Dunn's Sensory Processing FoR - Brian's "picky eating" habits necessitate further investigation into the reasoning behind it and under this FoR, his sensory profile. He shows avoidance behaviors regarding certain textures, self-feeding, and cup use which all may be explained using Dunn's sensory processing framework. In typically developing children, tactile, auditory, and taste and smell sensory systems are most impactful on food selectivity (Esposito et al., 2019). The sensory processing framework explains that sensory hypersensitivity can make a wide variety of foods aversive which causes these avoidance behaviors (Esposito et al., 2019).
