“…In terms of rough "face validity," Jensen's findings might not have strong implications for instruction because his task-remembering a string of digits for a few seconds-does not resemble ordinary classroom learning. More to the point, research indicates that individual differences in short-term memory are at best modestly related to individual differences in list learning (Gorfein, Bennett, Arbak, & Graves, 1969;Gorfein & Blair, 1971). Consequently, Jensen's findings leave open the question of whether individual differences are as predictable across modalities as within modalities when the task involves learning larger amounts of material and retention over intervals longer than a few seconds.…”
