Lecture 20 - Forgetting Flashcards
(lecture):
Describe incidental forgetting.
Describe motivated forgetting.
(lecture):
Memory failure without the intention to forget.
People engage processes and behaviours that intentionally diminish the memory. Usually due to trauma.
(lecture):
Why can forgetting some things be a good thing?
(lecture):
Traumatic events, you don’t have to relive them.
Read slide 5
(lecture):
What relationship is there between time and forgetting?
(lecture):
A logarithmic relationship
See slide 6
Not representative so see slide 7-8
Recall is worse than recognition.
(lecture):
Read slide 9
(lecture):
(lecture):
What is trace decay?
(lecture):
See slide 10
(lecture):
Describe interference of memories.
(lecture):
See slide 11-12
(lecture):
Describe retroactive interference.
(lecture):
See slide 13-14
(lecture):
Describe proactive interference.
(lecture):
See slide 15
(lecture):
Describe retrieval-induced forgetting (RIF)
(lecture):
See slide 16
(lecture):
How can we see retrieval-induced forgetting (RIF) in the real world?
(lecture):
See slide 17
(lecture):
Describe the interference mechanism: Blocking.
(lecture):
See slide 18
(lecture):
Describe the interference mechanism: Inhibition.
(lecture):
See slide 19-22
(lecture):
CONCLUSIONS
Forgetting increases over time: logarithmic.
• Forgetting occurs when the item is unavailable or
inaccessible.
• Why does forgetting occur?
- Trace decay
- Interference (proactive and retroactive)
- Retrieval-induced forgetting (RIF)
• Mechanisms underlying interference
- Blocking
- Inhibition
