Document Summary
Chapter 4 sensory contributions to skilled performance. Provides info to the processing system about the state of the environment in which one"s body exists. Inherent (or intrinsic) feedback: direct availability to the performer, natural awareness. Vision: physical structure of environment, basis for anticipation, movement of objects in environment, detection of one"s own movement with respect to environment. Important to musicians (obviously: clinicians and practitioners doing examinations and assessments, sporting skills, sound of the blade on ice, occupational settings, cues, alarms, alerts. Provides info about the state of the body itself. Info sources such as vestibular apparatus, joint receptors, muscle spindles, golgi tendon organs and cutaneous receptors. Vestibular apparatus: receptors in inner ear, movement (acceleration) and orientation of head in space with respect to gravity, posture and balance. In muscle belly, in parallel with muscle fibers: changes in length of the muscle. Golgi tendon organs: sensitive to force (tension) Cutaneous receptors: haptic sense (sense of touch)
