S2W5 - Attention Flashcards
Capacity
amount of perceptual resources available for a given task/ process
Selectivity
allocation of the perceptual resources available for a given task/ process
Covert Attention
subtle direction of attention; attention that precedes eye movement; can have multiple focal points
Overt Attention
overt direction of attention; redirection of perceptual organs towards stimuli; single focus
Early Selection
Broadbent; selectivity occurs in early processing; awareness and response occurs before semantic analysis
Late Selection
Broadbent; selectivity occurs in late processing; semantic analysis occurs before awareness and response
Endogenous cue
attention voluntarily redirected; top-down
Exogenous cue
attention involuntarily drawn to new location; bottom-up
Steps to Attention Shifting
[in order] disengagement, movement, engagement
Local Stimuli
the devil’s in the details
Global Stimuli
the bigger picture
Distributed Attention
simultaneous, parallel processing
Focussed Attention
serial processing of each ‘fixation’ of the topic
Evidence for the Spotlight Analogy
Posner cuing data; redirecting attention towards the future stimulus decreases response time, redirecting attention away from the future stimulus increases response time.
