Identify and Classify Motor skills
• Motor skills can be classifies using 3 schemes
o Task organization
o Motor and cognitive Element
o Level of Environment Predictability
• Allow practitioners to distinguish tasks from one another
o What tasks should be emphasized in the early and/or latter stages of motor skills
Task Organization
• Discrete Skills
o A skill that is organized such that action is usually brief and has a well-defined beginning
end
o Short action that unfold over time
o Eg. Slap shot in Hockey , Sit and Stand maneuver (one of the first tasks in clinics)
• Serial Skill
o Sequence of discrete actions
o A type of skill characterized by serial discrete actions connected together in sequence
o Often the order of the actions is critical to performance
o Eg. Playing piano, assembly line tasks
o People with strokes really suffer with these→they ca’t do it i a ode
o Clinician has to work to get them to understand importance of discrete tasks
• Continuous skills
o A skills that unfolds without a recognizable beginning or end, in an ongoing and often
repetitive fashion
o Eg. Swimming, steering a car
• For any movement it will fall along a spectrum or a continuum
Motor and Cognitive elements
• Motor skills
o Primary determinant of movement success is the quality of the movement
o High jumping and weight lifting (only for an expert)
• Cognitive skills
o Piay deteiat of success is the uality of the pefoe’s decisio akig
o Eg. Cognitive, Cooking a meal, Coach a sport
• During skill learning we generally progress from cognitive to motor
• Everything is on a continuum
Level of Environmental predictability
• Open skill
o Skill performed in an unpredictable or in motion environment, requiring the individual
to adapt their movement in response to the dynamic properties of their environment
