Eligibility criteria

Exclusion

Individuals who are not yet adults (infants, children, teenage children),
Adults unable to consent,
Adults with known impaired decision-making capacity,
Pregnant women,
Prisoners (or other detained/paroled individuals),
Students or postdoctoral trainees who are taught by or academically mentored by the Principal Investigator, in compliance with the Enrollment of Students and Trainees in Research Studies policies.
Non-fluent English speakers, Tests (specifically Scrambled Letters and QuickSIN) require proficiency in the English language.
Individuals with severe hearing impairment, Tests (specifically QuickSIN) require participants to not have trouble hearing speech.
Individuals with significant, uncorrected visual impairment. All visual tests require the participant to be able to read medium-sized text on a screen approximately two feet in front of them.

What this trial measures

  • SNR-loss (dB)baseline

    The Quick Sound-in-Noise (QuickSIN) test is a common method for assessing speech-in-noise perception. In this test, participants listen to sentences spoken by a female speaker in increasingly loud four-talker babble. The signal-to-noise ratio (SNR) loss for two QuickSIN tests will be averaged and recorded.

  • Audiogrambaseline

    Behavioral hearing threshold

  • Stroop timesbaseline

    The Stroop Test assesses inhibition-concentration. This test consists of two sets of subtests. Each subtest requires reading 25 words from a table of colored words: the first subtest requires the participant to read the word, and the second requires the participant to name the color of the word. In the first set of subtests, the words will be colored corresponding to the meaning of the color word (i.e. 'Red' will be colored red). In the second set of subtests, the words will be colored in a different color than the meaning of the word (i.e.' Red' will be colored purple). The completion time of each subtest will be recorded.

  • Trail timesbaseline

    The Trail-Making Test (TMT) assesses attention and processing speed. This test consists of subtests A and B. In part A, the participant must connect dots numbered 1-25 in numerical order. In part B, the participant must connect dots numbered 1-13 and dots labeled A-L in alternating order (i.e. 1-A-2-B). If the participant makes a mistake, they must correct the mistake before moving on. The completion time of each subtest will be recorded.

  • Percent identifiedbaseline

    The Scrambled Letters and VisualSNR tests were developed to assess the participant's ability to decipher garbled or distorted visual stimuli.
