Lecture 4B attention Flashcards
(28 cards)
what do we need attention for?
- selecting info we need
- blocking out useless information
divided attention
- multiple tasks
- helped by automatization
early selection
= Broadbent’s filter theory
- selection between primary sensation and meaning
Cocktail party effect
- you hear your name even in the unattended track
dear aunt jane effect
- you follow the meaning
- can switch between two audio tracks
leaky filter model
= Treisman’s attention theory
- task dependent filter
- always leaky
inattentional blindness
- you dont perceive something because you dont attent to it
fronto-parietal network
- for all conscious processes
- involved in attention
spatial shadowing
- unattendence to a prominent object
- due to focus on other object
late filter theory
- Deutch and Deutch
sequential
- tasks done by switich between them
Stroop taks
- reading a colour name printed in a different colour
- or vice versa
- > only colour recognition is a problem, therefor reading is an automatic process
constant mapping
- a target is never the distractor
- enables automatization
varied mapping
- target can be used as a distractor
unlearning
- former target becomes distractor
- way harder than learning
feature-based attention
- attention to properties of objects
lacation based-attention
- space attention
internal attention
- attention to your own mind
endogeneous
- goal-driven
- top-down
exogeneous
- bottom-up
- stimulus-driven
spatial cueing task
- press a button when light appears in one of two spots
- indicated by arrows, i.e. cues
cues
- must be informative to have an effect
- invalid, valid or neutral
covert attention
- without eye movements
- used in spatial cueing tasks
overt attention
- with eye movements
