Which of the following best defines short-term memory?

• A. It is consciously activated with limited capacity
• B. It stores unlimited amounts of information
• C. It is identical to long-term memory
• D. It has no relevance to daily tasks

Answer: (A)

Short-term memory is the part of memory you actively hold in your mind and work with in the moment. It is consciously activated, meaning you deliberately focus on and manipulate the information there. It also has limited capacity, often described as around seven items (though this can vary with chunking). Information stays for only a short time unless you rehearse or refresh it. This differs from long-term memory, which stores vast amounts of information for longer periods and isn’t part of your current conscious focus. Short-term memory is essential for daily tasks like dialing a number, following a brief set of directions, or holding a thought while you problem-solve. The idea of unlimited storage describes long-term memory, and being identical to long-term memory ignores the distinct roles and durations. It also isn’t accurate to say it has no relevance to daily tasks, since everyday activities rely on actively holding and manipulating information in the short term.
