Long Term Memory Flashcards
Depth of processing
- The deeper you encode the better you remember
- deeper based on meaning versus shallow
- dependent on test type I.e recall vs recognition
Recall vs recognition
Recall: recollection
Recognition: familiarity
- info lost or not accessible
Self relevant information
We tend to remember information that is relevant to us or that we generated
- sue to depth of processing
Organization of information
Info organized in semantic ways, where we can gain insight how knowledge is organized with recall items
- order of recalled items indicates how closely connected item is to that category.
How information is coded in LTM?
-LTM encodes info semantically for storage
-imformation must enter working memory before it can be stored in LTM
- speed with which info is stored into LTM determined by amount of info that can fit into each step of visual working memory.
Dual code theory (Paivo)
Info can be stored in verbal and/ or imaginable codes.
- more codes = better memory
-concrete words better remembered than abstract words.
Synaptic consolidation
Changes happening at synapse level
Systems consolidation
Standard trace level:
Multiple Trace Level:
Consolidation and sleep
LTP occurs during sleep
- don’t nap get a full cycle when studying so synapse can retain information
Reconsolidation
Every time you bring up a memory it is reconsolidated/reorganized because of new memory
Autobiographical memory
-Memories related to self
-way of studying memory
-Difficult because you can’t check accuracy
The way we remember our life’s affects who we are
Flashbulb memories
Significant emotionally arousing events
-feels more accurate (more confidence)
-you can retell events over/over again
-further in past less details remembered
Infantile Amnesia
Poor memories of early events, we have limited memory before age 5 because our hippocampus isn’t developed untill 5
Eye witness memory issue
Retrieval is very efficient for learning
Ronald Cotten rape case: girl put wrong guys in jail due to false eyewitness testimony
Line up procedure
- Should have not there option
-sequential (one at a time) more accurate than simultaneous ( lineup) - recognition/familiarity
