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not used b/c it's outdated and b/c you have information processing theory which is more specific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
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-
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
