Sensory Sensitivity or Behavioral Reaction? Investigating the Impact of Environmental Modifications on Emotional Regulation in Children with Sensory Processing Difficulties

Abstract: Children with sensory processing difficulties frequently exhibit behavioral outbursts, but it remains unclear whether these reactions stem from sensory overload or behavioral self-regulation deficits. Distinguishing between these causes is essential for effective occupational therapy interventions, as strategies for addressing sensory reactivity differ from those targeting emotional regulation difficulties. This study examined whether environmental modifications could reduce behavioral outbursts and physiological stress responses in children with sensory processing difficulties. A within-subjects experimental design was used, with 20 children (ages 5–10) exposed to two environmental conditions: an unregulated sensory environment (fluorescent lighting, unpredictable loud noises, overlapping sensory stimuli) and a controlled sensory environment (dim lighting, noise-reducing headphones, weighted blankets, and structured sensory input). Each session lasted 30 minutes, with behavioral responses systematically recorded through structured observation, heart rate variability (HRV) monitoring, and caregiver/therapist assessments. Paired t-tests revealed a significant reduction in behavioral outbursts in the controlled environment, while HRV data indicated lower physiological stress levels. Qualitative feedback from therapists and caregivers highlighted improved self-regulation and engagement in the sensory-modified setting. These findings suggest that many behavioral outbursts in children with sensory processing difficulties may be primarily sensory-driven rather than solely behavioral in nature. Occupational therapy interventions should prioritize sensory-informed strategies, emphasizing environmental modifications to enhance emotional regulation and functional participation in children with sensory challenges.
