Hypnotherapy and Science
Dr. Amir Raz is a professor at Columbia University in the field of neuroscience, he has spent immense amount of time studying this phenomenon, utilising the Stroop effect.
The Stroop Effect:
You’re going to read a series of two words in just a moment. What I want you to do, is to identify (as quickly as you can) the color that the word is written in.
Here we go:
How’d you do?
It is common if you took a couple of seconds in identifying the correctness in colour. As simple as this may seem the answers can be a little challenging, this is more challenging if you required to answer many simple questions one after the other. The reason is so deeply ingrained in your mind when you read, this creates a delayed response to the identification of the particular colour you are identifying.
Use of this in the study:
1. Dr. Raz divided the group into two groups.
2. One group was hypnotised and the other not.
3. The hypnotised group was given posthypnotic suggestion - seeing the words on a screen as gibberish / no sense.
4. The non hypnotised group was not under any influence of the posthypnotic suggestion.
5. The subjects were subjected to a brain scanner, subjected to test of the Stroop.
6. The group that went under the posthypnotic suggestion, the Stroop effect was null and void.
7. They identified all colours correctly instantly. The second group was slow in identifying the correct colours shown.
8. The brain scans were analysed by Dr. Raz with evidence, those under the influence of the posthypnotic suggestion revealed the visual area of the brain shutdown used to identify words and language.
