declaritive memory

Question 1

episodic memory provides answers to

Answer 1

what, when and where

Question 2

semantic memory lacks a …

Answer 2

particular connection to a time or place

Question 3

semantic network model: Collins and loftus 1975

Answer 3

> concepts are represented as nodes in an interconnected network
once a node is activated, activation spreads to connected nodes
Activity reduces with distance

Question 4

organisation of semantic memory

Answer 4

hierarchy of concepts = superordinae categories, basic level categories and subordinate categories (eg: animal, dog, poodle) : rosch et al 1976
> basic level = used 99% of the time, associated with the most appropiate action

Question 5

Barsalou’s situated simulation theory:

Answer 5

Concept processing is influenced by
Context
Perceptual and motor systems
Concepts are abstract and stable representations

Question 6

Barsalou’s theory, perceptual processing of abstract concepts….

Answer 6

Patients with damage to sensorimotor systems have no defecit in processing on manipuable objects
Concept knowledge > perceptual and motor features

Question 7

hub and spoke model ( Patterson et al 2008)

Answer 7

Hubs = abstract representations containing core knowledge of concepts
Hubs are stable and unchanging
Hubs are located within anterior temporal lobes
Patients with semantic dementia ( who have damage to anterior temporal lobes) have severely impaired hub knowledge of concepts
Spokes = each concept has several spokes as well as a hub, the spokes interact with the hubs
Spokes contain relatively specific information, much relating to sensory and motor processing
Activation of any given spoke depends on the individuals current goals and situation

Question 8

limitations of hub and spoke model?

Answer 8

Relations between concepts do not involve anterior temporal lobes
Unclear how information from hub and spokes is integrated
