Classification of children with autism spectrum disorder by sensory subtype: a case for sensory-based phenotypes.
Children with autism split into four sensory-based phenotypes, giving BCBAs a practical map for tailoring environmental supports.
01Research in Context
What this study did
Van Hanegem et al. (2014) asked parents to fill out the Sensory Profile for their children with autism. They ran a cluster analysis on the answers. The goal was to see if clear sensory 'types' show up inside the autism spectrum.
What they found
Four stable groups appeared. The team called them: sensory adaptive, taste-smell sensitive, postural inattentive, and generalized sensory difference. Age, IQ, and autism severity did not explain the groups. The clusters were driven only by how the children processed sights, sounds, touch, and movement.
How this fits with other research
Bizzell et al. (2020) extends this idea. They show one cut-off score on the same Sensory Profile can flag autism in boys with Down syndrome or XYY. You can use the tool for diagnosis, not just sub-typing.
Némorin et al. (2025) is a direct successor. Eleven years later the team repeated the cluster method but added adaptive skills and behavior data. They again found four subtypes at the time of diagnosis. The result confirms that clustering uncovers real clinical patterns beyond DSM-5 labels.
Masi et al. (2022) puts the subtypes to work. Kids in the generalized sensory difference cluster likely face more sleep problems. Screening sensory style can guide bedtime interventions.
Why it matters
You no longer have to treat 'sensory issues' as one big blur. Place each child in one of four sensory buckets. Match your intervention to the bucket. For example, a postural inattentive child may need a chair band or wiggle seat before table work. A taste-smell sensitive eater may accept new foods when you first let him sniff from a distance. Quick sensory typing gives you an individualized starting point on Monday morning.

03Original abstract
This study examines whether sensory differences can be used to classify meaningful subgroups of children with autism spectrum disorder (ASD). Caregivers of children with ASD aged 2-10 years (n = 228) completed the Short Sensory Profile. Model-based cluster analysis was used to extract sensory subtypes. The relationship of these subtypes to age, gender, autism symptom severity, and nonverbal intelligence quotient (IQ) was further explored. Four distinct sensory subtypes were identified: (a) sensory adaptive; (b) taste smell sensitive; (c) postural inattentive; and (d) generalized sensory difference. The sensory subtypes differ from each other on two dimensions: (a) the severity of reported sensory differences; and (b) the focus of differences across auditory, taste, smell, vestibular and proprioceptive domains. Examination of the clinical features of each subtype reveals two possible mechanisms of sensory disturbance in autism: (a) sensory hyperreactivity; and (b) difficulties with multisensory processing. Further, the sensory subtypes are not well explained by other variables such as age, gender, IQ, and autism symptom severity. We conclude that classification of children using sensory differences offers a promising method by which to identify phenotypes in ASD. Sensory-based phenotypes may be useful in identifying behavioral features responsive to specific interventions thereby improving intervention effectiveness. Further validation of the sensory-based phenotypes by establishing neural and physiological correlates is recommended.
