Multitechnique-Multimethod Matrix Methodology for Construct Validation and its Application for the Construct of Cognitive Structure

The hypothetical construct of cognitive structure encodes human knowledge internally, and two-stage probes are used to define it operationally to obtain external representations of cognitive structure. First, a proximity matrix is constructed that encodes subjects' responses on a task, and secondly, a scaling method is applied to the proximity matrix to yield a representation of cognitive structure in the form of concept categories or spatial...
