ATTENTION LECTURE Flashcards
What are priors?
They fill in the gaps where information might be missing.
What is attention?
The selection of a particular sensory stimulus or mental process for further analysis.
What is the pre-attentive process of attention?
- Parallel analysis
- Determined by surrounding
- “Bottom-up”
What is attentive process of attention?
- Serial analysis
- Search light
- “Top-down”
Which brain area is mostly associated with attention?
Parietal lobe.
Which two processing pathways are involved in visual processing?
Dorsal and ventral pathways.
What is the dorsal pathway in visual processing?
From V1 to parietal cortex. Processing spatial orientation. (WHERE)
What is the ventral pathway in visual processing?
From V1 to temporal cortext. Processing recognition and object form.
What is the role of LIP in attention?
LIP codes locus of attention, and codes for utility.
How can utility be learned?
With the dopamine system.
Where is the dopamine system located?
In the basal ganglia.
Which two pathways occur in the basal ganglia? (NOT IMPORTANT FOR EXAM)
Direct pathway –> facilitaites movement
Indirect pathway –> inhibits movements
