Human Information Processing Flashcards
Three Stage Model
Stimulus -> [(Perceptual Stage) -> (Cognition Stage) -> (Action Stage)] -> Response
[happens inside, cant see it]
Perceptual Stage
Gets information from the sensory organs about stimuli
involved in detection, discrimination, and identification
Cognition Stage
Identifies or classifies the stimulus
Starts to form a response
Action Stage
Overt response is planned and preformed (if need)
Sensory Memory
Gets information from the senses about stimuli
Passes information to working memory by attention
Iconic memory
for visual stimuli
“Eye”conic
Echoic memory
for auditory stimuli
Sound echos
Haptic memory
for touch
feel the Hat on your head?
Working Memory
A temporary memory system to do and order complicated tasks
Fragile and contents must be maintained (rehearsal)
Passes information to Long-term memory by encoding
Components:
the Phonological loop and the Visuo-spatial sketchpad
Phonological loop
stores the sound of language
You hear someone speak on the “Phone”
Visuo-spatial sketchpad
stores visual and spatial information
draws info out in your head
Data-Limited Processing
Info is too “low quality” (degraded or imperfect)
Resource-Limited Processing
system is not strong enough do the task efficiently
Asking to much of the system
Structurally Limited Processing
Cant do several tasks at once
Detectability
the absolute limits of the systems to detect that a stimulus is present
