1 · What the graph read from it

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.

2 · The registry

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

The ability to represent both local and nonlocal syntactic dependencies emerges in an infant's second year of life, raising questions about how these early syntactic representations interact with language learning in other domains. Using wh-questions as our case study, we investigate how infants' syntactic dependency acquisition interacts with their early lexical development. Prior work finds that 18-month-olds represent fronted wh-phrases as nonlocal arguments in object wh-questions with known verbs. Here, we show that 19-21-month-olds (range: 18;29-21;26) do the same when interpreting unknown verbs. We introduce a novel Violation of Fit method, a cross-modal extension of the Violation of Expectations paradigm. Infants saw dialogues with novel verbs in object wh-questions (e.g., What is the girl gonna gorp?), transitive polar questions (Is the girl gonna gorp the toy?), or intransitive polar questions (Is the girl gonna gorp?). At test, infants viewed a causal event (e.g., a girl knocks over a tower), and we measured their attention as an indication of whether they considered the verbs to be a good fit for this type of event. Across the age range, we found that infants who heard wh-question dialogues attended similarly to the test events as infants who heard canonical transitive dialogues, and unlike infants who heard intransitive dialogues. Thus, 19-21-month-olds treat object wh-questions with a novel verb as transitive when relating them to scenes. This suggests that immediately after wh-dependency representations are first acquired, they are available to feed verb learning. SUMMARY: We find that 19-21-month-olds represent wh-phrases (e.g., what) as nonlocal objects in wh-questions with unknown verbs (e.g., What is the girl gonna gorp?). We introduce a novel experimental paradigm, Violation of Fit, which measures how well an infant considers a particular sentence to fit with a particular scene. This test reveals that infants treat object wh-questions with a novel verb as transitive, and therefore a good fit to a causal event. This suggests that immediately after wh-dependency representations are first acquired, they are available to feed verb learning.
