Q

What does the mirror drawing task show?

A

Showed procedural memory and that most people get better at the task without realizing it (H.M.)

Q

What is priming?

A

The change in the response to a stimulus or in the ability to identify a stimulus as the result of prior exposure to that stimulus?

Q

What are the stages of memory?

A

Encoding, Storage, Retrieval

18
Q

What is encoding?

A

The processing of incoming information to be stored

19
Q

What are the 2 steps involved in encoding?

A

Acquisition: registering sensory inputs
Consolidation: creating a stronger stored representation

20
Q

What is storage?

A

Permanent record of the information

21
Q

What is retrieval?

A

Utilizing stored information to recall conscious memory or execute learned behavior

22
Q

What are the parallels between attention and memory?

A

What we perceive is not necessarily what we see AND what we remember is not necessarily what we saw

23
Q

Why do false memories occur?

A

Failure in encoding (insufficient memory separation)
Failure in retrieval (low criteria for accepting a memory as true)

24
Q

What are forgotten memories?

A

They are also failures of storage (decay or interference of representations)

25
What is amnesia?
Deficit in memory as a function of brain damage, disease, or psychological trauma
26
What are the 2 types of amnesia?
Retrograde and Anterograde Amnesia
27
What is retrograde amnesia?
Loss of previous knowledge from before event
28
What is anterograde amnesia?
Inability to form new memories after event
29
Amnesia is caused by damage to what brain regions?
Bilateral medial temporal lobe (MTL)
30
What is Korsakoff's?
It is amnesia associated with alcoholism Long term alcohol abuse leads to vitamin B deficiency and then brain damage
31
What is Alzheimer's?
A degenerative brain disorder that occurs due to the formation of plaques and tangles in the Medial Temporal Lobe
32
What is the Hippocampus/MTL involved in (memory and learning)?
Encoding and retrieval Consolidation and ability to acquire long term memories
33
Where is information retrieved?
Hippocampus is only active during correct recollection but not familiarity
34
What part of the brain is involved in familiarity?
Perirhinal cortex (PRC)
35
What is episodic memory?
Binding of items and contexts (AKA Autobiographical memory)
36
What does the perirhinal cortex (PRC) do?
Represents information about specific items (what, who)
37
What does the parahippocampal cortex (PHC) do?
Represents information about context (where, when)
38
What is needed for a full episodic memory?
Need hippocampus
39
Where is information stored?
Content of memories stored in content-specific regions IN neocortex
40
What other brain areas are involved in memory?
Frontal Lobes (executive functions, encoding, retrieval) Parietal Lobes (attention) Still a continuous area of study
