Wk4 - Visuospatial Sketchpad Flashcards
What does the visuospatial sketchpad do?
Rehearses and encodes visual and spatial information (e.g., images, navigation, spatial awareness)
What can disrupt storage of visuospatial memory?
Presentation of irrelevant visual items
Concurrent spatial processing (e.g., tracking a moving sound source)
Where does evidence for the biological basis of the visuospatial sketchpad come from?
Mental rotation tasks
What brain regions are related to the visuospatial sketchpad, according to activations from mental rotation tasks?
Parietal and occipital lobes
Is the visuospatial sketchpad unitary or non-unitary?
Non-unitary
What are the two processing pathways of the visuospatial sketchpad?
What pathway (visual)
Where pathway (spatial)
Define visual
The encoding and recognition of what an object is
Define spatial
The encoding of where an object is
Expand on the ‘what’ pathway
Ventral pathway. Relevant for object identification. Ends in the inferior temporal lobe.
Expand on the ‘where’ pathway
Dorsal pathway. Relevant for spatial information. Ends in the parietal cortex.
Who identified the ‘what’ and ‘where’ visual streams of processing?
Goodale et al. (1994)
What does the visual cache contain?
Visual or object-related information
What is the visual cache?
A passive visual store
Where is the visual cache found?
Left inferior temporal lobe
Anterior occipital lobe
What stream of processing is the visual cache involved with?
Ventral ‘what’ stream of visual processing (object recognition)
