ACT-R
SNIF-ACT
Information foraging theory: derived from food foraging theory called optimal foraging theory - helps biologists understand the factors determining an animal's food preference and feeding strategies, scent determined the utility
application: How do people search for information? they rely on cues (scents) in their information environment. Human users estimate how much useful information they are likely to get on a given path, and after seeking information compare the actual outcome with their predictions. When the information scent stops getting stronger (i.e., when users no longer expect to find useful additional information), the users move to a different information source

creativity
defocused attention
if you are capable of focusing on several ideas at the same time you are more likely to come up with a creative idea = less focused/defocused attention

Campbell Selectionist Theory of Creativity - blind variation and selective retention: we think of something creatice just by chance analogy
analogy with biological evolution: random variants that are fit are retained, those that are unfit are not retained implementation of the analogy
