Two experiments demonstrated interactive effects between locus of control and expectancy confirmation-disconfirmation in determining attribution of failure. (Editor)

Structural and semantic levels of processing were distinguished in two experiments that varied stimulus meaningfulness in an incidental learning paradigm. (Editor)

Attempts to establish the degree of perspective convergence, which the Western observer will accept as a realistic portrayal of objects drawn in perspective, and to determine the relationship between acceptable convergence and viewing conditions. (Author/RK)

Two experiments were designed to consider the effects of chronic high residential density on responses to choice and controllable and uncontrollable outcomes. (Editor)

Selected time components of the cardiac cycle were determined during breathing in air, breathing through a snorkel during face immersion, apnea in air, and apnea during face immersion. (PBS)

Two experiments were conducted to examine the effects of justice motivation and the presentation of the victim on the willingness of individuals to extend help to innocent victims. (Editor)

The two-process theory of detection, search, and attention presented by Schneider and Shiffrin (1977) is tested and extended in a series of experiments. The studies demonstrate the qualitative difference between two modes of information processing: automatic detection and controlled search. A general framework for human information processing is…

Reviews research related to laboratory work and makes recommendations for the classroom on how to make labs more meaningful. Argues that pre- and post-laboratory discussions containing theory behind the lab and purposes of the lab are essential for new understanding. (DDR)

Gives a step-by-step description of a problem-solving microscale chemistry laboratory to show how this implementation of problem-solving teaching can be put into practice. Pedagogical and practical issues are discussed. (DKM)

Compared effectiveness of vicarious and written training techniques to teach parents an early stimulation program for infants with Downs Syndrome. Found that infants whose parents were trained through observing a clinician stimulate their child had higher average developmental quotients in gross motor and language development between 6 and 24…

Describes the construction of a simple apparatus that can be used to take advantage of the overhead projector in a spectacular presentation of chemical reactions that complement quantitative approaches of study in the traditional high school science classroom. (JRH)

Offers 19 ideas based on learning styles to enhance student motivation. Includes tips for: conducting miniexperiments to identify peak learning times and conditions; varying teaching methods, mood, and pace; incorporating clear objectives, structured choices, relevant material, and humor; and keeping parents and students informed about learning…

Describes an approach that uses fiction as a springboard to environmental science experiments and discussions. (JRH)

Describes an experiment designed to determine ascorbic acid concentrations in natural orange juice. The experiment is used with undergraduate pharmacy students to allow understanding of the principles of operation of the coulometer and polarograph. (DDR)

Presents a laboratory investigation to demonstrate that habitat structure promotes increased organism abundance and species diversity by reducing predator effects on prey abundance. Investigates the effects of goldfish (Carassius auratus) predators on Gammarus sp. (an amphipod) and Daphnia magna (a cladoceran) prey in the absence and presence of a…
