As a step towards providing detailed, diagnostic data for teaching reading, a diagnostic test for two major letter-sound patterns was developed and tested on primary school children. (Authors)

The associations from phoneme to grapheme appeared to be considerably easier than the associations from grapheme to phoneme. (Authors)

Noise is controlled by the use of carpeting and soft surfaces, as well as by a special 2-level ceiling design. (Author)

A device which provides an inexpensive means for making precise studies of the kinetics of gas molecules is discussed. Two experiments are described: (1) Measurement of the vibrational relaxation time of gas molecules and (2) determination of intermolecular forces in molecules. (Author/DF)

Results supported the hypothesis that bilinguals would make more errors in English than native speakers, and that English unilinguals would err more on German than on English pentagrams. (Author)

Results of study indicate that vowel reduction is much more marked in English than in French, German or Spanish and that each one of the four languages offers a reduction pattern of its own. (Author/FWB)

Presents ways complex physics concepts can be demonstrated by music. Demonstrations and appropriate comments are provided for: (a) diffraction and interference, (b) standing waves in cavities and solids, (c) wave mechanics, (d) Fourier series, (e) propagation of waves in periodic media, and (f) group velocity.

Provides evidence indicating a strong connection between a high level of ambient household noise and intellectual deficits at stages of infant development. Observers rated noise level from all household sources (stereos, appliances, etc.). Delays were found in sensorimotor development with high levels of noise. (Author/JN)

Research findings are reported of a study (N=88 undergraduate males) of molar crowding in urban centers which involved the simultaneous variation of social density, spatial density, noise, and personality as they effect room affect (physical and psychological). Several main effects proved significant. (Author/DC)

Describes procedures for measuring the reverberation time in rooms which have been used for classroom demonstrations, and by nonscience students taking a course in musical acoustics. (Author/CS)

A study compared the effects of two different noise intensities on the cognitive performance of students. Findings indicated that at the higher noise intensity in the learning environment, performance on the reading comprehension task decreased. (LRA)
