Cards

Term
what is a general motor program theory?
Definition
the idea that a command center, in the brain, controls movement. movements can slightly change based on parameters.
Term
what are the Invariant features of a motor program theory?
Definition
relative timing, relative force, and sequence of actions
Term
what is a dynamical systems theory?
Definition
a theory that suggests performance emerges from an ever changing relationship between the learner, task and the environment
Term
what are the 4 proprioceptors in the body?
Definition
Golgi tendon organs, muscle spindles, jont kinesthetic receptors and the vestibular apparatus.
Term
what are the parameters of a general motor program theory?
Definition
overall duration, overall force, muscle selection and movement direction.
Term
what is the vestibular apparatus?
Definition
an organ in the ear that helps proprioception, it measures gravitational, angular and linear accelerations in relation to inertial space.
Term
what are golgi tendon organs?
Definition
organs that are attached to the muscle and tendon that relay corresponding information to protect muscle and tendon from damage
Term
what are muscle spindles?
Definition
neurons on the muscle that measure how and how fast a muscle is changing in length.
Term
what are joint kinesthetic receptors?
Definition
little nerves located on synnovial joints that measure speed and direction of a joint.
Term
describe the sequence of actions.
Definition
the sequence of actions for example in writing your name or a volleyball spike, never change. i, after n, preceding c and then k.
Term
describe relative timing.
Definition
the idea that the same percentage of the time will be spent during the different components of a movement
Term
describe relative force.
Definition
the idea that the same, relative amount of force sill come from the same muscles during a movement.
Term
describe muscle selection.
Definition
during a movement, you can slightly change the muscles you use.
Term
describe movement direction.
Definition
you can change the direction that you make a movement, for example, the direction of a soccer pass.
Term
describe overall duration.
Definition
the overall time spent on a response can change, slow or fast.
Term
describe overall force.
Definition
the amount of force put out can change. short or long pass in soccer.
Term
what are proprioceptors?
Definition
nerves in the body that detect where the body is regarding to time amd space.
Term
what are exteroceptors?
Definition
nerves that detect external stimuli, such as pressure, temperature, etc.
Term
what are interoceptors?
Definition
nerves that detect the body's internal stimuli, such as hunger and sleepiness and mood.
Term
what are the four characteristics of a motor skill?
Definition

- goal oriented

- body or limb movement required

- developed through practice

- voluntary

Term
What is motor learning?
Definition
study of how organisms acquire and refine motor skills.
Term
What is motor control?
Definition
study of how organisms plan, generate, execute and regulate movement.
Term
what is motor development?
Definition
the study of how patterns change across an organimsm development.
Term
what are the two approaches of perception?
Definition
the ecological approach and the information processing model.
Term
what is the ecological approach of perception?
Definition
environment and task are interpreted in terms of affordances.
Term
what is the information processing model of perception?
Definition
humans process the information they recieve rather than just respond to stimuli.
Term
what factors influence reaction time?
Definition
stimulus-response compatibility, number of response choices, controling levels of uncertainty, anticipation, foreperiod consistency
