Reports and summarizes some of the findings of a conference, held in Oxford in July 1978, to discuss the role of the laboratory in physics education. (GA)

The gravimetric determination of calcium as calcium carbonate is described. This experiment is suitable for undergraduate quantitative analysis laboratories. It is less expensive than determination of chloride as silver chloride. (BB)

This demonstration uses the electrophoresis of indicators to demonstrate the principles involved in the separation of isoenzymes. (BB)

Describes the controversy over the hidden variable in quantum mechanics, especially over Bohm's theory, and the criticism and rejection it received as a result of the erroneous application of Von Neumann's impossibility proof, rather than Bohn's theory itself. Concludes that science, especially physics, is not permeated by social factors. (GA)

Describes an experiment to characterize the enzyme polyphenol oxidase. Includes Purpose, Reagents and Equipment, Procedure, Extraction, Treatment of Data, and Discussion. (MA)

Presents the use of a Michelson interferometer in studies of visible spectroscopy. Discusses the experimental setup for obtaining reflectivity spectra of various semiconducting materials. (MLH)

Describes an experiment in which Fresnel diffraction patterns were observed with a beam of slow neutrons of wavelength 4.33 Angstroms. (MLH)

Describes an experiment that utilizes fluorescence intensity measurements from a Spectronic 20 to determine the rate constant for the fluorescence quenching of various aromatic hydrocarbons by carbon tetrachloride in an ethanol solvent. (MLH)

Explores the possibility that measurable individual differences in hypnotic susceptibility or the ability to attend selectively to informational cues may account for a portion of the variability found in several types of geometrical visual illusions. (Author/RK)

Examines whether self-consciousness, a personality disposition, affects self-attributions and attempts to replicate the research findings of Duval and Wicklund (1973) that self-awareness affects self-attributions. (Author/RK)

Three reaction time (RT) experiments using a modified Strenberg procedure were conducted to determine the number of memory representations maintained for perceptual (dot-pattern) concepts. (Editor)

In the first of two experiments investigating the inhibitory effect of cuing, the taxonomic frequencies of cue words and critical words were manipulated orthogonally. (Editor)

A list discrimination paradigm was used to examine the effects of orienting tasks upon the later temporal discrimination of words. The orienting task involved judgments about the relatedness of the words in a list to some concept. (Editor)

Two experiments are described which are concerned with the development of referebtial ability in children. (Editor)

Recent work by Hamill (1976) suggests that placement of monosyllabic content words in grammatical strings is correlated with the rhythmic pattern of the string. Using classic paradigms, this research shows that rhythmic organization is also evident in speech material without grammatical structure or the content word/function word distinction.…
