Geheugen - Short-Term and Working Memory
10 important questions on Geheugen - Short-Term and Working Memory
What is long-term memory (LTM)?
What is articulatory suppression?
What are the two components of span tasks?
2. A rehearsal mechanism based on subvocal articulation that refreshes the store
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What is the neural basis of visuo-spatial STM?
What is the concept of working memory?
What are the four components of the working memory model?
2. A comparable system is postulated in the visual domain and termed the visuospatial sketchpad.
3. The episodic buffer maintains and manipulates information from episodic long-term memory
4. The central executive coördinates the other three (slave systems) and cognition in general
Propose that information gets transferred or copied into a seperate dedicated systeem which may then be acted on by an executive system.
What are the challanges of the model?
This is not a problem for traditional models, because capacity limitation is an intrinsic property of short term stores.
Which part of the brain plays a crucial role in working memory?
What is a hierarchical model of working memory?
In this model, the ventrolateral prefrontal cortex is responsible for activating, retrieving and maintaining information held in the posterior cortex. The dorsolateral prefrontal region is responsible when the information held within this system requires active manipulation.
What is the self-ordered pointing tasks (linked with prefrontal lesions)?
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
