The rest of the chapter deals with how three simple factors (in italics, page 124) lead to various forms of thought (daydreaming and total, partial, and focalized recall). Note the four factors that affect what follows what in partial recall. Another interesting section is that on "volountary trains of thought" starting on page 138. Note the way in which cognitive structure allows for the searching of a missing solution.
Sonntag describes the adaptive advantages that learning sequences can yield and then moves towards integrating sequence learning into the building of a cognitive map. The included quotations provide a nice summary of the main points.
