|
What happens when we learn something? |
We shape and strengthen our brain - plasticity. Blood capillaries flow more blood and oxygen. Glial cells increase in size. Myeline increases and new neurons are created in the hippocampus. |
|
|
How does learning occur? |
Classical conditioning
Operant conditioning |
|
|
What is an engram? |
A physical representation of what has been learned. |
|
|
What did lashley figure out? |
He found out that no significant cut interfered however when portions of the cerebral cortex was removed it imapired memory |
|
|
What is equipotentiality? |
All parts contribute equally. |
|
|
Mass action |
The cortex works as a whole |
|
|
Gist memory |
People remember the gist of the word |
|
|
Recall memory |
Reconstruction of elements scattered through various areas of the brain |
|
|
How does information become part of the LTM? |
Elaboration Organisation Context |
|
|
What is episodic memory? |
Autobiographic memory |
|
|
What is semantic memory? |
Factual information and general knowledge |
|
|
What is procedural memory? |

|
|
What is a nonmatching-to-sample task? |
You are shown a sample and you choose an object which was not show before. |
|
|
What happens if there is high metabolic activity? |
Cells become more vulnerable, there is damage to the hippocampal neurons and this leads to memory impairment. |
|
|
What is korsakoff syndrome? |

What causes amnesia? |
Abnormal clumps
