Describes the laboratory procedure to be used for an effective demonstration of aldol condensation. (CP)

Ethylene hydrogenation on a platinum catalyst, electrolytically applied to a tube wall, is a good system for the study of the interactions between diffusion and surface reaction in heterogeneous catalysis. Theoretical background, apparatus, procedure, and student performance of this experiment are discussed. (BB)

Two experiments are reported which compared different forms of presentation of a perspective-taking task. The task required 4-year-old children to select pictures showing another person's view of an array similar to Piaget and Inhelder's mountains. (Editor)

This research was undertaken to determine the factor structure of the 26-item revised versions of the Mehrabian (1968) Female and Male scales, a self-report instrument designed to measure achievement motivation. (Author/RK)

Grant and Roberts found that houselight presented throughout the delay period on a delayed matching-to-sample task caused pigeons to demonstrate a much lower level of accuracy than was found when the delay was spent in darkness. A series of experiments was carried out to examine possible mechanisms responsible for this light-induced retroactive…

Argues for the importance of combining the concerns of the functionalist (Dewey, 1910) approach to memory with investigations of the effects of context and task demands. Two experiments are reported that demonstrate interactions between task demands and the more traditional functionalist variables. Particularly demonstrates that the effects of…

Three experiments were designed to clarify the perplexing ability of subjects to discriminate between to-be-remembered (T BR) and to-be-forgotten (TBF) items in memory. Results implicate within-list retrieval of TBR items as a potent tagging or strengthening operation that provides a basis on which those items may later be discriminated from TBF…

Reviews the chemistry of methylmercury, methylmercury poisoning, and its treatment. (SL)

Describes a laboratory experiment to analyze wine for its major components using a standard enological analytical procedure. (Author/GA)

Describes a safe and simple laboratory experiment to polymerise alkenes. Uses a two components catalyst; an unsolveted Grignard reagent and titanium (IV) chloride. (GA)

A phase catalyst approach to nucleophilic and electrophilic reactions is proposed. (CP)

The primary hypothesis examined was that people giving positive evaluations are themselves regarded as more attractive than when they give negative evaluations. Tests whether this holds when reciprocity is not at issue, the situation is realistic rather than role playing, and when there is no possibility of future interaction. (Editor/RK)

A simulation experiment for the dissolution kinetics of steroids is described whose goals are to demonstrate the characteristics of the physical-chemical model for dissolution and to relate the physical-chemical model to the potential therapeutic availability of the drug. Computational details are given. (LBH)

Describes a recording gas microvolumeter constructed to carry out sensitive studies of the kinetics of photodecomposition of water. (SL)

1,242 subjects, in five experiments plus a pilot study, saw a series of slides depicting a single auto-pedestrian accident. These experiments investigate how information supplied after an event influences a witness's memory for that event. Results suggest that information supplied a witness after an event, whether inconsistent or misleading, is…
