Mental Tricks

Mental Tricks are the skill to make the mind appear a certain way from which it is not. Talentless and talented can perform these.

Highlighting Memories
Keefe does this in Flashback when Fitz and Sophie are searching his memories. Keefe imagined all the memories he didn't want Fitz and Sophie to look at in a chest. He then imagined that chest whatever color he chose, in his case it was gold. All the memories he chose he didn't want Sophie and Fitz to see turned gold. Sophie and Fitz could still see these memories but followed Keefe's wishes to avoid them.

Hiding Consciousness
The Black Swan teaches their members how to hide their consciousness in a nook in their mind so it's easier and possible for Sophie to heal their minds if broken. Prentice Endal does this.

Hiding Thoughts
Mr.Forkle hides his thoughts in a series of barriers. One of which forced the searcher to go against their instincts to reach his thoughts. This did not stop Sophie and Fitz when they attempted to read Mr.Forkle's mind. The Ogre King, King Dimitar may be doing something like this. Gethen uses this.
