The Unlocking: An Autism Story unfolds in pandemic-stricken Melbourne, charting one family’s desperate battle against the escalating behavior of their autistic toddler. Amid the lack of in-person services, Harry exhibits severely restricted eating, obsessive-compulsive tendencies, crippling separation anxiety, and a demand avoidance that impedes every function in his young life. Harry meets the description of Pathological Demand Avoidance, a sub-type of autism that is not yet recognised in Australia, where an individual exhibits an anxiety-based need for control by avoiding the ordinary demands of living. During a break between lockdowns, and with much trepidation, the family embark upon a journey with applied behaviour analysis (ABA) therapy. ABA is an intensive therapy considered the gold standard in early intervention for autism, but with a controversial past. The outcome is life-changing. Beneath the veil of dysfunction and anxiety, they discover an outrageously creative, highly intelligent, and hilarious little boy.

In this episode Gregory Dobbs chats to Porscia Lam about the attitude adjustment she was compelled to make, the challenges she faced in understanding Pathological Demand Avoidance and Applied Behavioural Analysis therapy, and the impact on her family's mental health.
