We are testing a new system for linking grants to scientists.
The funding information displayed below comes from the
NIH Research Portfolio Online Reporting Tools and the
NSF Award Database.
The grant data on this page is limited to grants awarded in the United States and is thus partial. It can nonetheless be used to understand how funding patterns influence mentorship networks and vice-versa, which has deep implications on how research is done.

Speech Perception in Exceptional Cochlear Implant Users @ Arizona State University-Tempe Campus
DESCRIPTION (provided by applicant): The long-term objective of the proposed research is to understand how acoustic information can best be encoded for electrical stimulation in cochlear implant patients. The specific aim of this project is to determine the effects rate of stimulation, number of active intra-cochlear electrodes, and threshold mapping strategies on speech perception. Three experiments are proposed to examine these effects. First, comparisons between the three most current cochlear implant devices wilt be made by first matching users of each device on scores in optimal listening conditions and then comparing group performance on tests of speech understanding in difficult listening situations. A second study will evaluate the role of temporal resolution on speech understanding. Subjects will complete a set of experiments in which both output rate and the level of detail in the temporal envelope of speech are manipulated. Outcomes from this study will be used to determine the benefits of representing higher frequencies in the temporal envelope of each channel. The third experiment will assess differences in speech understanding when electrical thresholds are set by standard threshold testing, set to 10% of the maximum comfort level (MCL), and set to electrical values of zero.

To provide research support specifically limited in time and amount for studies in categorical program areas. Small grants provide flexibility for initiating studies which are generally for preliminary short-term projects and are non-renewable. |
Hearing and Stress @ Arizona State University-Tempe Campus
DESCRIPTION (provided by applicant): Hearing-impaired listeners commonly report feelings of anxiety, stress, and mental fatigue in response to communication demands in social settings. These concerns are typically documented using subjective reports and questionnaires. The goal of this project is to quantify the overall effort involved in speech perception as indicated by a physiological measure of stress. Preliminary studies indicate that heart rate variability, or the variability in timing between consecutive heart beats, can provide objective evidence of changes in effort required for understanding speech at various signal-to-noise ratios. This project will provide an objective measure of the effort required for hearing- impaired listeners to understand speech presented in noise in an unaided and aided condition. The outcomes will be compared to a cohort of age-matched, normal-hearing listeners. PUBLIC HEALTH RELEVANCE: Hearing-impaired listeners commonly report feelings of anxiety, stress, and mental fatigue in response to communication demands in social settings. These concerns are typically documented using subjective reports and questionnaires. The goal of this project is to provide an objective measure of the overall effort involved in speech perception as indicated by heart rate variability, a physiological measure of stress.
