Summary of Comprehension of Locational and Temporal Relationships

By — Pearson Allyn Bacon Prentice Hall
Updated on Jul 20, 2010

Temporal terms such as when, before, since, and while can convey information on the order, duration, and simultaneity of events. The order of acquisition of these terms is related to their use and to the concept each represents. In general, words of order, such as after and before, precede words of duration, such as since and until, used with the progressive verb tense (eating, running, jumping). These, in turn, precede terms of simultaneity, such as while. This hierarchy reflects a sequence of cognitive development.
