A szkizofrénia neurokognitív vizsgálatai ellentmondásos eredményekkel szolgáltak a betegségben tapasztalható memóriazavar jellegével kapcsolatban. Jelen vizsgálatunkban a KNOWLTON és munkatársai által leírt (1994) valószínűségi kategorizációs feladatot alkalmaztuk a tudatos és kontrollált explicit, valamint a tudattalan és automatikus implicit memóriafolyamatok tanulmányozására. Eredményeink szerint a szkizofrén betegek az egészséges kontrollszemélyekhez hasonlóan képesek voltak kategorizációs teljesítményüket növelni a inger-válasz asszociációs folyamat során. Ezzel ellentétben a kategóriatagok tudatos azonosításánál jelentős károsodás volt tapasztalható. Adataink az explicit memóriafunkciókhoz kapcsolódó mediotemporális területek károsodására utalnak, míg a neostriatális implicit rendszer viszonylagosan megkíméltnek mutatkozott.
