Objects of Reference: The Complete Teacher's Guide to
Complete guide to Objects of Reference for PMLD and sensory impairment. Learn to choose, introduce and use tactile symbols for effective communication.
Objects of Reference are tangible items used alongside spoken language to represent activities, people, places, or events. For children with profound and multiple learning difficulties, sensory impairments, or significant communication needs, these physical objects provide a concrete way to understand what is happening, what is about to happen, and to communicate their own choices. This approach bridges the gap between the abstract world of words and the concrete world that these learners can touch, hold, and explore.

Objects of Reference: From Concrete to Communication
Effective Object Reference Teaching Strategies
Object Reference Types and Categories
| Object Type | Description | Example Use |
|---|---|---|
| Identical objects | Exact match to the real item | A real cup to represent drink time |
| Associated objects | Items strongly linked to an activity | Swimming goggles for pool time |
| Partial objects | Part of something representing the whole | A piece of towel for bath time |
| Textured objects | Tactile representations of concepts | Rough texture for outdoor play |
What Are Objects of Reference?
Objects of Reference are physical items that represent activities, people, places, or events for individuals with communication difficulties. These tangible objects provide concrete communication support for learners with profound learning difficulties, autism, or sensory impairments. They reduce anxiety and enable choice-making through tactile exploration.
Objects of Reference (OOR) are physical objects that represent something else: an activity, a person, a place, or an event. They are used as a communication system with individuals who have not yet developed, or cannot access, more abstract forms of communication like speech, signs, or symbols.
At their simplest level, Objects of Reference help individuals understand what is about to happen. A spoon presented before lunch signals "it is time to eat." A towel before bathtime signals "we are going to have a bath." The object becomes a predictable cue that reduces anxiety and builds anticipation.
At more developed levels, Objects of Reference can support:
The approach has its roots in work with deafblind children and adults, where tactile communication is essential. It is now widely used with anyone who needs concrete support to understand the world, including learners with:
How Do Objects of Reference Work?
Objects of Reference work by creating concrete links between physical items and their meanings through consistent use and tactile exploration. The learner handles the object whilst hearing associated words, building understanding through repeated exposure. This process develops from simple recognition to active communication and choice-making.
Object-Meaning Connection in Tactile Learning
For most people, words are arbitrary symbols. There is nothing about the word "cup" that tells you what it means. You learned this association through repeated experience.
Objects of Reference create a more direct connection. The cup is not an arbitrary symbol for drinking; it is the actual thing used for drinking. This concrete link is much easier to learn than an arbitrary symbol.
Over time, with consistent use, learners can begin to understand that the object represents the activity, not just that the object and activity go together. This is the beginning of symbolic understanding, which may eventually support the use of more abstract communication systems.
Representation Hierarchy: Concrete to Abstract
Objects of Reference sit within a hierarchy from most concrete to most abstract:
| Level | Example | Abstraction |
|---|---|---|
| Real object used in activity | The actual cup used for drinking | Most concrete |
| Part of real object | A handle from the drinking cup | Slightly abstract |
| Miniature object | A toy cup | More abstract |
| Photograph | Picture of the cup | Abstract |
| Line drawing | Simple drawing of cup | Very abstract |
| Written word | The word "cup" | Most abstract |
Moving up this hierarchy requires significant cognitive development. Many learners with profound difficulties will always need concrete objects. Others may gradually move to photographs or symbols, but this progression cannot be rushed.
The key principle is to start where the learner is and build understanding at that level before considering any move towards more abstract representation.
The Role of Sensory Exploration
Objects of Reference work because they engage multiple senses simultaneously. When a learner handles a swimming costume, they feel the texture of the material, notice its smell from the swimming pool, and explore its shape and size. This multi-sensory experience creates rich associations that support memory and understanding.
For learners with visual impairments, this tactile exploration becomes even more critical. The object provides information that cannot be gained through sight alone. A towel feels fluffy and absorbent. A spoon is smooth and metallic. These sensory qualities become part of the meaning.
Research shows that multi-sensory learning strengthens neural pathways and supports retention. For learners with profound difficulties, this sensory richness may be the primary route to understanding.
Frequently Asked Questions
What are objects of reference in special education?
Objects of reference are tangible items used to represent activities, people or places for learners with significant communication needs. They provide a physical cue that helps children understand what is about to happen next. This approach bridges the gap between spoken words and the concrete world for those who struggle with abstract concepts.
How do teachers introduce objects of reference in the classroom?
Teachers should start with real, identical objects that are actually used in the activity, such as a cup for drink time. The adult presents the item immediately before the activity begins to build a clear association. The learner must be given time to actively hold and feel the object while hearing the associated spoken words.
What are the benefits of using objects of reference for learners?
These tangible cues significantly reduce anxiety by providing predictable routines for children with sensory impairments or profound learning difficulties. They support the development of symbolic understanding, which is the foundational stage for all communication. Furthermore, they allow non-verbal students to make active choices by reaching for or pointing to specific items.
What does research say about multi-sensory tactile learning?
Studies indicate that engaging multiple senses simultaneously strengthens neural pathways and improves memory retention. For learners with visual impairments, tactile exploration provides critical environmental information that cannot be processed through sight alone. Consistent exposure to these concrete physical links is proven to be easier for early learners to process than arbitrary spoken words.
What are common mistakes when using objects of reference?
The most frequent error is a lack of consistency among school staff when choosing and presenting the items. Using miniature toys instead of the actual functional item can also confuse learners who are not yet ready for abstract representation. Finally, adults often rush the interaction, failing to give the child enough time to properly touch and recognise the object.
How do students progress from objects of reference to visual symbols?
Moving to visual symbols requires significant cognitive development and should never be rushed. Educators slowly transition from the real functional object to a part of the object, then to a miniature version, and eventually to photographs or line drawings. This progression must carefully match the individual cognitive readiness of the child.
Classroom Implementation Best Practices
Successful implementation requires careful selection of objects, consistent use across all staff, and systematic introduction following the learner's pace. Start with objects directly used in activities, ensure all team members use identical approaches, and allow sufficient exploration time before expecting recognition or response.
Choosing Appropriate Objects
The most effective Objects of Reference are items actually used in the activity they represent. This creates a natural, logical connection that supports learning. However, practical considerations sometimes require adaptations:
