Abstract
Twenty-eight first graders were taught letter-sound correspondences according to massed and spaced formats. One group received a spaced format on i and massed format on e, and the other received a spaced format on e, and massed format on J. A paired associated format required children to produce the appropriate sounds in response to visually presented letters (e, m, s, c, i). Compared to the massed format, correct responses to the letter presented according to the spaced format were more frequent on the posttest (72% versus 38%), though less frequent during training (56% versus 74%). The findings extended the superiority of spaced presentations to younger subjects and academically relevant stimuli.
