Question 1

Short-term memories appear to be stored in the __________.

Accepted Answer

Short-term memories are primarily stored in the prefrontal lobes of the brain, specifically in the dorsolateral prefrontal cortex. These areas are responsible for working memory, which allows us to hold and manipulate information temporarily in our minds. Other brain regions, such as the hippocampus and parietal lobes, may also be involved in the storage and retrieval of short-term memories.

Question 2

Forgetting in long-term memory is most likely due to __________.

Accepted Answer

Interference from other information is a primary reason for forgetting in long-term memory, as new or similar information can disrupt the retrieval of previously stored information.

Question 3

Evidence suggests that nondeclarative memories are stored in which part of the brain?

Accepted Answer

Research has shown that nondeclarative memories, such as motor skills and classical conditioning, are stored in the cerebellum.

Question 4

Taamir is getting ready for an exam in his biology class tomorrow. He has not studied yet, and he is preparing all sorts of caffeinated beverages to help him pull an "all-nighter." In memory terms, Taamir is about to engage in __________ practice.

Accepted Answer

Massed practice involves cramming and attempting to learn large amounts of material in a short period of time, often with the use of caffeine or other stimulants. This type of practice is generally less effective for long-term retention of information compared to distributed practice, which involves spreading out study sessions over a longer period of time.

Question 5

Kyra took psychology in the fall semester and is now taking sociology. Several of the concepts are similar, and Kyra finds that she sometimes has trouble recalling some of the major psychological theorists. She keeps getting them confused with sociological theorists. Kyra's problem is most likely due to __________.

Accepted Answer

Retroactive interference occurs when new information interferes with the ability to recall older information. In Kyra's case, the new sociology concepts are interfering with her ability to recall the psychological theorists she learned previously.

Question 6

Maeve has two exams today. One is in French and the other is in history. Last night she studied French before history. When she gets to her French test, all she can remember is history! Maeve's memory is suffering from __________.

Accepted Answer

Retroactive interference occurs when newly learned information interferes with the ability to recall previously learned information. In this case, Maeve studied history after French, and the information she learned in history interfered with her ability to recall information from her French study session.

Question 7

A psychologist asks people to recall the name of their kindergarten teacher. Surprisingly, the majority of people correctly do this and comment, "Gee whiz, I haven't thought about that old bat [or old coot] in years!" Their ability to remember their teacher's name tends to conflict with which theory of forgetting?

Accepted Answer

The ability of people to recall their kindergarten teacher's name after many years, despite not having thought about them, conflicts with the decay or disuse theory. This theory suggests that memories fade or are lost over time simply because they are not used, which doesn't seem to apply in this scenario where the memory remains accessible after a long period of disuse.

Question 8

Maeve has two exams today. One is in French and the other is in history. Last night she studied French before history. When she gets to her history test, all she can remember is French! Maeve's memory is suffering from __________.

Accepted Answer

Maeve's inability to remember information from her history exam is due to proactive interference, which occurs when previously learned information interferes with the ability to remember new information. In this case, her study of French may have interfered with her ability to remember information from her history exam.

Question 9

When newer information interferes with the retrieval of older information, this is called __________.

Accepted Answer

Retroactive interference occurs when new information interferes with the recall of older information. This can happen when learning new information that is similar to previously learned information, causing the older information to become harder to retrieve.

Question 10

Decay theory works well to explain forgetting in __________.

Accepted Answer

Decay theory suggests that memory fades due to the mere passage of time. It is most applicable to sensory and short-term memory, where information can be lost if not rehearsed or encoded into long-term memory.

Question 11

Retroactive interference, as used in the study of memory, refers to __________.

Accepted Answer

Retroactive interference occurs when newly learned information interferes with the retrieval of older information. This often happens when similar information is learned and the brain gets confused about what information to retrieve.

Question 12

You are invited to take part in a study by a researcher trying to replicate the work of Hermann Ebbinghaus. What might this researcher ask you to do?

Accepted Answer

Hermann Ebbinghaus is most well-known for his work on memory and forgetting, specifically his research on memorizing nonsensical syllables. Choice C involves the participant listening to a list of nonsensical syllables and then repeating them back, which replicates Ebbinghaus's research. Choices A, B, and D do not necessarily involve memorization of nonsensical syllables or Ebbinghaus's specific research.

Question 13

You start out using Firefox, then change to Explorer because your company demands that browsers be Microsoft products. If you have trouble using Explorer, it is most likely due to __________.

Accepted Answer

Proactive interference occurs when old information interferes with the ability to learn new information. In this case, your previous experience with Firefox may interfere with your ability to use Explorer effectively.

Question 14

Which of the following statements regarding memory storage in the brain is TRUE?

Accepted Answer

Research has shown that different parts of the brain are specialized for the storage of different types of memories. For example, the hippocampus is involved in the formation and storage of new declarative memories (facts and events), while the cerebellum is involved in the formation and storage of procedural memories (skills and habits). Additionally, studies have shown that memories are not randomly distributed throughout the brain, but are rather organized into networks of neurons that encode and retrieve specific information.

Question 15

The practice of spacing out the study of material to be remembered by including breaks between study periods is called __________ practice.

Accepted Answer

Distributed practice refers to the practice of spacing out the study of material to be remembered by including breaks between study periods. This has been found to be more effective than massed practice, which involves studying for an extended period of time without breaks. Neither A, B, nor D accurately describe this practice.

Question 16

Most people have difficulty actually recognizing the correct image of the Lincoln penny. The most likely cause of this problem is __________.

Accepted Answer

Encoding failure refers to the inability to properly process and store information into memory. In the case of recognizing the correct image of the Lincoln penny, if the encoding process was not effective, then the image may not have been stored properly in memory, making it difficult to retrieve and recognize later on.

Question 17

Imagine that the first car you learned to drive was a manual transmission with a clutch, but the car you drive now is an automatic. Sometimes you find yourself reaching for the clutch that is no longer there. This example illustrates __________.

Accepted Answer

This example illustrates proactive interference, where old memories interfere with the recall of new memories. In this case, the habit of reaching for a clutch (old memory) interferes with the operation of an automatic car (new memory).

Question 18

__________ is the tendency for older or previously learned material to interfere with the retrieval of newer, more recently learned material.

Accepted Answer

Proactive interference occurs when previously learned material interferes with the retrieval of new material. This can happen when similar information is learned and stored in memory, and then the new material becomes harder to remember.

Question 19

Proactive interference, as used in the study of memory, refers to __________.

Accepted Answer

Proactive interference occurs when older information in memory makes it more difficult to learn and remember new information. This is because the old information interferes with the new information being retrieved or encoded.

Question 20

Evidence suggests that short-term memories are stored in which part of the brain?

Accepted Answer

Short-term memories are primarily processed and stored in the prefrontal lobes of the cortex, which are responsible for working memory and short-term retention of information. The cerebellum is largely involved in motor learning and coordination, while the hippocampus and amygdala are more involved in long-term memory formation and emotional processing, respectively.
