Lecture 5- Attention Flashcards
Attention has what kind of capacity resource
Limited
Different types of attention
- Selective attention
- Sustained attention
- Divided attention
- Attention to different sensory modalities
What is selective attention
Focusing attention on certain information while ignoring other information
What is divided attention
- Multitasking
- Another way of looking at capacity limits
What is selective attention
Maintaining focused attention or vigilance
What is attention to different sensory modalities
- Sight, touch, sound, smell
- Visual has received most examination
Which response is slower, following a valid or invalid cue (e.g. arrow)
Invalid cue has slower response
Suggests spatial attention moved to cued location
Covert spatial attention can be
Voluntary and involuntary
With a reaction time experiment, if the target pops out how will increasing non-targets affect RT
It won’t
With a reaction time experiment, if the target is a conjunction, how will RT be affected
- Increase with number of non-targets
- Suggests serial search is required
It is assumed attention has been distracted by a stimulus when
It slows us down when stimulus is irrelevant
RT is typically slower when distractors are
- Incongruent compared to congruent or neutral.
- Suggests even spatially separated distractors cannot be ignored
Colour “singleton” non target affects RT how
Increases RT
Colour “singleton” target affects RT how
Reduces search RT
What measure is often used to test effects of attention on awareness
Self-report measures
