Machine learning used to successfully predict psychosis

A very interesting study shows that a computer analysis of language use has predicted early signs of future psychosis with ~90% accuracy in at-risk individuals.

,,,results revealed that conversion to psychosis is signaled by low semantic density and talk about voices and sounds. When combined, these two variables were able to predict the conversion with 93% accuracy in the training and 90% accuracy in the holdout datasets. The results point to a larger project in which automated analyses of language are used to forecast a broad range of mental disorders well in advance of their emergence.  (A machine learning approach to predicting psychosis using semantic density and latent content analysis)

An article about the study says:

The results showed that higher than normal usage of words related to sound, combined with a higher rate of using words with similar meaning, meant that psychosis was likely on the horizon. (The whisper of schizophrenia: Machine learning finds ‘sound’ words predict psychosis)

Phillip Wolff, an author of the study, says of it:

“This research is interesting not just for its potential to reveal more about mental illness, but for understanding how the mind works — how it puts ideas together. Machine learning technology is advancing so rapidly that it’s giving us tools to data mine the human mind.” (Ibid)

Ambiguity in speech as the source of most psychology

Genes aside, I believe ambiguity in speech and its consequent cascades of error are at the root of virtually all human psychology, both good and bad.

And this goes back in time as far as we can imagine because the problem of ambiguity in speech was there for your parents, your grandparents, and everyone else who came before you. And the same is true for everyone else in the world.

All cultures everywhere are both burdened and determined by this problem.

(The only exceptions are specialist “cultures” that make a point of removing error from their communication systems, such as mathematics, hard sciences, engineering, some branches of linguistics, etc. The people in these cultures only avoid the problem while working or speaking within their specialist culture. When at home or off the job, their psychologies are the same as the rest of us. In fact, smart as many of those people are, I bet few of them have ever considered how inaccurate their common speech is or how error-ridden their listening is, to say nothing of how profoundly that messes up their psychologies.)

Ambiguity in speech comes from inaccurate words and phrases, our strong tendencies to want to keep the wrong parts of speaking too short, our fear of open, truthful speech, our hyper-focus on wording and typical refusal to allow people to take back or alter their words or our inability to see the need for that, our strong tendency to believe we know what others mean, our constant need to grab meaning on the fly, or extract it from gestures or tone of voice, the brevity of most speech acts, our fear of being wrong or saying the wrong thing (legitimate fears given the foregoing), our practical incapacity to describe our own subjectivity or even know it, our inability to get other people’s subjectivity from them because they also suck at this.

I could go on, but let’s just take one item from this loose list—our typical refusal to allow people to take back or alter their words or our inability to see the need for that.

Of course other people do this to us too. And when they do, we rarely know how to deal with it. Even when we try, it often turns out badly because our attempts are stereotypically taken as excuses or apologies.  Moreover, taking something back usually only involves glaring stuff that someone might have felt was “offensive” or that we believe reflects badly on us.

Even worse, let’s say you have taken something back successfully or rephrased it and explained everything perfectly to all parties’ satisfaction. When was the last time you did it? How often do you do it?

Not much, I bet. Because if you do do it often, almost everyone will think you have a loose screw.

How often should you rephrase something you said or allow another to do that?

The right answer is at least several times per hour of conversation.

When we don’t do that, ambiguity flourishes. Meanings are imagined. Guesswork replaces knowing. In response, everyone’s psychologies become confused or rigid. We act roles rather than life.

How can we claim to know anything about human psychology without acknowledging that almost anything with psychological import that anyone ever says to anyone is sure to be riddled with error and ambiguity?

And even when it’s not, 1) it’s very hard to know when that is and 2) the event is so rare it’s like a bird that stops flapping its wings and falls to the ground.

 

Covert speech proscriptions and the psychological harm they cause

Our need to stimulate the brain stem by pushing through difficulties or challenging our senses

…Here’s the crucial part: This expectation is likely to extend the effects of stress-induced pain relief beyond immediate cold exposure. If such an expectation – “I confronted the cold and feel invigorated” – is fulfilled, it will lead to the release of additional opioids or cannabinoids from the periaqueductal gray. This release can affect the levels of neurotransmitters such as serotonin and dopamine, further enhancing a feeling of overall well-being. This positive feedback loop is implicated in the well-known “placebo effect.”

More generally, techniques such as those Hof uses appear to exert positive effects on the body’s innate immune response as well. We expect them to also have positive effects on mood and anxiety because of the release of opioids and cannabinoids. Though these effects have not yet been well studied, by evoking a stress-induced analgesia reaction, we think that practitioners may assert “control” over key components of brain systems related to mood and anxiety.

At present, millions of people use drugs to help with feelings of depression and anxiety. Many of these drugs carry unwelcome side effects. Behavioral modification techniques that train users in ways to influence their brain’s homeostatic system could someday provide some patients with drug-free alternatives. Efforts to understand links between the brain’s physiology and its psychology may indeed hold the promise for a happier life. (Cold comfort: exposure to chilly temperatures may help fight anxiety)

This article describes a very interesting finding that seems to explain why some people like intense sports such as rock climbing, motorcycling, free diving, skiing, and so on.

It also seems to explain why toughing it out is often the best medicine for what ails us or the best method for moving forward with our lives.

Intense religious practices, chanting, long meditations, silence retreats also seem to be drawing on stimulating the periaqueductal gray area of the brain stem.

To some extent, FIML practice does something like this by stopping conditioned and instinctual responses as soon after they have arisen as possible. Doing this requires a mental toughness and perceptual acuity that frequently carries over to other activities.

Working memory improved with electrical stimulation, study shows

Scientists have used a noninvasive form of electrostimulation to boost working memory in older people, effectively giving 70-year-olds the thinking abilities of their 20-year-old selves, at least temporarily. (Scientists Fixed People’s Working Memory With Simple Electrical ‘Zaps’ to The Brain)

The study (paywall) is here: Working memory revived in older adults by synchronizing rhythmic brain circuits.

From the abstract:

…After 25 min of stimulation, frequency-tuned to individual brain network dynamics, we observed a preferential increase in neural synchronization patterns and the return of sender–receiver relationships of information flow within and between frontotemporal regions. The end result was rapid improvement in working-memory performance that outlasted a 50 min post-stimulation period.

This study further demonstrates the importance of electrical waves in brain functioning. It targets working memory decline in older adults but similar improvements were found in young adults already experiencing memory deficits.

“We showed that the poor performers who were much younger, in their 20s, could also benefit from the same exact kind of stimulation,” Reinhart says in a statement.

“We could boost their working memory even though they weren’t in their 60s or 70s.” (Scientists Fixed People’s Working Memory With Simple Electrical ‘Zaps’ to The Brain)

News stories on working memory tend to trivialize it as merely a brain function that helps us remember phone numbers or where we put stuff. When in fact…

…working memory is the part of you that organizes and executes action in real-time. All real-time actions—save stupor or deep sleep—require working memory.

Working memory is where your life meets the world, where your existential rubber meets the real-time road.

Working memory is the spear point of the mind as it does life. For this reason, it is the single best key to understanding human psychology. And through this understanding to change it for the better. (Working memory is key to deep psychological transformation)

Incidentally, Buddhist mindfulness practice can greatly enhance working memory while also adding a metacognitive component to it in circumstances that would not otherwise normally call on metacognition.

FIML practice does something similar in that it adds a layer of psychological and linguistic mindfulness to working memory during acts of interpersonal communication.

Abstract reasoning and mental illness

Speech and emotion

Good speech can and sometimes should be emotional.

Adrenaline, cortisol, and other hormones can and should stimulate our bodies and brains when we discuss subjects that matter.

I love it when my SO stands up to emphasize her words with gestures. Her voice rises with the conviction that her point is relevant and important.

Usually it is. If it isn’t, she almost always easily moves on. Even if she doesn’t, I still love it.

I know she talks with feeling because the subject matters, not because her ego or “identity” is emotionally invested (though even that can be good).

When people care about what they are saying, their bodies resonate with feeling.

IMO, it’s a mistake to try too hard to control that or hide that. Emotions like that stimulate the mind/brain and make us smarter.

Technology and human transformation

Most fundamental changes in human societies happen due to technological advances.

The next big change in human psychology will come from inexpensive, very sensitive brain scans.

These scans will show millions people in real-time how their brains are actually behaving and reacting. Presently unnoticed or concealed twinges of emotion will become conspicuously visible on a screen or within a hologram that surrounds our heads.

People will be able to use this technology in the company of a computer program or with a human partner. A good AI program will use brain-scan information to reveal much about us. We will learn stuff about how we actually function that very few are aware of today.

Having this knowledge will change the way we understand ourselves and our interactions with others. Rather than work almost exclusively with the vague stories we tell ourselves, we will be able to see how our brains (and bodies) actually function in real time.

The difference between our stories and how we actually function is very great. Great enough to completely change the landscape of what we now think of as human psychology.

There already exist inexpensive EEG rigs that are sort of good at measuring moods and honesty. There are also expensive ones with more capacity. Within a decade or two, these devices will be much better. An accurate lie-detector will surely be included in the consumer package.

This technology will rewrite our understanding of human psychology and remake the ways we think of human society today. If you want to get a head start on the future, learn how to do FIML now.

Micro, meso, and macro levels of human understanding

This post is concerned with the micro, meso, and macro levels of existential semiotics and communicative thought, and how those levels affect human understanding.

  • Micro levels are very small units of thought or communication. These can be words, phrases, gestures, etc. and the “psychological morphemes” that accompany them. A psychological morpheme is the smallest unit of an emotional or psychological response.
  • Meso levels lie between macro and micro levels. Longer discourse, a sense that people have personalities or egos, and the basic ideas of any culture appear at this level.
  • Macro levels are the larger abstract levels that sort of stand above the other two levels. Macro levels might include religious or scientific beliefs, political ideologies, long-term personal goals or strategies.

Most people most of the time socialize on the meso level, often with support from shared macro level beliefs or aims. For most people, the broad outlines of most emotions are defined and conditioned at the meso level. This is the level where the nuts and bolts of convention are found. This is the level that tosses the beach balls of conversation back and forth across the dinner table and that defines those balls. The meso level defines our subculture and how well or badly we conform to it. The meso level is necessary for much of social life and sort of fun, though it is by definition not very detailed or profound. It is something most people can agree on and work with fairly easily for an hour or two at a time.

Many people define themselves mainly on the meso level and judge others by their understanding of this level. Many subcultures become stifling or cloying because meso definitions are crude and tend to leave out the rich subjectivity of individuals. Macro definitions are not all that different from meso ones except that they tend to define group feelings more than meso definitions. Groups band together based on macro level assumptions about ideologies, science, religion, art, style, location, ethnicity, etc.

Since most people are unable to fully access micro levels of communication the rich subjectivity of the individual mind is rarely, if ever, communicated at all and almost never communicated well.

In other fields, micro levels are all important. For example, the invention of the microscope completely changed the way humans see and understand their world. All that was added by the microscope was greater resolution and detail in the visual sphere. From that arose germ theory, material sciences, modern biology, modern medicine, and much more.

Micro levels of communication are basic to how we understand ourselves and others. Poor micro communication skills consign us to communication that occurs only at meso or macro levels. This is a problem because meso and macro levels do not have sufficient detail and also because meso and macro levels become the only tools we have to decide what is going on. When we are forced to account for micro details with the crude tools of meso thought, we will make many mistakes. Eventually we become like the long-term cigarette-smoker whose (micro) alveoli have collapsed, destroying full use of the lungs.

Without the details of the microscope, people for millennia happily drank germ infested water. Without a way to resolve micro levels of communication, people today, as in the past, happily ingest multitudes of micro error—errors that make them ill.

Micro communication errors make us sick because we make many serious mistakes on this level and also because our minds are fully capable of comprehending the sort of detail we can find at the micro level. We speak and listen on many interpersonal levels like crude beasts when we are capable of very delicate and refined understanding.

FIML or a technique similar to it provides a method for grasping micro details. Doing FIML for a long time is like spending a long time using a microscope or telescope. You will start to see everything differently. Detailed micro analyses of interpersonal communication changes our understanding of micro communication and also both the meso and macro levels of existential semiotics and communicative thought. Microscopes allowed us to see germs in water and also to understand that some of those germs can kill us.

Is there a universal morality or basis for morality?

Anthropologists from the University of Oxford believe there are seven components or rules of human morality that can be found in all societies.

…help you family, help your group, return favours, be brave, defer to superiors, divide resources fairly, and respect others’ property, were found in a survey of 60 cultures from all around the world.

An article about this study can be found here: Seven moral rules found all around the world.

The study itself can be found here: Is It Good to Cooperate? Testing the Theory of Morality-as-Cooperation in 60 Societies.

The study concludes that the universal basis of human morality is cooperation.

Among the seven rules, bravery is defined as a moral virtue in defense of one’s group, an ultimate form of cooperation that may result in death.

Deference to superiors seems to be a virtue that supports group hierarchy.

Both bravery and deference to superiors indicate that fighting within and between groups is common.

In today’s world, obviously, many people and most Americans do not live in tribes or stable neighborhoods, so our groups have become nebulous, abstract, bound more by belief and imagination than tribal and clan and familial bonds.

In this respect, the study shows why politics—and other subjects touching on group identity—can become so polarized and so difficult to discuss rationally.

Human consciousness is supported by dynamic complex patterns of brain signal coordination

…We postulate that consciousness has specific characteristics that are based on the temporal dynamics of ongoing brain activity and its coordination over distant cortical regions. Our hypothesis stems from the common stance of various contemporary theories which propose that consciousness relates to a dynamic process of self-sustained, coordinated brain-scale activity assisting the tuning to a constantly evolving environment, rather than in static descriptions of brain function (3–5). In that respect, neural signals combine, dissolve, reconfigure, and recombine over time, allowing perception, emotion, and cognition to happen (6). (Source)

Word order and word choice affect how and what we think

A new study shows that the word order of the language(s) we speak affects how we remember spoken information and perhaps more.

An article about the study can be found here: Word order predicts a native speakers’ working memory.

The main novelty of this study is that the link between language and thought might not be just confined to conceptual representations and semantic biases, but rather extend to syntax and its role in our way of processing sequential information. The language we speak affects the way we process, store and retrieve information.

The study can be found here (no paywall): The word order of languages predicts native speakers’ working memory.

Word choice can have even bigger effects on how we think and what we think about.

For example, using the term default mode network in place of unconscious mind or the Freudian Id yields a very different kind of understanding about what people are and how they function.

If you pay close attention to your default mode network, I am certain you will find yourself making judgements about other people. I am also certain that many of those judgements will have been repeated many times in the past and without intervention from your meta-self will be repeated many more times in future.

These judgements affect how you think and feel about many things; they tend to be fundamental to the workings of our psychologies.

Often our default mode judgements include our desired punishment for the offense we have just judged: “I hope that SOB falls in the river” or however you would put it.

A wonderful side of our minds is we can see that. We can see what we are doing and even figure out ways to act on what we see.

The next time you notice yourself wishing someone would fall in the river, stop and ask yourself if that is what you really want.

I am not saying get all moral with yourself and pray for the person. I am just saying ask yourself if that is what you really want. Do you really want them in the river?

I bet most of the time, if not all, you would much rather see them repent, reform, apologize, make amends, sin no more.

If you see that, you can see there is no spiritual need for revenge or punishment. What we need and want is the betterment of the person we have judged and the betterment of ourselves.

The way we think about our real-world minds and uses of language can be changed by how we think about them.

Rene Girard’s Mimetic Theory & The Scapegoat

Rene Girard, Professor Emeritus at Stanford University, began developing his theories over 40 years ago, while researching the great stories in literature. He wanted to know what made these stories great and he discovered that they had some similarities. He further began to research the rituals and mythologies of primitive people. He noted the same common structural properties in those stories. These similarities in the world’s mythologies and rituals led to the development of his theories of mimesis and the scapegoat mechanism.
