    Summary
    This summary is machine-generated.

    This study demonstrates a novel audiometric technique using negative reinforcement to assess hearing in individuals with profound intellectual disabilities. This method effectively identified a hearing disability in a non-responsive patient.

    Area of Science:

    • Behavioral Psychology
    • Audiology
    • Intellectual Disability Research

    Background:

    • Assessing sensory impairments in individuals with profound intellectual disabilities presents unique challenges.
    • Traditional assessment methods may be ineffective due to difficulties in finding suitable reinforcers or issues of satiation.

    Observation:

    • A 28-year-old female with profound intellectual disability was trained to avoid a mild foot shock using a visual cue.
    • The patient failed to consistently avoid the shock when an auditory cue was introduced, suggesting a hearing impairment.

    Findings:

    • The negative reinforcement audiometric technique successfully identified a hearing disability in a profoundly intellectually disabled patient.
    • This method overcomes limitations of positive reinforcement, such as finding effective reinforcers and avoiding satiation.

    Implications:

    • This technique offers a viable method for audiological assessment in non-responsive populations.
    • While ethical considerations regarding aversive stimuli exist, their use is increasingly accepted for individuals unresponsive to positive methods, under professional supervision.
