Says that when you learn something your immediate recall is pretty good. It drops quickly then levels off into hours and days
|
|
Spacing effect
|
We retain information better when we rehearse over time
|
|
Next-in-line effect
|
When you are so anxious about being next that you cannot remember what the person just before you in line says, but you can recall what other people around you say
|
|
Visual encoding
|
When we try to picture something; worst retention
|
|
Imagery
|
Being able to put a picture to a word to remember it
|
|
Rosy retrospection

A method of learning, typically verbal, used to aid in memorization or thought recovery

Imagining yourself in a place to help remember what to say/do
|
|
Peg word approach
|
Jingle; association
|
|
Acoustic encoding
|
Hearing
|
|
Semantic encoding
|
Encoding the meaning; when you get the meaning of a word you're less likely to forget it; best retention
|
|
Karl Lashley
|
Suggested that even after removing parts of the brain, the animals retain partial memory of the maze; wanted to see if memory was still intact. No matter what part of the brain was cut out, at least partial memory was still there
|
|
Kandel and Schwartz
|
Showed that serotonin release from neurons increases after conditioning
|
|
Long-term potentiation (LTP)
|
Refers to synaptic enhancement after learning. An increase in neurotramsitter release or receptors on the receiving neurons indicates strengthening of synapses
|
|
Stress hormones and memory
|
Heightened emotions (stress-related or otherwise) make for stronger memories. Continued stress may disrupt memory
|
|
Amnesia
|
More likely to have explicit memory loss
|
|
Retrograde amnesia
|
Can't remember events before the trauma
|
|
Anterograde amnesia
|
Can't make new memories after the trauma
|
|
Implicit memory (procedural)
|
Involves learning an action while the individual does not know or declare what she knows
|
|
Explicit memory (declarative)
|
Refers to facts and experiences that one can consciously know and declare
|
|
Hippocampus
|
Memory processed here
|
|
Infantile amnesia
|
Hippocampus not fully developed before age of 3 so you can't remember life as an infant
|
|
Retrieval
|
Refers to getting information out of the memory store
|
|
Recall
|
The person must retrieve information using effort
|
|
Recognition
|
The person must identify an item amongst other choices
|
|
Relearning
|
The individual shows how much time (or effort) is saved when learning material for the second time
|
|

|
To retrieve a specific memory from the web of associations, you must first activate one of the strands that leads to it

|
Context-dependent memory

Scuba divers recall more words underwater if they learned the list underwater, while they recall more words on land if they learned that list on land
|
|

You remember if you are in the same state of mind as when you learned it; if you're studying while happy you'll remember more when you're happy than when you're sad
|
|
Deja vu
|
Cues from the current situation may unconsciously trigger retrieval of an earlier similar experience
|
|
