# Working Memory and the ICF Domain (b1440)

In the ICF, Working Memory maps to b1440 (short-term memory), within memory functions (b144) under Mental functions (b1) in the Body Functions component. It describes the capacity to briefly hold and use information online — for example recalling a two-step instruction. The ICF captures functioning, not diagnosis, linking this capacity to everyday activities and participation in early childhood.

*Working memory is the mental workspace where a young child briefly holds and manipulates information — and in the ICF it maps cleanly to a specific functioning code.*

## In short
In the **International Classification of Functioning, Disability and Health (ICF)**, Working Memory maps to **b1440 — short-term memory**, nested within the chapter of **Mental functions (b1)** and more specifically the **memory functions (b144)** group. It belongs to the *Body Functions* component of the ICF, under the broader domain of cognitive (mental) functions. In early childhood this is the capacity to hold a small amount of information "online" for a few seconds and use it to guide an immediate action — recalling a two-step instruction, holding the start of a sentence while finishing it, or keeping a rule in mind during play.

## The science: where it sits in the ICF architecture
The ICF is organised hierarchically. At the top sits the component *Body Functions (b)*; within it, *Mental functions (b1)*; within that, *Specific mental functions (b140–b189)*, which house *Memory functions (b144)*. The code **b1440** denotes **short-term memory** — "a memory store of limited capacity and duration from which information is lost if not consolidated." Contemporary cognitive science frames working memory as more than passive short-term storage — it includes active manipulation and attentional control — yet within the ICF taxonomy it is operationalised under b1440, often considered alongside b1400 (sustaining attention) and b1641 (organising and planning) when a clinician profiles a child's executive functioning. Importantly, the ICF describes *functioning*, not diagnosis: it captures how well a capacity operates and how it interacts with activities, participation and environment, which makes it well suited to the strengths-based, whole-child profiling used in early-childhood developmental work.

## Why this mapping matters in early childhood
For researchers and clinicians, mapping working memory to b1440 allows a child's cognitive profile to be described in a shared, interoperable language that links body-function capacities to real-world activities (ICF *Activities and Participation*, d-codes) such as carrying out daily routines or learning to read. This supports cross-study comparability and goal-setting that connects an underlying capacity to the everyday participation it enables.

## The Pinnacle way
This is general educational information, not a diagnosis — a clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care, through a structured clinician-administered assessment, never from an app or form. Our teams profile working memory alongside attention, language and executive skills, then translate findings into an individualised plan that may draw on [occupational therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate) and other supports. Learn more about how we measure and support development at [Pinnacle Blooms Network](/).

**Next step —** If you are mapping a child's cognitive profile or wish to understand working-memory functioning in context, arrange a developmental review to translate ICF-aligned capacities into practical, goal-led support.
