stages of skill acquisition
|
cognitive, associative, autonomous
|
|
|
cognitive stage
|
declarative knowledge, requires attention.. the best teacher may not be the most skillful but reahter someone who knows how to describe the cognitive stage well
|
|
|
associative stage
|
strengthens connections that lead to desired result... feedback important, see which actions lead to desired result and get red if actions that lead to errors
|
|
|
autonomous stage
|
fast, executed with less attention/consciousness, less verbalization and feedback less important, need for consistent practice
|
|
|
ACT
|
adaptive control of thought
|
|
|
ACT
|
procedural knowledge... made of production rules... if-then statements
|
|
|
ACT - knowledge compilation
|
prodecuralization, composition
|
|
|
prodecuralization
|
take devlarative knowledge and turn into productions
|
|
|
composition
|
take several productions and join them together into one
|
|
|
response chaining
|
feedback from one movement triggers the next one... it is incorrect, because movements occur too quickly
|
|
|
motor program
|
representation of the plan for movement and movement sequences, fast and doesnt require feedback..abstract and heirarchical..abstract high level and specific low level
|
|
|
heirarchical motor program
|
rosenbaum experiment, measure time between responses, make movement sequences
|
|
|
evidence for subprograms
|
for longer sequences, more subprograms must be rerieved before bring sent to the muscles
|
|
|
PDP...
|
emphasizes parallel processes, since serial processing by neurons would be too slow...concepts are in the petterns of connections, not any individual node
|
|
|
ACT-R...
|
concepts represented by propositions etc... each node represents a concept
|
|
|
types of neurons and connections
|
inactive, excitatory, and inhibitory
|
|
|
inactive neurons
|
not excited, does not directly influence others
|
|
|
excitatory neurons
|
when excited, stimulate other neurons
|
|
|
inhibitory neurons
|
when excited, inhibits stimulation of other neurons
|
|
|
how PDP says we acquire skills...
|
learning/skill acquisition... using connections increases their strength... neurons that fire together, wire together
|
|
|
Fitts's Law
|
size of target
distance from target |
|
|
defying fitts's law
|
no penalty for size of target
|
|
|
obeying fitts's law
|
microsoft places menus on windows
|
|
|
skill acquisition
|
how does practice turn declarative knowledge into procedural knowledge... through ACT-R and PDP
|
|
|
serial order problem...
|
how do different parts of a skill get organized into a sequence? motors programs and fitts's law
|
