Influence of Semantic Richness on Word Form Learning in Children With Developmental Language Disorder.

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
purposeChildren with developmental language disorder (DLD) show a word form learning deficit, characterized by inaccurate and variable productions of novel words. We investigated whether, when a novel word form is introduced, incremental exposure to either a sparse visual referent or a relatively semantically rich story influences the phonetic accuracy and the phonological and articulatory variability of production in children with DLD and their typically developing (TD) peers.
methodThirty-six preschoolers (18 DLD, 18 TD) aged 4;1-5;11 (years;months) were exposed to six novel words, two in each of three semantic cue conditions: no cues, sparse cues (visual referent), and rich cues (story). Children participated in three learning sessions. The first session consisted of nonword practice of word forms, and the present study only included the later consolidation sessions (Sessions 2 and 3) during which semantic content was incrementally incorporated. Phonetic accuracy, phonological variability, articulatory variability, referent identification, and confrontation naming measures were used to evaluate learning.
resultsThe most robust result was that children with DLD were less phonetically accurate and more phonologically variable than their TD peers, although variability decreased across sessions. For only children with DLD, phonetic accuracy decreased in the rich story condition. However, both TD and DLD groups showed increased variability in the rich story condition. In the slower mapping sessions included in this study, children with DLD and TD children showed similar performance in speech motor (i.e., lower lip/jaw motion) variability as well as in comprehension and confrontation naming of semantic referents.
conclusionsChildren with DLD demonstrate deficits in their capacity to organize phonological sequences. Phonological organization shows some malleability based on the type of semantic information presented during learning, with relatively rich and elaborated input (as opposed to simple naming) disrupting the organization of phonological sequences.
