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.

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)

Describes an experiment that illustrates the role of hydrogen bond formation in producing a heat of reaction when ethanol and water are mixed. (MLH)

Describes a laboratory procedure for identifying carbon-14 labelled acetic acid by first converting it to acetophenone, then oxidizing the labelled carboxyl with permanganate. (MLH)

Describes a method for determining the rate constants of enzyme reactions involving two substrates with the use of double reciprocal plots. (MLH)

Describes a procedure for performing an enzyme assay colorimetrically on tyrosinase obtained from fruits and vegetables. (MLH)

Presents the views of the chairman of the group of scientists that prepared the preliminary proposal on DNA guidelines for the 1975 Asilomar Conference. Examples and illustrations are used to argue that stronger and tighter controls than those outlined in the National Institutes of Health (NIH) guidelines are needed. (CS)

Describes an experiment involving gas-liquid chromatography of fatty acid methyl esters in petroleum ether solution. (MLH)
