Abstract
Separate evaluations of bite size (amount of food on the spoon) and food texture were used to prescribe treatment changes in a feeding protocol for a 3‐year‐old male with autism and severe food selectivity. Each evaluation revealed distinct behavioral topographies, with an increase in disruptive behaviors associated with increased bite sizes and decreased swallowing and higher rates of gagging associated with higher textures. The results of each evaluation were used to successfully guide increases in volume and texture during therapeutic meals. Results highlight the importance of considering both aversion to food as well as oral motor skills when designing treatment for children with food selectivity.
