1Inattentional blindness
- When fixating on one feature, easy to miss other things
- Inability to notice things change with quick visual flashes
2Evidence that attention works at the level of objects
simultagnosia: if they are combined as one object, they are able to notice theres two different colours, otherwise they can't differentiate, can only see one
3One example of structural processing
- demand
- capacity
- automaticity
- bottlenecks
4Support for early bottle neck:
- Mackay, river-bank
- dichotomous listening task
- broadson filter theory
- Perceptual load theory
5Describe the key results of the perceptual load experiment
Higher load led to slower reaction times but less effect of the distractors. This is because less attention to slip
6Describe the key results of the working memory perceptual load (laviey)
Higher load led to more effect of distractors, less control of attention
7Describe Kahnmens capacity theory
Limited cognitive resources available for each task, demanding tasks make it less likely you can focus on something else
8Evidence for the theory you can improve capacity
By automating certain tasks they take up less cognitive resources and thus improve ability to do more than one thing at a time
