Abstract

Flynn-efekt opisuje opaženi porast prosječnih rezultata testova inteligencije između kohorta. Ovo istraživanje ispituje postojanost Flynn-efekta na hrvatskim kohortama od 1986. do 2004. godine koristeći Cattellov kulturalno nepristrani test inteligencije. Podaci IQ-a za N = 4223 sudionika prikupljeni su analizom arhivske građe prijašnjih selekcijskih testiranja Hrvatske kontrole zračne plovidbe za poziciju kontrolora zračnog prometa. Uzorak je sačinjen od 72.5% muških sudionika, ograničenog raspona starosti od 20 do 28 godina. Istraživanje također ograničava utjecaj čimbenika poput spola, starosti i razine stručne spreme na rezultate IQ-a. Analize su pretežito provedene na kohortama grupiranim u četiri grupe prema polovicama desetljeća. Utvrđeno je da odnos kohorte i IQ-a moderiraju spol i razina stručne spreme. Rezultati pokazuju statistički značajan porast fluidne komponente IQ-a među uključenim kohortama veličine od otprilike 0.3 IQ boda godišnje, što je u skladu s hipotezom rasta IQ-a prema Flynn-efektu. Nalaz je moguće generalizirati na iste kohorte opće hrvatske populacije, iako je veličina efekta uvjetovana specifičnostima i ograničenjima uzorka korištenog u istraživanju. Sukladno dobivenim rezultatima, potrebna je potencijalna restandardizacija i normiranje Cattellovog testa inteligencija za hrvatsku populaciju.

Abstract (english)

The Flynn effect describes secular increases in the average intelligence test scores between cohorts. This study examines the existence of the Flynn effect in Croatian cohorts from 1986 to 2004 using the Cattell's Culture Fair Intelligence Test. IQ data for N = 4223 participants was collected by analysis of archival material from previous selection tests conducted by the Croatian air traffic control for the air traffic control officer position. The sample consisted of 72.5% male participants, with a restricted age range of 20 to 28 years. The study also restricts the influence of factors such as sex, age, and education level on IQ scores. Analyses were primarily conducted on cohorts grouped into four groups by decade halves. A moderation effect of sex and education level on the relationship between cohorts and IQ was found. The results indicate a statistically significant increase in the fluid IQ component among the included cohorts, with gains of approximately 0.3 IQ points per year, which is consistent with the IQ growth according to the Flynn effect hypothesis. The found effect can be generalized on the same cohorts of the general Croatian population, although the effect size is conditioned by the specific characteristics and limitations of the study sample. Based on the obtained results, potential restandardization and norming of the Cattell's Culture Fair Intelligence Test for the Croatian population is necessary.
