EFFECTS OF THE MODE AND RATE OF TRANSMITTING MESSAGES UPON THE RELATIONSHIPS BETWEEN THEIR INTENSITY AND THE INTENSITY OF REPETITIONS OF THEM,

Abstract

An experiment was conducted with a view to determining the extent to which the relationship between intensities of original and repeated messages might be affected by (1) the mode of transmitting the originals and (2) syllabic rate of their transmission. Equally readable phrases - some read rapidly, some slowly, and some at an intermediate rate - were presented to each of a number of subjects (Ss) instructed to repeat each message in his usual way of speaking. Some messages were recorded, and the recorded versions were played through a loudspeaker or through headphones; some emanated directly from the lips of the reader. The intensity level of the messages was low for some Ss (Group I), moderate for others (Group II), and high for others (Group III). The average syllabic intensity of the repetitions of messages presented at one rate and over one transmission system was determined for each S. From these individual measures group means were computed for the various combinations of experimental conditions, and the differences among them were evaluated. (Author)
