Consciousness can sustain thinking, but it cannot be unconscious.

Updated: May 29, 2022

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

This series of blog posts are my study notes.


The theme of this time is "Consciousness can sustain thinking, but unconsciousness cannot sustain thinking", but intuitively, we confirm the relationship with the "brief system" in cognitive science. is needed. ・ ・ This will be my homework for a while.

Whether it's a rabbit or a human, the eyelids close immediately when the air is blown into the eyes.

A conditioned reflex will occur if you make a short warning sound just before blowing air, similar to Pavlov's conditioning.

The reflex reaction that closes the eyelids is rapid. But is it conscious or unconscious? Surprisingly, it depends on whether there is a time lag.

  • "Delay conditioning" ... Conditioning. The warning sound continues to sound until the air is ejected. Sound and air stimuli overlap in the brain for a short time.

  • "Trace conditioning" ... Not conditioned. The warning sound is shortened, and there is a time lag between the warning sound and the air.

As confirmed by brain images, in "delayed conditioning", subjects activate the prefrontal cortex and hippocampus.

  • It suggests that consciousness has played a role in learning over time in the process of evolution.

  • The system formed by tissues such as the prefrontal cortex and the hippocampus that interconnects it plays an essential role in bridging the time lag.

  • I can say that consciousness connects some of the past experiences to the present sensory data and even projects it into the future.

The memory trace conditioning test can be an excellent experiment in that We can use it for experiments ranging from infants to monkeys, rabbits, and mice.

In mice, the anterior brain region corresponding to the human prefrontal cortex is activated.

Measuring the duration of the subconscious activity, we find that it is impossible to prolong unconscious thinking in time.

Thoughts under scrutiny last only for a brief period.

Visible images are long-lasting, while invisible images only affect thinking quickly.

After about a second, the unconscious activation generally drops to undetectable levels.

Numerous experiments have shown that the stimulus under scrutiny diminishes sharply.

"Consciousness can sustain thinking, but unconsciousness cannot."

In the future, I will not forget to look at this theme concerning the brief system and the rewriting of internal expressions.
