The Influence of the Method and Instrument of Measuring Intelligence on the Assessment of the Dynamics of Cognitive Functions of Employees

Abstract

<p style="text-align: justify;"><span lang="EN-US">The article provides empirical material confirming the hypothesis that the so-called age-related decline in intelligence is not observed in all people and not always. As a result of the ascertaining experiment, it was revealed that this negative effect depends on the type of experimental design and on the method of psychological measurement of variables. It is determined that longitudinal and cross-sectional plans provide different contradictory information. It was revealed that respondents with an initially high intellectual level engaged in activities related to scientific and creative research show high results throughout their lives. However, certain cognitive mental processes that require high speed of realization become more difficult for a person with age. Memory capabilities are decreasing. There is also a decline in the field of visual perception. But the intellectual actions that are used in solving everyday or professional tasks continue to be productive. Our research was conducted with the aim of experimentally verifying the theoretical position about the falling ratio of age and indicators of tests for assessing the cognitive abilities of personnel. In a mixed sample of 1,721 respondents, the results of intellectual ability testing were compared using SOT tests, SPM, Analogies, Dictionary and TOZ, distributed into three evaluative target groups: the sphere of logical and figurative theoretical thinking, functions of combinatorics and mental construction, verbal and semantic functions of thinking.</span></p>
