What is Schizophrenia?

Most people have heard the term schizophrenia. It’s a mental health pathology wherein people interpret reality abnormally. To oversimplify to make a point, in a ‘normal’ brain, the left and right hemispheres operate together to regulate bodily functions and to interpret the world we live in. In brief, schizophrenia is a condition where the left cerebral hemisphere overly dominates the right. Some might be led to believe that schizophrenics interpret reality irrationally, but the opposite is true. Schizophrenics are hyperrational to a fault.

Schizophrenia has been on the rise this past half century or so, but this might just be a symptom of Modernity, as cultures are also experiencing a leftward shift—a shift toward hyperrationality. Cultures have swung like a pendulum from left-hemisphere-dominance to right dominance and back through the ages, but we may be seeing an uncorrected swing further and further to the left, led by science, followed by commerce and politics, dangerously close to the territory of schizophrenia, if not already occupying this territory. Allow me to briefly summarise how the hemisphere function to help the reader understand what it means to be too far left or right.

Cerebral Bilateral Hemispheres

Most people experience the world—what some otherwise known as reality—with both cerebral hemispheres, and each hemisphere has a function. In a nutshell, the right hemisphere experiences reality holistically, which is to say that it views the world through a Gestalt lens. The right hemisphere is open and divergent. It is creative—generative. It knows no categories or subdivisions. All is one and connected. I like to refer to this as Zen. Many people can relate to this Zen notion. The right hemisphere is a creative and empathetic centre that only knows the world as it is presented—without words or naming. Intuition lives here. It distinguishes differences in the world in a manner similar to that of a preverbal child who can tell mum from a bowl of porridge without knowing the word for either. Children are right hemisphere creatures. As we mature toward adulthood, the function of the left hemisphere increases to offset the dominance of the right.

The left hemisphere is the sphere of intellect. Its function is to categorise, to create symbols—words, names, labels, icons, and so on. It doesn’t know how to create, intuit, or empathise. In fact, it doesn’t even experience the world as presented; it relies on re-presentation. To borrow from a computer analogy, when it experiences something in the world, it caches a symbol. Where the right hemisphere experiences a tree and just appreciates its ‘treeness’, and it doesn’t know that it’s a tree by name. It’s just another thing in the world. The left hemisphere, on the other hand, notices these things with ‘treeness’ and categorises them as trees—or des arbres, árboles, Bäume, 木, درختان , पेड़, or whatever. And it reduces the tree to an icon, so it can file it away for later retrieval to compare with other tree-like inputs.

The left hemisphere is where difference, the sense of self, and ego come from

The left hemisphere is where difference, the sense of self, and ego come from. Where the right hemisphere is open and divergent, the left hemisphere is closed and convergent. It is particularly egotistical, stubborn, and always thinks it’s right if I can anthropomorphise analogically. The left hemisphere knows no nuance, and it doesn’t recognise connotation, metaphor, allegory, or allusion. Everything is literal.

The left hemisphere can use similes and understand that a man is like a tiger, but it takes the right hemisphere to know that a man is a tiger, has metaphorically embodied the tiger and assumed its form, say in the manner of indigenous Americans. Poetically, there is a difference between being a tiger and being like a tiger. The left will have none of this. The response to hearing ‘he was a tiger’ would either result in ‘no he isn’t, he’s a human’ or ‘someone must be talking about a male tiger’. The nuance would be lost.

At the risk of further digression, this is why a poem can’t be dissected for meaning—this despite so many valiant attempts by high school teachers and undergraduate professors. Dissecting a living poem is like dissecting a living animal. You might learn something, but at the risk of devitalisation—you’ve killed the subject. It’s like having to explain a joke. If you have to explain it, it didn’t work. You can’t explain a work of art or a piece of music. The best you can do is to describe it. Although we’re likely familiar with the adage, “A picture is worth a thousand words”, a thousand words is not enough to do more than summarise a picture. This sentiment is captured by Oscar Wilde when he wrote, “Education is an admirable thing, but it is well to remember from time to time that nothing that is worth knowing can be taught.” Education is a left-brain function, that can be stuffed like a sausage, but no amount of education can make someone feel a work of art, music, or poetry. This can only be experienced and is apart from language.

A Tree is not a Tree

As already noted, schizophrenics are hyperrational. They are devoid of the empathy and intuition afforded by the right hemisphere. So, they fail to connect the parts to a constructed whole. They presume that a whole is constructed of parts. This is the mistake of Dr Frankenstein, that he could construct a man from parts, but all he could manage is to construct a monster.

In the experienced world, there are only whole objects as experienced by the right hemisphere. As humans, we break them down for easier storage and retrieval, but this is like lossy compression if I can risk losing some in technical lingo.

But a tree is not built from parts. It’s just a tree. We can articulate that a tree has a trunk and roots and branches and leaves and seeds and blooms, but it’s just a tree. The rest we impose on it with artificially constructed symbol language. This is what post-modern painter Rene Magritte was communicating with the “Ceci n’est pas une pipe” inscription in his work The Treachery of Images—This is not a pipe. He was not being cute or edgy or trying to be clever. He was making the point that the symbol is not the object.

In the manner that the image is not the pipe, it’s been said that to document a system is to make an inferior copy. The documented system is less optimal. This may feel counterintuitive. In fact, you may even argue that a documented system allows subsequent process participants to plug into the system to allow it to continue to operate into perpetuity. Whilst this is true, it comes at a cost. I’ll leave this here for you to ponder. The right hemisphere understands the difference. The document is not the process.

Getting Down to Business

If you’ve been following along, you may have already noticed that the left hemisphere looks and sounds a lot like the business world. Everything is systematised, structured, and ordered. We have all sorts of symbols and jargon, processes, and procedures. Everything is literal. There is no room for metaphor. There is no room for empathy. HR instructs that there be empathy, but they might as well instruct everyone to speak Basque or Hopi. In fact, it’s worse because at least Basque and Hopi can be learnt.

Sadly, this leftward shift isn’t limited to the world of commerce. It’s affected science, politics, and entire cultures. It’s caused these entities to abandon all that isn’t rational as irrational. But empathy and intuition are irrational. Science says if you can’t measure it and reproduce it, it’s not worth noting, but science is not the arbiter of the non-scientific realm. Business takes a similar position.

Politics of the Left (Hemisphere)

And politics creates categories: left and right, red and blue, black and white, men and women, gay and straight, and this and that. All of this is all left-hemisphere debate.

Categories and names are exclusive provinces of the left hemisphere. If you are hung up on an ideology, whether Democracy, Republicanism, Marxism, or Anarchism, you’re stuck in your left hemisphere. If you defend your positions with logic and words, you’re stuck in your left hemisphere. If you can’t imagine an alternative, you are really stuck in the left. I’ll stop here.

Science and Scientism

How did we get here and come to this? Science was receptive to right hemisphere influence up until about the 1970s. That’s where Scientism began to take hold. Scientism is when faith in science becomes a religion. I feel that many scientists today are less likely to hold a belief in Scientism as a religious belief. Paradoxically, I think this is more apt to be a faith held by non-scientists. Unfortunately, this faith is exploited by politics as exemplified by the recent trust in science campaign perpetrated by politicians, which is to say non-scientists with their own agenda, whether they practised Scientism or not.

The problem is that the left hemisphere has an outsized ego. It thinks it’s always right. In practice, it’s right about half the time. Because of its reliance on stored data and a ‘belief’ that it doesn’t need to fresh its data until it’s effectively overwhelmed and acquiesced. It fails to give enough weight to the experienced world, so that it shifts belief further and further left, which is to say further from reality as it is.

It trusts the symbol of the tree more than the tree itself. We may all be familiar with stories of cars driving down train tracks and off cliffs because the SAT-NAV user put more faith in their device than the world outside. This is the risk companies face as well, choosing to believe that the documented process is superior to the system in and of itself.

Getting on About?

You may be wondering what inspired me to write this and where I get my information. My realisation started in chapter 9 of The Matter with Things and was reinforced by this video interview by its author, Iain McGilchrist.

Actually, it started even before this with The Corporation, a Canadian documentary and companion book released in 2003. One of the points of The Corporation is to articulate the parallels between corporate behaviour relative to the definition of psychopathy as presented in The Diagnostic and Statistical Manual of Mental Disorders, henceforth DSM. Per Wikipedia, the DSM ‘is a publication by the American Psychiatric Association for the classification of mental disorders using a common language and standard criteria and is the main book for the diagnosis and treatment of mental disorders in the United States and is considered one of the “Bibles” of psychiatry’. Essentially, corporations ticked all the boxes.

Methodologically, this assertion is a bit weak, but it is at least sometimes entirely valid despite provoking an emotional trigger reaction. Nonetheless, this established corporations as pathological entities. But that is not my focus here. It simply tilled the soil for me to be more receptive to this topic. This topic is less about the legal fiction that is a corporation and more about the people embodied in it. From the height of the C-suite to the workaday staff, floor workers, warehouse workers, and the mailroom. Do they still have mailrooms? I digress.

I can’t claim to know what it is to be schizophrenic or schizoaffective, but I’ve known enough people who have these diagnoses. My brother was one of those. Although I use these and other labels, I am not a fan of labels, generally, especially psychological labels, specifically this label. Autism is another nonsensical label. Both fall into the realm of medical syndromes, which for the uninitiated is the equivalent of your kitchen junk drawer. It’s equivalent to the other choice when all others fail. I don’t want to go off on a tangent from the start, so I’ll leave it that these categories are overly broad and reflect intellectual laziness. There is no single schizophrenia or autism. There are many, but the distinction is lost in the category. The push to create an autism spectrum for DSM obscures the problem, but it helps for insurance purposes. As the saying goes, follow the money and you can gain clues to the driving force behind why this happened. I suppose you can also label me a conspiracy theorist. If I learned one thing in my undergrad Sociology classes, it’s to eschew labels.

Almost finished

Given the length of this segment, I am not going to summarise it here, save to say that this leftward shift in business and culture doesn’t have a good outlook. We are not only being replaced by machines, but we are also forced into becoming machines, and we aren’t even questioning it. All we need to do is to become more analytic, right?

What I suggest is to watch the six-minute video of Dr Iain McGilchrist discussing this topic, and if you really want a deep dive, read The Matter with Things, an almost three-thousand-page tome, to fill in the details.

Postscript

Here’s a music analogy to help to express why the whole is more important than the sum of the parts. If I want to learn to play a new piece, I will listen to the piece first. Depending on the length and genre, I may have to listen many times. In some cases, once or twice is enough, but let’s say this is at least somewhat complex and not some repetitive three-chord pop song. I’ll probably break the song into pieces or movements—verse, chorus, bridge, and whatever—, and then, I’ll learn each note and each pattern of notes, perhaps as musical phrases. Once I figure out the verse, I might either learn how the next verse differs or move on to the chorus and defer that verse-to-verse step. I’ll rinse and repeat until I’ve got through each of the sections. If I’ve had the luxury of hearing the piece, I’m at an advantage as far as tone, timbre, and dynamics are concerned; otherwise, I’d better hope these are all documented and that I interpret them in the manner they were intended. If the audience is familiar with a tune, they’ll notice the difference.

When I am practising, I need to get the mechanics down pat. All of what I’ve described thus far is left-hemisphere fare. It’s translating the symbolic representation of notes—like letters and words in writing—into an utterance. In this case, it’s a musical utterance. But once I am ready to perform the piece, it needs to be performed through the right hemisphere or it will feel mechanical and stilted.

I used to earn my living as an audio recording engineer and producer. Most of the time I was working with unknown artists recording demo records and trying to get a record deal. For the uninitiated, that usually translated into not having a large recording budget. Occasionally, we want, say string parts—violins, viola, cello, or whatever—but we couldn’t afford union players. We’d hire music students from USC or UCLA. These players would be more than willing to play for cheap in exchange for something to add to their portfolios or experience chops.

Somebody would transcribe the musical notation, and we’d give it to the string player. Of course, it could be a keyboard or wind or reed part, but I’ll stick to strings. Part of music is the vibe. This is something that can’t be captured in symbols. Revisiting Scientism and the left-hemisphere analogy, vibes can’t be real because they can’t be notated.

Almost invariably, if we got someone with Classical training, they could not get the vibe. The music was right in front of them. We’d play it for them on piano, maybe on a synthesiser, but they couldn’t get it—even if they were playing along to a reference track just trying to double the synth part. They would hit every note for the specified duration and dynamic, but it might have as well been the equivalence of a player piano or music box.  We could have played it on a synthesiser, but we might be seeking the nuance a real instrument would bring.

We never had the luxury of auditioning players or recording several players and grabbing the best parts. That’s for the bigger-budget artists who go through a half-dozen or more performers to get just the right one. When we got lucky, it was usually because we got someone from the jazz program. These cats seem to have a natural feel for vibe inaccessible to the classical performers.

In business, the classical performer is good enough, but for art, it wasn’t. Business might appreciate the difference if it happens to get it, but it won’t seek it, and it won’t pay for it. A pet peeve of mine is a quip in business I heard often—don’t let perfection be the enemy of the good. This is obviously a left-hemisphere sentiment based on Voltaire’s statement. Besides, even from a left hemisphere perspective, reciting, “Don’t let perfection be the enemy of the good” doesn’t mean you shouldn’t at least strive for good enough because I noticed that mark was missed often enough, too.

The Matter with Things: Chapter Nine Summary: Schizophreia &c.

Podcast audio version to follow.

Intro

Creativity is chapter nine of Iain McGilchrist’s The Matter with Things. It also marks the end of part one of three in this two-volume set.

The main thrust is to provide a lot of cases of schizophrenia to elaborate on how the deficits impact perception—and of course, attention and judgment.

Content

This chapter starts off by noting that mental illnesses are not a matter of the brain being broken like a machine. McGilchrist doesn’t much like the analogies to machines or computers, to begin with. Instead, they affect how their world is experienced. They attend to different things, which creates a different perception because we perceive what we attend to.

It is effectively a left-hemisphere challenge, but he is careful to say that we don’t have enough evidence to call it a right-hemisphere deficit. His rationale is that it could be one of these three leading scenarios:

  1. The right hemisphere has deficits.
  2. The left hemisphere is not performing its function to work with the right hemisphere, which is otherwise intact.
  3. The frontal lobe which is supposed to moderate the hemispheres is not performing its function.

Schizophrenia and autism are distinct conditions, but there are some overlaps. He clarifies that schizophrenia and autism are too broad of categories (a situation made worse in the case of autism by the creation of the autism spectrum). There are types of schizophrenias and autisms that would otherwise be unrelated except for psychology’s kitchen junk drawer approach to categorisation, I suppose, following the lead of syndromes in the medical profession. I digress.

These conditions exemplify what it’s like to experience the world with an overreliance on the left hemisphere. A point he wants to make is that he feels society at large is shifting in this direction to the detriment of all concerned, that the world of business, science, politics, and bureaucracy more generally is migrating to a hyper-rational position at the expense of experiential reality.

He praises Louis Sass’s 1992 book Madness and Modernism as “one of the most fascinating, and compelling, books I have ever read”, primarily because it notes the relationship between schizophrenia and Modernism and a modern world that is experiencing an increase in the phenomena of schizophrenia.

they miss the forest for the woods

McGilchrist goes into detail about how right hemisphere deficits affect perception in schizophrenic patients. I won’t share that level of detail here. Effectively, they miss the forest for the woods and make contextual miscues, lacking in empathy and intuition. Missing this context, they jump to conclusions—invalid conclusions. He goes on to explain this from the perspective of brain construction and physiology whilst extending the conversation to include the autism spectrum, noting a general overlap between these diagnoses.

He invokes the work of Eugène Minkowski—reflecting on the foundational work of Henri Bergson—, which resonated with me, wherein Minkowski tries to simplify and characterise the hemisphere as the left representing intellect and the right being intuition. This feels about right. He shares a list of terms generally representing qualities in schizophrenics that detail what is atrophied in the intuition of the right hemisphere and what is hypertrophied (or exaggerated) in the left hemisphere. I’ll not share this list here, but I like it. He promises to elaborate on this in chapter 22.

Essentially what’s missing is a sense of coherence with experience leading to a detachment from reality as we normally experience it—and a loss of vitality and a sense of self. These people live as outsiders looking in rather than simply feeling a part of the whole. Man becomes a machine built of parts and separate to nature. Everything becomes literal. There is no room for connotation in a denotative world. But this world is disconnected from the presented reality, instead relying on a re-presented version. The world loses depth and becomes a two-dimensional caricature.

Perspective

My summary of this chapter left many details unsaid, probably more so than the preceding chapters, so a lot of context and nuance is missing. My biggest takeaway is really the scary connexion between schizophrenia and Modernity. It is far from comforting. Add to this the positive feedback loop otherwise known as a vicious cycle as societies more and more adopt a left hemisphere perspective, that of a schizophrenic, and it becomes scarier still. To make matters worse, this is not metaphorical. It’s analogical. I’m not sure how to reverse this tide.

connexion between schizophrenia and Modernity

This wraps up the chapter on schizophrenia, autism and the rest. As I mentioned at the start, this also marks the end of part one of the book. The next chapter is “What is Truth?” This will allow the reader to delve more deeply into various aspects of truth, from science to reason to intuition and imagination. This second part of the books takes us to the end of the first volume, traversing us through chapters ten to nineteen.

What are your thoughts on mental illnesses like schizophrenia and autism, especially around how they may shed light on neurotypical persons and the relationship between these and modern society?

The Matter with Things: Part 1 Chapter Orientation

Posted in intelligence, perception, philosophyTagged , , , , , , Leave a comment

I can’t recommend Iain McGilchrist’s book, The Matter with Things, highly enough. I recommend reading The Master and His Emissary first. I didn’t figure this out until I started reading The Matter with Things, so I am reading them in parallel.

The book arrives as two volumes split into three sections. Part one is the foundation the rest of the book builds on. I’ve recently finished it and summarised each chapter, but I feel a high-level chapter orientation would be in order. Part one contains nine chapters:

  1. Some preliminaries: how we got here
  2. Attention
  3. Perception
  4. Judgment
  5. Apprehension
  6. Emotional and social intelligence
  7. Cognitive intelligence
  8. Creativity
  9. What schizophrenia and autism can tell us

Here’s the breakdown:

Some preliminaries: How we got here

As this book is a follow-up to The Master and His Emissary, published in 2008, Iain has already laid much of the foundation for it. Moreover, he doesn’t assume that you’ve already read The Master and His Emissary, and the work leading up to it, so this is what he outlines here as he drops hints of what’s to come in the chapters ahead.

Attention

This chapter reminds us that we cannot perceive what we don’t attend to, to pay attention to. The world outside just is, and we can attend to this or to that. From there, our perception will develop, perhaps, in turn, drawing out attention elsewhere.

As is a thread throughout, Iain uses various mental illnesses and split cerebral hemispheres to make his points. In this case, he tells us how neuro-atypical people have attention challenges, whether attending to the ‘wrong’ or otherwise inappropriate things or attending to too many things at once, flittering from this to that to the next thing without pause or resolution.

Perception

This chapter articulates how we perceive after attention has been focused. Perception is based on prior experience and knowledge combines with new sensory inputs.

Following the trend of people with hemisphere disturbances, Iain reminds us that people coming from different experiential places will perceive the same scenario differently. And if they are attending to the ‘wrong’ stimulus, their perception may be limited to that context, even if that micro-focused scope is otherwise correct.

Judgment

For some reason, Iain uses the American English spelling of Judgment, which in this case happens to be my preferred rendition, though my spell-checker disagrees.

In this chapter, we move from attention and perception to now being able to make judgements in this space. Of course, if we’ve attended to the ‘wrong’ thing leading to a variant perception, our judgment may be similarly out of order. Following the American trend, let’s say I am watching a baseball match, and the umpire calls a ball thrown out of the strike zone as a strike. If instead, my attention was distracted to another person in the stands picking his nose, my perception of the strike situation would be peripheral at best, and I would be in no place to make a judgment—about the pitch in any case. I may likely have plenty of judgment about the nose-picker.

In a nutshell, judgment is a left hemisphere function. The right hemisphere simply doesn’t care to judge. It’s a dispassionate observer taking in all without even categorising, let alone judging.

Apprehension

In this chapter, Iain explains that he is employing the term apprehension classically to mean to grasp or hold onto. This is a left hemisphere function as well. The right hemisphere is not grasping. Deficits in the right hemisphere don’t allow one to view the world in context as a whole. The left hemisphere will just see things are disconnected parts, so whilst we might grasp and apprehend, our comprehension is deficient. Without a robust big picture, we may just grasp at things indiscriminately.

Emotional and social intelligence

This chapter and the next are about intelligences. As the name suggests, this chapter is concerned with emotional and social intelligence. For me, I think of the Raymond character in Rain Man, itself the result of a misperception of the name Raymond for the phrase ‘Rain Man”. Raymond is devoid of emotional and social intelligence. He is limited to mechanistic cognitive intelligence and is a fine example of what one looks like without the other.

This chapter reminds us that the right hemisphere not only constructs our sense of self, but it also facilitates the construction of other selves, which allows us to empathise with others. It also allows us to assess intent. It allows us to see the value of the whole of society. Of which we are parts rather than thinking that we are simply parts that make up the whole. This is an important distinction. This is what happens with the ego of the left hemisphere denies the Gestalt of the right.

Cognitive intelligence

This second chapter on intelligence focuses on the cognitive variety. It’s what we think of when we consider IQ scores and such. It’s the reasoning part of the brain. It’s about rote learning and reciting trivia and perceived facts as re-presented by the left hemisphere.

Creativity

In this chapter on creativity, we are told that this is a right hemisphere function. To be creative, the best advice to keep the left hemisphere from engaging and interrupting. Creativity comes to us holistically. It is not the result of a process. It is an absence of process. Thinking and analysis are the antitheses of creativity. This is a case where less definitely is more.

What schizophrenia and autism can tell us

Each of the chapters touches on aspects of schizophrenia and other mental illnesses and situations where the hemispheres get disconnected or out of whack. In this chapter, Iain drives the point home with a focus on these cases and what it can tell us about these neuro-atypical conditions.  

People assume that schizophrenics and autism spectrum people are irrational, but this is precisely incorrect. In fact, it’s the opposite. These people are hyper-rational at the expense of empathy and social intelligence. It’s not a surprise that we are seeing more schizophrenics these days. Neither is it a surprise that we see a modern society that more and more resembles schizophrenia. But I digress.

Summary

This was only meant to give a high-level vantage to connect the chapters of part one of The Matter with Things. I give more comprehensive summaries on my blog. This will give you more of an idea, but my recommendation is to read the book itself as well as The Master and His Emissary which I recommend reading first. Don’t be like me. 

Seeing the World As It Is

Posted in art, perception, philosophy, videoTagged , , , , , Leave a comment

Cubism reminds us that we don’t see the world as it is. We see pieces, and we fill in the gaps. From the front, we can’t see the back. From the top, we can’t see the bottom.

Video: YouTube Video


The illusion that, if we can see something clearly, we see it as it really is, is hugely seductive.
John Ruskin makes the point that clarity is bought at the price of limitation. He paints a scenario wherein we are asked to imagine viewing an open book and an embroidered handkerchief on a lawn. From a quarter mile away, the two are indistinguishable. Moving closer, we can see which is which, but we can neither read the book nor trace the embroidery. Closer still, we can read the text and trace the embroidery, but we can’t see the fibres of the paper or the threads of the kerchief. And we can’t simultaneously focus on both and see detail in each. Focusing on the book, we can look closer and see the watermark, the hills and dales in the paper’s surface. With a microscope, we can see more still, as infinitum.

But at which point do we see it clearly?

I’ve created a YouTube short. I have to admit that I dislike the format. Sixty seconds isn’t really enough time to convey a concept. There’s too much missing context, and no time to elaborate. Nonetheless, I was reading The Master and His Emissary and wanted to share a point. I don’t feel I succeeded. I posted it anyway, and here it is.

To Be or Not to Be (Free)

Posted in agency, consciousness, free will, perception, philosophy, psychology, videoTagged , , , , , Leave a comment

I recently posted a YouTube Short video titled You Have No Free Will, but this is still debatable.

Video: You Have No Free Will

The premise of the belief in free-will is that human decisions are made approximately half a second before we are conscious of them, and then the conscious brain convinces itself that it just made a choice. This sounds pretty damning, but let’s step back for a moment.

Podcast: Audio rendition of this page content

If you’ve been following this blog these past few months, you’ll be aware that I feel the question of free will is a pseudo-question hinging primarily on semantics. As well, there’s the causa sui argument that I’d like to ignore for the purpose of this post.

There remains a semantic issue. The free will argument is centred around the notion that a person or agent has control or agency over their choices. This means that how we define the agent matters.

In the study this references, the authors define the agent as having conscious awareness. Since this occurs after the decision is made, then the person must have had no agency. But I think an argument can be made that the earlier decision gateway is formed through prior experience. Applying computer metaphors, we can say that this pre-consciousness is like embedded hardware or read-only logic. It’s like autopilot.

In business, there are various decision management schemes. In particular, the conscious but slow version is for a person to be notified to approve or deny a request. But some decisions are automatic. If a purchase is over, say 50,000 then a manager needs to sign off on the request. But if the purchase is under 50,000, then the request is made automatically and then the manager is notified for later review if so desired.

I am not saying that I buy into this definition, but I think the argument could be made.

You might not know it by the number of posts discussing it, but I am not really concerned about whether or not free will really exists. I don’t lose any sleep over it. At the same time, I tend to react to it. Since I feel it’s a pseudo-problem where tweaking the definition slightly can flip the answer on its head, it’s just not worth the effort. On to better things.

The Matter with Things: Chapter Six Summary: Emotional and Social Intelligence

Posted in language, perception, philosophy, podcast, psychology, scienceTagged , , , , , , , 4 Comments

Index and table of contents

Intro

Chapter 6 of The Matter with Things is titled Emotional and Social Intelligence, following the previous chapters, Attention, Perception, Judgment, and Apprehension. Chapter 7 is about cognitive intelligence.

The gist of chapter 6 is to convey the importance of emotional and social intelligence in forming a full picture of the world. Absent these, reality becomes increasingly tenuous to retain a grip on because the left hemisphere just doesn’t have the emotional awareness to grasp the full picture. 

Audio: Podcast version of this page content

Content

At the start, this chapter reminds us that the right hemisphere not only constructs our sense of self, but it also facilitates the construction of other selves, which allows us to empathise with others. It also allows us to assess intent. And it goes deeper than this.

McGilchrist shares some anecdotes about schizophrenic patients with impaired right hemispheres who believe that nothing is real and that people are play-acting. In hospital, they perceive the ward to be a stage and the medical staff to be actors.

As if by a control knob, changes to the right hemisphere may create a diminished sense of reality as well as an intensified sense—of being hyperaware. This is not dissimilar to certain claims by some with heightened lucidity; however, the data do not permit a clear-cut conclusion. On a related note, the intensified sense may also increase emotional reactions, so one might be more prone to crying—whether tears of joy or sadness.  

Abnormal electrical activity in the right hemisphere can heighten a sense of familiarity leading to a sense of déjà vu. A diminished sense has the contrary effect, reducing a sense of familiarity, leading to a sense of jamais vu, ‘never before seen’, Related to déjà vu, there have been cases of déjà vécu, ‘already experienced’ (rather than seen). Together, over 86% of these phenomena are associated with the right hemisphere.

Recall that each hemisphere controls the body contralaterally, so the right hemisphere controls the left side of the body—hands and arms, eyes, and so on. And it’s deeper than this. For example, being the arbiter of empathy, the left hand (being controlled by the right hemisphere) is used for empathetic touch. Beyond humans, bottleneck dolphins tend to stroke other dolphins with their left flippers.

This affects humans and other animals with a sort of left-eye empathy that even affects how babies are held or otherwise attended to, preferring the left side of the body over the right.

Theory of mind (ToM), a topic in its own right, is a right hemisphere-dominant capability that allows us to empathise with another or to put ourselves into another’s shoes. This ability extends to other species like elephants, apes and dogs, whales and dolphins, crows and magpies, and goats and seals.

The left hemisphere is good at understanding the what of actions

The left hemisphere is good at understanding the what of actions, say picking up a cup or flicking a switch; it’s not so great at discerning the why. Recall in a previous chapter the case of the person with right hemisphere damage automatically picking up a pen or pencil but then not having anything particular in mind to write. The left hemisphere noticed the pen as a writing instrument and picked it up. Without the right hemisphere to provide the why, this person just kept accumulating writing implements.

This can be seen in children with autism. They recognise well enough that a person is doing something—performing some action—, but they just can’t understand why.

He tells us that “a huge body of evidence confirms that the right hemisphere is much superior to the left in receiving, interpreting, recalling or understanding anything that involves emotion.”

I’ll just share one example, and McGilchrist provides common responses from persons with both hemispheres intact as well as responses with right hemisphere deficits. For image b, a ‘normal’ response is for the respondent to fill in the boy’s talk bubble with ‘Boy, she’s cute.’ A couple of right hemisphere deficit responses were ‘I wonder how big her allowance is’ and ‘Let’s arm-wrestle’, obviously missing context.

The right hemisphere is responsible for understanding emotion, irony, jokes and humour—and the ability to tell the difference between jokes and lies. When told a joke and given an opportunity to fill in the punchline, the language of right hemisphere deficit patients ‘is often excessive and rambling; their comments are often off-colour and their humour is frequently inappropriate; they tend to focus on insignificant details or make tangential remarks’. Moreover, when asked to reconvey a story, the right hemisphere deficit people produced an ‘abundance of embellishments’ to it.

One subject with right hemisphere resection asked, ‘how do you feel?’ responded ‘With my hands’

Other right hemisphere functions are the ability to grasp the semantic nuance and intonation of a speaker. One subject with right hemisphere resection asked, ‘How do you feel?’ He responded, ‘With my hands,’ but he wasn’t joking.

People who have undergone a right hemispherectomy demonstrate a ‘shallow affect, rigidity, [and] lack of imagination’. The left hemisphere seems to prefer denotative speech whilst the right prefers connotative, hence a broader set of possible meanings. Interestingly, yet perhaps not surprisingly, clichés are the domain of the left hemisphere. Poetry and music reside on the right.

Wrapping up this chapter, the right hemisphere tends to serve as the emotional centre, save for anger, which is a left hemisphere activity.

Perspective

In summary, the left brain is very focused. Damage to the right hemisphere mimics the responses of autistic and schizophrenic individuals who interpret inputs differently and without nuance. This nuance often contains emotional or empathetic content that is lost on this cohort.

I am left wondering if schizophrenia and autism are right hemisphere problems, as it were, or if I would be reading into things to arrive at this conclusion.  

Having completed Emotional and Social Intelligence next up is a chapter on Cognitive Intelligence. I hope you’ll join me.

What are your thoughts? What did you think of this chapter? Were there any surprises? Anything of particular interest?

Cerebral Hemisphere Differences: Woods and Trees

Iain McGilchrist feels that the world is moving too much toward a left hemisphere-dominated world. This has happened before, ebbing and flowing, and perhaps it will change direction again at some point. Although this compartmentalised thinking has its roots at the beginning of the Age of Enlightenment, it has accelerated in the past century as specialisation has too many of us losing the woods for the trees.

Humans have “a sufficiently strong propensity not only to make divisions in knowledge where there are none in nature, and then to impose the divisions on nature, making the reality thus conformable to the idea, but to go further, and to convert the generalisations made from observation into positive entities, permitting for the future these artificial creations to tyrannise over the understanding.”

— Henry Maudsley, The Physiology and Pathology of the Mind,1867

I hope McGilchrist explores extreme right hemisphere dominance more in The Master and His Emissary, whether relatively due to a deficient left hemisphere or because of the right hemisphere running amok.

McGilchrist warns the reader time and again that both hemispheres are involved in many activities, and it is what they are doing or how they are processing the events that differ. But when we generalise some primary competencies—a decidedly left hemisphere activity—, we notice that the left hemisphere is about constrained thinking with a focus on elements rather than the whole as illustrated previously and creating a map to re-present those data.

A Woman’s Face in the Trees: Gestalt in Action

Conversely, the right hemisphere is about openness and experiencing the world as it is presented rather than a re-presentation. I likened this to a Zen approach. It would probably not be unfair to relate this to the Buddhist notion of oneness and selflessness.

Given Iain’s assessment, perhaps right hemisphere dominance is not our biggest concern at the moment. However, I perceive a potential problem. Given the right hemisphere’s proclivity toward Gestalt, I am concerned that it also overgeneralises things into a whole where they shouldn’t be connected, as such. Gestalt is what fills in spaces in perception to make it appear as a whole. I’ll consider this to be an interpolation. But if it interpolates wrong, we may incur fitness penalties. Aside from this, I consider extrapolation—or perhaps misidentified boundary states, which is to say we include aspects outside of the ‘real’ domain boundary and glom it onto the model because, cognitively speaking, we don’t know what to do with it or how to interpret it. Once it gets passed to the left hemisphere, it (incorrectly) codifies it, from that point onward being mis-re-presented.

So where the left hemisphere loses the woods for the trees, the right hemisphere annexes the neighbours’ woods.

Cerebral Hemisphere Differences: Pattern Definition

Continuing with a quick post based on observations in The Master and the Emissary by Iain McGilchrist, another example of hemispheral specialisation is illustrated in the image below.

A typical person will envisage this large S composited with smaller Ss (that could be replaced with any symbols, so there is nothing special about the S comprised of Ss) as represented by the centre image of the rendition of the bilateral interpretations.

Where there is left hemisphere damage, the right would envisage something more like the S on the right—seeing the big picture but losing detail. Where there is right hemisphere damage, the left would perceive something more like the S on the left, which is the detail of the composite Ss without recognising that they composed a bigger picture. This is conveyed in the aphorism of losing the woods for the trees whilst the former right hemisphere dominant view might not realise that the forest has trees.

But even this misses the point slightly because if you are viewing this as a typical person, you can assemble the Ss on the left and realise that it makes a larger S whereas a person with right hemisphere damage will just see a mass of Ss and not see the larger S shape. Moreover, it’s not that the right hemisphere wouldn’t ‘see’ the smaller composite Ss, it just wouldn’t put any significance on them, thus ignoring them and considering them to be background noise.

I really do want to share about the non-stereoscopic animals as well as another instalment from The Matter with Things. At least one of these is probable for the next post.

Cerebral Hemisphere Differences: The Colour and the Shape

One key aspect of left and right hemisphere differences is the notion of identification versus naming and categorisation. I tend to view the right hemisphere as rather Zen. It just sees things as they are without particular care, judgment, or attachment.

2 Orange Circles as tentatively experienced by the left and right hemispheres of the brain.

I composited a quick illustration to convey the difference. Starting with the right hemisphere, the object is recognised in a global context. Whilst it can be distinguished from a blue thing or a square thing, this is done by holistically surveying the world. The difference is perceived but rather without reflection on memory.

Generally speaking, both hemispheres ‘see’ the object, but where the right hemisphere is interested in the object as presented, the left hemisphere is interested in re-presentation. Where the right hemisphere is about being open to the experience itself, the left closes.

From an evolutionary vantage, the right hemisphere is interested in surveying the world at large and being alert to potential danger or survival queues, perhaps a food source. If the right hemisphere is triggered, the left hemisphere jumps in. This said, the left hemisphere is tightly focused, so if something does alert it—remembering that it is not switched off awaiting the right brain to activate it—, it will respond more quickly than the right hemisphere, though as I’ve noted previously, accuracy is not it’s forte, as the right hemisphere may have to convey that the snake that startled you was, in fact, a garden hose.

The left hemisphere is where categorisation and naming take place. Moreover, it stores the object for later retrieval, creating a map. If a subsequent observation is made, it is compared and contrasted relative to the map. After enough observations are made, the left brain isn’t so interested in observing the external world. It perceives a circle-y shape or perhaps an orangy colour and is convinced (metaphorically) that its cached version is satisfactory.

There is a book named Drawing from the Right Side of the Brain. I don’t want to comment on the book in depth, save to say that the author’s premise is that the so-called left-hemisphere person will look at the face of a subject and draw a generic oval shape. The eyes will be general eye shapes, following the same pattern for the nose and mouth. In the end, they will have rendered a portrait on the level of a child.

Whistler’s Mother, a restoration as reimagined by Mr Bean in the movie Bean.

The artist who inhabits the left brain will instead note the contours, shadows, and colours of the face in front of them. One exercise that I had learned in some art class years before I read this was to draw from an inverted portrait. Not being so common as upright faces, the left brain has no representations modelled and so defers to the right hemisphere that is now looking at the object—the terrain—rather than the model.

I find the divided hemisphere activity in animals without stereoscopic vision to be fascinating. Perhaps, I’ll comment on this next.

* I am not claiming that the right hemisphere sees the world as fuzzy or hazy. Rather, this was me taking artistic licence to not ascribe strict boundaries to the objects in the world, especially as constrained by language.

Half-Life of Facts

Posted in language, perception, philosophyTagged , , , , , , , 2 Comments

A colleague shared this article, which asks, “Should we really believe scientific facts will last forever when history is full of revolutions in thinking?” I discuss this in a recent post, The Truth about Truth.

The only thing I’ll add is the separate notion of the half-life of knowledge—essentially what we treat as fact will in fact (pun intended) not be true for one or another reason. This article gives the same case I mention, which is the invalid notion of a geocentric world. In some cases, it was true in a particular context, but the context is no longer valid. In other cases, the revision has been one of increased precision or accuracy, perhaps Newtonian versus Einsteinian physics.

Even in the case of tautological facts, things can change and meanings can shift. In the case of the colour spectrum, Newton wanted to mimic the Western musical notion of the octave, so he assigned colour names to the light spectrum when viewed through a prism, but there are two differences between his proclamation and our current understanding.

For one, what he labelled blue, we’d today call cyan. Sure, it’s in the family of blues, but when we think ‘blue’, we aren’t likely imagining cyan.

Moreover, he injected indigo to arrive at the seventh colour note, per the octave. But this was just a shoddy addition made in haste. In fact (there I go again), indigo would likely be named dark blue today.
