Does the Thinkerer have anything to do with the subconscious, implicit memory, motivated perception, expectancy, set, attention, self-help, or similar psychological ideas? 

A treat for those (few) who enjoy pedantic abstractions. 

There are three major themes in the Thinkerer.  They are drawn from common ideas in psychology, such as those mentioned in the question.   An introductory text in psychology will present these themes from an objective and scientific viewpoint.  It will tell you about your brain in the same way another book would tell you about your digestive system.        

                                                   Objective is the view from the lab.
                                                     Subjective is the view from the head.

The Thinkerer will use a subjective viewpoint.  It is a story told by living brains to be understood by living brains. 

Theme One:  The Modular Brain.  Your brain does a lot more than you notice.   Terms like subconscious and attention point out that your brain has modules that work without your "conscious" orders.  You get to focus on what you think is important.

Theme Two:  Self-Awareness.  You can get more out of your brain if you are more aware of the quiet modules: 

Of what they can do. 
Of how to get their best work out of them. 
Of  how to hear from them. 

The Thinkerer tools will help you get better work out of those quiet modules.

Theme Three:  Self-Direction.  You can get more out of your brain if you get the relevant modules to work together on what you want to do.   The Thinkerer tools help you get your head together and keep it on track toward what you want to do.

Now pause for a moment and consider what you got out of the paragraph above. 
A. I don’t understand anything it said.
B. I thought it made sense when I read it but I have no idea what to do with it.
C. It is too abstract and I don’t like abstractions.
D. I understand exactly what it means and I know how to put the ideas into action.

If your choice is D., don’t bother reading any more.  Just go ahead and put the ideas into action.  If you chose any of the other items, you are describing what happens when you use only your language channel.

Talk is cheap and worth every penny of it.

So this page didn’t give you any idea about what to do?   All we promised in this page was pedantic abstractions.  That's no place to look for ideas about what to do.  For ideas like that, look in the Tools venue.  That will take more time.  But the tools will help you get those other brain modules to work on the job.  The modules that can figure out what to do.
