State Variables
The section on the front page of the 2009 Cognistat Test Booklet entitled "Factors Potentially Affecting Test Performance" identifies important features of the test-taking environment. These state variables are frequently overlooked in both screening and more extensive neuropsychological testing. This severely limits the validity of conclusions drawn from testing. Discussion of these factors and their potential impact on testing can be found on pages 27-29 of the 2009 Cognistat Manual.


In a recent survey, Rabin, Barr and Burton found that Cognistat was among the 20 most widely used test instruments employed by neuropsychologists in the United States and Canada.
