Definition
Working memory is the ability to hold and manipulate information in mind over short periods, for example following multi-step instructions, mental arithmetic, or holding the start of a sentence while writing the end. The Baddeley-Hitch model (1974, revised 2000) is the standard framework, dividing working memory into phonological loop, visuospatial sketchpad, central executive, and episodic buffer.
In context for parents
Key checkpoints
- The ability to hold and manipulate information in mind over short periods.
- The Baddeley-Hitch model (1974, revised 2000) is the standard framework: phonological loop, visuospatial sketchpad, central executive, episodic buffer.
- Frequently affected in dyslexia (phonological), ADHD (central executive), autism, FASD.
- WISC-V Working Memory Index combines Digit Span and Picture Span; below the 5th centile indicates significant difficulty.
- Section F should specify working memory adjustments: named tools, named scaffolds, named training.
Working memory is one of the most frequently affected cognitive systems in SEND. Dyslexia commonly shows reduced phonological working memory. ADHD shows reduced central executive working memory. Autism profiles vary but often show relative weakness in verbal working memory alongside relative strength in visuospatial working memory. FASD frequently shows working memory at the 1st centile.
In a Year 4 classroom, working memory difficulty looks like the child who cannot follow "put your book away, line up at the door, and bring your reading folder". The first instruction is followed; the rest are lost. Or the child whose mental arithmetic stops at "37 plus 18" because by the time they have added 7 and 8 they have forgotten 30 and 10. Or the child whose written work shows beautiful first sentences and degrading subsequent ones, because each sentence consumes the working memory needed for the next.
The WISC-V Working Memory Index combines Digit Span and Picture Span. A child with a Working Memory Index at the 5th centile is showing significant difficulty, and that difficulty has implications across the curriculum: reading comprehension, mental maths, written composition, following multi-step instruction, organising long-term projects.
What helps:
- Reducing working memory load (instructions broken into single steps; written instructions alongside verbal; visual supports; one task at a time).
- External memory aids (writing it down; checklists; planners; visual timers).
- Pre-teaching (which reduces the working memory demand of a new concept).
- Repeated practice (which moves information from working memory to long-term memory).
- Voice typing for writing tasks (which reduces the working memory demand of handwriting and spelling).
What does not help:
- Asking the child to "try harder", "concentrate more", or "listen better".
- Verbal-only instructions in series.
- Open-ended tasks without scaffolding.
- Mental-arithmetic-by-default without paper.
In an EHCP, Section F should specify working memory adjustments (named tools, named scaffolds, named training) rather than generic "support".
Related terms
The terms parents most often see alongside Working Memory.
Executive Function
The brain's set of self-management skills: planning, starting and stopping tasks, organising, switching attention, and impulse control. Frequently affected in ADHD, autism, and dyspraxia.
ADHD
A neurodevelopmental condition affecting attention, impulse control, and activity levels. Often co-occurs with autism, dyslexia, or anxiety, and presents differently in girls and boys.
Dyslexia
A specific learning difficulty affecting accurate and fluent word reading and spelling. It is independent of intelligence and typically responds well to structured, multisensory phonics teaching.
Wechsler Intelligence Scale for Children(WISC)
A widely used standardised assessment of cognitive ability for children aged 6-16, producing index scores for verbal comprehension, visual-spatial, fluid reasoning, working memory, and processing speed.
Where parents ask about this
Parents usually find this page when a WISC-V report has shown a Working Memory Index well below the rest of the profile, or when a school is treating working-memory difficulty as inattention. Searches include "working memory ADHD child", "low working memory school strategies", and "WISC Working Memory Index". A Beaakon EP can carry out a WISC-V plus deeper working memory assessment (AWMA: Automated Working Memory Assessment), interpret the profile, and write Section F provision matched to it.
