Selective Attention
when someone pays attention to one thing at the expense of another
Dichotic Listening Task
tests ability for attention to selectively filter info by playing different info into left/right ear
Early Selection Model
attention filters message BEFORE incoming info is analyzed
Broadbent’s Filter Model (early)
sensory memory, filter, detector, memory
Aunt Jane Experiment
a story and numbers were presented at the same times in opposite ears
Intermediate Selection Model
some filtering based on its physical properties, some info still gets through
Triesman’s Attention Theory (intermediate)
Portions of signals makes it through for processing although it is reduced
Late Selective Model
selection of stimuli for final processing doesn’t occur until AFTER info has been analyzed
McKay’s Model (late)
attended ear (sentences), unattended ear (two words)
Processing Capacity
amount of info people can handle
Perceptual Load
related to the difficulty of the task
Low Load Task
use up small amount of persons processing capacity
High Load task
use up more of persons processing capacity
Load Theory Of Attention
w/ high loads there’s no resources left to process other stimuli, w/ low loads there are left over resources
Stroop Test
the word of a color written in another color
Fovea
center of retina, highest detail
Stimulus Salience
physical properties of stimulus’s (color, contrast)

Covert Attention
