Lecture 18 Flashcards
How we learn, Theories of Skill Aquisition
who was the person that produced the memory drum idea
Henry and Rodgers, 1960
who was the person that produced the “motor program” idea
Keele, 1968
what is the idea of the motor program and what does it suggest
suggests that the brain is like some sort of super computer and that the motor programs are sitting there waiting for us to use
what are the 5 stages to information processing demands of movement
- input
- perception
- decision making
- execution
- feedback
what theory did Schmidt provide
schema theory
what became clear about the motor programming model when the information processing model was released
it soon became apparent that motor programs for each skill was unlikely
what does GMP mean
generalised motor programs
what are the invariant features of generalised motor programs
- sequence of actions
- relative timing
- relative force
what are the parameters of generalised motor programs
- muscle selection
- overall duration
- overall force
what has more recent neurophysiological research shown about the brain
research linked different brain areas to specific functions
what is the main characteristic of the cognitive approach models (about the brain and how thats linked to the body)
top down
- body is controlled by the brain
actions are determined by what factors
both internal (goals, prior experiences and capabilities) and external (what is available in the environment)
what approach uses direct perception
ecological approach
a study by Kelso (1981, 1984) on in phase and antiphase finger movements linking to ecological dynamics suggested what about movement patterns
movement patterns aren’t always what our brains want us to do, sometimes they are spontaneous
using bench press as an example what is meant by attractor in dynamic systems jargon
bench pressing with good form
using bench press as an example what is meant by control parameter in dynamic systems jargon
increasing the amount of weight used in bench press
using bench press as an example what is meant by rate limiter in dynamic systems jargon
increasing the weight beyond that capability of the exerciser
using bench press as an example what is meant by phase shift in dynamic systems jargon
change in the correct form caused by too much weight used in the bench press
how is the constraint model different to the hierarchal model
- not just top down approach
- self organises from organismic, task and environmental constraints interacting together
what is the main feature of the ecological dynamics approach
bottom up
in the ecological dynamics approach it is said that coordination emerges from what
many interacting constraints
