3-Problems with memory Flashcards
DAMAGE TO THE HIPPOCAMPUS—AMNESIA
the loss of long-term memory that occurs as the result of disease, physical trauma, or psychological trauma
Declarative memory: episodic and semantic
Anterograde amnesia
- commonly caused by brain trauma
- Hippocampus is usually affected
- Issue with FUTUREEE
- Inability to make new episodic or semantic memories
- still has old episodic memories, just can’t make new episodic memories
- Still have their old memories
- Many people can still form new procedural memories
- Problem with consolidation
Reterograde amnesia
- Loss of memories prior to trauma
- Partial / full loss of memories
- Can make new memories
- Difficulty with episodic or semantic?
Construction:
making a new memory
Reconstruction
bringing up old memories
forgetting sins of memory
- transience
- absentmindedness
- blocking
distortion sins of memory
- misattribution
- suggestibility
- bias
intrusion sins of memory
persistence
FORGETTING
- rapid forgetting happens in the sensory and the short-term memory stage
- happens for long-term memory
encoding failure
memory loss happens before the actual memory process begins
Transience
forgetting that occurs with the passage of time
- Rapid forgetting happens in the sensory and short-term memory stage
- Happens for long-term memory
- Most information that is forgotten, is forgotten quickly
- Cramming…helps you if taken immediately, but most of that information is quickly forgotten
- Average person will lose 50% of the memorized information after 20 minutes and 70% of the information after 24 hours
part of what happens with transience is that other memories get in the way
retroactive interference
New information inhibits our ability to remember old information; interfering with old memory
Proactive interference
old information inhibits the ability to remember new information
Absentmindedness
a lapse in attention that results in a memory failure
- Incorporates encoding failures
- Semantic tasks shows lower activity in the LEFT lower frontal lobe
- Episodic memories shows lower activity in the hippocampus
Blocking
failure to retrieve information that is available in memory even though you are trying to produce it
- Tip-of-the-tongue phenomenon
- Information has been encoded and stored… is in long term memory… BUT IS PROBLEM WITH RETRIEVAL!
- Something is blocking you from accessing it
- Information that is not as strongly associated with related concepts/knowledge are more likely to be blocked
