Describes the theory, apparatus, and procedure for an experiment that measures the bimolecular quenching constant for the deactivation of an excited ruthenium ion complex using dissolved oxygen. (MLH)

Describes an experiment in which the reaction rate and equilibrium constant are obtained for the fumarase-catalyzed interconversion of fumaric acid and L-malic acid. (MLH)

Reports on a series of four experiments designed to study the importance of the variables of task structure and method of expectancy inducement in effecting systematic observer bias. (Author/RK)

In a series of three experiments on the role of memory in solving attribute-identification problems, the subjects did or did not have to remember their response and/or the stimulus for processing during any given intertrial interval. (Editor)

Investigates the relative importance that the eyes and mouth play in the representation in memory of a human face. Systematically applies two kinds of transformation--masking the eyes or the mouths on photographs of faces--and observes the effects on recognition. (Author/RK)

Predictions from a dual criterion model for old-new and right-wrong decisions about individual items following a multiple-item study phase were tested with bilingual items and quasi-bilingual subjects. (Editor)

Two experiments were run to test memory for the negation morpheme "not" in coordinate sentences (e.g., The ballerina had twins and the policewoman did not have triplets) and complex sentences (e.g., The ghost scared Hamlet into not murdering Shakespeare). (Editor)

There is a conflict in the literature on selective attention. Five experiments were conducted to resolve this conflict, and all involved a comparison of tachistoscopic recognition when alternatives were either presented beforehand or not. (Editor/RK)

Attempts to settle the question of whether reading units are ever larger than letters and considers the variables expected to influence the size of the reading unit. (Author/RK)

Reports some additional research that may resolve questions about the meanings accessed in recognizing ambiguous words. (Author/RK)

New media, i.e., motion pictures developed for educational purposes and educational television, are basic in that they so dominate the experiences of the child. Teachers must devise strategies for using the moving image as an active agent in learning and for encouraging the child to be an active agent in seeing. (Author/RK)

Describes an undergraduate chemistry laboratory experiment involving the production of phenol from benzene with the intermediate production of isopropylbenzene and isopropylbenzene hydroperoxide. (SL)

The present study casts doubt on (1) the validity of assuming certain geometric illusions as being "perspective" related, and (2) the consistency of perspective explanation (constancy scaling) for geometric illusions. (Author)

Demonstrates that preexposure to uncorrelated presentations of noises and shocks when rats are not permitted to respond interferes with the acquisition of both conditioned emotional response and signaled punishment suppression. (Author/RK)

A strong test of exposure effects was made by eliminating confounding demand characteristics through the use of a between-subject design. Each subject viewed novel stimuli at a single frequency level, and then rated them on several affective scales. (Editor)
