Factor structure of intelligence test battery KOG9

Abstract

Authors of Cybernetic model of cognitive functioning designed a battery of tests (KOG9), based on the model in order to assess cognitive efficiency. Authors assert that scale's factor structure comprises the three factors: perceptive, serial and parallel processing. Results of the previous research as well as the logical analysis of the origin and content of the tests suggested the possibility that more parsimonious two-factor solution can explain the structure of the correlations among them equally well. KOG9 battery was administered to 1116 students of Faculty of sport and physical education and students from Department of Psychology in order to study its latent structure. In spite of the fact that factor congruence analyses suggested higher robustness (cross-sample stability) of the two-factor solution, results of both EFA and CFA spoke in favor of the three-factor solution. The problem of the lack of stability of the three-factor solution was located in not particularly well targeted choice of the markers of the efficacy of perceptual processing. The suggestion is to preserve the calculation of all three group scores, with some corrections. First of all, tests CF2 and/or GT7 should be replaced by some other perceptual test/tests of lower cognitive complexity. Some of the tests tapping parallel processing should be replaced by those more in line with the logic of the model.Baterija za procenu intelektualnih sposobnosti KOG9 Momirovica i saradnika dizajnirana je da procenjuje efikasnost kognitivnog procesiranja informacija na osnovu njihovog kibernetickog modela. Autori navode da faktorsku strukturu ove baterije cine faktori perceptivnog, serijalnog i paralelnog procesiranja. Rezultati prethodnih istrazivanja, kao i logicka analiza porekla i sadrzaja testova baterije KOG9, ukazali su na mogucnost da bi i parsimonicnije, dvofaktorsko resenje (koje pretpostavlja postojanje serijalnog i paralelnog procesora) moglo podjednako uspesno da objasni strukturu korelacija medju testovima kibernetickog modela. Uzorku od 1116 studenata Fakulteta sporta i fizickog vaspitanja i Odeljenja za psihologiju Filozofskog fakulteta u Beogradu je zadata baterija testova KOG9, sa ciljem razresenja ove dileme oko njene latentne strukture. Iako rezultati analize kongruencije faktora ukazuju na vecu robustnost (izmedju-uzoracku stabilnost) dvofaktorskog resenja u odnosu na trofaktorsko, rezultati konfirmatorne faktorske analize su potvrdili superiornost trofaktorskog resenja u odnosu na dvofaktorsko. Problem slabije stabilnosti trofaktorskog resenja je lociran, pre svega, u izboru testovnih markera perceptivnog procesiranja. Preporuka autora je da se nakon zadavanja baterije KOG9 i dalje izracunavaju vrednosti za sva tri grupna skora, ali i da se baterija unapredi zamenom testova CF2 i/ili GT7 nekim drugim perceptualnim testom/ testovima nize kognitivne kompleksnosti i, eventualno, zamenom nekih testova efikasnosti paralelnog procesiranja drugim testovima, adekvatnijim sa stanovista metrijske logike, kao i logike samog modela.
