This document describes a behaviour program to increase sharing behaviour in a 6-year-old boy named Jake during social interactions and playtime. Baseline data showed Jake shared an average of 11.11% of the time. The program used differential reinforcement of an alternative behaviour by providing reinforcement on a fixed interval schedule when Jake shared. Prompts were also used. After 20 days, Jake's sharing increased to an average of 37.22%. The program aims to continue maintaining this behaviour and generalize it to other settings by fading prompts and reinforcement over time.
