Retrieval failure Flashcards
(14 cards)
What does the retrieval failure theory of forgetting suggest forgetting is due to?
Inability to access memory
How does retrieval occur then?
Retrieval therefore depends upon using cues
What are the two types of cues?
- External (context-dependent)
- Internal (state-dependent)
What are context dependent cues mainly about?
The environment
What are state-dependent cues mainly about?
Emotions/mood
Who proposed the encoding-specificity principle?
Tulving and Thompson
What is the encoding-specificity principle?
- memory is at its best when information is present at the time of coding is also available at the time of retrieval
- a cue does not have to be right but the closer it is to the original item the more useful it is
- Cues that have been implicitly or explicitly linked at time of encoding can have a meaningful link
APFC of context-dependent forgetting by Abernethy
- Aimed to investigate context-dependent forgetting
- Students were tested before their course began and then weekly
- Testing took place over four conditions
tested in their teaching room by same instructor,
tested in their teaching room by different instructor,
tested in a different room by same instructor,
tested in a different room by different instructor - She found that those tested by the same instructor in the same room performed best
- Abernethy concluded that familiar things (room/instructor) acted as memory cues and aided the students ability to recall information
Describe Goodwin et al study that looked at state-dependent forgetting
- aimed to investigate state-dependent forgetting
- asking male volunteers to remember lists of words either drunk or sober
- ppts were asked to recall this list after 24h, when some were sober, whilst other still drunk
- found that information learnt when sober is more available when in the same state
- ppts who were drunk at learning were able to recall whilst drunk
- concluded that the mental state you are in at time of learning can also act as a cue
- supporting the idea of state-dependent forgetting
What are some problems with Goodwin et al study?
- gender bias
- unethical: getting drunk
Describe Goodwin and Baddeley’s study of deep sea divers
- field experiment
- deep sea divers either learnt word lists on land or underwater
- recall of the words was then tested in the same or different context
- those who learned and recalled in different context (e.g. learned on land, recalled underwater) did not perform as well as ppts who had learned and recalled in same context
- Ability to recall information depends upon the context in which learning takes place
A03 - Research support for retrieval failure as an explanation of forgetting in LTM
-evidence support for external cues is derived from a study by Abernethy who found the similar surroundings to time of learning acted as memory cue at time of recall
- In addition, Goodwin highlighted the importance of internal (state) cues. Ppts recalled information best when they were in the same state at time of learning
- Therefore these studies demonstrate the importance of context and state cues in the ability to later retrieve information
A03 - Challenge - not explain all forms of forgetting
- The information learnt is related to a lot more than cues
- For example, Milgram’s research into obedience, you learning about the complex associations that are less likely to be easily triggered by single cues
- This is called the outshining hypotheses
- According to Smith and Vela context effects are largely eliminated when learning meaningful material
- This suggests that retrieval cues can suggest instances of everyday forgetting by not explain everything
A03 - Testing the validity of retrieval failure
- Testing the validity of the theory has been questioned by some researchers who argue the theory to be circular
- A limitation is that encoding cues and later retrieval is a correlation rather than a cause
- Nairne calls this the ‘myth of encoding-retrieval match’
- Baddeley said that encoding-specificity principle is impossible to test because it is circular
- If a stimulus leads to memory retrieval then it must be encoded into memory
- If not lead to memory retrieval then according to encoding-specificity principle it can’t have been encoded into memory
- Therefore, this shows that cues do not cause retrieval they are just associated with retrieval
