Layer 1: Inputs: The Hidden Dimensions of Sensory Perception

According to Dr. Aron, a characteristic of highly sensitive children is their sensory processing sensitivity. Sensory processing sensitivity is proposed to be an innate trait associated with greater sensitivity to environmental and social stimuli (Aron et al. 2012)[i].

Beginning to discuss highly sensitive children health means understanding what a heightened sensory or other kinds of heightened experiences are and how they influence the way a child perceives the world and his/her identity. In the case of highly sensitive children, the environment and social stimuli play a crucial, yet invisible, role in their identity formation and affects their behaviours to a much greater degree than other children. Given that spatial embodied knowledge is vital to the identity formation and sensorial experiences of highly sensitive people, we will begin by examining the hidden nature of space at a molecular level.

As we saw in chapter 5, everything that exists is made of energy, including us. In the article “what exactly is Higgs-Boson”, Jonathan Atteberry explains that the standard model of Modern particle physics has articulated that the universe doesn’t only contain matter; it also contains forces that act upon that matter. Along with particles, the standard model also acknowledges four forces: gravity, electromagnetic, strong and weak. As it turns out, scientists think each one of those four fundamental forces has a corresponding carrier particle, or boson, that acts upon matter.

“ Some physicists have described bosons as weights anchored by mysterious rubber bands to the matter particles that generate them. Using this analogy, we can think of the particles constantly snapping back out of existence in an instant and yet equally capable of getting entangled with other rubber bands attached to other bosons (and imparting force in the process).

 Scientists think each of the four fundamental ones has its own specific bosons. Electromagnetic fields, for instance, depend on the photon to transit electromagnetic force to matter. Physicists think the Higgs boson might have a similar function — but transferring mass itself.”[ii]

Assuming the Higgs boson exists, everything that has mass gets it by interacting with the all-powerful Higgs field, which occupies the entire universe. If these forces are what bind the world together, the nature of matter itself has been redefined. Physicists now understand that particles have no inherent mass, but instead gain mass by passing through a field.

If the Higgs field generates energetic forces that are invisible to us, it is still the essential nature of space. One can assume this Higgs field functions similarly to other energy fields we know of, such as electricity.

As Bernie Hobbs explains[iii], an electric charge always has an electric field around it, spreading out forever. If an electric charge moves, the electric field will move with it. No matter what speed the charge is moving at, its electric field will follow it at the speed of light, but it takes a tiny fraction of time for the whole field to catch up. If you make the charge move up and down (or side to side, or back to front) in a nice steady rhythm, the electric field around it forms waves – like the ripples on a pond – moving out in every direction at the speed of light. Whenever an electric field moves, it automatically creates a magnetic field that mimics its moves but at a 90 degree angle. The electromagnetic field travels as a wave just in the same way as light does.

Magnetic fields can control other forms of energy. Researchers at The Ohio State University have discovered how to control heat with a magnetic field. The study is the first ever to demonstrate that acoustic phonons — the elemental particles that transmit both heat and sound — have magnetic properties:

This adds a new dimension to our understanding of acoustic waves,” said Joseph Heremans, Ohio Eminent Scholar in Nanotechnology and professor of mechanical engineering at Ohio State. “We’ve shown that we can steer heat magnetically. With a strong enough magnetic field, we should be able to steer sound waves, too.” (…) “We believe that these general properties are present in any solid,” said Hyungyu Jin, Ohio State postdoctoral researcher and lead author of the study”.[iv]

If all energy has magnetic properties, it must be present in humans in some way. Our body generates electricity, and this ability is actually a key part of your achieving health. Electricity allows our nervous system to send signals to our brain. These signals are electrical charges that are delivered from cell to cell, allowing for nearly instantaneous communication. The messages conducted via electrical signals in our body are responsible for controlling the rhythm of our heartbeat, the movement of blood around your body, and much more.

We are electrical beings and as such, we also create magnetic fields. We know that an electromagnetic field affects the behaviour of anything with charge in the vicinity of the field. The image below illustrates the invisible signature of a magnetic field. It is quite plausible that the Higgs field produces a similar invisible effect.

These findings suggest that we are made of energy and forces, not matter, and that we are forces that exist in a field of energies and interact with other fields of energy. Highly sensitive children are more sensitive to the signals of these fields and perceive their subtleties in great detail. These energies are the fundamentals of sensory communication.

Given their heightened ability to process subtleties, we should consider the quality of external influences as central to the “self” formation of highly sensitive children. While the processing of sensory input is internal, the inputs themselves are external elements. Energy emanates from all sentient being, as such it is important to understand the quality of energy people and the world bring to these children.

Since space is central to sensory life and that energy is core to space, the most fundamental element of sensory life is energy. We need to consider that a highly sensitive child’s “being” is intertwined among many dimensions in interactions with energy which have a subtle effect on the child; and that their well being depends in part on balancing the inter-relationship of energy to a number of other health determinants.

Here lies a first difficulty; energy is the most difficult element to consider as it is invisible and depending on our belief systems (the social and cultural perspectives), it has more or less defined boundaries. This explains why understanding the nature of a highly sensitive child’s sensory experience is often difficult, what is sensed may not be obvious. But if we can help them to understand these boundaries by rendering them explicit, highly sensitive children may be able to recognize where the edges of their being begin and stop. With awareness of their existence in space, they may stop confusing themselves with the environment, a rather difficult situation, also detrimental to identity formation and sure to create tremendous anxieties. We will come back in greater details the nature of this spatial dimension of health and its implications on a child’s behaviours later on. First, it is important to understand the unique way in which a child’s spatial experience of the world influences his/her perception of life and influence a highly sensitive child’s health.

HSC’s Holistic Experience of the Environment: Identity and Sensory Experiences of Spatial and Social contexts

Interestingly, the quadrivia approach, that we saw earlier, reinforces from a theoretical perspective what aboriginal culture already articulated: a child exists in a social context, a family, a community and the world. Adapted from Cindy Blacksock’s aboriginal health model, which we explored in chapter 5, the figure below shows these influences.

Figure 6: Experiential Environment Influences


These elements constitute the immediate environment (E) of a child and are the first items that will be sensed or experienced by a child and as a result have a direct impact on his/her sense of self. This environment is built upon matter, energy and force fields (e) emanating from all these elements. While their influence can be undetectable, nevertheless, they have an incredible impact on a highly sensitive child sensory health. These elements are intertwined, operating simultaneously on the senses, thus the use of circles to represent each field of influence, affecting and reacting to each other. These fields of influences shape a child’s experience of the world and as a result unconsciously forge his/her perception of reality and self. A highly sensitive child through his/her own spatial awareness perceives these varied sensory dimensions.

A person can obtain a deeper level of awareness by becoming familiar with these fields of perception using the quadrivia approach:

“Through his use of different aspects of his own awareness, or through formal methods based on these dimensions of awareness, he is able to encounter these different realities in a direct and knowable fashion. In brief, he has direct access to experiential, behavioural, cultural, and social/systemic aspects of reality because these are actual dimensions of his own existence. This is useful to him because it empowers him to notice, acknowledge, and interact more effectively with his world. In short, the more of these “channels” he has open the more information he will be obtaining about what is happening around him and he will be able to feel and act in ways that are timely and insightful. Notice right now how you are engaged in all three perspectives: first-person (e.g., noticing your own thoughts as you read this), second-person (e.g., reading my words and interpreting what I am trying to convey), and third-person (e.g., sitting there aware of the light, sounds, and air temperature around you). Do you see how you are always experiencing the world from all four quadrants—right here, right now? It is that simple.”[v]

The rest of this section explores these perspectives. Let’s begin with a child’s “first person” experience.

The Highly Sensitive Child: A Deeply Spatially Interconnected Holistic Being

According to Dr. Arthur Aron and his team, humans characterized as HSPs are genetically predisposed to show heightened awareness to subtle stimuli, process information more thoroughly, and be more reactive to both positive and negative stimuli. In contrast, the majority of people have comparatively low SPS and pay less attention to subtle stimuli, approach situations more quickly and are not as emotionally reactive.

In “The Highly Sensitive Brain: An fMRI study of Sensory Processing Sensitivity and Response to Others’ Emotions,” Drs. Aron and colleagues used fMRI brain scans to compare HSPs with low SPS individuals. The analysis is the first with fMRI to demonstrate how HSPs’ brain activity processes others’ emotions[vi].

It is clear that this heightened sensory capacity is central to the nature of highly sensitive children’s emotions, self-identities, and beliefs system. Their cognitive, psychological and experiential perceptions of life are deeply rooted in these heightened sensory perceptions. This ability to read subtleties implies that highly sensitive children experiences are holistic.

One of the most common distinctions in the literature on cognitive style is between analytic and holistic styles. Analytic thinking involves understanding a system by thinking about its parts and how they work together to produce larger-scale effects. Holistic thinking involves understanding a system by sensing its large-scale patterns and reacting to them. A holistic person does not tear things apart mentally, to understand them. Instead, the holistic person tends to approach a subject by trying to understand its gist or general meaning. Their ability to get a general feeling about a situation may open their minds to subtle nuances of complex situations (Dewey)[vii].

Analytical thinkers may focus on what a person says to understand how they feel, a process regulated by cultural and social norm, but holistic thinkers operate differently. They read the subtlety of another person’s energy and body language to gage their emotions. This makes them also highly empathic.

An Empathic Experience of the World

Neuroscientists use the term “Theory of Mind” to define the ability to infer other people’s mental states such as intentions or desires. Theory of Mind can be differentiated into affective (i.e., recognizing the feelings of another person) and cognitive (i.e., inferring the mental state of the counterpart) subcomponents (Bodden, 2013)[viii].

It is becoming increasingly evident that our cognitive and affective states are influenced by our senses but are processed differently. The cognitive and affective aspects of theory of mind share the same local patterns of activity in the posterior temporal cortex. The posterior temporal cortex allows us to derive meanings from sensory input for the appropriate retention of auditory and/or visual memories, language comprehension, and emotion association (Smith, 2007)[ix]. In other words, cognitive and affective theory of mind both call upon the area of the brain that is involved with processing sensory input.

Nonetheless, the cognitive and affective aspects of theory of mind both do not use the medial prefrontal cortex in the same way (Corradi-Dell’Acqua, Hofstetter and Vuilleumier, 2013)[x]. The prefrontal cortex is involved in planning complex cognitive behaviour, personality expression, decision-making, and moderating social behaviour (Yang and Raine, 2009)[xi]. The basic activity of this brain region is considered to be orchestration of thoughts and actions in accordance with internal goals (Miller, Freedman and Wallis, 2002)[xii], it is the of the brain involved in analysis, behaviour regulation and attention.

Interestingly, destruction of the orbital (frontal) lobe results in inappropriate social behaviour. What if, highly sensitive children’s empathic thinking and feelings bypass the area of the brain that moderates social behaviour? Some research points towards this idea.

Neuroscientists have demonstrated that empathy represses analytic thought, and vice versa. When the brain fires up the network of neurons that allows us to empathize, it suppresses the network used for analysis (Case Western Reserve University, 2012).[xiii] There is evidence of separate neural pathways activating reciprocal suppression in different regions of the brain associated with the performance of “social” and “mechanical” tasks (Jack et al, 2013) [xiv].

Our brain is triggered and responds to the inputs it receives from the external world, and, depending on the person, sends or suppresses signals that influence the behaviour of a person. It would seem that a majority of people, what we call neuro-typical, have developed the ability to suppress empathy in favour of analytical though; while highly sensitive people can not. On the contrary, in their case such a suppression is damaging to their well being.

Both holistic and empathic thinking are intuitive processes that bypass cultural and social norms of communication. When a holistic and/or empathic thinker is unaware of this distinction, he/she may not be able to reconcile this intuitive reading with the dominant cultural and social analytical communication conventions and, confused by the disjunction between what is said and what is felt and seen, become out of sorts.

Instead of assuming all children follow the same psychological development path, the fundamental foundation for highly sensitive children should be their “unitive” sensory experiences. In other words: their “present-centered” flow of awareness within their environment should be considered the foundation of their psychological development.

But in ego-centered theories, such as Loevinger’s (1976)[xv] theory of ego development, a unitive skill is the highest level of ego development while for highly sensitive children, these skills are paradoxically central to their first levels of personality, the Pre-conventional development, which is marked by low impulse control and fear of punishment.

This could explain the rise of autism and adhd diagnoses. As our culture becomes more repressive, children, often very sensitive until a certain age, become overwhelmed and develop brain patterns that block out the disjointing input (autistic associated behaviours) or need to loose control to let the discordance out of their body (adhd associated behaviours) since, at this stage, they have low impulse control and fear punishment.

There lays another challenge, addressing high levels of development in certain areas within a highly sensitive child’s mind that is still, in many aspects, in its infancy. The more heightened their unitive skills are, the more asynchronic their development may be in other areas and the more difficulty they may have adapting to cultural learning. A potentially very damaging situation when faced with school that tend to require all children to mature in the same areas at a similar rate and a medical culture that is based on synchronic developments and a normative approach to what is health.

As we saw in chapter 1 and 4, in addition to their holistic and empathic perceptions, the boundaries of highly sensitive children’s self are not confined to their body, rather they are first defined by their position in space. Hence, we must think of their being in a different way, one that is influenced by the hidden dimension of the environment and be prepared for them to have a different development scales. Their development scale should consider spatial, empathic and holistic sensing as the foundation of their being. Instead of an ego-based model, a sensory-based model should be developed for each child.

Self-Aware, stage 5 of traditional ego development, is the stage of development where children can begin to understand and articulate the nature of their sensory reactions. As an individual moves from Pre-conventional development towards conventional development they need to understand personal differences and, with age, become more tolerant in order to achieve Self-Awareness. Instead of focusing on analytical skills, highly sensitive children should be encouraged to develop their sensory skills and in time become analytical within a sensory reality of the self.

If we accept that, as holistic and empathic thinkers, highly sensitive children’s development process is different from Neurotypical children, we can help highly sensitive children become aware of the differences in process. A child could then begin to use this understanding and learn how to analyse his or her thinking and sensations and learn to respond in a language and behaviours appropriate for the specific social/cultural group and context.


How a child react to environmental and other types of stimuli is individual. Responses depend on the type of personality the child has. Integral theory can help understand what needs to be considered through its notion of types. These are the variety of consistent styles that arise in various domains and occur irrespective of developmental levels. We can think of types as the different personality or temperament traits highly sensitive children can have; those who are introverted, those who are extroverted, those who get over-stimulated, those who get under-stimulated, those who are sensory seekers, and those who are sensory defenders. All these children have heightened sensory processing capacities, this regardless of the type of stimuli they are reacting to; but they bring their unique temperament or “personality styles” to their responses to stimuli. Types have expressions in all four quadrants (see Figure below).

Figure 7: illustrations of Personality Types

This illustration of types designed by Sean Esbjörn-Hargens allows incorporating the various dimensions related to personality we explored in chapter 3. Internally, an individual has a specific personality type and also a gender type. In general, individuals have access to both masculine and feminine qualities and thus tend to have a unique combination of traits associated with each type. A child is also influenced by a collective type of religious system that influence his/her understanding of reality as well as the meaning of sensory experiences, and different types of kinship systems (e.g., Eskimo, Hawaiian, Iroquois, Omaha, Sudanese), the later regulates the genetic make up as well as cultural norms of that child and potentially regulate his/her nutrition needs.

Externally, each child has a blood type (A, B, AB, O) and a body type (ectomorph, endomorph, mesomorph) these two types can be presumed to influence the chemical and sensorial reactions of a child to the world. In terms of external environment, each child exists in a specific ecological biome types (e.g., steppe, tundra, islands) and may have specific environmental sensorial needs (needing cold or hot temperatures, a certain type of natural stimuli, etc) and governmental regime types (e.g., communist, democracy, dictatorship, monarchy, republic) or social rules, which regulate the nature of sensory experiences, that are acceptable.

Types are stable and do not change, by becoming more aware of them and their role in a child’s sensory health, we could infuse sustainability into our efforts by tailoring them to the unique patterns of a child. For instance, considering introversion and extroversion can help us to shape what would be an appropriate sensory experience for a child.

These internal attributes all inform the “first-person” perspective of a Highly Sensitive Child. They will also influence the other two perspectives, the second-person and third-person perspective. There are many types of sensory experiences that can influence a child (figure below).

Figure 8 illustrations of Sensory Experiences


While the list is not exhaustive, it may help a parent begin to observe during which of these experiences a child changes behaviour. Some of the most obvious are physical (bodily and biological) experiences, which relate to the “first-person” perspective. But in addition, there are mental (emotional, empathic and cognitive), social, spatial, temporal and mediated experiences. Each is informed by specific senses as is outlined in the figure below.

Figure 9 Relationship of Sensory Experiences to Specific Senses


According to the quadrivia approach, the second person perspective relates to how we absorb external experiences while the third-person perspective relates to our sensory awareness during these experiences. Before we can explore how a child’s “second-person” perspective is influenced by how he or she experiences the social and cultural environment, it is important to understand what is a sensory experience itself.   But these sensory experiences are more or less acknowledged by our culture depending on the way we define the senses.

The next section will therefore focus on the senses themselves and how cultural and social regulations of our definitions of the senses influence our perceptions of sensory experiences. In other words, we will focus on the collective/external dimensions of sensory reality.
