The constituent unit items of a numerical pattern can similarly contain records of counting, and in that case, we say counting is contained in the pattern, in that an item of the pattern can signify a counting act—the numerical pattern implies counting and becomes an assimilating or first part of the counting scheme.

Our initial hypothesis–that the verbal period is a transitional period in the same sense that counting figural unit items was for Brenda, Tarus, and James—will be thoroughly tested.
