What is the capacity of short-term memory?

  1. 7 +/- 2 items

  2. 10 +/- 2 items

  3. 15 +/- 2 items

  4. 20 +/- 2 items


Correct Option: A
Explanation:

The capacity of short-term memory is limited to about 7 +/- 2 items. This means that we can hold about 7 items in short-term memory at any one time.

What is the duration of short-term memory?

  1. A few seconds

  2. A few minutes

  3. A few hours

  4. A few days


Correct Option: A
Explanation:

The duration of short-term memory is typically a few seconds. If information is not rehearsed or attended to, it will be forgotten within a few seconds.

What is the function of short-term memory?

  1. To store information that is currently being processed

  2. To store information that is needed for immediate use

  3. To store information that is important

  4. To store information that is interesting


Correct Option: A
Explanation:

The function of short-term memory is to store information that is currently being processed or that is needed for immediate use. This information is typically forgotten within a few seconds if it is not rehearsed or attended to.

What are some factors that can affect short-term memory?

  1. Stress

  2. Fatigue

  3. Alcohol consumption

  4. All of the above


Correct Option: D
Explanation:

Stress, fatigue, and alcohol consumption can all negatively affect short-term memory. Stress and fatigue can make it difficult to concentrate and attend to information, while alcohol consumption can impair memory consolidation.

What are some strategies for improving short-term memory?

  1. Rehearsal

  2. Organization

  3. Chunking

  4. All of the above


Correct Option: D
Explanation:

Rehearsal, organization, and chunking are all effective strategies for improving short-term memory. Rehearsal involves repeating information to yourself, organization involves grouping information into meaningful categories, and chunking involves breaking down information into smaller, more manageable units.

What is the difference between short-term memory and long-term memory?

  1. Short-term memory stores information for a brief period of time, while long-term memory stores information for a long period of time.

  2. Short-term memory stores information that is currently being processed, while long-term memory stores information that is not currently being processed.

  3. Short-term memory has a limited capacity, while long-term memory has an unlimited capacity.

  4. All of the above


Correct Option: D
Explanation:

Short-term memory stores information for a brief period of time, while long-term memory stores information for a long period of time. Short-term memory stores information that is currently being processed, while long-term memory stores information that is not currently being processed. Short-term memory has a limited capacity, while long-term memory has an unlimited capacity.

What is the role of the hippocampus in short-term memory?

  1. The hippocampus is involved in the formation of new memories.

  2. The hippocampus is involved in the consolidation of memories.

  3. The hippocampus is involved in the retrieval of memories.

  4. All of the above


Correct Option: D
Explanation:

The hippocampus is involved in the formation, consolidation, and retrieval of memories. It is a critical structure for short-term memory.

What is the role of the prefrontal cortex in short-term memory?

  1. The prefrontal cortex is involved in the working memory.

  2. The prefrontal cortex is involved in the attention.

  3. The prefrontal cortex is involved in the decision-making.

  4. All of the above


Correct Option: D
Explanation:

The prefrontal cortex is involved in the working memory, attention, and decision-making. It is a critical structure for short-term memory.

What is the difference between working memory and short-term memory?

  1. Working memory is a subset of short-term memory.

  2. Working memory is a type of long-term memory.

  3. Working memory is a type of implicit memory.

  4. None of the above


Correct Option: A
Explanation:

Working memory is a subset of short-term memory that is used to hold and manipulate information that is currently being processed. It is a limited-capacity system that can hold about 7 +/- 2 items for a brief period of time.

What are some disorders that can affect short-term memory?

  1. Alzheimer's disease

  2. Parkinson's disease

  3. Huntington's disease

  4. All of the above


Correct Option: D
Explanation:

Alzheimer's disease, Parkinson's disease, and Huntington's disease are all neurodegenerative disorders that can affect short-term memory. These disorders can damage the brain structures that are involved in short-term memory, such as the hippocampus and the prefrontal cortex.

What are some treatments for disorders that affect short-term memory?

  1. Medication

  2. Therapy

  3. Lifestyle changes

  4. All of the above


Correct Option: D
Explanation:

There is no cure for disorders that affect short-term memory, but there are treatments that can help to improve symptoms. These treatments may include medication, therapy, and lifestyle changes.

What is the difference between short-term memory and long-term memory?

  1. Short-term memory stores information for a brief period of time, while long-term memory stores information for a long period of time.

  2. Short-term memory stores information that is currently being processed, while long-term memory stores information that is not currently being processed.

  3. Short-term memory has a limited capacity, while long-term memory has an unlimited capacity.

  4. All of the above


Correct Option: D
Explanation:

Short-term memory stores information for a brief period of time, while long-term memory stores information for a long period of time. Short-term memory stores information that is currently being processed, while long-term memory stores information that is not currently being processed. Short-term memory has a limited capacity, while long-term memory has an unlimited capacity.
