COGNITIVE ASSESSMENT SYSTEM (CAS)– DESCRIPTION OF THE PROCEDURE AND EXPERIENCE WITHIN SERBIAN POPULATION
Main Article Content
Abstract
The aim of this paper is to educate local professionals about the cognitive test that, according to the authors' knowledge, has not yet been applied to our population, and to present psychometric properties of the test within a pilot study. Cognitive Assessment System; (CAS) is intended for measuring cognitive performance in children aged 5 to 17 years and is based on the famous PASS theory and functional units of the brain. According to this theory, the three „functional units“ form the basis of four factors influencing the efficiency of cognitive processes: planning, attention, simultaneous and successive processes. CAS consists of a total of 12 subtests, with 3 subtests for each factor of cognition (standard form of battery), or 8 subtests, with 2 subtests for each factor (basic form of battery). The results of the first administration of the test in Serbian population of preschool children show that the metric properties of the CAS is satisfactory, that the distribution of scores are close to normal (when 8 subscales of the basic form of battery was applied). CAS subscales significantly correlate with each other and form a tri-factor but the four-factor latent structure of the measured area is also discussed in this paper. The practical implementation of the CAS test is reflected in the assessment of cognitive processes that can contribute to the the child's further development and education.
