Describes an undergraduate experiment in which Gantrez AN polymer chains are crosslinked at the anhydride groups by the addition of the hydroxyl groups of triethanolamine, which also acts as a basic catalyst. (MLH)

Describes an experiment in which metal compounds, such as anhydrous oxides, are placed into a glass tube which is heated until the metal colors the glass. (MLH)

Describes a study of the kinetics of the recombination of nitrogen atoms in which concentration-time relations are determined directly by utilizing visual observations of emissions to make gas phase titrations of N atoms with NO. (MLH)

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)

Attempts to evaluate the hypothesis that rats are more hesitant to ingest novel-flavored substances while they are under the influence of a toxic agent than in the normal state. (Author/RK)

Two experiments were conducted in order to investigate the relationship between memory for individual sentences and memory for the holisitic ideas conveyed by those sentences. (Editor)

Three experiments evaluated the effect of poststimulus distractor characteristics in altering recognition of random shapes. (Editor)

Three experiments are reported investigating whether the decreasing recall over trials in the Brown-Peterson paradigm--proactive inhibition (PI)--derives from encoding or storage (availability) differences between items or from retrieval (accessibility) differences. (Editor)

Lists materials and methods for an experiment that demonstrates the concept of glomerular filtration rate (GFR) using anesthesized dogs. In the dog, GFR is equivalent to the renal plasma clearance of exogenous creatinine. (CS)

Describes an experiment using rats that demonstrates contractile characteristics of normal and hypertrophied muscle. Compensatory hypertrophy of the plantaris muscle is induced by surgical removal of the synergistic gastrocnemium muscle. Includes methods for determination of contractile properties of normal and hypertrophied muscle and…

Previous research has investigated the effects of interpresentation lag within the context of experimenter-controlled lag values. The present study attempted to explore subject-controlled lag effects on paired-associate learning. (Editor)

Examines the effects of recall strategies on the serial position curve in immediate and delayed recall. (Author/RK)

The proposition that natural language concepts are represented as fuzzy sets, a generalization of the traditional theory of sets, of meaning components and that language operators--adverbs, negative markers, and adjectives--can be considered as operators on fuzzy sets was assessed empirically. (Editor/RK)

Two experiments attempted to directly assess the impact of self-other perspective on success and failure attributions for a variety of achievement-related situations. (Author/RK)

Two studies are reported which utilize a variety of achievement situations. It was hypothesized that subjects would spontaneously make attributions to ability, effort, luck and/or task difficulty in all these situations and that they would seek information of the types used in previous studies.
