Change points or naturally occurring breaks in accelerated speech affect comprehension.
Navy Combat Information Center

This project consists of a series of human-subjects experiments that seek to examine the limits of human performance in complex Naval environments, such as the Combat Information Center (CIC). The studies focus on a promising Human-Computer Interaction (HCI) solution for the monitoring of multiple radio communication channels: the acceleration and serialization of radio traffic from concurrently active channels. Building on related work being conducted at NRL, a series of experiments are designed to determine to what extent the skill of attending to and understanding accelerated speech can be trained, and whether or not individual differences in memory and executive factors contribute to task performance in complex auditory domains. Experimental narratives are used in which messages have been broken down into clauses, and associated change points (or, natural breakpoints for the encoding of information) within the narrative have been identified. Training and recognition of accelerated speech information is studied in the context of existing work on event structure and perceptual saliency (i.e., situation models), in order to maximize how listeners might more naturally perceive, efficiently encode, and remember information.

This project is basic research funded by the Office of Naval Research Code 34. The pertinent funding documents are WX20879 and WX20420. The Principal Investigator on the project is Dr. Christina Wasylyshyn.
