Forgetting Flashcards
What causes forgetting information in the STM?
- limited capacity (info displaced)
- limited duration (info decayed)
What causes forgetting information in the LTM?
- decay
- stored but hard to retrieve = accessibility problem
- information confused = interference problem
2 types of inteference?
Retroactive
Proactive
What is retroactive inteference?
New information interferes with old information
Underwood and Postman study for retroactive inteference
What is proactive inteference?
When old information interferes with new information
Underwood study for proactive interference
Interference theory strengths (2) and weaknesses (2)
+ supported by loads of lab experiments
+ evidence for real-world settings e.g struggle to remember french after learning german
- effects seem much greater in artificial lab settings so may not be as strong as suggested
- explanation for why we forget but doesn’t explain processes involved
How may recall depend on cues?
When forgetting is treated as retrieval failure, we have more chance of retrieving the memory if the cue is appropriate.
Cues can be internal (e.g mood) or external (e.g context/situation)
What is cue-dependent learning
When we remember more if we are in the same context/mood as we were when we coded the information originally
Tulving and Psotka - Forgetting in LTM
Cue-dependent learning strengths (1) and weaknesses (2)
+ strongest evidence. suggests all memory is available in LTM - we just need the right cue to access it.
- experiments very artificial (e.g word lists) so lack ecological vlue and hard to generalise into the real world + almost impossible to test if all memory is stored in LTM
- doesn’t explain all types of memory e.g cues might not be relevant to procedural memory (like riding a bike)
What is eyewitness testimony?
the evidence provided by people who witnessed a particular event or crime. It relies on recall information
What are leading questions?
a question where a certain answer is implied in the question
