The appearance of my brain that can only be aware of one thing

Updated: May 29, 2022

(In cognitive science) coaching rewriting the unconscious is a powerful way to achieve your goals.

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.

By immersing yourself in intellectual work, such as when you are concentrating on reading

You may have experienced a situation where you were isolated from your surroundings.

When the consciousness is occupied, other information waits in the unconscious buffer.

In addition, the information stored in the buffer is internal noise, distraction, and other input information.

The appearance of my brain that can only be aware of one thing,


A series of cards will appear on your computer screen.

The experimenter instructs you to remember the first letter that appears.

I didn't know the first letter because the letters appeared almost immediately.

This phenomenon is called "blinking attention".

By the cards coming out one after another,

The consciousness becomes saturated temporarily, and the brain becomes indecipherable.

We can confirm that all textual information, including unconscious ones, is transmitted to the brain using brain imaging.

It's a mundane expression, but it's in the state of being "in my head."

All information has reached the realm that governs the early stages of vision. However, it may also reach deep into the brain.

Some parts of the brain "know" when the letters were presented,

This information is unconscious for some reason.

To be consciously perceived, the letter must go to another awareness stage.

Only one piece of information passes through it, and the other is unperceived and dropped.

The "Binocular Struggle" revealed a conflict between two images presented simultaneously.

See yesterday's blog.

On the other hand, in "blink of attention", the same kind of competition as "binocular struggle."

It turns out that it happens between two images presented in the same place.

"Psychological refractory period"

The work of consciousness seems to be unable to keep up with the speed of the image displayed on the screen.

We feel like we are "seeing" all the numbers and letters, even when looking vaguely.

When you memorize one character, the other characters are temporarily invisible.

In everyday life, I don't feel any problems in perceiving two things that usually happen simultaneously.

For example, you can listen to the horn while looking at the road signs.

Psychologists call this situation a "dual-task".

At this time, while the first item (= see the road sign) is processed,

The second item (listening to the horn) is placed in an unconscious buffer,

It has been waiting there until the processing of the first item is complete.

We are not consciously processing two different unrelated events at the same time.

In reality, while one is conscious, the other is waiting.

The waiting causes a processing delay, called the "psychological refractory period".

Usually, we are unaware of this unconscious waiting time.

Instead, it is unnoticed in the first place.

Consciousness is occupied by other work, so

It cannot be recognized that "consciousness's perception of the second item is awaited".

In addition, the timing of events is wrong.

Once you focus on the first task and then think about when the second item appears, you're going back to the point where you're conscious and misunderstanding the timing.

Objectively, even if two inputs are simultaneous, we can't capture their simultaneity and feel that one of the first attentions came first.

This subjective delay is due to the slowness of consciousness, and "blink of attention" and "psychological refractory" are psychological phenomena that are strongly related to each other.

It is possible that both "blinking attention" and "psychological refractory period" occur during the performance of a double task.

It has already been confirmed by experiment.

I will introduce an experiment in which the brain cannot see things tomorrow.
