The therapeutic principle is simple: make the hidden object **salient, predictable and rewarding to recover**, then systematically reduce visual and temporal cues so the child holds the object in mind for longer. Most children consolidate this between roughly 8–12 months, so techniques are matched to current functioning rather than chronological age.\n\n## The techniques that help\n- **Partial-to-full occlusion grading** — begin with a desired toy half-covered by a cloth, prompt the reach, then progress to full covering. Reduce prompting as the child initiates the search.\n- **Errorless hiding** — hide consistently in one location first, reinforcing every successful retrieval, before introducing A-not-B reversals and multiple locations to challenge working memory.\n- **Salient, motivating targets** — use noisy, lit or favourite objects so the auditory/visual trace sustains the mental representation while sight is removed.\n- **Peek-a-boo and social routines** — face-disappearance games scaffold the same concept with strong affective reward and joint attention.\n- **Delay manipulation** — gradually lengthen the interval between hiding and searching to strengthen representational memory.\n- **Containers and posting toys** — putting objects in and out of opaque boxes embeds the concept in functional, repeatable play.\n\nEmbed practice in natural routines and pair with naming (\"where's it gone?\") to link the skill to early language and cause-and-effect.\n\n## The science\nObject permanence reflects emerging representational memory and is a foundation for symbolic play, joint attention and early language. Graded, reinforced search tasks operationalise this within a play-based developmental frame.\n\n## The Pinnacle way\nAbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an app or form. Our therapists profile cognitive-play skills precisely (see [the AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated)) and embed targets in [occupational therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate) and play-based sessions.
