Attention Flashcards
1
Q
Definition of attention:
A
- Processes that enable a person to recruit resources for processing selected aspects of the incoming sensory information more fully than non-selected aspects.
- Includes allocating resources to relevant aspects of the environment
2
Q
What influences the use of early or late selection
A
What the task involves and its instructions
3
Q
What can distractor interference cause?
A
- Slowed reaction times to targets,
- Reduced accuracy to targets
- Changes to trajectories in movements to targets
4
Q
In the H/E task, what is the conclusion?
A
Irrelevant information slows responses to the target, particularly when the opposite response needs to be inhibited.
5
Q
What are the three components of shifting attention?
A
- Disengagement, 2. Movement/shifting, 3. Engagement.
6
Q
What are the neural substrates of the three components of shifting attention?
A
- Disengagement - damage to parietal lobe results in loss of disengagement.
- Movement/shifting - damage to the superior colliculus impedes movement, eye movements also compromised.
- Engagement - damage to regions of the thalamus compromises this function.

Q
What is change blindness?
A
When a small change in visual display is not noticed
