If the consciousness doesn't know, but the unconscious knows the loss, your hands may sweat

Updated: May 29, 2022

By studying "Study of Consciousness", I would like to think about my method and the coaching theory, such as unconscious rewriting.

This series of blog posts is my study note.

Research has shown that the Grand Master of Chess can evaluate the placement of pieces and memorise the details by automatically dividing the board into meaningful components and analysing them at a glance. It proved.


I think the previous Hadamard theory is correct from my own experience.

However, it cannot be called science without verifying this.

  • Isn't it a story that was beautified later by the uplifting discovery?

  • Can you unknowingly solve complex problems?

Antoine Bechara of the University of Iowa has developed a gambling task to investigate mathematical intuitions about probabilities and numerical conjectures.

Subjects will be given four decks and $ 2000.

When you flip the card, you will see a message that is advantageous or disadvantageous to the subject. ("Get $ 100", "Pay $ 100", etc.)

The subject selects a deck to draw a card to maximise the final profit.

The subject is not informed,

Two of the four decks are designed to make a lot of money at first but start to pay more and eventually make a lot of losses.

The other two decks alternate between moderate profits and payments, but profits can be accumulated little by little.

At first, the subject randomly draws cards from the four decks.

However, you will gradually begin to use your conscious intuition, and eventually, you will be able to report which mountain is good or bad.

Here Bechara focused on the period "before intuition."

During this period, which corresponds to the mathematician's hatching stage, subjects already have a lot of evidence about the four decks but still, randomly draw cards from all piles and from which pile to draw. They claim to have no clue.

However, just before pulling from a bad deck, the subject's hands sweat and the current on the skin increases.

A weak current that is completely unnoticeable to the subject is passed between the two electrodes, but the more sweating, the better the draft. It shows that the subject's brain has already detected a high-risk deck and is producing some insect stigma below the threshold.

This alert is thought to be caused by the action of the ventromedial prefrontal cortex (vmPFC).

This vmPFC is an area of ​​the brain specialising in unconscious value assessment.

Brain images also show precise activation in this area.

People who are damaged will sweat more after pulling the card and knowing the wrong results.

Bechara's research shows that changes in these areas function unconsciously.

In some cases, even though we think we make arbitrary decisions,

our actions are guided by unconscious intuition.
