1. A writer with heavy pressure and a vertical slant.
Heavy pressure= strong emotions and vertical slant= trying to hold emotions back. This writer is usually the one who keeps his wits about him. When "all hell breaks loose," his head rules. He will not be as emotionally responsive as a right slant writer and will "keep cool". This "heavy pressure-vertical slant" writer won't be able to keep his cool all of the time. When his emotions get the best of him he may "fly off the handle" at unpredictable times.
2. A person with light pressure writing (not much emotional or physical energy) and a left slant (tries to avoid emotional situations). This person will be emotionally withdrawn, cold, indifferent and self centered.

The leftward slant is indicative of people who are emotionally unexpressive, introverted, and even selfish. They literally "pull back" towards themselves when they utilize a left hand slant. Left hand slant is the hardest slant to write with. Using this choice is due to emotional withdrawal and repression. They can be defiant, and very difficult to deal with. They just don't trust other people and don't want them in their life. Thus they make difficult relationship partners. The farther the writing sample leans leftward; the more reclusive the person is. Left slanted writers are "takers" not "givers"
Leftward slant writers are often writers, artists, and poets. These people will often show great emotions in their creative works. I interpret this as an exhibition of their inability to express themselves emotionally in reality; and therefore they sublimate these strong emotions in their writing or art.
Extreme leftward slant divulges a hermit, who mistrusts everyone. These few people are extremely difficult to have any relationships with whatsoever. They are cold and completely emotionless. They are insensitive.
