What is capacity in psychological terms?

In psychological terms, capacity refers to the quantity that can be stored or retained in the mind. This concept is often discussed in the context of memory, where capacity relates to how much information can be held and processed at one time. For example, the capacity of short-term memory is frequently cited as being able to hold about seven pieces of information, plus or minus two. This understanding of capacity is essential when examining cognitive abilities, learning processes, and the limits of human information processing.

The other options describe aspects of psychological function, like effort or emotional potential, but they do not encapsulate the notion of capacity as it pertains to the storage and retention of information. Therefore, referring to capacity as the quantity that can be stored provides a clear and accurate understanding of the term within psychology.
