In this paper, Miller (1956) presents a theory of memory based on the idea that the human mind organizes and stores information in groups, or "chunks," rather than as individual items. He argues that the span of absolute judgment and the span of immediate memory impose limitations on the amount of information that can be received, processed, and remembered. To overcome these limitations, the mind organizes stimulus input simultaneously into several dimensions and successively into a sequence of chunks. Miller also proposes that the process of recoding, or organizing information into chunks, is a fundamental psychological process that deserves more explicit attention from clinicians, social psychologists, linguists, and anthropologists.Miller provides several examples of how the mind organizes information into chunks. For example, he notes that people tend to remember the seven-day week, the seven-point rating scale, and the seven categories for absolute judgment. He also suggests that imagery may be a form of recoding, with images forming chunks of information.In addition, Miller proposes that concepts and measures provided by the theory of information can provide a quantitative way of getting at questions related to learning and memory. He also notes that the idea of a "magical number seven" has been observed in various contexts, such as the seven wonders of the world, the seven seas, and the seven days of the week. However, he withholds judgment on whether this is a deep and profound phenomenon or simply a coincidence.Overall, Miller's theory of memory has had a significant impact on the field of psychology and has influenced research on learning, memory, and cognition. His ideas about recoding and the role of chunks in memory organization have been widely adopted and continue to be studied and refined today.
