Phonological memory and word learning deficits in children with specific language impairment: A role for perceptual context?
Preschoolers with SLI fail to ‘lock in’ new words through repetition, so pair each word with a visual or motor cue and plan next-day refreshers.
01Research in Context
What this study did
Moav-Scheff et al. (2015) watched preschoolers with Specific Language Impairment learn new words.
They gave the kids short made-up names for toys and repeated each name several times.
The team then tested how well the children held the new words in memory after the repetition.
What they found
The SLI group did worse at both remembering and saying the new words.
Kids with typical language got a boost each time a word was repeated, but the SLI group did not.
The authors call this missing boost ‘reduced anchoring’—the repetition did not stick.
How this fits with other research
Desmottes et al. (2016) saw the same quick loss in SLI, but with motor sequences instead of words. Their kids learned finger patterns fine at first, then forgot them the next day.
Bryłka et al. (2024) found a mirror image: children with DLD had weak memory only when pictures could be named. Together the three studies show the problem is not sound alone—it is any task that invites silent talking.
Fancourt et al. (2026) looked at musical memory and got a bright spot: DLD kids kept melodies better when they could use visual cues. This suggests giving pictures, gestures, or colors may give the anchoring that bare repetition does not.
Why it matters
When you teach a new word or sign, do not rely on simple drill. Pair the item with a gesture, color, or picture and space quick reviews across the day. If the child still loses the word overnight, plan booster sessions the next morning—the weakness is holding on, not first picking up.

03Original abstract
BACKGROUND: Sensitivity to perceptual context (anchoring) has been suggested to contribute to the development of both oral- and written-language skills, but studies of this idea in children have been rare. AIMS: To determine whether deficient anchoring contributes to the phonological memory and word learning deficits of children with specific language impairment (SLI). METHODS AND PROCEDURES: 84 preschool children with and without SLI participated in the study. Anchoring to repeated items was evaluated in two tasks - a phonological memory task and a pseudo-word learning task. OUTCOMES AND RESULTS: Compared to children with typical development, children with SLI had poorer phonological memory spans and learned fewer words during the word learning task. In both tasks the poorer performance of children with SLI reflected a smaller effect of anchoring that was manifested in a smaller effect of item repetition on performance. Furthermore, across the entire sample anchoring was significantly correlated with performance in vocabulary and grammar tasks. CONCLUSIONS AND IMPLICATIONS: These findings are consistent with the hypothesis that anchoring contributes to language skills and that children with SLI have impaired anchoring, although further studies are required to determine the role of anchoring in language development.
