| Question | Answer |
| Bottleneck Theory of Attention | We have a limited serial processing capacity for information Non-attended info is processed at a low level Now considered inflexible and rejected |
| Automatic vs Controlled Processing Theory of Attention | Automatic 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 |
| Automatic Processing is used for | Familiar tasks, or those with perceptual uniqueness (pop-out effect) |
| Pop-Out effect | Automatic 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) |
| Controlled Processing is used for | unfamiliar tasks, or those without perceptual uniqueness |
| What are the two attentional processes? | 1) Selective (focused) attention 2) Divided attention |
| Selective Attention | We 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) |
| Divided Attention | Simultaneously paying attention to two or more messages or tasks |
| Change Blindness | Change 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. |
| Innatentional Blindness | When you are focused on a scene but fail to notice an alien object that suddenly appears Shows evidence for selective attention |
| What are the two regions of the cortex responsible for attention networks? | 1) The posterior attention network 2) The anterior attention network |
| Posterior Attention Network | Located in parietal lobe Responsible for visual searching Activates when people pay attention to spatial locations |
| Anterior Attention Network | Located in frontal lobe Responsible for inhibiting responses to stimuli (stroop task) Active for top-down control of attention |
