Presents and expands upon a seven-step model that is used to identify factors that bear consideration in the development of audiovisual materials for presentations. (JD)

Suggests the use of a chart to help students learn to use apostrophes correctly. (TJ)

Illustrates how expected mean squares needed in the analysis of variance can be arrived at via the use of only one rule: the expected mean square E(MS) for any source of variation for any ANOVA model is specified effect plus the specified effect in combination with any random effect. (Editor/RK)

Aims at providing data for evaluating the proposition that associations between exteroceptive (outside) stimuli and illness play a role in determining the effect of unconditioned stimulus preexposure on subsequent taste aversion conditioning. (Author/RK)

Discusses four experiments concerned with environmental determiners of the taste familiarity effect. Specifically, external environmental stimulation experienced by the subject at the time of taste preexposure and taste conditioning was varied in order to assess its influence on taste aversion learning. (Author/RK)

This study is the first demonstration of sequential contrast effects with human subjects during the acquisition of a discrimination without errors. Results are discussed in terms of Terrace's theory of errorless learning. (Editor/RK)

Describes a series of experiments showing that in normal subjects (a) iconic storage occurs primarily in the retina in the photoreceptors and (b) under conditions of dark pre- and postexposure fields, the icon is mainly a rod phenomenon. Draws conclusions based on these experiments, discusses previous work done by others, and attempts to reconcile…

Uses new approaches to differentiate three types of models describing intuitive numerical prediction. (Author)

Two sets of measurements evaluated performance on typographically inverted text that students had learned to read 13 to 15 months earlier. (Editor)
