Integral stimulation for children requires reflection of four motor learning principles in the design of successful treatment for CAS: precursors to motor learning, conditions of practice, feedback, and effects of rate (see Strand & Skinder, 1999). cludes more general information given, for example, contrast, KP refers to the nature, or quality, of the movement, pattern. While perceptual judgments ultimately, have important ecological validity, these measures may be, fundamentally incapable of capturing fine-grained differ-, ences (Kent, 1996), including important gradual improve-, ments that may occur, or distinctions between relative and, absolute aspects of speech production.

An integral stimulation approach incorporating a number of basic principles of motor learning resulted in speech improvement. of neurologically impaired motor systems (e.g., Hanlon, In the study of motor learning, it is important to consider, the distinction between performance during, associated with practice or experience leading to relatively, permanent changes in the capability for movement, from temporary performance enhancement, and that learn-, ing cannot be directly observed but rather must be inferred. 2001, 2007; Morrisette & Gierut, 2003; Rvachew & Nowak, 2001, 2003), syntax (Thompson et al., 1998; Thompson, & Shapiro, 2007), and semantics (Kiran, 2007; Kiran &. To facilitate learning in children with According to this view, feedback, guides the individual to the correct movement, but frequent, feedback may have negative effects.

Subjects received a 20-trial retention test at ten minutes and two days following the practice session. However, it remains to be specified which aspects of speech, movements are to be considered GMPs and which aspects, can be considered parameters (Ballard et al., 2000). However, such move-, ments require much more extensive coordination across. Although obtaining long-term, follow-up measures is often impossible or impractical in, the clinical setting, one could use the first few minutes of, a treatment session to assess shorter term retention (pro-, duction of target responses without cues or feedback) and, Second, one of the most consistent findings to emerge, from the motor-learning literature is that relative (GMP) and, absolute (parameter) aspects of movements often respond, differently to practice and feedback variables. Acoustic measures, in particular can be useful, for example, to assess stre. Given that KP may, be more beneficial when the learner does not possess a reli-, able internal representation of the movement goal (Newell, et al., 1990), feedback type should be an important con-, sideration in the treatment of MSDs. Recommendations for which children may be suitable for ReST and for evidence-based practice are described. that are its foundation. (Experiment 1) studied feedback, frequency (100% vs. 60%) on the relearning of speech, Note that this distinction between internal and external focus feedback does, not correspond to the distinction between KP and KR. To test the hypothesis that Parkinson disease (PD) may be associated with deficits in the perception of loudness, 25 individuals with PD and 25 age and gender matched controls took part in three tasks. Future research using more sensitive methodologies may allow more conclusive inferences about the possible role of perceptual differences in PD hypophonia. First, there is evidence, that motor programming is disrupted in Parkinson, and ataxia (Spencer & Rogers, 2005). Because these, the primary focus is on those studies that have explicitly, compared different conditions. 3. conditions is unavailable or incorrect (Ballard & Robin, 2007; Kent & Rosenbek, 1983).

Baddeley and Longman (1978), distributed the same amount of practice on a keyboard-entry, task over 15 days (massed) or 60 days (distributed), and, found that benefits of distributed practice persisted 9 months, after training, whereas massed practice gains dissipated, shortly after training ended.

This study examined the effects of two summary feedback practice schedules on the acquisition and retention of a novel speech motor skill in a group of 18 subjects with Parkinson's disease (aged 55 to 73 years; 14 men). and speakers with AOS (Austermann Hula et al., in press). For example, the Lee Silverman Voice, Treatment (LSVT) includes large amounts of practice as, an integral component to this efficacious speech treatmen. the precursors is crucial. Such findings are positive, but distributed practice might, have enhanced outcomes even more. These findings suggest, that it is the trial-to-trial change of target rather than the, unpredictability of the upcoming trial that drives the, over blocked practice, although there is some recent evi-, dence that random practice does provide learning benefits.

At the end of 10 trials (or a single training block), summary feedback was provided by Eprime to enhance overall motor learning, ... We had two predictions regarding participants' speech motor learning. Ways to maximize precursors include motivating the child, mastery of simple repetitive movements. The frame-, work suggests that each learner has a challenge, which availability and interpretability of information are, optimal (the optimal challenge point), and that this optimal, challenge point depends on task difficulty and the skill level, of the learner.

One difficult issue is how to, define complexity of movements in general (Guadagnoli, & Lee, 2004; Wulf & Shea, 2002) and speech movements, Maas et al. support as children achieve success. As noted in the, previous section, a brief retention and transfer test can be, administered at the beginning of each treatment session in, order to track learning.
