Abstract
UMGQUBO:
Imidlalo yokudlala kwi-Intanethi ibe yinto edumileyo yokuzihlaziya, apho amadoda ahlala ephuhliseka khona kwimidlalo ye-Intanethi (IGD) xa kuthelekiswa nabasetyhini. Nangona kunjalo, umahluko ophathelene nesini okuhambelana nesini awuzange uphandwe kakuhle kwi-IGD.
IINDLELA:
Imisebenzi enqwenelekayo ye-cue yenziwa ngaphambi kokudlala umdlalo kwaye kwangoko emva kokuhlutha kwenziwa njengesixhobo esiphumelelayo sokuphumla ekugembeni xa i-Intanethi iyekiswa. Izifundo ezingamashumi alithoba anethoba ze-IGD (i-27 yamadoda kunye nabasetyhini be-22) okanye ukusetyenziswa komdlalo wokuzonwabisa (i-RGU; Amadoda angama-27 kunye nabasetyhini be-23) babonelela ngemisebenzi ye-MRI kunye nedatha ye-subjential. Uhlalutyo lokuphanda iziphumo zeqela (i-IGD kunye ne-RGU) × isini (eyindoda nebhinqa) ngamaxesha ahlukeneyo (ngaphambi komdlalo, umdlalo wangaphambili, kunye nomva kwangaphambi kokufika komnqweno we-cue-elicited kunye neempendulo zobuchopho zenziwa. Ukulungelelaniswa phakathi kweempendulo zobuchopho kunye namanyathelo e-subjential kwabalwa.
IINKCUKACHA:
Kuvavanyo lwangaphambi, lwasemva, kunye nolwangaphambi kokunxibelelana, ukusebenzisana okubalulekileyo ngokwesini ngokwamaqela (p <.001, ubungakanani beqela> ii-voxels ezili-15) zaqwalaselwa kwicala lasekhohlo ledorsolateral preortal cortex (DLPFC). Olunye uhlalutyo lweqela le-DLPFC lubonise ukuba kuthelekiso lwangaphambi kwexesha, iziphumo zinxulumene nokuzibandakanya okuncinci kwe-DLPFC kwi-IGD, ngakumbi kubafazi. Ukongeza, kuvavanyo lwasemva kovavanyo, ukusebenzisana okubalulekileyo kwaqwalaselwa kwi-caudate, njengoko abantu ababhinqileyo abane-IGD babonisa ukwenziwa okukhulu xa kuthelekiswa nalawo ane-RGU.
UKUXAXA:
Iziphumo ziphakamisa ukuba amabhinqa ane-RGU angabonisa ulawulo oluphezulu kunamadoda xa ejongene nemidlalo yokudlala, enokuthi ibonelele ngokuchasene nokukhula kwe-IGD; nangona kunjalo, nje bakuba baphuhlise i-IGD, imidlalo yabo inokudodobalisa ulawulo lwabo oluphezulu kwaye baphucule iminqweno yabo yokudlala, enokubangela kube nzima ngakumbi ukuyeka umdlalo.
IINJONGO EZIQHELEKILEYO: Ukuphazamiseka kwemidlalo kwi-Intanethi; isiqhulo; umnqweno; dorsolateral preortal cortex; ulawulo oluphezulu; isini
