Abstract

Previous research in short-term memory and working memory theories have long suggested average size limits on memory processes, from 7±2 and then to 4±1 individual pieces of information. Research into mnemonics and memory efficiency has looked for a way to further optimize the amount of individual raw data that can be stored, and arrived at between 3 and 4 as the most optimal chunks. This study used a between-groups study design with a digit span task in order to compare the success rate of participants memorizing a 15-digit number using the chunking mnemonic when told to use the optimal chunk size of 3 and when allowed to use their own, personally intuitive sizes. On average, participants using only chunks of 3 answered 1.73 more numbers correctly than the rest, with a significant effect. These findings may allow for improved interventions or training courses for mnemonics and working memory capacity, a metric associated with increased reading, language and attention skills.
