Question 1

Vivid recollections of emotionally significant events, such as the assassination of John F.Kennedy or Martin Luther King, Jr.or the space shuttle disasters, are known as

Accepted Answer

Vivid recollections of emotionally significant events are called flashbulb memories. Flashbulb memories are highly detailed, vivid, and enduring recollections of an emotionally charged and consequential event that are typically formed shortly after the event and can be easily retrieved later. They are often described as feeling like a mental snapshot or photograph of the event. Examples of events that can lead to the formation of flashbulb memories include major public events, such as assassinations, terrorist attacks, or natural disasters, as well as personal events, such as births, deaths, or weddings.

Question 2

Memories for a response may be erased by

Accepted Answer

Administering brain shocks immediately after training can disrupt the formation and consolidation of memories, leading to their erasure. The other options (A, B, D) do not necessarily result in memory erasure.

Question 3

When an event is surprising, emotional, or important, it is likely to produce a(n) _____ memory.

Accepted Answer

Flashbulb memories are created during surprising or emotionally significant events and are characterized by vivid and detailed recall.

Question 4

Information and events occurring just before a head injury are remembered very poorly or not at all because

Accepted Answer

Consolidation is the process by which memories are formed and stored in long-term memory. A head injury can interrupt this process and prevent memories from being consolidated properly. As a result, information and events occurring just before a head injury may not be remembered well or at all.

Question 5

Regarding ECS and consolidation, which of the following statements is FALSE?

Accepted Answer

The false statement is that ECS will cause amnesia for memories that occur up to two hours after the ECS is administered. The disruption of memory by ECS is not limited to a specific time frame after learning, and there is no clear cut-off period beyond which memory is safe from disruption.

Question 6

The formation of long-term memories in the brain is known as

Accepted Answer

The formation of long-term memories in the brain is known as consolidation. This involves the strengthening of neural connections over time, allowing information to be stored for long periods of time. Memory localization refers to the specific brain regions involved in memory processing, mnemonic processing refers to specific techniques or strategies used to improve memory, and priming refers to the activation of previously stored information that can affect perception or behavior.

Question 7

José studies, stays awake for eight hours, then sleeps for eight hours.Santos studies, then sleeps eight hours, and is then awake for eight hours.Santos will experience less forgetting than José because more _____ will occur before the interference (of being awake) begins.

Accepted Answer

Consolidation refers to the process by which memories become stable and long-term. During sleep, consolidation occurs and memories are strengthened. Therefore, Santos will experience more consolidation before the interference of being awake, resulting in less forgetting compared to José.

Question 8

In the experiment in which a rat was administered an electroconvulsive shock (ECS) after receiving a painful shock to its feet, the rat experienced _____ regarding the painful shock to its feet.

Accepted Answer

The administration of an electroconvulsive shock (ECS) after receiving a painful shock to its feet is a form of aversive conditioning. This type of conditioning is known to cause retrograde amnesia, which is the inability to recall events that occurred before the time of the shock. Therefore, the rat in this experiment would not be able to remember the painful shock to its feet that occurred before the ECS.

Question 9

Consolidation is like writing your name in wet concrete.Once the concrete is set, the information (your name) is fairly lasting.But while it is setting, it can be wiped out in the case of _____ or scribbled over in the case of _____.

Accepted Answer

Consolidation refers to the process of stabilizing a memory trace after the initial acquisition. Amnesia can wipe out memories before they are fully consolidated, similar to erasing a name in wet concrete. Interference can alter or overwrite memories during consolidation, akin to scribbling over a name in wet concrete.

Question 10

Minnie has severe depression that has not been alleviated by medication.She is administered electro-convulsive therapy, that is, she is given a "shock treatment." We can expect Minnie to suffer a memory loss for events happening right before the shock treatment was administered.This memory loss is due to _____ being disrupted.

Accepted Answer

The memory loss that Minnie is expected to suffer from is due to disruption in consolidation, which is the process of strengthening and stabilizing a memory after it has been initially encoded. Electroconvulsive therapy can disrupt this process and cause memory loss for events happening right before the treatment. Constructive processing, redintegration, and priming of memories are not directly related to the memory loss caused by electroconvulsive therapy.

Question 11

Lasting images that are frozen in memory at times of personal tragedy, accident, or other significant events are called _____ memories.

Accepted Answer

Flashbulb memories are vivid and detailed recollections of significant events that are usually emotional in nature. They are often referred to as "snapshot" memories because they are frozen in time and highly resistant to forgetting.

Question 12

If enough time is allowed to pass between learning and an electroconvulsive shock (ECS), the memory will be unaffected because _____ is already complete.

Accepted Answer

Consolidation refers to the process of creating a stable memory trace in the brain. If enough time has passed for consolidation to occur, the memory will be resistant to disruption by ECS. Redintegration refers to the process of piecing together fragments of memories, positive transfer refers to the beneficial effects of past learning on acquiring new information, and constructive processing refers to the influence of prior knowledge on how new information is interpreted and recalled. None of these processes directly relate to the effect of ECS on memory consolidation.

Question 13

Electroconvulsive therapy has the side effect of causing memory loss because it disrupts

Accepted Answer

Electroconvulsive therapy (ECT) disrupts the process of consolidation, which is the conversion of short-term memories into long-term memories. This disruption can cause temporary or permanent memory loss, particularly for events that occurred close in time to the ECT treatment.

Question 14

Regarding consolidation, which of the following statements is TRUE?

Accepted Answer

Research suggests that the hippocampus plays a significant role in the consolidation of memories, particularly in the transfer of information from short-term to long-term memory. Option A is incorrect, as consolidation does not refer to the time it takes to retrieve information from LTM but rather to the process of strengthening new memories. Option B is incorrect, as electroconvulsive therapy can actually impair memory consolidation. Option D is incorrect, as consolidation does not cause the decay of memories in sensory and short-term memory, but rather the opposite - it leads to the strengthening and stability of memories in long-term memory.

Question 15

The occurrence of _____ implies that consolidation has been interrupted.

Accepted Answer

Retrograde amnesia implies that consolidation has been interrupted because it involves the loss of memories formed before a certain event, indicating that those memories were not fully consolidated.

Question 16

Consolidation refers to the

Accepted Answer

Consolidation refers to the process of converting a short-term memory into a long-term memory through the strengthening of neural connections in the brain. Therefore, the correct answer is D, the forming of a long-term memory.

Question 17

José studies, stays awake for eight hours, then sleeps for eight hours.Santos studies, then sleeps eight hours, and is then awake for eight hours.Regarding the amount of forgetting that each of these students will experience,

Accepted Answer

José sleeps immediately after studying, which makes it hard for his brain to consolidate the information. This means that he will likely forget more of what he studied compared to Santos, who studies and then stays awake for eight hours, allowing the brain to consolidate the information during this time.

Question 18

In an experiment, a rat was placed on a small platform.When this rat stepped down to the floor, it received a painful electric shock.After one shock, this rat would not step down to the floor when placed on the platform.A second rat also stepped down to the floor from the platform and received a painful shock but was immediately administered an electroconvulsive shock (ECS) to its brain.How did the ECS affect this second rat's behavior?

Accepted Answer

The ECS interfered with the memory consolidation process, preventing the second rat from remembering the painful shock, so it continued to step down.

Question 19

_____ is like writing your name in wet concrete.Once the concrete is set, the information (your name) is fairly lasting.But while it is setting, it can be wiped out (amnesia) or scribbled over (interference).

Accepted Answer

Consolidation refers to the process of converting information from short-term memory into long-term memory, which is a relatively stable and enduring form of memory storage. This process is often compared to writing your name in wet concrete because the information is initially fragile and can be easily disrupted or lost, but over time the memory becomes more stable and resistant to interference or forgetting.

Question 20

Memory loss accompanying electroconvulsive shock probably occurs because

Accepted Answer

Electroconvulsive shock disrupts consolidation, which is the process of converting short-term memories into long-term memories. This disruption can lead to memory loss.
