IMIBUZO: Ukutadisha kubonisa ukujwayela (ukwehla ukuphendula kwe-dopamine) kuzimo ezifanayo zocansi (ifilimu), kanye nokwanda kokuvusa ucansi (okwandayo kwe-dopamine) lapho kuvezwa inkuthazo yezocansi yenoveli. Ucwaningo luphinde lwalinganisa ukuphendula okwethusayo, okwenyusa ukubukwa ngakunye (bagxila kancane) Lesi yisibonelo somphumela weCoolidge emsebenzini - i-dopamine ethe xaxa lapho yethulwe ngenhloso entsha yezocansi. Inoveli yilokho okwenza i-porn ye-Intanethi ihluke kwezocansi zangesikhathi esedlule.

abstract
Ukushintshwa kokuphendula okumangazayo kusetshenziselwe ukuhlola ukucubungula okungokomzwelo kokukhuthaza ngocansi kuzo zonke izivivinyo ngaphakathi kweseshini. I-eyeblink startle yagqamiswa yi-probe (ukuqhuma komsindo omhlophe kakhulu) eyethulwa ngezikhathi ezithile ngenkathi amadoda ebuka ingxenye yamafilimu eyindida. Ukuphindaphindwa kokukhonjiswa kwengxenye yefilimu kuholele ekunciphiseni okuqhubekayo komusa wobulili. Ukwenziwa komkhuba wokuvuselela ezocansi kuhambisana nokuncishiswa kwezilingo ngezinga amadoda ayezizwa egxilwe ngalo lapho ebuka umfutho ongathandeki kanye nokwanda kwezilingo ngobukhulu bokusabela kokuqala kwamehlo. Ukushintsha isisusa esijwayelekile ngesikhuthazo senoveli esikhulayo ekuvuseleleni kwezocansi nokumunca nomphumela omncane (nomphumela ongemuva), ngenkathi i-dishabituation ibonakala kuzo zontathu izindlela zokuphendula lapho ukugqugquzelwa okujwayelekile kuphinde kwenziwa kabusha. Le ndlela yemiphumela ikhombisa ukuthi ngesethulo esiphindaphindayo isisusa esibi asitholakali njengento evusa inkanuko yezocansi kuphela kepha futhi siyathokozela futhi siyabamba. Umbuzo wokuthi indawo yokuhlala yecala lokuvuselela abanye ngokocansi iqondiswa izinguquko ekunakekelweni ngokubhekisisa nokuvumelanisa ngaphezu kwezilingo kuyaxoxwa, njengoba kunjalo nangezimo zokwelapha lapho i-eyeblink startle ingasetshenziswa khona ekutadisheni izici zokusebenzisa ucansi.
