AI diagnoses PTSD through voice analysis

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.

Is morality a fundamental part of nature?

Viewing nature as a signaling network shows its advantage with this question.

Instead of asking where our moral sense comes from, we ask instead what makes for a good signaling network?

The answer is “good organization.”

By “good,” I mean efficient, well-made, good use of resources, easy to maintain, rational, etc.

You are a signaling network.

A well-organized you will probably tend to be morally pretty good and wanting to get better at it, depending on your conditions.

Of course some people view “morality” as whatever is in their best interests. And that is a type of moral thinking. When it is found out, though, most other people, very reasonably, do not like it.

If we view nature as the evolution of signals and signaling networks rather than as the evolution of matter, we will see that changes in signal organization are fundamental to the evolutionary process.

In this sense, it is the most ordinary thing in the world that you, a complex signaling system that is conscious, would consciously seek good organization and/or want to adapt your organizing principles, both objective and subjective, to conditions that impact you.

Conditions that impact you are signals being perceived by the signaling network you think of as yourself.

Your adaptations, both small and large, will encompass many moral considerations and choices.

Morality can be viewed as a kind of organization. The networks that make up your being must organize their relations with the world around them and other sentient beings. We make many moral decisions when we do this. These decisions are an integral part of how we are organized.

Last night I heard a drunk swearing at his friend from the street. “You fucking bastard…” etc. Not well-organized, but still he was yelling a local version of morality and this was fundamental to his networks and behavior.

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.
