Abstract

Nalazi dosadašnjih istraživanja pokazuju da kognitivne sposobnosti slabe s dobi. Stoga je cilj ovog istraživanja bio ispitati učinke treninga ažuriranja u radnom pamćenju na kapacitet radnog pamćenja i fluidno rezoniranje. U istraživanju je sudjelovala 41 zdrava odrasla osoba te su sudionici po slučaju bili raspoređeni u eksperimentalnu skupinu, koja je sudjelovala u treningu ažuriranja (afektivnim n-unatrag zadatkom), i aktivnu kontrolnu skupinu, koja je sudjelovala u komunikacijskom treningu. Sudionici su u dvije točke mjerenja, prije i nakon treninga, rješavali neadaptivni afektivni n-unatrag zadatak (mjera bliskog transfera), zadatak raspona operacija te Cattellov kulturalno nepristrani test inteligencije (CTI-2) (mjere dalekog transfera). Trening se sastojao od 20 sesija raspoređenih kroz 10 tjedana, tempom od 2 treninga tjedno. Rezultati složene analize varijance su pokazali da postoji značajni interakcijski učinak točke mjerenja i skupine na rezultate afektivnog n-unatrag zadatka ažuriranja. Pritom eksperimentalna skupina postiže više rezultate na posttestu u odnosu na rezultate na predtestu, dok u aktivnoj kontrolnoj skupini nije došlo do takvog poboljšanja. Međutim, interakcija točke mjerenja i skupine za rezultate zadatka raspona operacija nije statistički značajna. Značajna interakcija nije utvrđena niti u Cattellovom kulturalno nepristranom testu inteligencije (CTI-2). Rezultati pokazuju postojanje bliskog, no ne i dalekog transfera učinaka treninga ažuriranja na mjere kapaciteta radnog pamćenja i fluidnog rezoniranja.

Abstract (english)

Previous research has shown that cognitive abilities decline with age. Therefore, the aim of this study was to examine the effects of working memory updating training on working memory capacity and fluid reasoning. The research included 41 healthy adult participants, randomly assigned to either experimental group, which participated in updating training (using affective n-back task), or the active control group, which participated in communication skills training. Participants completed a non-adaptive affective n-back task (near transfer measure), operation span task and Cattell culture fair intelligence test (CTI-2) (far transfer), before and after the training. There were 20 training sessions distributed over 10 weeks, with two training sessions per week. The results of two-way ANOVA showed a significant interaction effect of time and group on the results of affective n-back updating task. The experimental group had higher results on posttest compared to their pretest results, while there were no such improvements in the active control group. However, the time and group interaction for the operation span task results was not statistically significant. There was also no significant interaction found for the Cattell culture fair intelligence test (CTI-2). The results confirm only near, but no far transfer of updating training effects to measures of working memory capacity and fluid reasoning.
