Question

In a study described in the critical thinking box titled "is hypnosis a special state of consciousness?" in the text hypnotized volunteers were instructed to look at a photograph of colored rectangles and mentally "drain" the color out of the photograph so they would perceive only shades of gray. when they did as directed what did pet scan images reveal about their brain activity?

Answer 1

In the described study "is hypnosis a special state of consciousness?" in the text hypnotized volunteers were instructed to look at a photograph of colored rectangles and mentally "drain" the color out of the photograph so they would perceive only shades of gray. Some brain zones stopped working because they were induced to be inhibited. So the PET scan revealed that the activity in these brain zones stopped.

Step-by-step explanation:Hypnosis is an induced state of mind in which the subject under hypnosis will perform the tasks the hypnotist instructs him or her. In this case, we know indirectly that the purpose of the Hypnotists conducting the study was to make the subjects to watch an image composed of color structures and that they hypnotized them to drain the color of those images to see what happened in their brains. First of all the elaboration of the text is pretty bad because we only receive indirect glimpses of what could be happening so they need to fix it. Then, they don't really state purposes, just leave us to create assumptions, which is extremely bad. But the answer is that the brain zones creased activity and that is why the PET scan showed them decreasing in color.

Answer 2

PET scan images showed an increased activity in the colour regions of the brain.
Hypnosis is a state of human consciousness which is characterized by increased and focused attention, weakened peripheral awareness and an increased capacity to respond to suggestion. This explains the results of the PET scan since hypnotized individuals easily responded to the suggestion of "removing" the colour from the images. In an effort to actually do that, the colour regions of their brain increased their activity.
