Ideasthesia (alternative spelling ideaesthesia) is defined as a phenomenon in which activations of concepts (inducers) evoke perception-like experiences (concurrents). The name comes Ancient Greek ἰδέα (idéa) and αἴσθησις (aísthēsis), meaning “sensing concepts” or “sensing ideas”. The main reason for introducing the notion of ideasthesia was the problems with synesthesia. While “synesthesia” means “union of senses”, empirical evidence indicated that this was an incorrect explanation of a set of phenomena traditionally covered by this heading. Syn-aesthesis denoting also “co-perceiving”, implies the association of two sensory elements with little connection to the cognitive level. However, according to others, most phenomena that have inadvertently been linked to synesthesia in fact are induced by the semantic representations. That is, the meaning of the stimulus is what is important rather than its sensory properties, as would be implied by the term synesthesia. In other words, while synesthesia presumes that both the trigger (inducer) and the resulting experience (concurrent) are of sensory nature, ideasthesia presumes that only the resulting experience is of sensory nature while the trigger is semantic. Meanwhile, the concept of ideasthesia developed into a theory of how we perceive and the research has extended to topics other than synesthesia — as the concept of ideasthesia turned out applicable to our everyday perception. Ideasthesia has been even applied to the theory of art. Research on ideasthesia bears important implications for solving the mystery of human conscious experience, which according to ideasthesia, is grounded in how we activate concepts.
What Is “Ideasthesia” And Why Is It Important To Know?
by Faena Aleph
Many of us speak metaphorically when we describe a color as “screaming” or a sound as “sharp”, These are synesthetic associations we all experience, whether we know it or not ––but we pronounce them literally because it makes enough sense to us.
But synesthesia, which is one of the most charming sensory phenomena, has been overly studied and illustrated by many artists. Today, however, a fascinating aspect of this bridge between senses is being discovered: ideasthesia.
Danko Nikolic, a brain researcher from the Max-Plank Institute, has proposed this theory that questions the reality of two philosophical premises 1) the mind and body, and 2) the perception of senses and ideas. His research suggests that, for starters, these dualities might not exist.
Widely speaking, ideasthesia is a type of bridge that metaphorically links rational abstractions, i.e. ideas with sensory stimuli in a dynamic catalyzed by language. Nevertheless, the best way of understanding “ideasthesia” is through a TED talk that Nikolic himself recently gave. And, be warned, his theory might just change your paradigms from their foundation and reinforce the beliefs that Walt Whitman anticipated over a hundred years ago.
Ideasthesia — Art, Genius, Insanity, and Semiotics

…the notion of ideasthesia — that one can feel or physically experience an idea. Instead of a letter or a sound or a single word as being physically felt, an entire idea or construct or abstract is experienced phenomenologically.
But this seems abstract in and of itself, right? Like, what would it mean to ‘feel’ an idea? The classic example, linked to here, would be to imagine two shapes. One is a curvy splatter, kind of like the old 90s Nickelodeon logo, and the other is an angular, jagged, pointy sort of shape. Which would you call Kiki and which would you call Bouba?
An overwhelming majority (95% according to one source) would say that the splatter is Bouba and the pointy thing is Kiki.
But why though?
Bouba and Kiki are random sounds, absolutely meaningless and the figures were similarly meaningless. Some contend that it is a linguistic effect, since ‘K’ is an angular letter and ‘B’ is more rounded. Yet, there seems to be a consensus on which is which, even cross-culturally to some extent. Because just the idea of the pointy shape feels like a Kiki and the blobbier shape feels like a Bouba.
Another way I think it is felt is when we talk about highly polarizing topics, often political or religious in nature. In the podcast You Are Not So Smart, David McRaney talks about being confronted with a differing view point as having a gut-wrenching, physical effect on him. Researchers pointed out that the feeling is so strong that it actually elicits a fight-or-flight response.
But it’s just words, right? It’s not like someone saying “I don’t believe in universal healthcare” or “You should have the right to pull the plug in a coma” actually makes it so, or will cause it to happen to you. It is simply one person’s thought, so why does it trigger such a deep-seated emotion? The researchers in the episode hypothesize that the core ideas are related to you identity which is being threatened, but I think the explanation is somewhat simpler and stranger.
It’s because the ideas actually feel dangerous to you.
This is why what feels perfectly rational to you feels irrational to others.
It also makes more sense when talking about geniuses or highly gifted individuals. Although they exist, the Dr. House-type hyper-rational savants aren’t usually what you hear about when you look at the biographies of highly intelligent or gifted peoples. Da Vinci, Goethe, Tesla, Einstein and others all seem to describe an intensely phenomenological approach to creating their works.
Even in what is traditionally considered to be more rational pursuits, like math, have occasional introspective debates about whether string theory or higher order mathematics is created or discovered. This seems like a question about whether one feels out a thought or collects and constructs evidence to make a case.
What’s more is that, while I think most people can feel an idea to some extent (kiki vs bouba), gifted peoples and geniuses are more sensitive to these ideas and can thus navigate it better. Sensitivity seems to really be the hallmark of gifted individuals, so much so that I remember reading about how some gifted students have to wear special socks because the inner stitching was too distracting.
I remember when I was younger (around elementary school) there was a girl who was in our schools gifted program who everyone could not stand. She seemed to have a hairline trigger and would snap at just about anything. I realize now that she was simply incredible sensitive to other children and didn’t really know how to handle it maturely.
I can imagine if this sort of sensitivity applied to ideas and thought processes might actually be a big reason why geniuses can handle seemingly large and complex thoughts that are a struggle for the rest of us — they aren’t just thinking through it, they are also feeling their way through it.
It may offer insight into the oft-observed correlation between madness and intellect. Maybe that’s what’s really going on in schizophrenia. It’s not just a disconnect of thoughts, but an oversensitivity to the ideas that breed those thoughts that elicits instinctive, reactionary emotions much like our fight-or-flight responses to polarizing thoughts. The hallucinations are another manifestation of the weaker sensory experience of benign symbols and thoughts.
