It is supported by Body Functions codes for intellectual (b117), attention (b140) and memory (b144) functions, reflecting the ICF practice of describing a developmental construct both as an underlying capacity and as a real-world learning activity. Permanence is best coded as a cognitive learning activity qualified by relevant mental-function codes rather than as a single discrete ICF item.","answer_md":"*Object permanence — knowing a hidden thing still exists — is a foundational cognitive milestone, and in the ICF it maps cleanly to a specific functioning domain.*\n\n## In short\nIn the **International Classification of Functioning, Disability and Health (ICF)**, the emerging capacity for **permanence** (object and person permanence) in early childhood maps to the **Activities and Participation** component, **Chapter d1 — Learning and applying knowledge**, and more specifically to the **basic learning** codes covering acquiring knowledge through manipulating objects and learning to act in relation to the persistence of objects (around **d110–d137**). It also draws on **Body Functions** under **b117 (intellectual functions)** and **b140 (attention functions)**, since permanence rests on early memory and attentional substrate. Permanence is therefore best understood as a cognitive functioning construct expressed through learning activities, not a single discrete code.\n\n## The ICF mapping in detail\nObject permanence — the understanding that objects and people continue to exist when out of sight — is a Piagetian sensorimotor achievement typically consolidating across roughly 8–12 months. The ICF, and its child-and-youth derivative concepts (ICF-CY, now integrated into the main classification), do not contain a literal code labelled \"permanence\". Instead, the construct is operationalised across two complementary components:\n\n- **Activities and Participation (d) — d1 Learning and applying knowledge.** Early permanence behaviours (searching for a hidden toy, anticipating a reappearing caregiver) are observable *learning activities*. They sit within purposeful sensory experience (**d110–d129**) and basic learning through objects (**d130–d137**), where the child learns that the world is stable and predictable.\n- **Body Functions (b) — global and specific mental functions.** The underlying capacities are captured by **b117 intellectual functions**, **b140 attention functions**, and the developing **b144 memory functions** that allow a representation to be held when a stimulus is no longer present.\n\nThis dual mapping reflects an important ICF principle: a developmental construct is described both as a *capacity/function* (Body Functions) and as a *performance in real environments* (Activities and Participation). For research coding in early childhood, permanence is most defensibly entered as a **d1 learning-and-applying-knowledge** activity, qualified by relevant **b1 mental function** codes.\n\n## Why this matters for measurement\nFraming permanence within ICF rather than a single test score lets clinicians and researchers describe both the child's intrinsic capacity and how environment and support shape its expression — keeping the focus on functioning and participation rather than deficit.\n\n## The Pinnacle way\nThis is general classification 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, never from an app or form. Our [child development](/) framework aligns cognitive constructs such as permanence to ICF domains, and where early cognitive or communication support is indicated we may draw on [speech therapy](/speech-therapy) and structured developmental input.\n\n## Trusted sources\nWHO International Classification of Functioning, Disability and Health (ICF) browser for component and chapter definitions; WHO guidance on functioning and disability classification; CDC and AAP/HealthyChildren milestone guidance describing the typical emergence of object permanence in the first
