3. Humans Flashcards
What is the principle to divide tasks between Human and machine?
Augment the human intellect and capacities
Let both do what they are good at
Consider the joint performance of humans and computers
Describe the Model Human Processor.
Input/Output
Subsystems Perceptual, Cognitive, Motor Processor
Memory (LTM, Working Memory), Stores
Describe the Human Information Processing.
Input/stimulus, encoding, comparing, respond selection, respond execution, output/respond
With attention, memory
What is the Multi-Store Model?
Describe the parts
Sensory Memory: sensory information, high capacity, short duration, filtering
STM: symbolic information, less capacity grouping chunks 7+/-2, medium duration, less processing power
LTM: episodical/semantic information, high capacity, relative permanent duration (depends on intensity and quality of memorizing), slow access
Describe Wickens 4-Dimensional Multiple Resource Model and its use.
The four important dimensions explain the variance in time-sharing performance, not two at the same time Processing stages (Perception, Cognition, Responding) Perceptual modalities (Visual, Auditory) Visual channels (Focal, Ambient) Processing codes (Spatial, Verbal)
What is the Stroop Effect?
3 groups of 6 words in different color
Say color names of words as fast as you can
The last take the longest because on interferences (Link to different chunks in LTM, strong clues in working memory)
Name the Gestalt Laws?
Law of Similarity Law of Proximity Law of Continuity Law of Pragnanz Law of Closure Law of Common Fate Law of Symmetry
What is Change Blindness?
Phenomenon in visual perception
Large changes in a scene aren’t noticed
Happens when there is a short distraction (mud splashes, brief flicker, cover box)
In the visual perception what is important for reading?
Visual, pattern perceived, Decoded using internal representation of language, Interpreted using knowledge of syntax, semantics, pragmatics
Saccades and fixations
What could be the effect of emotions?
Affect = biological respond to physical stimuli Positive = creativity Negative = narrows thinking
What is the Affordance Theory?
Affordance is the perceived possibility of actions
Perceived Affordance includes experience of an individual
What is the Lie Factor?
In the data visualization
LF = size of effect shown in graphic/size of effect in data
Size of effect =abs(second value - first value)/first value
