Relationships between oral sensory feedback skills and adaptation to delayed auditory feedback

The relationship between adaptation to delayed auditory feedback (DAF) and oral sensory feedback as measured by tasks of oral form discrimination (OFD) was investigated. In addition, the interactions between OFD ability and attempts to heighten subjects' awareness of oral feedback while speaking under DAF conditions by giving instruction to subjects as well as the condition of instruction itself were studied with adaptation to DAF as the dependent variable. Analyses of the data indicated a relationship between OFD ability and adaptation to DAF and an interaction between OFD ability and instruction. The study's rationale and results are discussed within the context of servosystem theory.
