ABSTRACT
Which approaches to examining CPS might a researcher choose? In addition to the experimental manipulation of variables, the researcher might decide to adopt a single-case analysis. The latter approach has as its goal the exact reconstruction of an individual solution approach to a given problem (see Kluwe, this volume). Or the researcher might attempt to construct an artificial system that reproduces subjects' behavior as accurately as possible (i.e., computer simulation of cognitive processes; see Dorner & Wearing, this volume). Although all of these represent reasonable approaches to studying CPS, I am concerned with the first possibility only, that is the experimental manipulation of variables that are deemed important for our understanding of CPS. Next, I shall discuss some pros and cons of the experimental approach.
