Speech-in-noise Perception in Autism and Fragile X

This study is looking for 60 participants, aged 15 to 35, with Autism Spectrum Disorder or Fragile X Syndrome, as well as typically developing individuals. The goal is to understand how the brain processes speech when there's background noise, and if visual cues can help. You'll have your brain activity recorded while listening to different speech sounds (like "ba" versus "da") and completing hearing tasks. Researchers will also compare your ability to understand numbers spoken in noise, both with and without visual help. To join, you need normal hearing and vision, no history of premature birth, and English as your first language. The study is currently recruiting participants.

Study design
This interventional study plans to enroll 60 participants, divided into three groups of 20 each (autism, Fragile X Syndrome, and typically developing individuals).
What's involved
You will complete hearing tests, cognitive and behavioral measures, questionnaires, and both passive and active hearing tasks while your brain activity is recorded with a neuroimaging cap.
Compensation
Not stated in the trial record.
Follow-up
Primary endpoints are measured at Baseline, so no long-term follow-up is specified.

Eligibility criteria

Exclusion

Hearing loss or uncorrected vision loss
history of premature birth (prior to 36 weeks gestation)
  • Speech reception threshold for single digits in noise- auditory onlyBaseline

    The SRT is the ratio between the loudness of speech and the loudness of background noise in decibels at which a participant can correctly report the digit that is presented at 50% accuracy.

  • Speech reception threshold for single digits in noise- with visual stimuliBaseline

    The SRT is the ratio between the loudness of speech and the loudness of background noise in decibels at which a participant can correctly report the digit that is presented at 50% accuracy. A higher SRT indicates more difficulty hearing speech in background noise

  • Scaled score for auditory attention subtestBaseline

    This task is from the Woodcock Johnson III. In this task, participants point to a picture after hearing a word presented in background noise, and accuracy is compared to same-age norms. Scores range from 1-19, with higher scores indicating better accuracy.

  • correlation between neural activation to speech (fNIRS) and neural differentiation of speech-in-noise (ERP)Baseline

    Percent change in oxygenation in auditory cortex while hearing speech alone will be correlated with amplitude of the mismatch negativity to deviant sounds. This correlation reflects how neural activation affects neural differentiation for each individual participant

  • correlation between neural activation to background noise (fNIRS) and neural differentiation of speech-in-noise (ERP)Baseline

    Percent change in oxygenation in auditory cortex while hearing background noise will be correlated with amplitude of the mismatch negativity to deviant sounds. This correlation reflects how neural activation affects neural differentiation for each individual participant

  • Sensory Profile 2Baseline/before baseline

    The Sensory Profile is a self report or parent report measure of responses to sensory stimuli. Total symptoms are categorized as "much less than others", "less than others", "same as others", "more than others", and "much more than others" for each participant.

  • Sensory Experiences Questionnaire (SEQ)Baseline/before baseline

    The Sensory Experiences Questionnaire is a self report or parent report measure of responses to sensory stimuli in the everyday environment

  • Sensory Perception QuotientBaseline/before baseline

    The Sensory Perception Quotient is a self-reported measure of sensory concerns and symptoms

  • Repetitive Behavior Questionnaire-2Baseline/before baseline

    Self or parent report measure of restrictive and repetitive behaviors

  • Adult Repetitive Behaviours Questionnaire-2Baseline/before baseline

    Self or parent report measure of restrictive and repetitive behaviors

  • Stanford-Binet Intelligence Scales, Fifth edition (SB-5)Baseline

    IQ is a standardized measure of both verbal and nonverbal abilities, which will be measured with the Stanford Binet V. Standard scores range from 40-160, with a mean of 100 and higher scores indicating increased cognitive ability.

  • hand dexterity ratio from the Purdue Pegboard taskBaseline

    The number of pegs placed for the left and right hands in a given amount of time in ratio form, reflects relative dexterity of the right and left hands

  • Edinburgh Handedness questionnaireBaseline/before baseline

    self or parent report measure of which hand (left or right) is used for everyday tasks and how consistently

  • Autism Spectrum QuotientBaseline/before baseline

    self or parent report of an individual's experience of autism symptoms in daily life

  • Social Responsiveness Scale, Second EditionBaseline/before baseline

    self or parent report of symptoms of autism seen in daily life. T scores have a mean of 50 and a range of 32-114, with higher scores indicating more autism symptoms.
