Who they are
Grace T. Baranek is an American occupational therapist and researcher who has been one of the most productive investigators in sensory processing and autism over the past three decades. She is a professor at the University of Southern California’s Chan Division of Occupational Science and Occupational Therapy, and the developer of the Sensory Experiences Questionnaire (SEQ) — one of the few sensory assessment instruments designed specifically for autistic populations. See Sensory Experiences Questionnaire.
Baranek’s work focuses on early identification through sensory processing patterns, which appear in infancy before the social-communication differences that typically trigger diagnosis.
Key contributions
The Sensory Experiences Questionnaire (SEQ)
Baranek developed the SEQ in multiple versions (v1, v2.1, research-grade v3.0 with 105 items). It distinguishes four response patterns and uniquely separates social from nonsocial contexts—a child responds differently to a car horn than a human voice, even though both are auditory.
Early sensory markers
Baranek’s longitudinal research shows sensory features, particularly hyporesponsiveness, are identifiable in the first year of life in infants later diagnosed autistic. This connects sensory processing to developmental trajectories and early intervention.
Sensory subtyping
Baranek’s work shows autistic people fall into sensory subtypes, not a single profile. There is no single autistic sensory experience, and interventions must match individual patterns.
Critical assessment
The SEQ remains primarily a research instrument — it is not commercially available for clinical use, which limits its practical impact relative to the Dunn Sensory Profiles. The instrument focuses on ages 2–12, leaving adolescents and adults unserved. No Dutch validation exists.
Baranek’s early-identification work, while promising, raises questions about the ethics and consequences of very early sensory screening. Identifying sensory differences in infancy could lead to early support — or to early pathologising of natural variation, depending on how the information is used.
