Miller's proposal regarding the capacity of working memory is famously encapsulated in the concept often summarized as "the magical number seven, plus or minus two." This means that, on average, individuals can hold approximately seven distinct pieces of information in their working memory at one time, with some variability allowing for a range typically between five and nine items.

This framework has been influential in cognitive psychology as it highlights the limitations of our short-term memory processing capacity. Understanding this capacity can help in various practical applications, such as learning strategies, memory enhancement techniques, and understanding cognitive load during tasks.

While other options reflect different numerical values, they do not align with Miller's established findings, which emphasizes the robust nature of seven as a benchmark for working memory capacity.
