“…Early experiments on the learning of connected discourse were performed by Henderson (1903) and Lyon (1917). The first full review of research literature in this area appears to have been the one by Welborn and English (1937), who were concerned mainly with the differences between what they called "verbatim" and "logical" learning. (Roughly, "verbatim" learning is learning of a discourse, i. e., its exact words, while "logical" learning is learning from a discourse, i.e., its content~d ideas.) Stroud (1940) touched on certain problems of MVD learnir.g in his review of research in school learning.…”
