Q

Thompson’s studies on classical conditioning demonstrated

A

the association between a neural stimulus and an unconditioned stimulus; pairing the two changes the response to the formerly neural stimulus called a conditioned response

Q

Sensory memory

A

a copy of sensory info that you have just processed; very short lasting
thought to be “stored” in the associated primary sensory areas

Q

How can we experimentally distinguish between STM and LTM?

A

Nature of representation
Stability/Duration
Capacity
Brain Region

20
Q

Explicit memory is associated with which brain region

A

medial temporal

21
Q

Implicit memory is associated with which brain region

A

neocortex

22
Q

What is amnesia?

A

the inability to retain information for longer than a few minutes. Typically considered long-term memory impairment

23
Q

Amnesia is caused by

A

damage to parts of the brain vital to memory consolidation, storage, processing, and recall

24
Q

The effects of amnesia vary by

A

brain region

25
Q

What did the H.M. case study illustrate about H.M.’s post-surgery abilities?

A

after having the hippocampus, amygdala, and adjacent cortex removed his STM was normal but his LTM was damaged. He could not form memories for new events so he had anterograde amnesia, more specifically explicit memory deficit

26
Q

H.M.’s case demonstrated

A

there are small regions (medial temporal lobes) with different effects therefore mnemonic functions are NOT equally represented; first evidence that there are different kinds of memory

27
Q

The process involved in the different modes of storage for STM and LTM is referred to as

A

memory consolidation

28
Q

Issues with memory consolidation

A

inability to transfer the information in STM to LTM

29
Q

How is explicit memory used in our behavioral control?

A

explicit memory provides flexibility and control over our behavior; it allows you to apply learned skills in any context

30
Q

Which kind of amnesia does H.M. have?

A

Explicit memory Deficit
Anterograde Amnesia

31
Q

H.M. had particular trouble with which kind of LTM?

A

Memory for new events
Memory consolidation

32
Q

We know that H.M.’s implicit memory is intact because of his performance on which tests?

A

Mirror-drawing and Rotary-pursuit tests

33
Q

Korsakoff’s Syndrome

A

thiamine deficiency due to chronic alcohol consumption; related to retrograde and anterograde amnesia due to damage to the medial diencephalon and PFC

34
Q

PFC memory deficits

A

damage to the PFC associated with temporal ordering and working memory (e.g. Schizophrenia); poor performance on self-ordering task and remembering sequences of events

35
Q

Alzheimer’s disease is caused by

A

acetylcholine and extensive neural degeneration

36
Q

What have we learned from studying people with amnesia?

A

many different kinds of memory, modes or memory, and different brain regions associated with memory

37
Q

What are the limitations of studying amnesia?

A

Lesions are not specific, findings may not be generalizable, difficult to control

38
Q

Amnesia is always a short-term memory deficit (True/False)

A

False

39
Q

Amnesia is usually has deep retrograde effects (True/False)

A

False. It is very uncommon to completely forget childhood

40
Q

Amnesia does not involve problems with learning after injury (True/False)

A

False. Anterograde impairment is a common form of amnesia

41
Q

Animal studies of MTL function demonstrate

A

monkeys with lesions have normal performance at short delays but perform at chance levels with longer delays compared to control monkeys

42
Q

Which part of the MTL is really important for object recognition?

A

Rhinal cortex seems to play a more critical role in object recognition

43
Q

Hippocampus seems to play a critical role in remembering _____ and _____

A

spatial locations; navigating through space

44
Q

How does the hippocampus represent spatial information?

A

place cells found in the hippocampus fire more when the animal is in a specific location allowing you to create maps of the environment
