As an individual is found lower and lower on this chart, so is his alertness, his awareness and his ability lower and lower.

The simplest thing to know about this scale is that people find it difficult to respond to communication which is too far above where they are stuck. If you try to help someone in apathy by talking to them in enthusiasm, you will probably not have much success. The gap between such extremes is not easily bridged unless you understand the Tone Scale.
