This study was designed to determine the effects of retention interval (0, 4, 8, or 16 sec.), trials, and type of interpolated material (nothing, numbers, consonants, or CVCs) on STM. The results indicated that: (1) retention is inversely related to similarity of test and interpolated items, and (2) similarity interacts with both length of the retention interval and the number of practice trials.
