Objective rules of sequencing were applied to elementary level instructional material to determine their effect on time, errors made during instruction, and posttest errors. Results are discussed in terms of the application of the rules to various types of instructional material. (Author/BJG)

RESEARCH IS REPORTED HERE CONCERNING THE ASSUMPTION THAT ITEMS IN A LIST MUTUALLY AFFECT EACH OTHER IN VERBAL LIST-LEARNING. THE AUTHOR CONSIDERS BOTH THE MODE OF THE DATA ANALYSIS AND THE METHOD OF S-R (STIMULUS RESPONSE) PRESENTATION FOR A NUMBER OF RESTRICTED THEORETICAL ASSUMPTIONS INVOLVING ITEM INTERACTIONS IN S-R LIST-LEARNING EXPERIMENTS.…

This research on factors influencing verbal learning and retention has used new techniques, attacked new problems, and tested new theories while trying to keep the experiments systematic. Studies conducted involved (1) the effect of varying the length of the intertrial interval on the learning and retention of different types of learning tasks;…

Time-of-day effects on children's incidental visual memory for words and ability to solve verbal analogies were investigated. Thirty-six normal, learning disabled, and educable retarded children were assigned morning or afternoon learning/recall sessions. All showed afternoon superiority for superficially processed words, but no differences for…

This study investigated learning through listening at rates ranging from 78 to 428 words per minute (wpm). The sample consisted of 117 elementary school children, from two levels of intelligence. Immediate and one-week retention data were gathered on each subject. Results of the study indicate that listening rates of 228 and 278 wpm are more…
