Chapter 20: Perceptual Motor Development PED 383: Adapted Physical Education Dr. Johnson
Sensory input Receiving energy forms from the environment and from within the body itself as sensory stimuli and processing the information for integration into the CNS. Incoming messages Sensory integration Integrating comparing and storing short or long term memories Output and feedback Movements occur as a result of decisions from the CNS. The actual movement response – jump, run, etc As this happens, information is sent back in as feedback Overview
Perception Monitoring and interpreting of sensory information or knowledge resulting from the interaction between sensory and CNS processes Perceptual motor development Enhancing the ability to integrate sensory stimuli arising from or relating to observable movement responses Sensorimotor activity Motor responses to sensory output Does not require cognitive ability Affordances Actions exerted on the environment Ecological approach Perception is specific to each person and that the environment is perceived directly in terms of its usefulness for the perceiver Terminology
Hitting a baseball when pitched Understanding tracking Messages to the CNS on information input Decision based on input information Information added based on result Hit Strike Should have not swung Examples
Motor output is impacted by deficits in several areas Visual Auditory Vestibular, kinesthetic or tactual Mental or affective Each have different responses based on level of disability Deficits
Sensory Stimulation Associate senses with movements Not dependent on cognitive ability Overlap in sensorimotor activities How to overcome deficits or prevent them
Ability to interpret sensations through the skin (feel) Types Proprioception Feelings form inside the body Kinesthetic Perception Awareness and memory of planned movement and position Body awareness(feeling a movement correctly) Laterality Balance Relation between the body and gravitational pull (equilibrium) Tactile Perception
Body awareness Ability to derive meaning from the body Body Schema Information supplied through activity of the body Body image Feelings one has about their own body How it functions, not how it looks Body concept Knowledge one has about their own body Body parts Kinesthetic perception
Laterality Knowing both sides of the body Verticality Knowing the up and down sides of the body Kinesthetic perception
Visual Figure-ground Ability to distinguish the main figure or target from the background or to give meaning to form(s) Spatial Locating objects in space Egocentric – self in space – not touching hoop Objective – others – complete a pass when guarded Perceptual constancy Recognizing objects despite changes in presentation Football – always the same size, color, shape Visual-motor coordination Coordinate vision with movements Development Include activities that are specific for your type of need (listed above) Visual
Auditory acuity and perception How we hear Auditory figure-ground Distinguish and attend to relevant auditory stimuli against a background of general auditory stimuli Auditory discrimination Distinguish among frequencies, qualities and amplitudes of sound Sound localization Determining the source or location of a sound Smoke alarm when batteries need to be replaced Temporal auditory perception Recognize and discriminate among variations of auditory stimuli presented in time (tempo) Auditory-motor coordination Coordinate auditory stimuli with body movements Development Include activities that are specific for your type of need (listed above) Auditory
