Unconsciousness is a statistical machine. Consciousness is a sampling device.

Updated: May 29, 2022

By studying "Study of Consciousness",

I would like to think about coaching theory, such as rewriting my unconsciousness.


Presenting different images to both eyes causes unstable perception.

Look back at the binocular struggle.

If you pay attention to the two images, they will constantly alternate in your consciousness.

The sensory inputs are ambiguous and fixed, but at one point, we only notice one of the images coming in from both eyes, so we perceive them as constantly alternating.

If you turn your attention to another subject, the binocular struggle will stop.

It seems that the unconscious chooses samplings that are statistically processed only when conscious attention is directed.

A myriad of unconscious neurons estimate the accurate probability distribution for external situations,

I can say that the unconscious process is more objective than the conscious process because the consciousness decides whether to adopt it or not.

In the human brain, consciousness and unconsciousness

  • Unconscious = statistical machine,

  • Consciousness = sampling device

This division of roles applies not only to vision but also to various other areas such as language.

When perceiving an ambiguous word such as "bank", unknowingly, both meanings (bank, bank) are temporarily subject to priming.

We feel that we can only focus on one place at a time,

The unconscious mechanism of selecting an object before that is probabilistic and, at the same time, takes into account several hypotheses.

Conscious information retrieval functions as an invisible hand that arbitrarily extracts samples based on the unconscious probability distribution.

In other words, consciousness can extract the first, second, or third sample by unconscious statistical support processing.

For example, a large organization like the FBI, which has thousands of employees, has an overall amount of knowledge that an individual can barely grasp on its own. From the situation when the terrorist attacks on September 11, 2001, it is not always easy to draw out the necessary knowledge from the various ideas that each innumerable staff has. There is none.

To avoid drowning in the vast ocean of trivial facts, the President made decisions based on summaries that were sucked up and edited through hierarchical organizations, and the "common wisdom" thus gained was one of them. You have to let the press secretary announce it.

"As a massive organization with a large staff of 100 billion neurons, the brain needs a similar information summarization mechanism. The function of consciousness sums up the latest external conditions and then. I think it's about simplifying perception by communicating consistently to all other areas of memory, decision making, and behaviour.

This conscious summary must be integrated and stable.

It would be too ridiculous if the President had to understand the myriad messages that the FBI sent one after another in the event of a national crisis, each containing a piece of truth.

Similarly, the brain cannot process low-order input data that flows like a rage.

Individual information needs to be edited into a consistent story.

Like the summary of the situation referred to by the President, the conscious summary must be written in a "language of thought" and contain an abstracted interpretation of the outside world that is sufficiently abstracted to allow information exchange with intentional and decision-making mechanisms. It doesn't become.
