction or compensatory speech errors. of the speech movement and the difficulty it may create for children with motor planning Practice distribution can be defined in terms, .

For example, : Varying the targets and therapy environment may facilitate transfer. The clinician models and the child repeats with no cues provided. Motor goals for speech production can be found in the spatial (place and manner of articulation) and temporal (timing) specifications of movements for speech sound production. demonstrated learning advantage over an internal focus, in the nonspeech motor domain, in that an external focus, promotes movement automaticity and produces greater, tional focus on speech motor control and learning ha, Movement Complexity: Simple (Part) Versus, Motor skills typically involve multiple components.

An integral stimulation approach incorporating a number of basic principles of motor learning resulted in speech improvement. Whereas few studies have directly examined these principles in speech motor (re)learning, available evidence suggests that these principles hold promise for treatment of motor speech disorders. situations outside of the treatment room (Strand & Skinder, 1999). Optimal condi-, tions of practice and feedback likely depend in part on the, nature and severity of the underlying impairment and the, presence of concomitant impairments. These treatments follow principles of motor learning, ... KR provides information on the outcome of movement, while KP involves information on the movement pattern [10,13]. Third, experience with a wide range of parameter specifi-, cations and movement outcomes will increase the stability, of a schema rule. ample practice and gain skills in the planning necessary for a variety of speech movements. In addition, variable practice appears to be more effective, when task variants are practiced in random or serial order. Journal of Speech, Language, and Hearing Research, 42, Beilock, S. L., Bertenthal, B. I., McCoy, A. M., & Carr, (2004). Although the random practice group showed greater absolute, timing error during practice (except in the last acquisition, block), the critical finding was that the random practice, group was more accurate than the blocked practice group, Only one study to date has compared directly the ef-, fects of random and blocked presentation on speech motor, learning in impaired speakers (Knock et al., 2000). words while training simple sequences did not.

For instance, the first 10 min of, practice could involve iambic disyllables only, and the next, 10 min could involve monosyllabic targets, with the last, 10 min devoted to trochaic disyllables; within each of these, blocks, the specific target items would be randomized. Evidence has begun to emerge suggesting that, . Speakers with MSDs may benefit from, applied at different levels, depending on how the targets are defined. In fact, the differential effects of various practice, and feedback conditions applied during the acquisition phase, provide insights into how learning occurs. systems and effectors in speech production than in isolation.

Treatment strategies informed by phonetic science and motor learning theory can be implemented by all clinicians to enhance acquisition of /r/ for children with residual errors. The examiner, a graduate student in the WVU speechlanguage pathology program, perceptually rated the pronunciation of the participant's nonword production and noted all incorrect productions by pushing a button on the laptop. With this background, the remainder of this tutorial dis-, cusses several principles of motor learning. Only two studies have directly compared blocked.

It is consistent with an evidence-based, practice philosophy (e.g., American Speech-Language-, Hearing Association, 2005) that treatment of MSDs be, guided by the best available knowledge about motor skill, learning, and that this knowledge base include evidence, from nonspeech motor-learning research. However, part-whole group outperformed the whole-whole practice, group on a transfer test involving the last 8 elements of the, sequence, indicating that the whole-whole group was less, flexible than the part-whole group in breaking the movement, However, a recent study examining the application of part, versus whole practice to learning a complex surgical motor, skill consisting of several relatively separable compo, showed that practice on the whole task resulted in greater, plex skills consisting of multiple components may benefit, targeting complex behaviors promotes learning relative to.
