Language, social, and executive functions in high functioning autism: a continuum of performance.

The team looked at high-functioning autistic kids. They tested grammar, figurative talk, planning, memory, and set-shifting.

They wanted to see if language, social, and executive skills move together or on their own.

Kids struggled with expressive grammar and figurative lines like "it’s raining cats and dogs."

Planning and spatial memory were weak, and set-shifting looked odd. Surprisingly, these skills did not predict social success.

Richman et al. (2001) saw the same figurative trouble four years earlier, so the weakness is stable.

Kritsotakis et al. (2026) later repeated the finding and added that poor morphosyntax drives the gap, not age.

Lampri et al. (2024) pooled many studies and agree: Theory of Mind and verbal skill matter most for figurative language; executive scores add little. This seems to clash with J et al.’s focus on executive deficits, but the two teams used different tasks. J et al. used cool lab puzzles; Stella counted everyday figurative errors. The puzzles tap different brain routes, so both can be true.

Memisevic et al. (2023) extend the story downward: in younger autistic kids only planning and working memory track autism severity, echoing the uneven profile seen here.

When you assess a bright autistic client, probe figurative language and grammar directly. Do not assume strong executive scores protect them, and do not wait for social problems to show up. Start explicit figurative-language drills and planning supports now, even if the child scores in the normal range on classic EF tests.
