Attention Flashcards
Inattentional blindness
Failure to see visible and otherwise salient events when paying attention to something else
Information filter
Filter out irrelevant information to task goals
Via parietal lobe
Cocktail party effect
Attention switches when hear name
Two messages presented to each ear simultaneously—> mix together stimuli
=creation of meaning
Spatial attention
Attention is a spotlight fixated on one thing
Laberge (1983)
- items in 5 different locations across visual array
- mean response time longer when on peripheral
- more attentional resources to the centre
Exogenous cue
Appear in periphery, appearance of something
- valid- same location of stimuli and flash
- invalid- different location of stimuli and flash
Endogenous cue
Symbolic cue in centre of vision, process cue and shift attention after
- valid- arrow has rightly moved attention to stimuli
- invalid- arrow has directed attention to wrong stimuli
Inhibition of return
Facilitates attention switching
Stops attention getting stuck on particular features
Global / local processing
Global- processing a visual stimulus holistically
Local- processing local features- details and parts
Stroop task
Integration of stimulus features
Conflict condition
Congruent condition
Difficult to suppress automatic response to read
Visual search
Parallel search:
- find the “T”
- find the red letter
Conjunctive search—> serial search:
-find the red T
Measure response times and HIT rate
Feature integration
Perception shifts from initial local configuration of four dot pairs, each rotating
To global perception of large translating squares with dots at corner
Change in perceived speed
Right posterior parietal cortex
The Simon Effect
Information presented to left ear about information on our left
More easily processed than if information was on right
Consistent representations are easier to compute
Incompatibilities tax attention
