“Primary memory”: The effects of redundancy upon digit repetition

  • Kent M. Dallett
Human Learning and Thinking


Ss tried to repeat series of 8 digits immediately after hearing them. Each series of digits had a predictable digit (a zero) in a known location, and Ss were told to omit this digit. Performance in this task is similar to the performance obtained in repetition of 8 non-redundant digits, although if the redundant element is near the center of the series, Ss can improve their recall of the other digits. Digit recall seems to be largely, but not entirely, a matter of “primary memory,” which involves a more or less faithful unrecoded replica of stimulus input.
