MASSED VERSUS DISTRIBUTED PRACTICE IN LEARNED IMPROVEMENT OF SPEECH INTELLIGIBILITY

Student pilots or new air traffic controllers have two ways to learn to understand the noisy and distorted communications common to aircraft operations: they may learn as they are working on other aspects of the activity, or they may learn by devoting a continuous period of time to speech-intelligibility improvement. Work completed at this laboratory indicates that two listening sessions of less than 1 hour each can accomplish the improvement and, under some circumstances, a single session will do. The current experiments are intended to reveal some of the microstructure of this learning process.
