relationships between information
Spreading Activation

Priming
cues that stimulate the retrieval of new information
Top-Down Processing
the internal shift in attention to stimuli
Bottom Up Processing
attention directed unconsciously to a stimuli, Starts with information from senses & moves up to broad
Attentive Processing
when stimuli is similar enough that it doesn’t draw attention

when stimuli differs enough that it stands out (grabs your attention) (pre→differs)
Speed Accuracy Tradeoff
rather be fast but less accurate or accurate but slower
