Presents three experiments that explore whether inescapable shock of long duration and moderate intensity (LoShk) produces an avoidance-escape deficit (called an interference effect) by causing animals to learn to respond less actively or by causing them to learn to be "helpless". (Editor)

Several experiments tested the occurrence of the "Kamin effect", i.e., the deficit in performance of an incompletely learned avoidance task, in terms of discrimination (choice) behavior by rats. (Editor/RK)

Repeated, isolated presentations of a stimulus typically reduce the subsequent ability of that cue to become an effective conditioned stimulus. This phenomenon is known as the latent inhibition effect. Four experiments investigate this effect. (Editor/RK)

Memory for serial position was examined in two experiments, while a third study investigated the extent to which such information could be put to use. (Editor)

Investigates simple line drawings as they are represented in memory, attempts to validate a particular methodology which provides evidence about such representations, and proposes a theoretical algorithm that mechanically segments and assigns a psychological representation to a set of simple (nonsense) line drawings. (Author/RK)

Considers whether any sort of orthographic mechanism is used by fluent readers. (Author/RK)

Attempts to reexamine the role of response suppression as a contributor to retroactive inhibition in recall. (Author/RK)

The results of three studies clearly indicate that ongoing behavior is organized into perceptual units, and that these units may be validly identified by the Newtson (1973) unit marking procedure. (Author)

When a person acts bizarre, out of role, or in other extreme ways, the perceiver often attributes to that person an extreme disposition, and the attribution is made with confidence. Two experiments were conducted to investigate a modification of this analysis of attribution (Jones & Davis, 1965). (Author/RK)

Two initial experiments demonstrated that direction aftereffects of potentiation in the extraocular muscles (induced through sustained versional rotation to the side) generally increase as a function of the magnitude and duration of the inducing ocular rotation and can be built up under conditions of varied as well as constant fixation. (Editor)

This research sought to distinguish among three concepts of visual persistence by substituting the physical presence of the target stimulus while simultaneously inhibiting the formation of a persisting representation. Reportability of information about the stimuli was compared to a condition in which visual persistence was allowed to fully develop…

Describes high school physics laboratory experiments that use lasers to show that a diffraction pattern is a Fourier analysis of the slit function. (MLH)

Discusses a special topics biochemistry course that uses membrance phenomena to illustrate the interplay of many physical chemistry principles. (MLH)

Describes a laboratory experiment that uses a programmable calculator and the concepts of activity and activity coefficients to examine the effect of ionic strength on equilibrium constants. (LH)
