Selective Attention
|
The processes through which you somehow slect one input and "tune out" the rest
|
Divided attention
|
Examining when and if you you can do multiple tasks at once.
|
Shadowing
|
Particpants hear a tape recording of someone speaking and must echo this speech back, word for word, while they are listening to it.
|
Attended channel
|
The one particpants are told to listen to
|
Unattended channel
|
Particpants are instructed to ignore
|
Dichotic listening
|
A task in which participants hear two simultaneoous verbal messages-one presented via headphone to the left ear, a second presented to the right ear. In typical experiments particpants are asked to pay attention to one of these inputs and urged to ignore the others.
|
Filter
|
A hypothetical mechanism that would block potential distractors from further processing.
|
Fixation target
|
A visual mark at which one points ones eyes. Used to help focus on a target.
|
Inattentional blindness
|
The failure to see caused by inattention (Mack & Rock, 1998)
|
Change blindness
|
Observer's remarkable inability to detect changes in scenes they are looking at. (Simons & Levin;1998-door thing)
|
Stimulus based priming
|
Presentation of the priming stimulus, with no role for expectations.
|
Expectation based
|
Created only when the particpant believes the prime allows a prediction of what's to come. Slower than stimulus priming.
|
Limited capacity system
|
A group of processes in which resources are limited, so that extra resources supplied to one process must be balanced by withdrawal of resources somewhere else, so that the total resoures expended do not exceed some limit.
|
Unilateral neglect syndrome
|
To ignore all inputs coming from one side of the body. Comes from brain damage to the parietal cortex.
|
Study with unilateral neglect sydrome (Searchlight beam of attention hypothesis)
|
Shows that one area seems to disengage the beam from its current focus; another area contols the movemnt of the beam to its new target; a third area serves to lock the beam into its new focus.
