42
Q

Concept Check: Most people with PTSD have lower than normal levels of cortisol what would you predict about their memory?

A

That due to the low cortisol levels, they have a harder time remembering information

43
Q

What is the primacy effect?

A

It means you’re more likely to remember something that happened first. ex. recalling the first couple items on a grocery list

44
Q

What is the recency effect?

A

The ability to remember the final items ex. the last couple of items on the grocery list

45
Q

Concept check: If you are studying vocabulary for a foreign language course, which words will you probably learn faster?

A

The words that were introduced first or last. As well as other words that stood out for any particular reason.

46
Q

What is the depth of processing principle?

A

That you can better retrieve a memory when you form associations with it which usually helps it store better for LTM

47
Q

Concept Check: Many of the students who read the assigned text chapters slowly get higher grades than students who didn’t. Why?

A

Because doing so allowed the students to engage in the reading by forming more connections to the material. Which uses the depth of processing principle.

48
Q

What are retrieval cues for memory?

A

Cues that help you retrieve information from your memory

49
Q

What is the encoding specifity principle?

A

The associations that is formed when learning new information is what will be most useful for retrieving the information later

50
Q

Concept Check: Suppose someone cannot remember what happened at a party last night. What steps might someone take to remember what happened?

A

Try to go back to where the party was at the same time with the same people

51
Q

Concept Check: Why do instructors call upon students to answer questions about what they just learned?

A

To help students remember the information better.

52
Q

Concept Check: Is the advice to spread out your study consistent with the encoding specify principle?

A

Yes, because it allows to reinforce those connections that were previously made while also being able to form more to strengthen the recall of the information

53
Q

What is mnemonic device?

A

A memory device that is used to help people remember things ex. acronyms like ADPIE

54
Q

What is the method of loci in terms of mnemonic devices?

A

It is when you associate places to help you memorize something. ex using your way to class to help you remember the functions of a cell

55
Q

What does consolidation mean?

A

It’s the process of converting STM to LTM

56
Q

What does reconsolidation mean?

A

It means to modify episodic memories or build upon information from semantic ones

57
Q

Concept Check: Suppose you tested a group of people for the memory of an event 1,5,10,15, and 20 days later to measure consolidation. What would be a better way to design that study?

A

An improvement to the formation of the study would be to have randomly assigned groups where one would only get tested after a day, and have the other get tested for multiple days afterward.

58
Q

What is hypermnesia?

A

It is when you gain more memories over time

59
Q

What is retrieval induced forgetting?

A

When you are asked a specific question about a larger idea/event/ topic you forget the other information about it as a whole. ex getting asked about a hike on a road trip which then makes it harder to recall other details about the trip as a whole

60
Q

What is reconstruction?

A

When you try to retrieve a memory about an event you in part reconstruct it based on information that you know

61
Q

Concept Check: Sometimes two people who shared the same experience months or years ago remember it differently. Why

A

They remember it differently based on their reconstruction of the memory.

62
Q

Concept Check: In history books, it seems that one event led to another in a logical order, but in everyday life, events seem illogical, unconnected, and unpredictable. Why?

A

Because in reconstruction of events people over time tend to forget the odd or unusual things that happened meaning that they probably get left out.

63
Q

What is hindsight bias?

A

When people tend to use information after the fact to shape what they had expected beforehand. ex people before the election saying which candidate they think they is going to win before changing their opinions after the fact

A) Encoding specificity principle
B) Hypermnesia
C) Hindsight bias
D) Depth-of processing principle

A

C

71
Q

What is proactive interference?

A

The old materials increase the forgetting of new materials because they of how similar they are to each other

72
Q

What is retroactive interference?

A

It is when new materials increase the forgetting of old materials

73
Q

Concept Check: Every year, you try to learn the names of all the other students in your class. Over the years you find that you struggle to learn the new ones more than you used to. Is this an example of retroactive or proactive interference?

A

Proactive because previous learning is affecting current learning

74
Q

Concept Check: Remember the concept of spontaneous recovery in learning? Can you explain it in terms of proactive interference? (Hint: Original learning comes first, and extinction comes second. What would happen if the first interfered with the second?)

A

The original learning interferes with the extinction (that comes later), the result is spontaneous recovery.

75
Q

What are recovered memories?

A

Memories that have been recovered from events that occurred years ago

76
Q

What is the repression of a memory?

A

It when consciously retaining the memory becomes too painful to bear that it end up in the unconscious mind

77
Q

What is the disassociation of a memory?

A

A memory that someone has but cannot recall

78
Q

Is repression or disassociation real?

A

Not really, there has never been studies that have been able to prove it. People usually remember traumatic events and it is rare to forget unless it happened at an early age

79
Q

Concept Check: Based on the material earlier in this chapter, why should we expect traumatic events to be remembered better than most other events?

A

Because memories with strong personal associations such as emotions will help the person remember the event better

80
Q

What is a false memory?

A

Memory of an event that someone believes to be true

81
Q

What is amnesia?

A

Loss of memory but not all memories

82
Q

What part of HM’s brain was removed to prevent seizures?

A

The hippocampus

83
Q

What is anterograde amnesia?

A

When someone is no longer able to store long term memories

84
Q

What is retrograde amnesia?

A

loss of memory for events that occurred before the trauma occurred

85
Q

Concept Check: What did studies on HM teach us about memory?

A

That people can hold information for a while in short term memory without it going to long term memory. Showed that procedural memory is different from declarative memory especially episodic memory. It is also possible to retain old sematic memories without being able to gain new ones.

86
Q

How is Korsakoff’s syndrome caused?

A

It is caused by a deficiency of vitamin B which is usually caused by alcoholism

87
Q

What are the effects of Korsakoff’s syndrome?

A

Due to the reduction of neurons in the prefrontal cortex patients tend to become apathetic, have more confusion, and amnesia

88
Q

What are confabulations?

A

It is a term used to describe when patients with prefrontal cortex damage try to answer questions with Confabulations to fill in the memories that they are missing

89
Q

TQ: Although confabulation is a kind of false memory, how does it differ from the false memories discussed earlier in this discussion?

A

Rather than it being a false memory it is an attempt to fill in the gaps of memories that make an actual event.

90
Q

What is Alzheimer’s disease?

A

A condition that mainly affects those over 65 years of age. When someone suffers extreme memory loss, confusion, depression, disordered thinking, and impaired attention

91
Q

What does early childhood amnesia mean?

A

It defines the phenomenon of many people who have few memories of their early childhood

92
Q

Concept check: Why is an example of infantile amnesia in rodents important to understanding it in humans?

A

Because it proves some of the other theories about childhood amnesia wrong and demonstrate that it is due to rapid brain development in the hippocampus

93
Q

TQ: How does proactive indifference differ from retroactive indifference?
A) Proactive interference accelerates forgetting of only short-term memory
B) Proactive interference accelerates forgetting of only implicit memories
C) Proactive interference accelerates forgetting of what you learned earlier
D) Proactive interference accelerates forgetting of what you learn later
