The relationship between executive functioning, central coherence, and repetitive behaviors in the high-functioning autism spectrum.

Mikle et al. (2007) tested two popular ideas about high-functioning autism. One idea says poor executive function drives repetitive behaviors. The other says weak central coherence does the same. The team gave teens and young adults with autism two kinds of tasks. They used the Wisconsin Card Sorting Task for executive function. They used embedded-figures tests for central coherence. Then they checked if either skill lined up with how many repetitive behaviors each person showed.

The Wisconsin scores did link to repetitive behaviors. Kids who sorted cards poorly also showed more hand-flapping or lining up toys. The embedded-figures scores did not link at all. Good or bad detail-spotting had zero bearing on repetitive actions. So only part of the old theory held water.

Lincoln et al. (1988) mapped the IQ profile in the same group years earlier. They found verbal IQ beats visual-motor IQ. Mikle adds that executive slips, not visual style, feed into rituals. Pathak et al. (2019) later showed that higher-IQ kids with autism still lag in daily living skills. The gap fits Mikle’s point: thinking flexibility matters more than detail focus for real-life adaptation. Gotham et al. (2015) also tried to validate questionnaires in verbal autistic teens. Like Mikle, they found standard tools only partly work. Together these papers warn us: simple coherence tasks don’t explain autism behaviors, and we need sharper measures.

When you see a bright teen who lines toys or repeats phrases, don’t blame weak central coherence. Instead, test set-shifting and flexibility. Add sorting or Stroop tasks to your assessment. Target executive skills in intervention. Teach the child to stop, plan, and choose a new action. That route has data behind it; detail-spotting drills do not.
