Influence of age and gender on cognitive and psychomotor abilities measured by the Complex Reactionmeter Drenovac-series tests

OBJECTIVE The aim of this cross-sectional study was to examine the influence of age and gender on cognitive and psychomotor abilities measured by tests of the Complex Reactionmeter Drenovac (CRD- series). SUBJECTS AND METHODS A total of 3421 subjects (1427 men) solved three representative CRD-series tests based on chronometry, from the simplest to the most complex one: CRD311 (discrimination of the light signal position), CRD411 (complex psychomotor coordination), and CRD11 (simple arithmetic operations). The total test solving time (TTST), minimum single task solving time (MinT), number of errors, initial dissociation (D1), start (SB), end (EB), and total (TB) ballasts, as measures of wasted time at the first half, second half, and the total test time, respectively, were analyzed. RESULTS On CRD11 test, men had shorter TTST than women (134.47±56.43 s vs. 139.17±57.60 s, p=0.021), shorter SB, EB, and TB (p<0.001), and made less errors than women (2.86 ± 2.61 vs. 3.46 ± 3.33, p<0.001). On CRD311 test women had shorter TTST (33.15±7.73 s vs 33.76±8.88 s, p=0.033), shorter start, end, and total ballasts (p<0.001) than men. On the CRD411 test, men were better than women in all measured variables: MinT (0.49±0.17 s vs. 0.53±0.20 s, p<0.001), TTST (40.43±23.29 s vs. 46.33±32.17 s, p<0.001), and number of errors (11.26±10.44 vs. 13.01±12.09, p<0.001). On all three CRD-series tests, there were positive correlations between MinT and age (p<0.001) and between TTST and age (p<0.001), as well as significant increases of D1, SB, and EB with age (p<0.001). CONCLUSION Men performed better than women in simple arithmetic and complex psychomotor coordination tests, while women achieved better results in discrimination of light signal tests. Decreased cognitive and psychomotor abilities measured by the CRD-series tests, were associated with advanced age.
