Attention: Measures Flashcards
Give 3 reasons why attention is important
- Negative outcomes when it fails (e.g. while driving)
- Applied contexts (e.g. advertising)
- Clinical contexts (e.g. ADHD)
What 2 theories are proposed for attention limitations?
- Limited capacity resource
- Processing bottleneck
What are the 4 types of attention?
- Selective attention
- Sustained attention
- Divided attention
- Attention to different sensory modalities
How can we study overt visual attention?
Tracking eye movements
What are the methods of studying covert attention?
- Reaction time experiments
- Error rates
- Self-report
- Neuroimaging
What is the assumption of reaction-time experiments?
Attention takes time to move around
What are the 4 types of reaction-time experiments?
- Spatial cuing
- Visual search
- Distractor effects
- Attentional capture
Explain the spatial cuing paradigm
- Responses are typically slower following invalid cues, suggesting spatial attention has moved to the cued location
- Works with endogenous and exogenous cues; covert spatial attention can be voluntary and involuntary
Explain the visual search paradigm
Increasing non-targets:
- no effect on RT if target stands out
- slower RT if target is a conjunction
= serial search is required
Explain the distractor effects paradigm
- Assume attention has been distracted by stimulus if it slows RT when irrelevant
- Responses slower when distractors incongruent
- Effect also observed in spatially separated distractors
Explain the attentional capture paradigm
- Assume attention has been captured by stimulus if slows RT when irrelevant or speeds RT when target
- Colour singleton non-target slows search RT
- Colour singleton target speeds up search RT
What task is used in error rates studies?
Sustained attention to response task
What are error rates and self-report measures used for?
- testing effects of attention on awareness
- mind-wandering
What brain regions selectively respond to specific stimulus categories?
- Fusiform Face Area (FFA)
- Parahippocampal Place Area (HPA)
