Chapter 5 part 4 Flashcards
parallel processing
attending to many sense modalities simultaneously
bottom up processing
constructing a whole from its parts
top down processing
beliefs and expectations imposed on how raw stimuli is perceived
association cortex –> primary sensory cortex
Selective attention
how we focus on specific inputs
- reticular activating system
- frontal cortex
who made the filter theory o attention
broadbent
what is the filter theory of attention?
filters allows us to pay attention to important and ignore unimportant stimuli
how was the filter theory of attention tested?
-tested using the dichotic listening
theorist elaborating on broadbent’s findings
Treisman
- dichotic listening but asked to shadow
- subjects repeat what was attended/ sometimes incorporated information from unattended side if it made sense
cocktail party effect
picking out information
e.g: someone saying your name and you can hear it.
inattentional blindness
poor at detecting things in plain sight
Gestalt principles
gestalt principles and how we perceive the whole object —- governed by 6 principles
6 gestalt principles (PSCCFS)
proximity - how close they are to one another
similarity- comprise a whole more than dissimilar (circle circle, square, circle)
continuity - perceived as whole even if blocked
closure - fill in what’s missing when partial info present
figure and ground - decision of focus (central figure or background)
symmetry - figures grouped as single unit
“matching perceptual schemas”
when you don’t need the exact picture of face to recognize who it is
e.g- those whacky drawings with larger caracitures
cross modal activation
provides different perceptual experiences than either modality by itself
expectations and perception
expectations influence perceptions
- perceptual sets increase readiness to perceive stimuli in a certain way
- confirmation bias
