                                        Abstract
                                        Derived from the embodied cognition hypothesis, image schemas are conceptual primitives thought to capture the
                                        spatiotemporal relationships underlying human conceptualisations. However, many embodied experiences are not
                                        spatiotemporal but rather based on the different sensory modalities. In order to provide a more comprehensive
                                        perspective of conceptual primitives, this paper looks at the traditional five senses and sketches an initial
                                        perspective of how some conceptual primitives could be systematically approached.

                         1. Introduction
                         Embodied cognition proposes that all human thought stems from the embodied interactions with their
                         environment [1]. This is a powerful position as it offers a concrete grounding of meaning and conceptual
                         spaces to the tangible world. However, the cognitive relationship between the “real world” and the
                         mental representation remains unclear even within this theoretical framework.
                            Taking a cognitivist approach, in which the mind is thought to function as an abstract information
                         storage and processor, the embodied experiences must be translated into some cognitive components
                         that can be processed and used efficiently. One possible solution to explain the demonstrated efficiency
                         is to assume that these components take the format of generalised semantic “building blocks”. Such
                         building blocks are likely rich in embodied grounding while having a broader (or vaguer) application
                         format to adapt to particular situations. Motivations of how conceptual information is represented as
                         smaller compositions are found in a range of scientific disciplines including early and highly influential
                         work such as gestalt principles [2], universal grammar [3] and the transcendental schemata [4]. Frege
                         [5]’s principle of compositionally is also important for conceptual primitives, as it demonstrates how,
                         by combining the sense (or meaning) of smaller components, different meanings can emerge due to the
                         particular composition.
                            From the perspective of past discoveries in cognitive linguistics [6] and developmental psychology [7],
                         the representation of the embodied experience is thought to take the format of “image schemas.” They are
                         commonly defined as cognitive patterns that are semantically rich generalisations of early experiences
                         and perceptions. Importantly, they are proposed to be atomic cognitive gestalts that underlie large
                         parts (if not all) of the conceptualisation of the world. Image-schematic notions such as Containment,
                         Link and Source_Path_Goal form relational notions can be found in a range of linguistic expressions
                         as well as abstract representations such as “getting out of a depression” and “life is a journey”. In this
                         fashion, they also capture the functional and descriptive relationships between agents, objects and
                         environments. For instance, it is possible to be “inside a house” or to “be linked to each other through
                         marriage”.

   While there are a different perspectives (likely due to the elusive and hard-to-study nature of the
image schemas), definitions are often based on spatiotemporal experiences grounded in the Euclidean
experience of space and the linear experience of time and how that information can be mapped onto
conceptual structures [8, 9]. However, many sensations and foundations of conceptual spaces are (in
a direct sense) neither spatial nor temporal. Human sensory experiences are rich and are founded
on a range of sensory experiences which may or may not be spatiotemporal. Think, for instance,
of the experience of eating sun-warm strawberries picked directly from the plant. Following the
conceptual framework where spatial and temporal descriptors are applied to conceptual structures,
one might express the taste experience as being “round” in flavour or that it “lingers.” Yet, ultimately,
the experience itself is not of a prototypical image-schematic nature. Properties such as taste, size,
texture and temperature play a larger role in the experience of the situation and using these more
“precise” descriptors would be a more accurate way to capture the semantics of the experience. However,
even without a foundation based on spatiotemporality, it is important to note is that other “sensory
primitives” are still intended to function on a higher level of abstraction and generalisation, just like
the image schemas. In comparison to the systematic work on formally approaching image schemas
(e.g. the previous work by the authors [9, 10]), there is (to the author’s knowledge) no method to
holistically describe the conceptual spaces of the non-spatiotemporal primitives. As a consequence,
many conceptual metaphors are based on image-schematic terms and spatiotemporal relationships.
Thus, relying on linguistic convention and embodied inference as a means to describe the conceptual
experience of the situation.
   Traditionally in cognitive linguistics, this has been used to a posteriori motivate the role image schemas
play in our conceptualisation. By looking at the usage of spatiotemporal metaphors for embodied
experiences we can explain increasingly more complex notions and temporal changes [11]. However,
it is equally interesting to look at the embodied experiences themselves and see how this translates
into conceptual primitives in their own right. The hypothesis is that while image schemas may lay the
foundation for (some) conceptualisation, embodied experiences can be sorted into conceptual primitives
in their own right - simply perhaps with lesser established conceptual spaces.
   Dealing with these non-(obviously-)spatiotemporal conceptual primitives, this paper attempts a
preliminary, high-level analysis of some sensory primitives.


2. Multimodal Sensory Experience and Possible Primitives
One of the main pillars of embodied cognition is that cognition stems from embodiment. Simultanously,
embodiment is based on multimodal sensory experiences [1]. In consequence, the sensory experiences
are what constructs cognitions. Most commonly we speak of five traditional senses, but there are
a number of other sensors and embodied inputs that likely play a central role when constructing a
conceptual understanding of the world. However, as a preliminary starting point, in this paper, we
restrict ourselves to the traditional five senses: vision, taste, olfactory, hearing and touch.
   The experiences from the senses come in a few different forms and structures. Some are heavily
influenced by categorisation and different classification formats. Others act as binary experiences. Yet
others, are more dependent on the context and the individual objects in the scene/experience.

2.1. Vision
Most human experiences are heavily based on vision. A prototypical human visual experience is a 3D
perception of percepts such as shape, colour, size, depth and shades. Out of these, two are particularly
important for the identification of objects: colour and shape.

Colour: Analysing colour as a conceptual primitive is of particular interest when it comes to metaphor-
ical uses. Many expressions rely on colour metaphors to describe certain emotional states. Consider
expressions such as “being green with envy”, “having the blues” or “seeing in red”, all using a colour
                                                    Figure 2: Geon examples.

code to describe an emotional state. Despite being a complicated relationship, there is a documented
semantic connection between colours and concepts and [12] even introduces a conceptual inference
system based on colour associations. While many conventional colour associations are likely culturally
enforced, there is also empirical support that colours results in embodied reactions such as alterations
in blood pressure [13] and simulate hunger [14]. These changes in physiological states further support
the idea that there is an embodied relationship between colour and semantic annotation.
   That colour plays a central role in how we identify objects is clear. We regularly identify objects
based on iconic colours; consider, for instance, bananas, stop signs and marble. It is less clear how it
would be possible to formally define and represent a conceptual primitive based on colours. Using the
primary colours would be too reductionistic and simultaneously neither detailed nor specific enough
to capture the impact of colour. Instead, possible perceptual description ranges from everything to
numerical descriptions as found in web colours - a hex triple representing the primary colours, and
regional representations such as that seen in conceptual spaces [15]. One could imagine a conceptual
space of colours designed based on a 3D matrix based on the RGB colour cube, see Figure 1.

Shape: Not only are prototypical bananas associated with the colour yellow, they are also famous for
their elongated bent shape. For shape and spatial descriptors, many metaphorical and abstract uses
exist. Consider expressions like “getting square with someone” or “why the long face?”, both relying on
shape descriptors. Shapes are also interesting with respect to how they influence our conceptualisation
and emotional reaction to the object itself [16]. As many artists or architects might tell you, the shape
of an artefact influences our perception of the object and its interpretation.
   One highly influential theory for how shapes can be treated as compositional primitives is the theory
Recognition by Parts [17]. This is partially supported by seminal neurological research that shows that
certain cortical columns react to particular shapes and lines with distinct orientations [18]. Recognition
by parts proposes that all objects can be decomposed into a limited set of basic geometric shapes
called geons, see Figure 2. These shapes are things like spheres, cubes and pyramids that in different
combinations and constellations form increasingly complex constructions.
   Geons are strongly connected to the notion of spatiotemporality in that they are so spatial. However,
the interesting thing about them is not how they occupy space in isolation, but rather how they combine
to form larger contexts.

2.2. Taste and Texture
Taste and the experience of food are likely the hardest sense to discuss with respect to reasonably
formulated conceptual primitives. This goes against the importance of it from an embodied perspective,
as the experience of food is both highly embodied and important for meaning attribution in daily life.
                                                                    Figure 4: Texture graph example.
Figure 3: Taste profile example


Taste: Taking a direct approach to conceptualising taste, we have five main proposed flavours: salt,
sweet, sour, bitter and umami1 , that (roughly) correspond to particular nutritional macros or, as in the
case with bitterness, potential danger.
   While we experientially think of an apple as having “apple taste” and mulled wine as one of the
metaphoric flavour of “Christmas”, there is no particular taste receptor that corresponds to things like
apples or Christmas. Instead, all different tastes are a unique combination of chemicals that to different
degrees activate the sensation of the main five tastes. For instance, (guessing entirely) the flavour of
banana might be a combination of 80% sweet, 12% sour, and the remaining 8 spread on salty, bitter and
umami. In comparison, the flavour of a steak might be 95 per cent umami and 4 per cent salty. The
perception of the taste is then reinforced with the identification of what the other senses (primarily
vision and smell) are telling you you are eating.
   Therefore, it is possible to base the taste primitive on a conceptual space consisting of a vector with
5 dimensions for taste where each dimension corresponds to a value of one of the main flavours, see
possible representation format in as a pie chart in Figure 3. It is also possible that the strength of the
flavour plays a large role, which could be interpreted as a higher dimension of the chart.

Texture: While texture is perhaps not a flavour in itself, it plays a central role in the experience
of taste. Interestingly enough from a conceptual direction, there is a correlation between crunchy
and sharp flavours such as sparkling water and Maltesers with hard-sounding letters and words (e.g.
kiki) and with softer flavour/texture sensations like water and brie cheese with soft wounding words
(e.g. bouba) [20]. This is an example of “sound symbolism” which will be mentioned in more detail in
the next section. However, the interesting takeaway concerning culinary texture is that the physical
sensation has a direct relationship with the conceptualisation. There might not be a clear-cut distinction
between textures but it is reasonable to assume that different properties should exist on different axis,
see possible representation format in Figure 4.

2.3. Olfactory
Our sense of smell is likely the hardest sense for humans to understand and finding reasonable conceptual
primitives is a challenge. In some ways, smell is an experience that accompanies, or enhances, taste.
Consider how bland food tastes when you have a cold. In fact, some researchers propose that up to
95 per cent of what you taste, is based on smell [21]. This is great news for the perfume industry but
complicates things from a formal and conceptual perspective.
  Physically speaking, humans are estimated to have some 400 different odorant receptors [22]. This
corresponds to the ability to identify an estimate of up to 1 trillion (!) different odours [23]. This provides

1
    There is also a growing hypothesis that fat corresponds to yet another flavour but it has yet to be empirically ascertained [19].
a remarkably diverse and rich experience compared to taste (especially considering the overall human
preference for eating over smelling). It would be unfeasible to introduce 400 conceptual primitives for
smell, and any methodology for designing primitives that can capture up to 1 trillion different odours
will undoubtedly fail.
    Due to the complexity and vastness of smells, any conceptual approach to model a primitive perspec-
tive on the sense of smell requires a rather complex representation format. Therefore, an ontological
approach is likely the most suitable for grouping the smells into categories. Here the distinctions can be
based on shared perceptual experiences where categories and subclasses of smells can be constructed
based on shared features. For instance, on a high-level one could distinguish between “good/bad” smells
and divide them into subcategories like “floral” and “fruity” that each could contain the individual
smells that prototypically fit within that smell-character. Likely, most smells would fit into more than
one category, constructing a complex network and knowledge graph of primitives and their members.
Some work has been done to introduce such ontologies for odours based on different perspectives. [24]
looks at categories based on perceptual categories, and [25] introduced an ontology for smells. However,
with some 1 trillion smells to be identified any categorical division needs serious consideration. From
the perspective of conceptual primitives, only the upper categories would likely be of any interest.
    It is tempting to disregard the olfactory sense when modelling a framework for embodied conceptual
primitives due to its immense complexity. However, our sense of smell is conceptually important in that
it is highly associated with categorisation through activation of nostalgia and memory retrieval [26],
situational comprehension (consider the smell of smoke and what conclusions one can draw from that)
and even (implicit and explicit) decision making2 .

2.4. Hearing
Similarly to smells, sound is something that entirely surrounds us. Meaning that while we can hear
(and smell) where particular sounds come from, we experience sound from a more regional spatial
perspective. It is also experienced as a scale that changes over time, and there are a lot of spatial
requirements to how we hear things. Consider an echo, how sound is distributed in a concert hall and
the time it takes for thunder to accompany the lightning. Excluding loudness (which can be thought of
as a magnitude scale much like with the intensity of tastes), in an instant, sound waves are exclusively
experienced as tones with pitch.
   One interesting conceptual phenomenon associated with sound is the theory referred to as “sound
symbolism.” Sound symbolism proposes that there is a systematic relationship between the way a word
sounds and its meaning. As mentioned with taste and textures, certain experiences are highly connected
to particular sounds and this is inferred to other domains as well. Consider the sound of glass shattering
and the associated feelings we have when hearing the sound even when there is no glass around.
   Unfortunately, sound symbolism is generally disregarded as scientifically solid. Despite that, there
is research shows some correlations between the perception of sound and the assigned meaning
(e.g [27, 28]). It is simply likely that this relationship is not bidirectional but emerged as a feature of
how language developed from embodied associations. Regardless, the interesting thing about it is that
the phenomenon does support the idea of embodied primitives from a much richer perspective than
previously established.
   Sound primitives are likely to be structured as olfactory primitives: as ontological categories. Many
of the taxonomies of sounds focus on human categories (e.g. [29]). However, for any approach looking
at embodied conceptual primitives, the core features are likely better related to the physical principles
of sound waves stemming from the prototypical features of objects and the sound they produce/reflect.

2.5. Touch
The final sense is the most embodied in that it is the sensation of physical touch. Thus, it feels rather
intuitive to think of touch as rather spatial as an experiential component. After all, the body occupies a
2
    Consider the epic quote from Lord of the Rings, where Gandalf tells Merry: “When in doubt, always follow your nose.”
spatial region and the skin is a form of a curved and connected plane. However, with the exception of
“where” the touch is felt, there is rather little about touch that is directly spatial. Looking at the sensory
receptors on human skin, there are only four main sensations that can be experienced: pressure, hot,
cold, and pain. Pressure has multiple types of sensory receptors but overall is it simply a matter of the
sensation of force on the skin, so here we treat it as one primitive category.

Temperature: The importance of temperature as an experiential conceptual primitive exceeds the
sensation of touch as temperature is something that extends outside of our bodies and “surrounds
us” and is associated with the objects themselves (e.g. tea, snow man and sunshine). In a simple
form, temperature can be represented as a binary relationship3 : either hot or cold, alternatively as the
relational: hotter or colder. In many conceptual situations, temperature does not need to be better
specified. However, from the physical perspective, temperature can also be considered a scale, as in
how we measure temperature with a thermometer. The temperature itself is only so interesting as the
experience of temperature also depends on other factors (that we may or may not be able to detect)
such as humidity, air pressure, wind and shade.

Pain: While perhaps being the most important sense from an evolutionary perspective, pain is actually
rather simple as a conceptual primitive4 . Pain acts as a scale from “a little bit of pain to increasing
amounts of pain.” Other than asking people to self-assess the level of pain, there is really no means
to measure it. It is an entirely internal experience. Interestingly enough, there is no such thing as a
receptor for pleasure.

Pressure: From the perspective of assigning conceptual primitives, pressure is the most interesting
component under touch. This is because of the strong correlation of pressure with forces.
   Taking this perspective, touch primarily appears to be a type of force schema. It is the sensation that
allows us to feel pushed in a direction or the sensation that we experience as we push (or bump) into
something. Developmental psychologist Mandler calls this primitive umph [30]. In recent work [10], we
separated the umph primitive into two variants: a-umph (active) and p-umph (passive), to distinguish
between the situations in which the self is actively causing the sensation of pressure to the body from
the sensation in which an external force is pressured onto the physical body.


3. Compositionality of Conceptual Primitives
Designing a systematic overview of conceptual primitives is interesting in its own right. However, the
greatest benefit lies in the possibilities of what happens when conceptual primitives are combined to
represent a bigger picture.
   Argued to be one of the most influential ideas in linguistics, Frege’s principle of compositionality [5]
proposes that the meaning of a proposition is a combination of the meaning of the parts and how
they are combined. For theorists working on image schemas as the conceptual foundation for events
and conceptualisations, the notion of “image schema profiles” is familiar [8]. These are groupings
of image schematic relationships that take part in the conceptualisation of a particular scenario or
concept. Consider for instance a situation like “going to the beach”. It has a range of image-schematic
components: “going to” is a member of the Source_Path_Goal family [31], the beach is associated
with concepts like “swimming” which can be thought of as being_Contained in water, etc. These
image schema profiles have further been subdivided based on the type of combinatorial process that
is involved [32] and investigated to describe the conceptualisation behind events through conceptual
segmentation [33, 10].

3
  With a possible additional neural state, that is only ever experienced when queried. Consider lukewarm water/air - it cannot
  be felt unless you realise it is there.
4
  Completely disregarding the whole range of emotional pain here.
   While such profiles capture highly semantically relevant components of these conceptualisations
they are far from complete. A situation such as “going to the beach” is also conceptualised based on the
conceptual primitives that are not necessarily spatiotemporal, but rather sensory-embodied: e.g. the
temperature of the sun, the sensation of sand between your toes, the sweetness of ice cream, and the
perceptive experience of objects like beach balls, parasols and bathing suits, and emotional components
like ‘having fun’ or the stinging pain from sunburns.
   A truly representative conceptual space for the conceptualisations of something like “going to the
beach” is required to take a much more holistic perspective into account for it to make the concept
justice. It is only in this complete combination of conceptual primitives that we can learn to understand
that the unique compositions actually tell us about the concepts themselves.


4. Discussion and Future Work
Established conceptual primitives such as the spatiotemporal relationships of the image schemas are
inherently embodied, yet little work has been done to establish the sensor-perceptive primitives from a
multimodal perspective.
   In this short paper, a few possible directions for how to identify and approach conceptual primitives
from the (traditional) five senses have been introduced. While this study does not attempt to solve any
of these issues, nor introduce a complete set of primitives, it is intended as a perspective piece that may
spark inspiration on how such non-spatiotemporal conceptual sensory primitives could be defined,
formalised and utilised in a larger setting.
   Being one of the prominent promoters for image-schematic research to lay the foundation for
conceptual structures, it feels important to point out that this is not intended to replace image-schematic-
like conceptualisations formats but rather to enrich them with more conceptual primitives.
   Passionate about this idea space, future work includes taking a closer look at what different types
of primitive candidates such as those presented in this paper could look like formally and empirically.
The main goal is to approach an ontologically structured formal theory for conceptual primitives that
more holistically can describe the mental components involved in the realisation of thought and the
conceptualisation of experience.
