Which of the following most accurately describes short-term memory?

Rationale

An active memory that is used when holding information in an available state.

Short-term memory is characterized by its ability to temporarily hold and manipulate information that is currently being used or processed. This system allows individuals to retain information for brief periods, typically ranging from seconds to a few minutes, while it is actively engaged.

A (A fleeting memory that records sensations that are immediately experienced) YOUR ANSWER

This description refers more to sensory memory, which captures fleeting sensory impressions for a very short duration. Unlike short-term memory, sensory memory does not involve active processing or manipulation of information, but rather the immediate recording of sensory experiences before they fade.

B (A permanent memory that retains information indefinitely) YOUR ANSWER

This choice incorrectly defines long-term memory, which is responsible for storing information over extended periods, often for a lifetime. Short-term memory, by contrast, is inherently temporary and does not retain information indefinitely.

C (An active memory that is used when holding information in an available state) CORRECT

This accurately describes short-term memory, as it functions to actively store and manage information that is currently in use. This memory system allows for immediate recall and manipulation of data, which is essential for tasks like problem-solving and reasoning.

D (An abundant memory that can retain large amounts of information) YOUR ANSWER

This statement misrepresents the capacity of short-term memory, which is limited in terms of the amount of information it can hold. Typically, short-term memory can retain approximately 7±2 items, making it less abundant compared to long-term memory, which can store vast quantities of information.

Conclusion

Short-term memory is defined as an active system that temporarily holds information for immediate use, allowing individuals to retrieve and manipulate data as needed. It is distinct from both sensory and long-term memory in its capacity and duration, emphasizing its role in cognitive processes such as reasoning and problem-solving. Understanding this distinction is crucial for comprehending how information is processed and utilized in everyday situations.
