Memory
You don’t know what you’ve got ‘til
it’s gone
Retrieval
• Getting information out of long-term
storage
• Memories are stored in a network of
related information
– Retrieval cues
– Priming
– Context
Déjà vu
• Sensation of reliving a previously
experienced situation
State-dependent memory
• Recall is aided by an emotional state that
is similar to that experienced during
encoding
– Happy
– Sad
– Angry
Forgetting
• Inability to retrieve information
– Can happen at any memory stage
• Encoding failure
– Information not encoded at any stage will be
forgotten
Anterograde amnesia
• Inability to for NEW declarative memories
– Failure of encoding
– Due to hippocampal damage
Forgetting
• Storage decay
– Encoded, stored
memories may be
lost
– Forgetting curve
• Less durable
memories are lost
most easily
Retrograde amnesia
• Large-scale loss of previously stored
memories
– Due to brain injury
– Time frame of loss varies
– Often temporary
Retrieval failure
• Some memories are not readily retrieved
from storage
– “Tip of the tongue” phenomenon
• Interference
– Proactive interference
– Retroactive interference
• Revision
Memory is a constructive
process
• Schemas
– New memories are fit into existing belief
structures
Memory is a constructive
process
• Memory recall is not an exact replica of
original events and information
– Recall is a reconstructing of memory based
on:
•
•
•
•
•
New experience, ideas, information
Alteration in the strength of some memories
Interaction with others
Filtering out information
Filling in missing pieces
Memory is a constructive
process
• Memory is influenced by faulty information
• Misinformation effect
– Loftus’s research on false memories
• Imagination
– We can create our own false memories
Memory is a constructive
process
• Source amnesia - inability to recall the
context in which information was learned
– Misattribution
Memory is a constructive
process
• Eyewitness recall - not as reliable as once
thought!
– Children’s recall
– Adult recall
Memory is a constructive
process
• Final thought:
Memory is a reconstructive process
and confidence is NOT correlated with accuracy!
