The Executive Function Account of Repetitive Behavior: Evidence From Rubinstein-Taybi Syndrome.

Waite et al. (2023) tested 30 people with Rubinstein-Taybi syndrome. They gave short thinking games that check inhibition, working memory, and set-shifting.

The team then watched which repetitive behaviors each person showed. They wanted to see if poor scores on a thinking game matched a certain behavior.

Repetitive questions went with poor inhibition and weak working memory. Hand flaps and body rocking linked only to poor inhibition. Strict routines went with trouble shifting from one task to another.

Each behavior had its own thinking signature. The results back the idea that executive glitches drive repetitive acts in RTS.

Chou et al. (2010) first saw that people with ID who were impulsive also showed more stereotypy. Jane’s work sharpens that picture by naming inhibition as the key link in RTS.

Wong et al. (2009) used caregiver talk instead of tests. They found anxiety behind repetitive questions in PWS and Fragile-X. Jane shows a thinking, not mood, root for the same topography in RTS. Same surface act, different insides.

Honey et al. (2008) watched toddlers with autism for 13 months. Repetitive scores rose, yet daily bother fell. Jane gives teens and adults with RTS a snapshot map. Together the papers span early childhood to adult life.

If a client with RTS keeps asking the same question, do not just block it. Train inhibition or working memory with turn-taking games or recall tasks. For body rocking, pick stop-and-go activities like Red Light-Green Light. For rigidity, use quick set-shifting drills such as switching sorting rules. Match the thinking skill to the behavior and you may cut the repetition at its root.
