RECONSTRUCTING MEMORY DP 12 Flashcards
Reconstructive Nature of Memory
- combining stored info with other available info to form a more complete memory
- Each time we retrieve a memory we make up and add missing bits to complete the memory in a plausible or logical way
- Retrieved memories aren’t necessarily an exact reproduction of the og experience at the time of learning (Memory is fallible)
Reconstructing Memory / factors impacting distortion
- Memory is subject to personal interpretation it is dependent on a range of factors including cultural norms, emotion and values
- People store information in the way that makes the most sense to them
- Minor/insignificant events are overlooked
Eg. being told a detailed story about going to a restaurant and recalling the waitress gave a menu (even if it wasn’t stated) due to previous experiences
How is memory distorted?
During initial encoding, retrieval and reconsolidation, we reconstruct the memory to ensure it is complete in a logical/plausible way (without conscious awareness)
Repeated retrieval = further distortion
Eg. conversations w other ppl can create info that is integrated into memory
Leading Questions
- A question that prompts an individual to answer in a particular way
How do leading questions reconstruct memories?
- Loftus’ research makes it clear that leading questions can distort memories and manipulate memory reconstruction and therefore info that is reported by eyewitnesses is unreliable.
- Misinformation from leading questions becomes confused with the original memory
Elizabeth Loftus Research
- Loftus conducted research and experiments on the fallibility of memory
- Experiment: participants watched videos of car accidents and were asked different variations of leading questions about what they had witnessed, including an estimation of speed of collision.
- Variation in wording such as the intensity of the verb influenced the the average estimated speed. Eg: if experimenter said car hit, they said a lower speed if car smashed, they said higher speed
- Conclusion: memories were distorted by the verbal label used to describe intensity of the crash, causing memory to be incorrectly encoded/manipulated subconsciously (constructed memory)
- Continuation: 1 week later, w/out viewing experiment again, they were asked a leading question w planted info. Eg. did you see the broken glass? (there was no glass present)
- Results: wording of original question impacted whether they saw glass or not
Source confusion
Arises when true source of a memory is forgotten or when a memory is attributed to the wrong source (due to leading questions)
Fallibility of memory
- Loftus found that memories can be reconstructed to include new info that is learnt after an event, or due to leading questions
- Overtime, memory can be changed as it is reconsolidated into LTM
- Reconstruction of memories provides evidence for the fallibility (unreliability) of memory
Reconsolidation
A process in which previously stored memories, when retrieved, are altered before being stored again
