Lecture 7 Attention Flashcards
Attention is a component of
Information processing
Overt attention
If something else in the environment catches your attention. Overtly move eyes to look at it.
Covert attention
Not paying full attention but still aware of it.
Divided attention
Paying attention to more than one thing at a time
Detection can be either
Spot light or object based attention
What is spotlight attention?
Attention like a spotlight. Shine it on a particular area.
In Object based attention you
Pay attention to a particular object not a particular area.
Which one is right? Spotlight or object attention
Both
Ppl tend to use spotlight for
Static scenes with fewer objects
When a scene is dynamic, moving objects and lots of dif focal objects ie David Attenborough then you would adopt
Object attention
Selective attention is
How much of the incoming info you’re going to process.
In early selection theory broadbent was responsible for the
Filter theory
In early selection triesman was responsible for the
Attenuation theory
Early selection filter model
Info processing occurs through stages
4 Stages of the filter system
1 sensory register
2 selective filter
3 perceptual processes
4 ST Memory
Broadbents filter model was supported by the
Dichotomy listening tasks
What is a dichotic listening task?
Headphones. 2 diff messages being spoken into each ear. Asked to repeat only one stream of info. Quizzed on how much info from unattended ear could be remembered.
Cocktail party effect is when
Filtering model not necessarily complete (something’s being linked through). Ie having a convo at a party and hearing your name across the room
Triesmans attenuation theory suggests that (leaky filter model)
Instead of blocking out stimuli, the filter weakens the strength of stimuli other than the target stimuli
Attenuation means
Weakened
Which is true early or late selection?
Both
Both early and late selection happen under different conditions. What are examples of different conditions…
Type of task
Stimuli
Task load
