Question Answer
UK Transport 'looked but did not see' 3rd
Wickens and Long Pilot simulation
William James"Everyone knows what attention is" - everyone knows what it subjectively feels like
Helmholtz (1894) Covert attention - could report an array of letters without moving eyes
Cherry (1953)Dichotic listening
Treisman and Gelade'tap' when heard 'tap' - could do so reliably
BroadbentFilter model - bottle neck
Moray When you heard your own name in ignored stream you become aware of it
Carteen and WoodPaired words with shocks - when you heard those words, you still responded
Treisman Filter-attenuation model
Treisman'Moving spotlight'
PosnerAttention-cuing paradigm - stimuli within spotlight reach awareness
Hawkins et al.Attention increases reaction time and improves perception
Eriksen and Ericksen Zoom lens - flanker effects - 1 deg. visual angle
Moran and DesimoreV4 cells respond only when paying attention
Rees et al.May attention to dots / moving stimuli in corner - V5 only responds when attention focused on moving stimuli
Eglin Bilateral neglect is a problem with attention not perception - eye movements confined to ipsliateral side of space
Bisiachi Luzatti Ignore contralateral size of remembered scenes
Treisman and Gelade Visual search paradigm = parallel search / serial search = Feature Integration Theory - attention glues features together by applying spotlight serially
Egly et al.Cuing paradigm - attention selects objects
Richard et al.Flanker effects - if flankers on a different object, then affect goes away
Driver and Halligan Baliant's syndrome - more likely to detect differences when standing on R of object than on the L, but being the L of space had no effect.
Mattingley, Davis and DriverExtinction - single objects can be detected in each side of space, but when 2 presented bilaterally, we select R hand object
Pylyshyn and StormMultiple-object tracking tasks do not make sense from a spotlight point of view
Nakayama and SilvermanLate selection theory - pop out of shape and depth
MacCleod et al.Late selection theory - moving X's and O's
Shrifin and Gardener Late selection theory - all items viewed and processed, and then one is selected with the purpose of controlling behaviour
Duncan (1980)Consensus view - multiple levels of selection - 4 objects initial selected for higher processing and then one of these is selected to control behaviour
