Verbal working memory in children with mild intellectual disabilities.
Kids with mild ID have weaker phonological working memory and executive control than same-age peers—target these areas in academic support.
01Research in Context
What this study did
Stancliffe et al. (2007) compared working memory in teens with mild intellectual disability to same-age peers without disabilities.
They used short tests that tap the phonological loop and the central executive.
The design was quasi-experimental: kids were matched by age, not randomly chosen.
What they found
The ID group scored lower on both phonological and executive tasks.
The gap looked like a delay, not a different pattern.
How this fits with other research
Xenitidis et al. (2010) later saw the same weak scores but argued the phonological problem is a hard-wired abnormality, not just slow growth.
Cudré-Mauroux (2010) shifted focus to the episodic buffer and found kids with ID kept pace with mental-age peers on story recall, showing some memory systems do follow developmental time.
Ilan et al. (2021) gave adults with mild ID a voice: saying words aloud during study lifted later recall, proving the phonological gap can be worked around.
Why it matters
You now know that phonological and executive working memory are soft spots for students with mild ID.
Use short verbal lists, allow vocal rehearsal, and teach note-taking tricks that cut memory load.
These tweaks turn the assessment finding into a practical support plan.

03Original abstract
BACKGROUND: Previous research into working memory of individuals with intellectual disabilities (ID) has established clear deficits. The current study examined working memory in children with mild ID (IQ 55-85) within the framework of the Baddeley model, fractionating working memory into a central executive and two slave systems, the phonological loop and visuo-spatial sketchpad. METHOD: Working memory was investigated in three groups: 50 children with mild ID (mean age 15 years 3 months), 25 chronological age-matched control children (mean age 15 years 3 months) and 25 mental age-matched control children (mean age 10 years 10 months). The groups were given multiple assessments of the phonological-loop and central-executive components. RESULTS: The results showed that the children with mild ID had an intact automatic rehearsal, but performed poorly on phonological-loop capacity and central-executive tests when compared with children matched for chronological age, while there were only minimal differences relative to the performance of the children matched for mental age. CONCLUSIONS: This overall pattern of results is consistent with a developmental delay account of mild ID. The finding of a phonological-loop capacity deficit has important implications for the remedial training of children with mild ID.
