Lecture 5 Flashcards
Autobiographical memory
Memory across lifespan for both specific events and self related info
-a function of memory (rather than a system)
—how we represent our individual lives in memory
Conway theory
Concerns representation of autobiographical memory
-representation corresponds to
a. Event specific memories
b. General events
c. Lifetime periods
-these levels create interacting, hierarchy structure in our memory
-Specific events -> organized into general events-> organized into cohesive units (liftetime periods)
Trace theory of memory
Belief that memory is like a video recording that can be preserved, unchanged, and replayed over and over
-replaying a memory is like reliving/re-experiencing and event
Reappearance hypothesis
Memory can appear again and again, unchanged
-like a tape recorder
-rejected by Neisser 1967
Flashbulb memories
Vivid, detailed memories of significant events
-people are able to report a lot of detail about
—where they were
—who told them
—their emotional reaction
Now print theory
Whole episode was snap shot and I printed in memory as such
-experiences that exceed critical levels of surprisingness and consequentiality
—Implicates that these memories will be accurate
Accuracy or flashbulb memories
-subject to same distortions and inaccuracies as normal memories
-but the confidence with which with which we assert these memories is their hallmark
—they are not necess more accurate
Ordinary mechanism approach
Flashbulb memories are normal memories but if emotionally shared events
-therefore, normal encoding and retrieving mechanism are still used
—inconsistencies show that peoples later recall is schema consistent
Consolidation theory
Memory traces of an event are not fully formed immediately after an event (take time)
—interruption of consolidation yields inability to recall
—mental inactivity should increase consolidation (sleep on it)
Retroactive interference
Consolidation could be disrupted by events that occur after the event that is to be remembered
Proactive interference
Older info interferes with the ability to remember or learn new info
Forgetting
-a crucial process
-access to previous info needs to be prioritized so that most relevant info is retrieved
—may be adaptive to lose some info/ blend together info from different episodes
Highly superior autobiographical memory (HSAM)
-some people exhibit extraordinary memory for autobiographical events over many years
—may be due to superior functional communication between prefrontal cortex and hippocampus (santangelo 2018)
Reconsolidation
a memory trace is revised upon deactivation due to coming into contact with other experiences
Schema theory of memory (Bartlett 1932)
- Method of repeated reproduction
-participants read material and reproduce 15 minutes later, and at longer subsequent intervals - Method of serial reproduction
-participants read material given something to read, recalls, and gives recollection to second participant (and then 3rd, and so on)
—both methods yielded similar results, but most dramatic with serial (rationalization—participants try to make memory as coherent principles)
Conclusion: memory is an imaginative reconstruction
