A

“What” - Stores general knowledge, or objective facts & info not directly linked to life events. 10x10=100, 1 dozen means 12, Capital of Canada is Ottawa

25
Q

How do we measure memory?

A

Recall, cued recall (with retrieval cues), recognition (MC questions), the relearning method

26
Q

Function hippocampus

A

essential for normal recognition tasks BUT when short time delays are involved, face recognition may be possible with hippocampal damage.

27
Q

How do we use relearning method in measuring method?

A

retention is expressed as the % of time saved when material is relearned compared with the time required to learn the material originally.

28
Q

What was Aristotle’s view on remembering?

A

the senses imprint memories in the brain like wax

29
Q

What was Freud’s view on remembering?

A

all memories are permanently preserved…some remaining in the unconscious

30
Q

What was Penfield’s view on remembering?

A

experiences leave a permanent imprint on the brain as though a tape recorder had been receiving it all

31
Q

Why are our memories distorted?

A

We make information fit, reconstruct our memories, put their point of view

32
Q

Schemas

A

Integrating knowledge and assumptions about people, objects and events. help us process large amounts of material by providing us with frameworks to incorporate new information.

33
Q

Positive bias

A

89% of college students accurately remembered the A’s but only 29% remembered accurately the D’s

34
Q

Distortion

A

This helps us organize our experiences into our existing systems of beliefs and expectations.
This can lead to BIG inaccuracies
(writing the word sleep)

35
Q

Does hypnosis improve memory accuracy?

A

Hypnosis doesn’t improve the accuracy of memory, but does the confidence in the memory

36
Q

What is the misinformation effect?

A

Leading questions can substantially change a witness’s memory of an event.

37
Q

Elizabeth Loftus

A

Studied the misinformation effect

38
Q

Unusual memory phenomena

A

Flashbulb memory, Eldetic imagery

39
Q

Flashbulb memory

A

burned into our brains!

Why? Memories in emotionally charged times, paired with hormone released, & involvement of amygdala set memories

40
Q

Eidetic imagery

A

(5% of children)
Ability to retain image of a visual stimulus for several
minutes after it is out of view

41
Q

Serial Position Effect

A

For information learned in sequence: Recall is better for items at the beginning (primacy effect) and at the end (recency effect).

42
Q

Context-dependent memory

A

Info easier to recall in same env’tal context as when
learned.
Odour, songs, influence recall.
Bring the witness back to the scene of the crime!

43
Q

State-dependent memory

A

Info easier to recall in the same emotional state as when
learned (sad, happy, intoxicated, sober)
Depressed people tend to remember more negative life experiences

44
Q

What is it to forget?

A

Inability to recall something we used to know

45
Q

Ebbinghaus’s Curve of Forgetting

A

He demonstrated that forgetting begins very early but then tapers off.

46
Q

What are causes of forgetting?

A
Encoding failure
Decay theory
Proactive Interference
Retroactive Interference
Consolidation failure
Motivated forgetting
Retrieval failure
Prospective forgetting
47
Q

Encoding failure

A

not forgetting, never learned in the first place – did not

enter LTM

48
Q

Decay theory

A

If memories are not used, they fade away and ultimately disappear. Generally accepted for sensory and STM, but not LTM (high school year book experiment). Implies a physiological change in the neural trace

49
Q

Proactive Interference

A

previously learned info interferes with ability to learn new info

50
Q

Retroactive Interference

A

new information interferes with our ability

to remember older information

51
Q

Consolidation failure

A

Disruption that prevents memory from forming
 Anything that causes a person to lose consciousness: blow to the head, car accident
 Amnesia
 memory loss, either partial or complete, resulting from
brain trauma, or psychological trauma.

52
Q

Motivated forgetting

A

Assault &/or disaster survivors are motivated to forget
to protect themselves from pain and/or fear
 Repression
 memory removed from consciousness; no longer aware event ever occurred.

53
Q

Retrieval failure

A

We are sure we know something, but we are not
able to retrieve the information we need.
Tip-of-the tongue phenomenon

54
Q

Prospective forgetting

A

Forgetting to remember: birthdays, appointments

Prospective memory: remembering to carry out an action in the future.

55
Q

Hippocampuses role in memory

A

critical area of brain involved in processing long-term memory

56
Q

Anterograde amnesia

A

damage to the hippocampus renders unable to put current (new) memories into long-term memory

57
Q

Retrograde amnesia

A

Memory loss; inability to remember past memories

58
Q

Source amnesia

A

Remembers information, but not the source. Forgets or misremembers,
“didn‘t you tell me that?”

59
Q

How improve memory?

A

Organization, over learning, massed practice more effective than spaced practice, active learning

60
Q

Mnemonic devices

A

The First-letter Technique

The Method of Loci (tells a story), Keyword Method

61
Q

CISD

A

critical incident stress debriefing
3 hour session asking individual to go over every detail
Doesnt work

62
Q

Karim Nader

A

blocked protein synthesis during recall
