The Triple I Hypothesis: taking another('s) perspective on executive dysfunction in autism.

McDowell (2013) wrote a theory paper about autism and executive function. The author asked: what if poor scores on EF tasks come from not knowing the hidden rules?

The paper says many autistic people fail EF tests because they do not see the examiner’s point of view. The name "Triple I" stands for "Inability to take another’s perspective causes Illusion of executive dysfunction."

The paper argues there is no single executive deficit in autism. Instead, missed social cues make the person look like they cannot plan or shift.

When the task is made clear and perspective is taught, the same person often passes the EF test.

Ko et al. (2024) seems to disagree. They report that EF scores explain most autism symptoms in preschoolers. The clash is about age and method. The 2024 study used standard EF tests and parent ratings, while McDowell (2013) looks at moment-to-moment task understanding.

Cantio et al. (2016) and Yu et al. (2021) back the Triple I view. They show that theory-of-mind skill, not raw EF, drives group differences and mediates hot-cool EF links.

Laugeson et al. (2014) extends the idea to the whole autism triad, saying each symptom cluster may have its own cognitive path rather than one shared EF problem.

Before you write "executive dysfunction" in a report, probe the client’s grasp of the unspoken rules. Model the examiner’s perspective, rephrase instructions, or let the child state the goal in their own words. A quick perspective-check can turn a failed trial into a pass and keep your treatment plan focused on social cognition instead of generic EF drills.
