what is the origin of the motor programme?
many researchers beleived motor commands are represented and stored in the CNS.
one loop control - motor programme (Keele)
Movement executive - movement effectors. In the middle movement commands that go from movement execitive to movement effectors
closed loop control
same as one loop but has feedback coming from movement effectors back. In closed-loop theory, early learners develop representations of the expected movement by using outcome-related feedback (knowledge of results) to gauge their progress.
information processing demands of movement order
Input - perception - decision making - execution - feedback.
indrcet perception
the idea that perception requires at least three components; the environment, the organism, and at least one other component that mediates between the organism and the environment.
schema theory
schmidt (1975) that there cannot be motor programes for each skill. so he saud that key movement parameters are modified for generalised motor programmes (GMP)
GMP
GMPs provide a blueprint for producing movements and can be modified or adapted to meet the demands of different tasks. a sequence of actions, with relative timing and relative force.
neurocomputational theories
researches linking different brain regions to specific functions. filed of robotics highlight how messy and complex the environments are (for their coding)
ecological psychology
movement is much more complex than a simple input-output relay of information from the brain to the other systems. actions are determined by many factors internal and external.
what is the difference between external and internal factors
internal - goals, prior experineces and capabilities of the indvidual
external - what is available in the environment.
Direct perception
we directly interpert things with no intermediate stages between perception and action.
three categories human movement - self-organisation via constraint
organismic, environment and task.
