Eye-Contact
Which ICF Domain Does Eye-Contact Map To?
In the WHO ICF, eye-contact in early childhood maps primarily to the Activities and Participation component, Chapter d7 (Interpersonal interactions and relationships), most precisely d710 Basic interpersonal interactions, where social gaze is named as responding to and initiating contact. It is supported by body-function visual codes (b210) and relates to d335 (producing nonverbal messages), but as a social behaviour it is classified as an interaction rather than a sensory function. The ICF-CY is the appropriate paediatric frame, with qualifiers applied developmentally.
Eye-contact is one of the earliest social signals a child offers — and in the ICF it lives squarely within the architecture of interpersonal interaction.
In short
In the WHO International Classification of Functioning, Disability and Health (ICF), eye-contact in early childhood maps primarily to the Activities and Participation component, within Chapter d7 — Interpersonal interactions and relationships, most precisely under d710 Basic interpersonal interactions (which explicitly includes responding to and initiating social contact through gaze). It is also supported by body function codes for visual functions (b210) and attention/orientation, but as a social behaviour it is classified as an interaction, not merely a sensory function. The ICF-CY (Children & Youth version) is the appropriate frame for paediatric coding.The classification logic
The ICF separates body functions and structures from activities and participation. Eye-contact recruits visual function (b210) and could touch on social-emotional functions (b122, global psychosocial functions), but the act of using gaze to engage another person — to share attention, to regulate a turn, to initiate or respond to contact — is a relational activity. Hence its natural home is d710 Basic interpersonal interactions, with relevance extending to d335 Producing nonverbal messages (gaze as communicative signal) and, as the child matures, to d7600 Parent–child relationships and broader participation domains. Coding gaze under d7-series rather than the b-series preserves the ICF's biopsychosocial intent: function is described through real-world interaction and environmental context, not in isolation. For early childhood, qualifiers are applied developmentally — gaze behaviours are interpreted against expected emergence (responsive social gaze from the early months, with referential and triadic gaze maturing across the first two years).Why this mapping matters in practice
Framing eye-contact as an interaction rather than a deficit of a body part directs assessment and support toward the child's communicative repertoire and the responsiveness of their environment — caregivers, play partners, settings. It aligns measurement with participation goals rather than isolated skill drills, which is the clinically meaningful unit for early social-communication development.The Pinnacle way
This is general classificatory information, not a diagnosis — a clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care, never from an app or form. Our clinicians map gaze and joint-attention behaviours within a structured developmental profile, drawing on speech therapy and social-communication support, and you can explore the framework further at our [resource hub](/). The structured assessment is administered by a qualified clinician.Trusted sources

What to watch
Whether gaze is being used relationally — to respond to, initiate or share contact with another person — rather than assessed only as visual acuity; this distinguishes a d7-series interaction code from a b210 visual-function code.
Try this at home
When observing gaze, note the social context: is the child using eye-contact to share attention, take a turn or signal interest? That relational use is what the ICF d710 domain captures.

Frequently asked
Is eye-contact an ICF body function or an activity?
It draws on body functions such as visual functions (b210), but as a social behaviour used to respond to or initiate contact with others, it is best classified within Activities and Participation — Chapter d7, specifically d710 Basic interpersonal interactions.
Should I use the ICF or the ICF-CY for a young child?
For early childhood, the ICF-CY (Children and Youth version) is the appropriate frame, as it provides developmentally sensitive content and qualifiers for paediatric functioning.
Does eye-contact relate to any other ICF codes?
Yes — it relates to d335 Producing nonverbal messages (gaze as a communicative signal) and, as the child matures, to relationship codes such as d7600 Parent–child relationships, alongside supporting visual-function code b210.
