Purpose Incidental reading provides a powerful opportunity for partial word knowledge growth in the school-age years. The extent to which children of differing language abilities can use reading experiences to glean partial knowledge of words is not well understood. The purpose of this study was to compare semantic–syntactic partial word knowledge growth of children with higher language skills (HL group; overall language standard scores of 85 or higher) to that of children with relatively lower language skills (LL group; overall receptive or expressive standard score below 85). Method Thirty-two children, 16 per group, silently read stories containing unfamiliar nouns and verbs 3 times over a 1-week period. Semantic–syntactic partial word knowledge growth was assessed after each reading and 2–3 days later to assess retention. Results Over time, both groups showed significant partial word knowledge growth, with the HL group showing significantly more growth. In addition, both groups retained knowledge several days later. Conclusion Regardless of language skill level, children benefit from multiple exposures to unfamiliar words in reading in their development and retention of semantic–syntactic partial word knowledge growth.

Most vocabulary growth during the school-age years occurs incidentally. However, little is understood about the influence of language skills on word knowledge growth during reading. Using a pretest–posttest quasi-experimental design, we examined incidental word learning through reading, considering the presence/absence of supportive context and the role of language ability. Children with a range of language abilities ( N = 32), aged 10 years, 6 months to 16 years, 5 months, were exposed three times to rare nouns and verbs within stories or in isolation. Small but significant knowledge gains were found for rare words encountered in context, but not for words in isolation. Language skill predicted overall word knowledge but not rate of word knowledge growth. Findings suggest children with low oral language ability are at a disadvantage in acquiring vocabulary through reading; however, the word learning process may be qualitatively similar for children with varying language skill levels.

Purpose: Although school-age children learn most new word meanings from surrounding context, the joint roles of language ability and executive function (EF) in the word learning process remain unclear. This study examined children's acquisition of word meanings from context in relation to oral language ability and three EF skills (working memory, inhibitory control, and cognitive flexibility). Method: Typically developing school-age children completed measures of language and EF, then read and listened to short stories containing unfamiliar target words. A multiple-choice pretest–posttest measure assessed children's target word knowledge gains. Results: Regression analyses showed that language and cognitive flexibility were both related to word knowledge gains; each skill assumed greater importance among children with relative weakness in the other skill. Conclusion: Language ability and cognitive flexibility may each play a direct role in contextual word learning among school-age children, with children naturally relying on one skill if the other is weaker.

Caregivers' perceptions regarding their child's language disorder may influence caregivers' involvement in therapy as well as daily home interactions, thus impacting developmental outcomes. However, little is known about the alignment between caregivers' perceptions of their child's language disorder and those of speech-language pathologists (SLPs), nor of factors that might relate to alignment between caregivers and SLPs. This study addressed three aims: (1) to characterize caregivers' perceptions regarding children's of communicative interactions, in communicative abilities, and of communicative improvement; (2) to measure alignment between caregivers' and SLPs' perceptions; and (3) to explore caregiver- and child-level factors that might relate to alignment. Caregivers and SLPs of 3- to 4-year-old children currently receiving treatment for language disorders completed questionnaires to assess perceptions along with two caregiver factors (maternal education and self-efficacy) and child language disorder severity. Caregivers' perceptions were more positive and more variable than those of SLPs. However, caregivers and SLPs agreed in rating perceptions of present and future higher than either or. Maternal education, caregiver's self-efficacy, and children's language disorder severity were not related to alignment between caregivers and SLPs. Given the variability in caregivers' perceptions, future research should explore the role of perceptions in children's language intervention outcomes.
