Rectifying the Inconsistent Administration Procedures of the Cognistat Constructional Ability Subtest

Abstract

The Cognistat is one of the most widely used psychometric instruments to quickly assess higher cerebral functioning. However, when administered according to the manual, the constructional ability subtest yields results that are confounded by other cognitive processes, as well as blemished by intra-test inconsistencies. Such issues decrease the validity, and ultimately the utility, of this screening device. Suggestions for rectifying these shortcomings are presented.
