Temperament and sensory features of children with autism.
Sensory under-responsiveness in autism comes with a predictable calm-but-stuck temperament package.
01Research in Context
What this study did
Meier et al. (2012) asked parents to fill out two checklists. One rated the child’s temperament. The other rated sensory habits.
The sample included children with autism, children with developmental delay, and typically developing peers.
Researchers then looked for links between sensory scores and nine temperament traits.
What they found
Kids with autism scored differently on eight of the nine temperament scales.
The standout link: children who were slow to notice sights, sounds, or touch also showed low adaptability, low reactivity, and low distractibility.
In plain words, the "tuned-out" sensory pattern matched a calm, hard-to-move temperament.
How this fits with other research
Ben-Sasson et al. (2009) already showed that under-responsivity is the biggest sensory red flag for autism. E et al. add the temperamental profile that travels with it.
Schaaf et al. (2015) later tracked heart-rate variability during sensory tasks and found the same under-responsive kids had sluggish parasympathetic responses. The biology backs the behavior.
McQuaid et al. (2024) seem to disagree at first glance—they report that kids with sensory over-responsivity have social brain differences. The key difference is direction: E et al. studied under-responsivity; A et al. studied over-responsivity. Together they map both ends of the sensory spectrum.
Kirby et al. (2016) watched families at home and saw hyper-responsive behaviors spike during adult-led routines. E et al.’s findings remind us to also watch for the quiet, slow-to-adapt child during those same routines.
Why it matters
If a child barely reacts to noise or touch, expect trouble shifting activities and low emotional swings. Use visual schedules, give extra warning before transitions, and pair new tasks with highly preferred items to boost reactivity. The same profile that looks "easy" may actually be "stuck," so plan your prompts accordingly.

03Original abstract
This study sought to characterize temperament traits in a sample of children with autism spectrum disorder (ASD), ages 3-7 years old, and to determine the potential association between temperament and sensory features in ASD. Individual differences in sensory processing may form the basis for aspects of temperament and personality, and aberrations in sensory processing may inform why some temperamental traits are characteristic of specific clinical populations. Nine dimensions of temperament from the Behavioral Style Questionnaire (McDevitt and Carey in Manual for the behavioral style questionnaire, Behavioral-Developmental Initiatives, Scottsdale, AZ, 1996) were compared among groups of children with ASD (n = 54), developmentally delayed (DD; n = 33), and the original normative sample of typically developing children (McDevitt and Carey in J Child Psychol Psychiatr 19(3):245-253, 1978; n = 350) using an ANOVA to determine the extent to which groups differed in their temperament profiles. The hypothesized overlap between three sensory constructs (hyperresponsiveness, hyporesponsiveness, and seeking) and the nine dimensions of temperament was analyzed in children with ASD using regression analyses. The ASD group displayed temperament scores distinct from norms for typically developing children on most dimensions of temperament (activity, rhythmicity, adaptability, approach, distractibility, intensity, persistence, and threshold) but differed from the DD group on only two dimensions (approach and distractibility). Analyses of associations between sensory constructs and temperament dimensions found that sensory hyporesponsiveness was associated with slowness to adapt, low reactivity, and low distractibility; a combination of increased sensory features (across all three patterns) was associated with increased withdrawal and more negative mood. Although most dimensions of temperament distinguished children with ASD as a group, not all dimensions appear equally associated with sensory response patterns. Shared mechanisms underlying sensory responsiveness, temperament, and social withdrawal may be fruitful to explore in future studies.
