1. Why does the temporal gradient in amnesia occur for older memories?

  • Because they havent been retrieved as much, their quality and neural basis changes into more episodic memory
  • Because they have been retrieved more, their quality and neural basis changes into more episodic memory
  • Because they have been retrieved more, their quality and neural basis changes into more semantic memory
  • Because they havent been retrieved as much, their quality and neural basis changes into more semantic memory

2. Which of these characterises an anterior lobe (ATL) memory system?

  • Encoding and recreating unique multimodal experiences of people/places/objects/events (semantic memory)
  • Encoding and recreating unique multimodal experiences of people/places/objects/events (episodic memory)
  • Extraction of similarities between multimodal experiences to create concepts (ie semantic memory)
  • Extraction of similarities between multimodal experiences to retrieve concepts (ie episodic memory)

3. Which memory type is self referential?

  • Episodic
  • Semantic

4. What does the lesion at 28 days with intact memory in Kim & Fanselow (1992) suggest?

  • If LTP disrupted immediately after the event, successful encoding does not occur no long lasting memory formed
  • Memory no longer 'in' the hippocampus, consoldated
  • Memory no longer 'in' the neocortex, consolidated
  • After a day memory is still in the hippocampus

5. Which of these is characteristic of semantic dementia (SD)?

  • Progressive loss of conceptual knowledge across modalities
  • Degeneration of frontal parietal areas
  • Atrophy in hippocampus and amygdala
  • Progressive loss of verbal concepts and knowledge for events
