= understanding details first then putting them together to get the entire stimulus
* relies on pattern recognition and template matching
ex. beginner reader sounding out words then putting them together
\ Cuh-Ah-Tuh = CAT

Feature Detectors
Neurons in brain that responds to very specific lines, angles, arcs, etc.

New cards
Template
= mental blueprint held in memory
* to recognize incoming stimuli, you compare it to template in your memory until it matches
4
New cards
Top-Down Processing
= understanding the big picture first then filling in the gaps with details
* uses prior knowledge to help identifiy stimulus (expectations, beliefs, etc.)
\ ex. reading and not noticing a typo because you already fixed it in your head due to expectations of the word should have fitting in with the rest of the sentence

New cards
Gestalt Theory
= “the whole is more than the sum of the parts”
* top down processes * brain groups stimuli together into predictable patterns
6
New cards
Proximity
= the closer 2 figures are, the more we see them as part of the same object
7
New cards
Similarity
= tendency to group figures according to how closely they resemble each other
\ ex. a rectangle with different colored/patterned sides is perceived as 2 pieces
8
New cards
Good Continuation
= tendency to interpret intersecting lines as continuous
\ ex. we think 2 cats are 1 continuous cat despite knowing cat is unlikely to be so long
9
New cards
Closure
= tendency to complete figures even w/gaps
10
New cards
Illusory Contours
= tendency to perceive contours when they do not exist
11
New cards
Common Movement
= tendency to see a group moving as one large object
ex. schools of fish
12
New cards
Figure-Ground
= tendency to confuse figure w/background
ex. face/vase reversible figures
13
New cards
Automatic Processing
= doesn’t require much effort, notice stimuli w/o paying attention
ex. reading billboard signs even if you don’t want to
14
New cards
Controlled Processing
= to successfully process/do a task, need to consciously pay attention
\ ex. “Where’s Waldo” as opposed to billboard reading
