Abstract
Nokuba ithathwa njengento eyimikhwa njengemikhwa yokuziphatha okanye ukungalawuleki, i-intanethi yokudlala (IGD) icingelwanga ukuba inxulumene nolawulo lokuqonda okungalunganga. Ukuziphatha ngokukuko okusebenzayo kubandakanya umsebenzi olungelelanisiweyo wothungelwano lobuchopho abakhulu, nangona kunjalo, nokuba unxibelelwano phakathi kwezi nethiwekhi ngexesha lokuphumla kolawulo lokuziphatha kwengqondo eguqulweyo kwi-IGD ulutsha luhlala lungacacanga.
Ulutsha olungamashumi amabini anesibhozo ulutsha lwe-IGD kunye namashumi amabini anesihlanu eminyaka-, isini-, kunye nolawulo oluhambelana nemfundo lwempilo oluthathe inxaxheba kwisifundo sethu. Umsebenzi wegama le-Stroop color-waqhutywa ukuvavanya intsilelo yolawulo lwengqondo kwi-IGD yolutsha. Umsebenzi woqhagamshelo olusebenzayo kunye noPhononongo loKwenza isengozi kwaqeshwa ukuze kuphandwe unxibelelwano olusebenzayo nolusebenzayo ngaphakathi naphakathi kokuthambeka, ulawulo oluphezulu, kunye nenethiwekhi yendlela engagqibekanga.
Ngeli xesha, ukucingiswa kwe-tensor imaging kwasetyenziswa ukuvavanya ukuthembeka kwesakhiwo sokunxibelelana kwenethiwekhi engaqhelekanga. TUxhulumaniso olungaqhelekanga olusebenzayo phakathi kweenethiwekhi zolawulo oluphezulu kunye nokunxibelelana okusebenzayo kuthungelwano lwe-salience kwi-IGD yabakwishumi elivisayo. Ngapha koko, intsebenzo engalunganga phakathi kolu nxibelelwano lubini yaqwalaselwa.
Ukongeza, sichonge i-anisotropy ecekeceke yenethiwekhi yokuhamba kwesitayile, amaphecana enkonzo yolawulo esembindini, kunye nenethiwekhi (i-anterior cingulate cortex-ekunene dorsolateral prewardal cortex trwaysex) indlela kwi-IGD yabantu.
Ngokucacileyo, siqwalasele unxibelelwano olubalulekileyo phakathi konxibelelwano olusebenzayo nolwakhiwo ukusuka kuthungelwano lweeseli ukuya kwinethiwekhi elilawulayo kunye nenani leempazamo ngexesha lemeko engalunganga yomsebenzi we-Stroop kuzo zombini i-IGD kunye nezifundo zolawulo.
Iziphumo zethu ziphakamise ukuba ulawulo lwengqondo olungafanelekanga kulutsha lwe-IGD kunokwenzeka ukuba luxolelaniswe nonxibelelwano olungaqhelekanga kunye nokunxibelelana ngobume phakathi konxibelelwano lobuchwephesha bengqondo.
