abstract
Ucwaningo lwe-neuroimaging lwesintu lukhombisa ubukhona benethiwekhi eyodwa eyisisekelo yokulinganisa okuhle kwemivuzo, kufaka phakathi i-striatum ne-orbitofrontal cortex. Kodwa-ke, kunokucwaninga okuncane ekumeleleni kwe-neural yamanani wokuvuza wokuziphatha oshukumisayo wezocansi obonakalayo (i-VSS) kanye nendima yalezi zibalo ezilinganayo ekwakhiweni kwezimo ezihlobene zokulutha. Lapha, siphenya ukuthi i-neural reacaction ku-VSS ixhumeke kanjani ekuthandweni komuntu ngamunye kusetshenziswa i-imaging magnetic resonance imaging (fMRI) esebenzayo. Ngesikhathi sokuhlolwa kwe-fMRI, amadoda angama-72 abuka iziqeshana zefilimu ze-VSS ezahlukahlukene. Ukulinganisa maqondana nobudlova nokuvuseleleka kwezocansi kuqoqwe futhi kwasebenza njengamamojula we-parametric ekuhlaziyeni kwe-fMRI. Izindatshana zibuye zigcwalise nemibuzo ngezimpawu ezizibikayo zokusebenzisa kabi izithombe zobulili ezingcolile (PPU). Okokuqala, sithole ukuthi ukwenziwa kwe-neural maqondana neziqeshana ze-VSS ku-nucleus accumbens, i-caudate nucleus kanye ne-orbitof Pambal cortex kwahlotshaniswa kahle nokukalwa ngakunye kwe-VSS efanelekile kuzo zonke izifundo. Okwesibili, amandla wobudlelwano phakathi komsebenzi we-neural kanye nezilinganiso zokuvuselela ezocansi kwahlanganiswa kahle nezimpawu zokuzibika ze-PPU. Umphumela wokuqala uphakamisa ukuhlolwa okucacile kwe-VSS ngokuya ngokuthanda komuntu ngamunye kwizifunda zokuqashelwa komvuzo ezisunguliwe. Okwesibili, ukwahluka okuqinile kwe-neural ngokususelwa kokuthandwayo kwabahlanganyeli abanezimpawu ezengeziwe ze-PPU kukhombisa ukubaluleka okukhulayo kwe-VSS / preference fit kulaba bantu. Lokhu kuxhumana okwandisiwe phakathi kokuthanda komuntu kanye nomsebenzi we-neural kungasiza ukuthuthukiswa kwe-PPU ngokwanda kokubonisa kokuqina kwesisusa sokukhuthaza, ngaleyo ndlela kukhuthaze isisusa sokufuna futhi ukuphendula kulezi zinhloso ezithandwayo.
