Reports on research showing that when an event, or a problem, is repeated, the processing of that event is not necessarily repeated. Instead, sometimes the solution is remembered, and this is shown to influence subsequent retention, as well as such tasks as word perception. (AM)

Attempts to analyze the effects of advance organizers on an environmental education unit, assess retention of the instructional material one year later, and determine if changes in perceptions of a woodland occurred. (GA)

Three treatments based on the model of memory proposed by R.M. Gagne and R.T. White were compared in their effects on eighth- and ninth-graders' learning and retention of geographical facts and skills. The first treatment had an active excursion, the second had a passive excursion, and the third had no excursion. (Author/PN)

Subjects who were preparing to teach scored reliably higher than controls on a subsequent retention test. In experiment 2, for both a verbal and a problem-solving task, subjects either worked alone, verbalized their thoughts or taught another person the task while performing. There were no reliable differences. (Author/CP)

An investigation of a saturation advertising campaign to acquaint the public with changes in radio wavelengths showed that repeated presentation of material does not lead to learning unless appropriate encoding occurs. Such encoding will occur when subjects are allowed to use previously acquired learning strategies. (PMJ)

A study examined the effects of pictorial and verbal illustrations on the initial learning and long term retention of written instruction. Subjects were eighth and ninth grade students randomly assigned to one of two text conditions (literal or analogous instructions) under one of four pictorial conditions (no picture, functional drawing,…

Two experiments were conducted to assess the effects of elaborated presentation on noun-pair retention. A 2 x 2 factorial design was used with aural-verbal presentation (standard versus elaborated) and visual-pictorial presentation (standard versus elaborated). Subjects for one experiment were 64 second-grade children from a Mexican-American…

The main objective of the Goteborg Project on Non-Verbatim Learning was to arrive at a commensurable description of the process and outcome of non-verbatim learning, also referred to as meaningful verbal learning. Such a description was thought to be a necessary presupposition for any explanatory models both in experiments on learning and in the…

The purpose of this study was to determine whether children as young as second-graders could encode categorically within an abstract evaluative dimension. The study uses mode of stimulus presentation (auditory or visual) as an independent variable. The subjects were 40 white middle class children from grades 2, 4, and 6, who were randomly assigned…

The effect of presentation time on learning under varying mediation instructions demonstrated a time-dependent difference in the facilitating effect of imagery generation or sentence generation instructions. Subjects were junior high school students working in a paired associate task with concrete nouns. Both cognitive strategies were more…

THIS SUPPLEMENTARY BIBLIOGRAPHY LISTS MATERIALS ON VARIOUS FACETS OF HUMAN LEARNING. APPROXIMATELY 60 UNANNOTATED REFERENCES ARE PROVIDED FOR DOCUMENTS DATING FROM 1954 TO 1966. JOURNAL ARTICLES, BOOKS, RESEARCH REPORTS, AND CONFERENCE PAPERS ARE LISTED. SOME SUBJECT AREAS INCLUDED ARE (1) LEARNING PARAMETERS AND ABILITY, (2) RETENTION AND…

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;…

Three classroom experiments were conducted using a simulation game, Trade and Develop, designed for classroom use with students in grade six through twelve economic geography classes. The hypotheses tested were: a simulation game will motivate students to learn subject matter related to the game, and, the game will facilitate learning by acting as…

A research project involving 16 experiments investigated the nature of the encoding process for verbal materials, particularly differences arising from mode of presentation. The results showed that a change in mode of presentation of items produced a recovery from interference in short term retention. Since intermodal interference was lower than…
