Skill Acquisition

Question 1

basic problems of motor skills

Answer 1

skill acquisition

serial order problem

Question 2

stages of skill acquisition

Answer 2

cognitive
associative
autonomous

Question 3

cognitive stage

Answer 3

first stage of skill acquisition
uses declarative knowledge
requires paying attention

Question 4

associative stage

Answer 4

second stage of skill acquisition
strengthen connections that lead to the desired result
get rid of actions that lead to errors
feedback is important

Question 5

autonomous stage

Answer 5

final stage of skill acquisition
the skill can be performed quickly and with less attention
less able to verbalize how one performs the action
feedback is not as important

Question 6

adaptive control of thought (ACT)

Answer 6

general model of human cognition

procedural knowledge is separate from declarative knowledge and is made of production rules

Question 7

ACT knowledge compilation

Answer 7

proceduralization: taking declarative knowledge and turning it into productions
composition: taking several productions and turning them into one production

Question 8

response chaining

Answer 8

feedback from one movement triggers the following one

Question 9

why is response chaining proven to be incorrect?

Answer 9

movement is proven to occur too quickly for feedback to have taken place

Question 10

motor program

Answer 10

representation of a plan of movement and movement sequences 
fast
doesn't require feedback 
abstract 
hierarchical 
made up of sub-programs

Question 11

Rosenbaum experiment

Answer 11

methods: subjects make movement sequences, time between responses is measured
results:
- jagged reaction time pattern is consistent with the tree-structured motor program
- executing motor programs required one response to be performed, and the next one is determined by searching through the tree

Question 12

Fitt’s Law

Answer 12

the time required to hit a target depends on the size of the target and one’s distance from it
describes aimed movements
