Human Information Processing Flashcards
Three Stage Model
Stimulus -> Perception -> Cognition -> Action -> Response
Memory Coding
Sensory Memory -> Working Memory -> Long-term Memory
Phonological Loop
Stores sound of language in working memory
Visuo-spatial sketchpad
Stores visual and spatial information in working memory
Data-Limited Processing
Information is not presented long enough or clearly enough
Resource-Limited Processing
Not enough memory “power” to perform task
Structurally Limited Processing
Inability for the structure of a system to perform several operations at once
Absolute Threshold
Smallest amount of intensity needed for a person to notice a stimulus
Difference Threshold
Smallest amount of difference needed for a person to perceive two stimuli as different
Psychophysical Scaline
Scales of psychological quantities that can be mapped to physical scales
Stevens’ Law
S = aI^n (S=sensory experience, I=physical intensity, n=variable sensory exponent)
Simple Reaction Time
A single response is made after action occurs
Choice Reaction Time
More than one response can be made and the correct response depends on the stimulus
