Purpose of the study was to investigate further the nature of an imagery dimension as it relates to the storage of individual, object-referent words. (Authors)

It was hypothesized that individuals who can easily detect differences in the timbre of tone would be more likely to appreciate musical instruments with more complex sound waves, and that the degree of this tendency would be directly proportional to the length of time one has played the instrument.

Experiments are designed with application to phenomena of the real world for use in a third-quarter introductory college physics course in wave motion, sound, and light. The computer is used to process and analyze experimental data and to extend experimental observations through simulation. (Author/TS)
