Abstract: A method for psychometric assessment testing of both cognitive and motor ability to assimilate and follow instructions. The assessment method tasks a subject to assemble a subset of inter-fitting parts from a collection of parts in a specific manner as defined by an instruction set presented to the subject, and with the help of specific reference cues. A number of inter-fitting parts are placed before a subject, each bearing various labels for guiding assembly. Some of the parts are functionally similar except in dimension. Next, the subject is given a menu of the parts bearing not-to-scale illustrations of all the parts (labels omitted), and names for the respective parts. Next, the subject is given a ruler, and then a set of assembly instructions including a set of written directions for assembling a subset of the parts in a pre-selected manner by reference to part name, dimensions, and labeled indicia. The subject is instructed to begin, and an administrator times assembly.
