Memory functioning and mental verbs acquisition in children with specific language impairment.
For kids with SLI, weak working and long-term memory blocks mental-verb learning, so check memory first.
01Research in Context
What this study did
Spanoudis et al. (2011) compared kids with specific language impairment to same-age peers. They tested working memory, long-term memory, and mental-verb words like "think" and "know."
Each child repeated number strings, recalled stories, and explained cartoon pictures. The team asked: do memory gaps explain why SLI kids struggle with mental verbs?
What they found
Children with SLI scored lower on every memory and mental-verb task. Memory scores, not language exposure, best told the groups apart.
The worse the working memory, the fewer mental verbs the child used. Long-term memory added extra power in predicting who had SLI.
How this fits with other research
Vugs et al. (2014) and Roello et al. (2015) extend these results downward to preschool. They show SLI three-year-olds already have weak working memory and executive function, so the memory gap starts early.
Marini et al. (2014) looks almost opposite at first: they found verbal working memory hurt grammar but not story-telling in SLI. The difference is task type. Andrea studied live talking; C et al. studied single mental verbs. Memory load matters most when the child must hold tricky words online.
Laposa et al. (2017) adds a twist: procedural memory linked to grammar speed in typical kids but not in SLI. Together the papers say different memory systems shape different language bricks in SLI, so we need to test more than one store.
Why it matters
Before you teach "think, know, guess," run a quick memory probe. If the child cannot hold three numbers, swap the goal for shorter sentences or visual aids. Target memory first or pair each mental verb with a picture cue to cut load. This small shift can save weeks of stalled language therapy.

03Original abstract
Memory and language operate in synergy. Recent literature stresses the importance of memory functioning in interpreting language deficits. Two groups of 50 children each, ages 8-12 were studied. The first group included children with specific language impairment, while the participants in the second group were typically developing children. The two groups, which were matched on age, nonverbal intelligence and varied significantly in verbal ability were examined, using a test battery of four memory functioning (phonological, working and long-term memory) and five mental verb measures. The statistical analyses indicated that the two groups differed significantly in all language and memory measures; a logistic regression analysis revealed that within each main group existed nested subgroups of different developmental patterns with working and long-term memory measures as the most robust discriminate markers of classification. Language impaired children had more difficulties in the acquisition of mental verbs because they are less able to process and store phonological information in working memory and long-term lexicon.
