How working memory works and doesn’t work

A new study on working memory has some intriguing insights into how working memory works and how it doesn’t work.

It’s widely known that when working memory is overtaxed, confusion results, skills decline, while feelings of frustration and anger may arise. The reason for this seems to be:

Feedback (top-down) coupling broke down when the number of objects exceeded cognitive capacity. Thus, impaired behavioral performance coincided with a break-down of Prediction signals. This provides new insights into the neuronal underpinnings of cognitive capacity and how coupling in a distributed working memory network is affected by memory load. (Working Memory Load Modulates Neuronal Coupling)

A well-written article about this study contains the following diagram and explanation:

This article—Overtaxed Working Memory Knocks the Brain Out of Sync—also contains the following passages and quote from one of the study’s authors:

Miller thinks the brain is juggling the items being held in working memory one at a time, in alternation. “That means all the information has to fit into one brain wave,” he said. “When you exceed the capacity of that one brain wave, you’ve reached the limit on working memory.”

The prefrontal cortex seems to help construct an internal model of the world, sending so-called “top-down,” or feedback, signals that convey this model to lower-level brain areas. Meanwhile, the superficial frontal eye fields and lateral intraparietal area send raw sensory input to the deeper areas in the prefrontal cortex, in the form of bottom-up or feedforward signals. Differences between the top-down model and the bottom-up sensory information allow the brain to figure out what it’s experiencing, and to tweak its internal models accordingly. (Emphasis added)

Working memory works via connections between three brain regions that together form a coherent brain wave.

Notice that “an internal model of the world,” which is a “top-down signal” within the brain wave feedback loop, predicts or interprets “bottom-up” sensory input as it arrives in the brain.

I believe this “top-down signal” within working memory is the reason FIML practice has such enormous psychological value.

By analyzing minute emotional reactions in real-time during normal conversation, FIML practice disrupts the consolidation, or more often the reconsolidation, of “neurotic” responses. (Disruption of neurotic response in FIML practice)

FIML optimizes human psychology by helping partners intervene directly into their working memories to access real-world top-down signals as they are happening in real-time. Doing this repeatedly reliably alters the brain’s repository of top-down interpretations, making them much more accurate and up-to-date.

The model of working memory proposed in this study also explains why FIML can be a bit difficult to do. Partners must learn to allow a FIML meta-perspective or “super top-down” signal to quickly commandeer their working memories so that analysis of whatever just happened can proceed rationally and objectively. It does take some time to learn this skill, but it is no harder than many other “automated” skills such bicycling, typing, or playing a musical instrument.

Our psychologies are unnecessarily confined within narrow ranges of meaning and understanding

Human psychology is greatly affected by human language. Since humans normally use language rather crudely and almost always are confined within meanings already established in language, their psychologies are fundamentally both crude and unnecessarily confined within narrow ranges of meaning and understanding.

This causes emotionality, discord, dependence, frustration, anger, and violence. Our normal uses of language often stimulate basic instincts that we either have to control or be controlled by.

I usually discuss this problem as it occurs during interpersonal conversation, where it is generally most serious and where our “personalities” are generally formed. But it also exists in texting, emails, news stories, and even scientific peer reviewed papers.

The basic underlying problem is we do not communicate well, almost no one does. Even very articulate, well-educated, intelligent people with good upbringings and admirable personalities have this problem. In fact, they often have it even worse than everyone else because their considerable skills have trapped them even worse.

The trap is using established meaning or interpretation to override mistakes in interpersonal communication. The established meaning can be learned from others or self-generated. Either way, when it is used to override mistakes in communication (and this happens often) the person is trapped in a labyrinth of false references: the lived and learned matrix of their personality; the neuronal structures of idiosyncratic memories and behaviors that constantly misguide the sufferer through a tautological existence.

When data is bad the output will be bad. When interpersonal data is bad, and far too much of it is, the output in speech, listening, and cogitating will be bad. When everyone is like this, the output will be horrendous. Look around you at our world as it becomes less truthful and more absurd daily. The root cause is massive amounts of uncorrected bad data at all levels of society.

My contribution toward fixing this mess is FIML, which deals “only” with the enormous problems of close or intimate interpersonal communication.

When two people do FIML conscientiously, all of their problems born of long histories of many mistakes can be cleared up. If you want to do this, if you want to optimize your being; find a good partner and do FIML. As of today, there is no other way. If you can see the problem, you will understand why FIML works. If you do FIML even without fully understanding it, you will still fix the problem and will eventually come to see how it’s not just your problem: all people everywhere have it and have always had it. I do not know why I am the first person to provide a solution to it.

The problem is very obvious but it is so big and widespread, people either do not see it or believe it cannot be fixed.

FIML is especially good for and accessible to very sensitive people who pick up on communication signs much more than most people and who love having those sensitivities but do not know how to manage them well

The tragedy of Superman’s original Lois Lane, the Hollywood star who ended up homeless, eating out of trash cans with a life in turmoil

In the early days of her international stardom, in the wake of the Superman box office behemoth, she described to Rolling Stone ‘a constant sense of conflict: if I think about what I believe is important, I’ll be crazy; and if I don’t think about it, I find myself denying, denying, denying in order to be normal.’
