Abstract : A single subject was able to increase his digit span from 7 digits to 80 digits with about 250 hours of practice. Verbal protocols and various experimental procedures were used to analyze the cognitive processes underlying the acquisition of this skill, and a computer simulation model of the skill was developed and tested. The two essential components of the skill were a mnemonic system for coding digit groups into meaningful units, and a retrieval structure for retrieving these units from long-term memory. The theoretical implications of our research are discussed in terms of three principles of skilled memory. (Author)
