Abstract

Although the acquisition of a novel word is apparently rapid, adult research suggests that integration of novel and existing knowledge (measured by engagement in lexical competition) requires sleep‐associated consolidation. We present the first investigation of whether a similar time‐course dissociation characterizes word learning across development. Consistent with previous research but counter to adults, 7–12‐year‐olds showed sleep‐associated consolidation effects in declarative but not procedural memory. Nevertheless, the relationship between sleep and word learning in children was remarkably similar to the pattern for adults. Following exposure to nonword competitors (e.g. biscal) in the a.m. or p.m., children’s ability to recognize and recall the nonwords improved only after sleep (after approximately 12‐hrs for the p.m. group and 24‐hrs for the a.m. group), with performance stable 1 week later. Novel nonwords only induced lexical competition effects after sleep. These findings suggest that children utilize a dual memory system when acquiring and integrating new vocabulary and highlight sleep as integral to this process.

  • Several other studies demonstrated profits from sleep in children aged 7-14 for word memories and integration of novel words into lexical knowledge.

    “Similarly, several other studies demonstrated profits from sleep in children between 7 and 14 years of age for word memories as well as for the integration of novel words into lexical knowledge (141, 530, 945).”

    From About Sleep's Role in Memory (2013) · cites this paper as [530]

    The Abstract reports that 7–12-year-olds improved in recognition and recall of novel words after sleep, and that the words produced lexical competition only after sleep. This supports the word-memory and lexical-integration findings, but this paper does not establish them for the full stated 7–14 age range. (LLM, conf=0.84)

    Experimental — accuracy not yet measured

  • Sleep promotes integration of newly learned spoken words into existing knowledge networks in adults and children.

    “Thus, in adults and children, sleep promoted the integration of newly learned spoken words into existing knowledge networks as measured by a lexical competition task (333, 334, 530; but see Ref. 735), with this effect being associated with increased spindle activity (1175).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
