Attention Flashcards
What is the gaze-crowding contingent paradigm?
technique for study of attention using eye-tracking and changing of stimuli (allows study of visual input)
What happens in unconscious attentional modulation?
continuous flash suppression shows modular attentional bias (attractive picture to one eye)
What are the working definitions of attention?
Process:
selective: ability to process subset of info
sustained: ability to maintain high level of awareness
resource:
divided attention: allocation/distribution over competing inputs
what is dichotic listening (shadowing) technique?
A way to measure brain lateralization (different stimuli to each ear)
Found left-hemispheric dominance for language processing
Describe the early selection filter model
selection filter filters based on gross physical properties after sensory buffer, before limited capacity processor
How does Triesman’s attenuation model differ
attenuated (unconscious) and selective channels between selection filter and semantic analysis
why is rapid eye movement important
to overcome fact that only small area of retina capable of high res. and avoids change blindness but not inattentional blindness (misdirection in magic)
What are visual search tasks
use of parallel and serial processing, where serial (multiple shape factors) have higher set-function/time t recognise
- basic features (colours/orientaion and intensity) occurs in parallel
- feature integration bound by ‘visual glue’/attention and longer as each feature has to be processed individually to bind features
what is an attentional enhancement
valid cues facilitating RTs, cueing paradigm demonstrated covert orientating
when does automaticity occur
when performing tasks with extensive practice (reading), causing action slips
- automatic processing runs to completion once activated
what is the cocktail party effect?
ability to focus on particular stimuli while blocking others
what are the gestalt laws?
similarity, continuation, closure, proximity, figure/ground, and symmetry & order
