UKUPHAWULA: njengoba ucwaningo luthi - "Ukwenza izinqumo okungalungile kuwuphawu lokulutha, kungaba ezintweni noma emisebenzini." Ukukhetha okungalungile nokuntuleka kokuzithiba kusho ukuthi i-cortex engaphambili ilahlekelwa yimpi. Lokhu kungukuzenzisa. Lokhu kwenzeka ekugembuleni kwe-pathological nokulutha kwezidakamizwa. Kungenzeka kwenzeke ngokulutha kocansi.

abstract
INJONGO: Ukwenza izinqumo okungekuhle kuwuphawu lokulutha, kungaba ezintweni noma imisebenzi ethile. Ukusebenza esivivinyweni esisetshenziswa kabanzi sokwenza izinqumo, i-Iowa Gossip Task (IGT), kungabandlulula izilawuli kubantu abanezilonda zangaphambi kwezindondo zangaphambili, ukuxhomekeka kwezidakamizwa, nokugembula kwe-pathological. Izifundo ze-Positron emission Tomogra (PET) zibonisa ukuthi abantu abathembele kwizidakamizwa bakhombisa umsebenzi oguquliwe wokuqala kulomsebenzi. Lapha sivumelanise i-IGT kwisilungiselelo se-fMRI sokuhlola i-hypothesis enesiphene ekusebenzeni kokuphamba kwangaphambi kokucabanga kwangaphambi kokukodwa okuhambisana nezinqumo ezingalunganga ezibandakanya ubungozi kepha zingahluka ngokuya ngokuthi ukuxhomekeka kwento kuhambisana yini nezinkinga zokugembula.
INDLELA: Izilawuli ze-18, ama-14 ancike kubantu ababhemayo (SD), kanye ne-16 SD enezinkinga zokugembula (SDPG) ehlelwe yi-fMRI ngenkathi enza uhlobo olushintshiwe lwe-IGT.
RESULT: Ukwahluka kweqembu kwaqashelwa ngaphambili kwendawo yezindondo, yangaphambili yangaphambili, ne-cortex ephambili ngesikhathi sokuthatha izinqumo. Ukulawulwa kubonise umsebenzi omkhulu kunabo bonke, kulandelwa yi-SDPG, kulandelwe yi-SD.
ISIPHUMELELO: Imiphumela yethu isekela i-hypothesis ethi ibonakele ekuqhubekeni kwangaphambi kokucubungula kwangaphakathi kwe-medial kuholele ezinqumweni ezingalunganga ezibandakanya ubungozi. Ukuncishiswa komsebenzi wokuqala owenziwa ngesikhathi sokuthatha izinqumo kubukeka sengathi kunciphiswa ubukhona bezinkinga zokugembula futhi kungakhombisa imemori yokusebenza engasebenzi, ukuqashelwa komvuzo wokuvuselela okuthile, noma ukuphinda usebenze ngokuthile kubantu abancike ezintweni.
