Introverted Sensing according to Aushra Augustinavichiute

We view an object’s internal state as a relation between events that condition each other. Through this element one perceives information about the way processes affect the internal state – one’s feelings and sense of wellbeing that this interdependence causes.

Interaction in space is nothing more than a reflection of one object in another. Objects reflect each other and evoke certain feelings in one another. An individual perceives direct outside information as feelings evoked by things happening around them. For example, a feeling of pain is nothing more than the brain’s reflection of a relation between one’s body and a process taking place in some part of the body and interfering with its functioning.

When this aspect of perception is in the leading position, the individual is able to change the properties of the environment and the way people in this environment feel. They know how to avoid physical discomfort and how to protect others from it, which is determined by an ability to recreate once experienced aesthetic feelings. An excellent example of this is Peter Paul Rubens, who did not paint from life, but rather from his own memory of once experienced aesthetic feelings. When he was making a painting, he sought to give the viewer a specific aesthetic experience by recreating it. Such art is a revival of the object that provides the viewer with aesthetic feelings intended by the creator. Likewise, when an individual with this type of IM is cooking, they start by imagining how the dish will taste. Such people can distinguish once experienced aesthetic feelings from new ones, and know how to collect and remember them. This is probably why there are a lot of people with this type of perception among the so-called “psychic diagnosticians.”

An individual with this type of IM is able to set their sensory aesthetic needs in opposition to the same needs of others. They know how to fight for the fulfilment of said needs, and can shape and refine their own and other people’s aesthetic tastes and habits. They have an ability to impose their understanding of aesthetics and comfortable life on others.[1]

Introverted Sensing according to WSS

Aspect: Physical flow. Physical objects bear a relation to each other in terms of occupying a physical environment. This environment is where things happen, flowing from one state to another in the present moment. The flow is best in quality when smooth and allowed to happen naturally, removing blockages and sudden interruptions that feel painful or grind the gears. Similarly, people can acclimate themselves to the flow, existing in harmony with themselves and their surroundings.

Metabolism: The individual attunes themselves to the flow of events in the present moment, feeling the surroundings in detail with their five senses and helping to maintain its smooth, organic and healthy quality. Anything painful or unpleasant that causes stress or damage to the flow is brushed away, with the intention that things are allowed to happen in the way that is most natural and feels good for them. In this way, the present flow is refined in its feel and quality, creating relaxing, immersed experience of the day-to-day.

Strength: The person is good at noticing and recognising small changes and alterations to the flow of physical experience, being able to pick out each detail contributing to and hindering it, while understanding what needs to go to restore quality. They know from looking at things in the moment, that they are all right and good, not needing any intervention, and that they can simply relax, allowing things to continue. Consequently, the person knows how to savour and enjoy their experiences, without doing anything.

Value: The person desires flow in their present experience, trying to keep the sensations that feel best for them. They want things to be pleasant and non-abrasive, for people to be allowed to do what they will and for past wrongs to be forgiven if no longer causing pain, and for their actions to be in peace and harmony with the life around them. The person tries not to disrupt things that are happening naturally, preferring to go with the flow and enjoy what happens. Similarly, they may withdraw from environments where they feel there is too much disruption to the flow.[2]

Introverted Sensing according to SHS

Tastes, colours, smells, touches; conformity, adaptation; enjoying the moment; skin and mucous membranes.


Intellectual activity in the S-state is the processing of signals coming from all senses. In the S-state, a person absorbs information from the outside world–sounds, smells, touches, temperature–and compares them with each other as a unified sensory complex. The difference from the F-state is that the emphasis is on the dynamics of sensations–on whether they are amplified or weakened, harmoniously combined or arise at random. In the S-state, a person does not think in terms of words or pictures, but through their whole bodies.


Stable expression of S leads to an informal role that is called a task finisher, or a decorator. Such a person shows themselves well when the external environment, perceived through the senses, is in a harmonious state. The S-type avoids activities that are accompanied by discomfort, noise, coercion, and prolonged exertion. Therefore, the task finisher is active in an isolated environment of the society. Although their activity is limited, it is universal and quite diverse–monotony and repetition are disagreeable with the S-state.


The S-state is experienced as pleasure, enjoyment, feeling sated, satisfying one’s thirst and hunger. In the S-state, a person expresses their feelings through giving care, an assistance to satisfy biological needs. This process can be compared to capturing an image on a photographic film, drawing a picture on a piece of paper, recording sounds on a magnetic tape, etc. The S-state can easily diagnose a condition: it allows you to determine the location of pain in the body and its intensity. The S-state is cyclical in nature–filling out and emptying of hollow organs and vessels with a circulating substrate.


The S-state is recognized by a soft and relaxed body, a comfortable position in which body skin is in maximum contact with a supporting surface. In the S-state, uniform physiological processes in the body become quite noticeable–respiration, blood circulation, radiation of heat. Gestures are sparse and precise, but smooth and without tension. Facial expressions are associated with engagement of the taste muscles located around the mouth and nose. Satisfaction or displeasure, pleasure or disgust are painted on the face.[3]
