Theories of coordination

Question 1

What is open loop control (Keele, 1968)?

Answer 1

• once the brain sends a command to the muscle, there is no further interaction between the two.
• Entire movement organised by the brain and no other info (feedback) is needed to control movement.

Question 2

What is Closed loop control (Adams 1971)?

Answer 2

• Memory trace interprets sensory info and plan the motor program.
• motor program (Effector or perceptual trace) carries carries out action.
• possible to adapt movement if needed due to temporary feedback which is compared to the memory trace.

Question 3

What is the difference between open loop and closed loop control?

Answer 3

the way sensory feedback is used to alter movement/technique.

Question 4

What is the Schema Theory (Schmidt, 1975)

Answer 4

we store a series of general motor programs that group together similar movements
