A specially designed computer program can help diagnose post-traumatic stress disorder (PTSD) in veterans by analyzing their voices, a new study finds.
Published online April 22 in the journal Depression and Anxiety, the study found that an artificial intelligence tool can distinguish – with 89 percent accuracy – between the voices of those with or without PTSD. (Source)
This tech provides a usably objective standard for measuring PTSD. This is important for diagnosing PTSD and also may lead to further voice analysis techniques for diagnosing other psychological states.

I look forward to the day when we have a lot of inexpensive technology that people can afford to buy and use at home to diagnose or simply describe a wide variety of mental states.
For now, FIML practice provides an excellent objective standard for measuring psychological states as they occur during interpersonal communication.
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.
Listening to the ranting of a friend who has Borderline Personality Disorder (BPD), I am struck by two things:
- he gives reasons for his anger
- his reasoning or abstract understanding of his predicament is ridiculous
(His rant was recorded and sent to me by a third party who is trying to help.)
With that as a starting point, consider the various ways abstract reasoning or solid abstract paradigms can compensate for or mask mental illness. Not all of it is pretty.
For example, serial killers often mask their illnesses for decades by holding fast to the appearance of normalcy while secretly indulging their madness.
Less bad are career criminals who act with savagery in less direct ways, through hit men, poisons, theft, fraud, and so on.
There is a wide spectrum between serial killers and normally inoffensive people.
It is reasonable to see all cultures as fundamentally abstract paradigms that mask and allow for madness among large groups of people.
A culture, after all, is nothing more than a Lowest-Common-Denominator system of communication; an LCD semiology. Consider how many cultures are grotesquely narcissistic.
Personality is much the same whether it conforms well or not to whichever cultural semiology it inhabits.
From this point of view, enshrining diversity only ensures a wider array of mad people. Identity politics is the same; just more ways for mad people to function, more room for them to run free; more abstract paradigms to mask their underlying chaos.
That is a decent modern restatement of the First and Second Noble Truths: life is suffering because we are crazy.
The Third and Fourth Noble Truths tell us that the way out of being crazy is to use our reason better; to understand why we are crazy; that clinging to LCD semiologies can’t ever work.
A philosophical psychologist might rightly say that a mad mind open to reason will gradually become well.
My friend with BPD can reason, but his reasoning is really bad. It’s selfish, marinated in anger, and not open to contrary views. But even he can do it if he clings to reason and evidence.
Abstract reasoning and paradigms such as Buddhism, science, other religions, atheism, psychology, or philosophy can lead us out of madness if we use them diligently.
Diligence or perseverance is one of the most important virtues in Buddhist practice. Wisdom is the most important. Compassion is probably the most famous Buddhist virtue but compassion without wisdom or diligence is not good and can even be dangerous.
Indeed, my BPD friend frequently and loudly demands unreasonable compassion from others. And that is one of the most obvious flaws in the way he thinks about himself, the way he reasons.
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.
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.

…Synchronized oscillations were first noted as far back as the 1600s, when the Dutch scientist Christiaan Huygens, known for discovering the Saturnian moon Titan, noted that two pendulum clocks hung from a common support would eventually come to tick in unison. Through the centuries, mathematicians and other scientists have come up with various ways to explain the strange phenomenon, seen also in heart and brain cells, fireflies, clouds of cold atoms, the circadian rhythms of animals, and many other systems.
Something along these lines must be happening in human communications systems, from the smallest—a single human brain/body—to the largest, the entire planet.
