Which term identifies the capacity range for short-term memory?

The correct choice identifies a well-established principle in cognitive psychology regarding the capacity of short-term memory. Research by George A. Miller in 1956, often referred to as "Miller's Law," suggests that the average number of items an individual can hold in their short-term memory is approximately seven, plus or minus two. This finding indicates a typical range of about five to nine items but most commonly centers around seven.

Understanding this range helps to explain how we process and retain information in our short-term memory. For practical applications, it means that when trying to memorize a list or sequence, it's beneficial to keep the number of items limited to within this capacity range to enhance recall. Thus, the choice indicating 5-7 items reflects this empirical range and aligns with established psychological theories regarding memory capacity.

This understanding lays a foundation for further discussion about memory strategies, such as chunking, which can help increase the effective capacity of short-term memory beyond the typical limits by combining smaller units of information into larger, manageable "chunks."
