This study examined whether sensory modulation disorder–sensory overresponsivity (SMD–SOR) and attention deficit hyperactivity disorder (ADHD) have a significant effect on the perception of aversive auditory stimuli. Participants were 66 young adult women. The diagnosis of SOR was made using the Sensory Responsiveness Questionnaire, and ADHD was diagnosed by a qualified psychiatrist or neurologist using criteria from the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.). Participants were presented with the Battery of Aversiveness to Sounds, short presentations of daily life sounds, and rated each sound stimulus verbally according to its perceived unpleasantness. Participants with SOR rated low-intensity aversive sounds as significantly more aversive than participants without SOR. High-intensity sounds obtained a marginal significant difference exclusively in participants with ADHD. The perception of aversive auditory stimuli in adults with SOR appears to be unique and different than the profile of adults with ADHD.
