Representational Systems
In NLP, representational systems are the sensory channels — seeing, hearing, feeling and related senses — through which people are said to code experience.
Also called VAK, VAKOG, sensory predicates, visual auditory kinesthetic.

What representational systems mean in NLP
NLP practitioner literature describes experience as being represented in sensory systems. The usual teaching set is visual, auditory and kinaesthetic (VAK), sometimes extended to olfactory and gustatory (VAKOG). Predicates — words such as see, hear, feel — are treated as clues to which system is in use in a given moment.
That is a practitioner coding scheme. It is not the same as a complete scientific model of perception, and it is not a personality test that sorts people into “visuals” and “auditories” for life.
How they are used
Trainers often ask students to notice predicates in speech, to match a listener’s current language, and to ask for missing sensory detail. Those channels are also how a state is often described in the moment — what someone is seeing, hearing or feeling now. Calibration is the check on whether that description matches what is actually visible. In rapport work, matching predicates is taught as one form of pacing. In modeling, a modeller may ask what someone sees, hears or feels when a skill is happening.
Submodalities are finer distinctions inside a system: how close a picture is, how loud a sound is, where a feeling sits.
Example
A colleague says, “I just can’t see how this plan works.” An NLP-informed listener might ask what they would need to see in order for it to make sense — a sketch, a timeline, a success picture — rather than answering only with abstract reassurance. The question can be useful. It does not prove that the colleague is a “visual person”.
Common misunderstanding
People have one preferred system that never changes. Practitioner teaching often talks about preferences in a context. Treating VAK as a fixed type, or as a learning-style law, goes beyond what this site will repeat as fact.
Limits
Overlap with ordinary ideas about seeing, hearing and feeling does not validate every later claim attached to the model. Eye-accessing cues — the teaching that glance direction reliably reveals whether someone is remembering or constructing pictures, sounds or feelings — are a later NLP claim. This site treats them as a disputed practitioner construct, not as an established finding, and does not teach them as a technique. Speed-reading minds and guaranteed influence are outside the standard. See Evidence and criticism and What Is NLP?.

- Neuro-Linguistic Programming
Neuro-Linguistic Programming is a practitioner field, originating in the 1970s, that studies how language, attention and behaviour patterns relate to subjective experience.
- Submodalities
In NLP, submodalities are the finer qualities of a remembered or imagined experience — such as brightness, loudness or location of a feeling — used as a teaching frame for how people code intensity.
- Rapport
In NLP, rapport is a working relationship of attention and responsiveness; it is practised through pacing, listening and calibration rather than through forced friendliness.
- Calibration
In NLP, calibration is the practice of noticing specific, present-time sensory evidence of another person’s state rather than relying on a story about what they “must” be feeling.
- States
In NLP, a state is a person’s current organisation of physiology, attention and feeling — the condition in which a behaviour is more or less available.
- Modeling
In NLP, modeling is the process of studying how someone produces a useful result, then making the pattern explicit enough to practise or teach.
