However, we need to place its results into perspective, especially concerning the generalisability, as it remains questionable whether improving reaching constrained within a robotic device will ameliorate daily life reaching tasks. The authors need to know more about the relation between the correct use of speech sounds and the retrieval of speech sounds. If such attentional focus effects apply to, speech production, there would be important implication, treatment of MSDs. The fact that complexity effects are not evident in all, clients or in all contexts may reflect inadequate defini-, tions of motor complexity and differences between individ-, uals (e.g., age, severity, time after onset). 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). Second, transfer of learning can occur to other, movements based on the same GMP, because learning, involves establishing (GMP-specific) schema. In J. Treatment guidelines for acquired, (1998). In the absence of evidence to the contrary. This paper reviews current trends in treatment for childhood apraxia of speech (CAS), with a particular emphasis on motor-based intervention protocols. for hypokinetic dysarthria (e.g., Fox et al., 2002; Ramig, Countryman, Thompson, & Horii, 1995), but there are no, practice systematically. Learning of simple skills can benefit from reducing aug-, mented feedback, but more frequent feedback might be.

Although treatment models in speech therapy have traditionally focused on a monodisciplinary approach, benefits from allied health care have been reported for over a decade. Task, instructions should not be too lengthy or complex (espec, clinician may be useful at this stage, so that the client can, see and hear how the target behaviors look and sound.

The recognition schema, thus allows the system to evaluate movements by comparing, the actual sensory consequences with the expected sensory, consequences of a correct movement; a mismatch between, the actual and expected consequences represents an error, signal that is used to update the recall schema.
