Povezanost inteligencije i brzine kognitivne obrade reči srpskog jezika

Abstract

Ispitivan je odnos brzine obrade infleksionih oblika reči srpskog jezika i inteligencije. Inteligencija je procenjena baterijom od 9 testova, pri čemu su izdvojeni faktor neverbalne i verbalne sposobnosti. Pokazatelji obrade infleksionih oblika reči bili su intercept i nagib u regresiji prosečnih vremena obrade (ms) oblika imenica na količinu informacije (bitovi) koju oni nose. Intercept je odražavao vreme leksičke pretrage i davanje odgovora, dok je nagib odražavao vreme potrebno da se obradi jedan bit morfološke informacije. Ispitanici su podeljeni u 8 grupa (prema medijani odnosno donjem i gornjem kvartilu oba faktora inteligencije). U osam odvojenih regresionih analiza (svaka grupa posebno) sa četiri kontrasta (grupe podeljene prema medijani, odnosno kvartilima oba faktora inteligencije), intercepti su bili različiti u svim poređenjima, dok su razlike u nagibima dostigle značajnost samo za grupe sačinjene prema verbalnoj sposobnosti. Razmotren je relativni doprinos procesa čije trajanje odražavaju intercept i nagib faktorima inteligencije.

Relation between processing speed of Serbian inflected noun forms and intelligence was investigated. Intelligence was assesed with battery of 9 intelli-gence tests. Factor of non-verbal and verbal ability were extracted. Processing of inflected noun forms was indicated by intercept and slope from regression of averaged processing latencies (ms) for four forms on the amount of information (bits) carried by those forms. While intercept indicated lexical search and response latency, slope indicated time to process one bit of morphological information. Subjects were divided into eight categories (bellow and above the median, and bellow 25. and above 75. percentile, with respect to score on each of the ability factors). In eight regression analyses with four comparisons (median and percentile contrast, by two intelligence factors) intercepts were different in all comparisons, while differences in slopes reached significance only for groups which differed in verbal ability. Relative contribution of processes indicated by slope and intercept to intelligence factors was discussed.
