- 1Bottleneck Theory of AttentionWe have a limited serial processing capacity for information
Non-attended info is processed at a low level
Now considered inflexible and rejected - 2Automatic vs Controlled Processing Theory of AttentionAutomatic processing is parallel; two or more items can be attended to at once
Controlled processing is serial; one thing can be focused on at a time - 3Automatic Processing is used forFamiliar tasks, or those with perceptual uniqueness (pop-out effect)
- 4Pop-Out effectAutomatic processes don't require attention
Distinctive features "pop-out" and draw our notice (when we searched for the blue x among red x and o figures) - 5Controlled Processing is used forunfamiliar tasks, or those without perceptual uniqueness
- 6What are the two attentional processes?1) Selective (focused) attention
2) Divided attention - 7Selective AttentionWe can focus and choose what we want to pay attention to
We are not perfect at tuning all other information out though (dichotic listening task, cocktail party effect, stroop effect) - 8Divided AttentionSimultaneously paying attention to two or more messages or tasks
- 9Change BlindnessChange blindness occurs when a change in a visual stimulus is introduced and the observer does not notice it. For example, observers often fail to notice major differences introduced into an image while it flickers off and on again.
- 10Innatentional BlindnessWhen you are focused on a scene but fail to notice an alien object that suddenly appears
Shows evidence for selective attention - 11What are the two regions of the cortex responsible for attention networks?1) The posterior attention network
2) The anterior attention network - 12Posterior Attention NetworkLocated in parietal lobe
Responsible for visual searching
Activates when people pay attention to spatial locations - 13Anterior Attention NetworkLocated in frontal lobe
Responsible for inhibiting responses to stimuli (stroop task)
Active for top-down control of attention
