Week 7 Cognition and Design
Humans are Informavores
Traditionally human survival depends on ability to predict and to plan
-humans seek, gather, share, and consume information in order to adapt
-human brain evolved for perceptually rich but information-sparse environments
-estimate our mental models of a situation can have about 6 elements, 2 of which are active
-the rest is background (remember change blindness)
Unfortunately for our brains, the information environment has changed quite a bit…
New experiences for old brains
Transistor density doubles every 24 months
Disk density doubles every 12 months
Brain volume doubles every 3 x10^7 months
Intuitions about architectural processing are inaccurate = “metacognitive gap”
