Speech Perception With High Cognitive Demand

May 25, 2023 updated by: Joe Smith, University of Maryland, College Park

Pilot Study - Validation of Speech Materials for an Auditory-cognitive Training Paradigm (NIH P01 Project - Speech Perception With High Cognitive Demand)

With advancing age, adults experience increasing speech understanding difficulties in challenging situations. Currently, speech-in-noise difficulties are rehabilitated by providing hearing aids. For older normal-hearing adults, however, hearing devices do not provide much benefit since these adults do not have a decreased hearing sensitivity. The goal of the "Speech Perception with High Cognitive Demand" Project is to evaluate the benefit of a new auditory-cognitive training paradigm. In order to provide maximal benefit for older, normal-hearing adults, a validation of the new training materials is required. In a pilot study, the investigators will evaluate the new auditory-cognitive training paradigm in 15 young, normal-hearing adults (18-30 years). Based on these results, the training paradigm can be further optimized for older adults.

Detailed Description

With advancing age, adults experience increasing speech understanding difficulties in challenging situations, such as difficulty with understanding other persons in a noisy restaurant. Speech-in-noise difficulties are typically rehabilitated by providing hearing aids. For older normal-hearing adults, however, hearing devices do not provide much benefit since these adults do not have a decreased hearing sensitivity. For these adults communication difficulties persist in everyday life situations and can even lead to social withdrawal, isolation, and depression.

A growing body of studies demonstrates that combined auditory-cognitive training paradigms can offer speech-in-noise benefits to adults with hearing loss that could prevent the consequences listed above (Ferguson & Henshaw, 2015; Lawrence et al., 2018). The goal of the "Speech Perception with High Cognitive Demand" Project is to evaluate the benefit of a new auditory-cognitive training paradigm for older normal-hearing adults. The investigators developed an American English version of the Nottingham (UK) PLUS training paradigm in which listeners are asked to focus and listen to one speaker while ignoring another speaker. Although it cannot ensured that every participant will experience direct significant benefit from the training, the paradigm is being designed to optimally enhance the possibility of benefit: an adaptive procedure is employed in order to train each individual at their own level and to make the task challenging, and a short-term memory component is added to the original training paradigm to also enhance the cognitive skills of the participants. In addition, the training is implemented on tablets rather than computers, making at-home training possible (many older adults are more comfortable with tablets than laptops). This way, not only the risk of COVID-19 for participants is minimized, but training is also provided in a realistic setting which will ensure a better transfer of the trained skills to daily communication situations.

In order to provide maximal benefit for older, normal-hearing adults, a validation of the new training materials is however required, and the initial validation will be for younger adults only. The investigators will evaluate the translated and adjusted sentences (from UK to American English), the adaptive procedure, and the short-term memory component, in young, normal-hearing adults (18-30 years). Based on the results of this pilot study, the sentences and procedures of the training paradigm can be further optimized for older adults.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 30 years (Adult)

Accepts Healthy Volunteers

Yes

Experimental: Validation of auditory-cognitive training paradigm
In order to provide maximal speech-in-noise training benefit for older, normal-hearing adults, a validation of our new training materials is required. The investigators will evaluate the translated and adjusted sentences (based on the Nottingham UK PLUS training paradigm), the adaptive procedure, and the short-term memory component, in young, normal-hearing adults (18-30 years). Based on the results of this pilot study, the investigators can further optimize the sentences and procedures to be used during the training paradigm for older adults.
Behavioral: Auditory-cognitive training paradigm
The investigators developed an American English version of the Nottingham (UK) PLUS training paradigm in which listeners are asked to focus and listen to one speaker while ignoring another speaker. The paradigm is designed to optimally enhance the possibility of benefit: an adaptive procedure is employed in order to train each individual at their own level and to make the task challenging. A short-term memory component was also added to the original training paradigm, to enhance the cognitive skills of our participants. To provide maximal speech-in-noise benefit for older, normal-hearing adults, a validation of our new training materials is required. The investigators will evaluate this in young, normal-hearing adults (18-30 years) by studying our outcome measure (speech reception threshold) for the different sentence-scenarios and test-retest sessions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Speech reception threshold (SRT)
Time Frame: Through study completion, an average of 2 months
Sentences of seven different scenarios will be presented to young, normal-hearing adults. Participants will be instructed to listen to one speaker and ignore the other one, will be asked to recall the keywords of the to-be-attended sentence after the target sentence (0-back) or after the next sentence was presented (1-back; short-term memory component). The sentences will be presented using an 2 down-1up adaptive procedure in which the ratio of the levels of the to-be-attended and to-be-ignored speaker will be adjusted based on the correctly recalled keywords. This means that the procedure will converge to a level-ratio for which the participant understands 71% of the to-be-attended speaker, also called the speech reception threshold (SRT). The SRT will be used to compare the 0-back versus 1-back task and the validity of the different scenarios/sentences and procedures (mean/median SRT, inter- and intrasubject variability of the scenarios and test-retest session).
