Forty-nine college students were instructed to perform either a series of four maximal voluntary contractions (sincere) or a series of four submaximal (deceptive) contractions. The subjects were retested 24-48 hours after the initial test session. Data from both test sessions were recorded, displayed, and analyzed using segmental curve analysis. The coefficients of variation were computed for each test variable. The grand mean coefficient of variation for the sincere condition was .31 ± .02 compared to the grand mean coefficient of variation for the deceptive condition which was .77 ± .11 (p < .01). Coefficients of variation were used to predict group membership. The prediction equation accurately classified 92% of the sincere condition and 64% of the deceptive condition.vii, 105 leavesBTDapplication/pdfenIn CopyrightLD5655.V855 1992.S768Grip strength -- TestingMalingering -- TestingSegmented Curve Analysis (Computer Program)Thesishttp://scholar.lib.vt.edu/theses/available/etd-09122009-040415/
