33. Which of the following most accurately describes short-term memory?
Answer: C
An active memory that is used when holding information in an available state
Short-term memory is characterized as an active memory system that temporarily holds information for immediate use. It plays a crucial role in processing and manipulating information that is currently relevant.
A) A fleeting memory that records sensations that are immediately experienced
While this option reflects a component of sensory memory, it does not accurately describe short-term memory. Short-term memory involves more than just fleeting sensations; it actively engages with and processes information for a limited duration.
B) A permanent memory that retains information indefinitely
This option incorrectly describes long-term memory rather than short-term memory. Short-term memory is not designed for permanence, as it only holds information temporarily, typically for seconds to minutes, without the capacity for indefinite retention.
C) An active memory that is used when holding information in an available state
This is the correct description of short-term memory. It emphasizes the active role of short-term memory in maintaining information in an accessible state for tasks such as problem-solving and decision-making, highlighting its temporary yet crucial function.
D) An abundant memory that can retain large amounts of information
This option mischaracterizes short-term memory, as it is limited in capacity. Short-term memory typically holds a small amount of information, often described by Miller's law as approximately seven items, rather than being abundant.
Conclusion
The correct answer, describing short-term memory as an active memory used for holding information in an available state, aligns with its primary function in cognitive processes. In contrast, the other options either misrepresent the nature and duration of short-term memory or confuse it with other types of memory systems. Understanding the specific role of short-term memory is essential for grasping how we process and utilize information in everyday situations.
