what are the 3 stages of information processing
|
Stimulus ID/ perception
Response selection Response Programming |
|
Example of Stimulus ID/ perception
|
Color contrast: black hockey puck on white out, (the standout value is greater)
|
|
Example of Response selection
|
Baseball pitch:if you don't know what pitch is coming your chances of hitting are less. (more uncertainty)
|
|
Example of Response programming
|
more complex the movement the greater time required for task: a fast pass compared to a slow pass.
|
|
Serial Processing and what stage it occurs
|
Serial- one choice at a time ...occurs in 2nd stage
|
|
Parellel processing and what stage is occurs in
|
Parellel-multiple information coming in...1st and 3rd stage.
|
|
what is the black box analogy and why is it not used.
|
input -> human -> output
not used b/c it's outdated and b/c you have information processing theory which is more specific |
|
what is Hick's Law, and what stage does it occur
|
relatoinship b/t number of movement choices and time needed to prepare a response, where the higher the degree of uncertainty, the longer the time needed to decide response...2nd stage
|
|
Hick's Law and bit formula
0 bits=? choices 1 bits=? choices 2 bits=? choices |
1
2 4 choices double as bit increases by 1 |
|
Increase/decrease of stimulus ID stage:
|
increase: white hockey puck on white ice
decrease: black puck on white ice |
|
increase/decrease of response selection:
|
increase: don't know what pitch is coming
decrease: know what pitch is coming |
|
increase/decrease o f response programming:
|
increase: full bat swing
decrease: choking up on bat to make swing shorter |
|
what are the three types of memory:
|
Sensory register
short-term memory long term |
|
ways to increase memory:
ways to decrease memory: |
- chunking, add meaning
- distraction |
|
what is serial recall?
|
recalling in exact order
ex. social security number |
|
What is free recall?
|
recalling in no specific order
ex just saying the numbers in aany order |
|
what are the 3 systems for long term memory and their description:
|
episodic:personal experiances associated with time context
semantic:general knowledge associated with experiances not associated with time procedural:info on how something is done (skills or actions) |
|
what's declarative knowledge?
and what system of memory does it relate to? |
knowledge that can be described-
episodic and semantic |
|
what is procedural knowledge and what system of memory does it relate?
|
knowledge that usually can't be described-
procedural |
|
What is perceptual narrowing?
|
narrowing of attentional focus with increasing levels of arousal
|
|
Give a positive and negative example of perceptual narrowing:
|
positive: Powerlifter; when you want to just focus on one stimuli
negative: Quarterback; when you want to focus on many stimuli |
|
define Attention:
|
never clearly defined, implies withdrawl from something to focus on others
|
|
How can attention as arousal be mearsured?
|
- heart rate varibility
- clammy skin - pupil dialation |
