Week 3 : Attention Flashcards
What is attention?
A process to stop information overload
What is central capacity theory?
Attention is one limited pooled resource that has to be shared across tasks
What are dichotic listening tasks?
Listening to two voices at once, but only paying attention to both.
What happens to the unattended voice in a dichotic listening task?
information from the unattended voice isn’t processed as much as the attended voice
What happens if its a similar voice?
It is easier to ignore and listen to
What is attention as early selection?
Information is processed based on physical characteristics and processed partly through a selective filter
What is attention as flexible selection?
Information is attenuated and filtered after the sensory register
What is attention as a late selection model?
Information is fully analysed from sensory register to STM though there is limited capacity
What is the Posner Cueing Paradigm?
Cards will be shown to an individuals and they may have neutral, endogenous or exogenous cues. Sighted people can say attention to part of space without directly looking at it.
What is endogenous attention?
You choose to pay attention to something
What is exogenous attention?
You are forced/made to pay attention to something?
What does attention as a spotlight mean?
You can only pay attention to so much so you have to limit the amount of endogenous attention distributed to everything
What is conjunction search?
target has no unique search feature so the brain has to search harder
What is feature integration theory?
Perceptual features are processed parallel and prior to attention
What are the stages of visual search?
Rapid parallel process to identify features, slow serial process to form objects combining the features.
