• Thought train length. Every person has their own typical thought train length. The thoughts are internalized reality concepts, further concept alignment, and internal dialogue (linguistic thought). The thought train length determines how extensive are the options that a person recognizes to a given external reality. The potential concepts and potential task lists are functions of the thought train length.
• Radius of interest or thought train locus. Each person has a particular set of interests that guides their attention, that they analyze further, and that they direct their attention to gathering of further external reality data.

  From these two ideas, we see that from a concept drawn from an external reality, a particular person will reason to a certain depth then rotate to a different concept.

 

  
 Lastly, emotion can be usefully discussed as a shortening of thought train length, a narrowing of the radius of interest, and a changing of importance among the priorities for determining action (i.e. how immediately must a need be fulfilled, at what cost, etc.).
