Comprehension of Agentive and Psychological Verb Passives in Autistic Children With and Without Language Impairment: Evidence for Distinct Developmental Trajectories.
Article in Journal of autism and developmental disorders, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeWhile distinct pragmatic profiles are well-documented, grammatical abilities in autistic children show considerable heterogeneity: some exhibit grammatical difficulties, while others demonstrate age-appropriate grammar. Yet, one construction remains underinvestigated: passives of psychological/mental state verbs ("remember", "love"). This is critical because young children are known to comprehend passives of agentive verbs ("kiss", "push") via an adjectival passive strategy before acquiring passive grammar. This strategy fails for psychological verbs, making them the true test of passive knowledge. Despite extensive research in typically developing (TD) populations and populations with other neurodevelopmental conditions, there is little research examining both types of verbal passive in English-speaking autistic children.
methodsWe examined comprehension of agentive and psychological passives, short and long, in 48 autistic children divided into those with co-occurring language impairment (ALI, n = 26, mean age: 11;10), and those without (ALN, n = 22, mean age = 11;02), compared to two control groups matched on non-verbal reasoning (TD-Match-ALI, n = 22, mean age: 5;11 and TD-Match-ALN, n = 22, mean age: 10;03), on a sentence-matching task.
resultsChildren with ALN demonstrated age-appropriate performance across all constructions. In contrast, children with ALI performed at or below chance on both agentive and psychological passives, indicating absence of the adjectival strategy, and a profile distinct from all other groups including younger TD children.
conclusionsThe findings reveal distinct developmental trajectories: children with ALN show age-appropriate grammatical development, while children with ALI demonstrate fundamental syntactic impairments. These results highlight the importance of testing psychological verb passives to accurately identify grammatical difficulties that standardised assessments may miss.
