![]() The habituation description of people with ASD (Robertson et al. Habituation is an automatic form of learning in which the body learns not to physiologically respond to stimuli that are familiar, predictable or not relevant anymore (McDiarmid et al. In other words, when a stimulus is repeated multiple times the physiological response to the stimulus slowly decreases or will get extinct. ![]() Habituation refers to response distinction after a stimulus has repeatedly been presented (Houtveen et al. This description is similar to what experimental studies on learning call “habituation”. ![]() Moreover, some ASD adults expressed that they were not able to get used to certain sensory stimuli as other people without ASD seemed to do (Robertson et al. For instance, certain frequencies can be extremely annoying (e.g., computer fan), loud noises can be painful (e.g., fog horn) and combined sounds such as multiple people talking to each other at once can be overwhelming (e.g., for review see Elwin et al. Studies, clinical observations, and autobiographies show that people with ASD perceive certain sounds as more intense. 2006 Kientz and Dunn 1997 Tomchek and Dunn 2007). One of the most commonly reported sensory sensitivities in ASD is sensitivity to sounds (Baranek et al. In the current paper, we will focus on two possible underlying factors that might play a role in auditory sensitivity in ASD adults, namely habituation and detection thresholds. These findings make it even more crucial to examine possible underlying mechanisms of sensory sensitivity in ASD, as this might provide us with information we need to develop successful treatments for sensory sensitivities that are perceived as problematic by those with ASD. For instance, sensory sensitivity has been related to social difficulties and the presence of more repetitive behavior (e.g., Deschrijver et al. Besides this relatively high prevalence, sensory sensitivities are recently described to be related to other characteristics of ASD. Even though someone can meet the criteria for an ASD classification without meeting the sensory sensitivity criterion, the reported prevalence of sensory sensitivities in people with ASD is high (60 to 96% for review see Schauder and Benneto 2016). Nowadays, sensory sensitivities are included as a criterion for the classification of ASD in the Diagnostic and Statistical Manual of Mental Disorders 5 (DSM-). Sensory sensitivities were already reported in the first descriptions of autism by Leo Kanner (Kanner 1943). It is well known that many people with an autism spectrum disorder (ASD) diagnosis experience sensory sensitivities.
