Photographs tell a story and illustrate an experience more profoundly than words alone. Real-time, text-based communication is an increasingly normal part of daily life as mobile devices and social networks proliferate. Yet, in the steady stream of tweets, comments, status updates, notifications, and e-mail, the details are easily lost in the…

Investigates the differences between rehearsal span and memory span and evaluates the research of Dalrymple-Alford (1967) on the part of rehearsal on reinforcing memory traces. (Author/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…

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

Revised version of a paper given at the 1972 International Conference on Speech Communication and Processing, Boston, Mass. (DD)

In three experiments the location of pigeons was monitored during 20-second illuminations of a right or left key presented in various temporal relationships with food delivery. In general, subjects approached a signal positively correlated with food and withdrew from a signal negatively correlated with food. (Editor)

Subjects responded to pairs of test items from learned linear orderings (e.g., Tom is taller than Dick; Dick is taller than Sam, etc.). Results are compared with previous studies of ordered linguistic, perceptual, and numerical information. (Editor/RK)

Separation thresholds for groups of 26 dyslexic and normal children attending the first year of secondary school were obtained with pairs of identically-oriented and spatially-overlapping straight lines presented at orientations varying from zero to 90 degrees. (Editor)

Three experiments are reported that were designed to delineate the properties of the stimulus encoding stage in reaction time tasks of varying stimulus-response compatibility. (Editor)

Attempts to replicate Gogel's (1972) observations with points of light and examines in addition whether the same results would be obtained if the binocularly nearer object was made visually more massive than the farther object and if the residual oculomotor cues were varied to produce different values of the reference distance.

The main finding of these four experiments was that the strong conditioning produced by a brief exposure to a truly random control weakened with prolonged exposure. (Author/RK)
