| 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. |

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
|
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
|
Definition
| the amount of force put out can change. short or long pass in soccer. |
|
|
Term
|
Definition
| nerves in the body that detect where the body is regarding to time amd space. |
|
|
Term
|
Definition
| nerves that detect external stimuli, such as pressure, temperature, etc. |
|
|
Term
|
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
|
Definition
| study of how organisms acquire and refine motor skills. |
|
|
Term
|
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 |
