27
Q

27
Q

learning that is associated with a particular internal state, such as mood or state of awareness.

A

28
Q

transfer appropriate processing

29
Q

When the type of task that occurs during encoding matches the type of task that occurs during retrieval. This type of processing can result in enhanced memory.

A

transfer appropriate processing

30
Q

Participants who did a rhyming-based encoding task did better on the rhyming test than participants who did a meaning-based encoding task is an example of what matching condition?

A

transfer appropriate processing

31
Q

the process that transforms new memories from a fragile state, in which they can be disrupted, to a more permanent state, in which they are resistant to disruption.

A

consolidation

32
Q

consolidation that takes place over minutes or hours, involves structural changes at synapses.

A

synaptic

33
Q

consolidation that takes place over months or even years, involves the gradual reorganization of neural circuits within the brain

A

systems

34
Q

One of the outcomes of structural changes at the synapse is a strengthening of synaptic transmission. This strengthening results in a phenomenon where enhanced firing of neurons occur after repeated stimulation

A

long-term potentiation (LTP)—

35
Q

According to Hebb, learning and memory are represented in the brain by physiological changes that take place at the _______.

A

synapse

36
Q

Researchers who followed Hebb’s lead determined that activity at the synapse causes a sequence of chemical reactions, which result in the synthesis of new proteins that cause structural changes at the ________

A

synapse

37
Q

The case of HM, who lost his ability to form new memories after his hippocampus was removed indicates the importance of the hippocampus in what?

A

forming new memories

38
Q

Proposes that memory retrieval depends on the hippocampus during consolidation, but that once consolidation is complete, retrieval no longer depends on the hippocampus.

A

standard model of consolidation

39
Q

the hippocampus, is involved in encoding new memories, and makes connections with higher cortical areas . However, with the passage of time, connections between the hippocampus and cortical areas weaken, and connections between cortical areas strengthen until, eventually, the HC is no longer involved in those memories

A

standard model of consolidation

40
Q

According to this model, the participation of the hippocampus is crucial during
early stages of memory, as it is replaying the neural activity associated with a memory and sending this information to the cortex.

A

standard model of consolidation

41
Q

A process that occurs during memory consolidation, in which the hippocampus replays the neural activity associated with a memory. During reactivation, activity occurs in the network connecting the hippocampus and the cortex. This activity results in the formation of connections between the cortical areas.

A

reactivation

42
Q

This loss of memory for events that occurred before the injury, called ________ amnesia, can extend back minutes, hours, or even years, depending on the nature of the injury.

A

retrograde amnesia,

43
Q

a characteristic of retrograde amnesia on which the amnesia tends to be most severe for events that happened just before the injury and to become less severe for earlier events

A

graded amnesia

44
Q

model that proposes that early in consolidation, the hippocampus communicates with cortical areas. However, in this model the hippocampus remains in active communication with the cortical areas, even for remote memories

A

multiple trace model

45
Q

Bonnici found that (1) more information about remote memories compared to recent memories was contained in the __________, and (2) information about both recent and remote memories was represented throughout the hippocampus, with the posterior hippocampus containing more information about ________ memories

A
  • prefrontal cortex
  • remote
46
Q

the reason sleep shortly after learning enhance memory is because it eliminates ________

A

distraction

47
Q

the idea that when a memory is retrieved (remembered), it becomes fragile, like it was when it was originally formed, and that when it is in this fragile state, it needs to be consolidated again

A

reconsolidation

48
Q

when the memory has become fragile again, and before it has been reconsolidated, it can be _______ or ________.

A

modified or eliminated

49
Q

according to __________, retrieving a memory not only puts us in touch with something that happened in the past, but it also opens the door for either modifying or forgetting the original memory

A

reconsolidation

50
Q

just as the original memory is fragile until it is _______ for the first time, a reactivated memory becomes fragile until it is __________.

A
  • consolidated
  • reconsolidated
51
Q

This idea that memories can be changed, has led to practical applications designed to treat conditions such as

A

PTSD

52
Q

The evidence from Almut Hupbach’s experiment with the reminder and no-reminder groups showed that _________ memories in humans can become vulnerable to change, leading to the integration of new information from List B into the originally recalled List A.

A

reactivated

53
Q

Two explanations have been proposed to explain the results of Hupbach’s experiments in which human memories were reactivated. One explanation involves __________, the other involves considering the _______ in which learning takes place.

A
  • reconsolidation
  • context
54
Q

The ___________ model focuses on the context within which learning and retrieval occur and assumes that old contexts can become associated with new memories, without changing the content of existing memories

A

temporal context

55
Q

When cued with the old context, both the existing and the new memory will be recalled. Thus, the _________ explanation proposes that what is stored about the old memory has changed, whereas the ________ explanation proposes that considering storage is unnecessary because Hupbach’s result can be explained by contextual associations.

A
  • reconsolidation
  • temporal context
56
Q

what is the key difference between synaptic consolidation and systems consolidation?

  • content
  • scale
  • state
  • consciousness
A

scale

57
Q

Hebs idea of long term potentiation, which provides a physiological mechanism for the long term storage of memories, includes the idea of what?

  • an increase in the size of cell bodies of neurons
  • increased firing in the neurons
  • larger electrical impulses
  • the growth of new dendrites
A
  • increased firing in the neurons
58
Q

Bradford and Johnsons study had participants hear a passage, which turned out to be about a man on a street serenading his girlfriend in a tall building. the wording of the passage made it difficult to understand, but looking at a picture made it easier to understand. the results of this study illustrate the importance of _________ in formulating reliable long term memories

a) implicit memory
b) organisational context
c) reconsolidation

A

organisational context
