IINKCUKACHA: Isifundo esibonisa ukuhlala (ukuncipha kwempendulo ye-dopamine) kwimo yesini efanayo (ifilimu), kunye nokonyuka kokuvuseleleka ngokwesondo (ukwanda kwe-dopamine) xa kutyhilwa kwinoveli yesini. Uphononongo luye lwalinganisa impendulo eyoyikisayo, eyonyusa ukujonga ngakunye (baye bangena kancinci) Lo ngumzekelo wempembelelo yeCoolidge emsebenzini-ngakumbi i-dopamine xa iboniswa inoveli enokwenzeka. Inoveli yile nto yenza i-intanethi yahluke kwi-porn yexesha elidlulileyo.

Abstract
Ukumodareyithwa kwempendulo yokuqala kwakusetyenziswa ukuvavanya ukuqhubekeka ngokweemvakalelo kukhuthazo lwesini kuzo zonke iimvavanyo kwiseshini. I-eyeblink Startle yaphakanyiswa yiprobe (kuqhuma ingxolo enkulu emhlophe) yenziwa rhoqo ngelixa amadoda ebejonge icandelo leefilimu ezingaqhelekanga. Ukuphinda-phindwa kokuboniswa kwecandelo lefilimu kukhokelele ekuncipheni okuqhubela phambili kwezesondo. Ukwenza into yokuvuselela ngokwesondo kwakuhambisana kunye nokuncitshiswa kwezilingo ngokokude amadoda azive ebambekile xa ujonga amandla enyusa kunye nokunyuka kwezilingo kubungakanani benkqubela phambili yeliso. Ukutshintsha indawo yokhuthazo oluvuselelweyo yinkuthazo yovumo lwendalo eyonyukayo ekuvuseleleni ngokwesini kunye nokumiliselwa komzimba kunye nokuqalisa okunciphisayo (isiphumo sobunyani), Ngelixa isitya sokutya sabonakala kuwo omathathu la manyathelo okuphendula xa iphinda iveliswe kwakhona. Le pateni yeziphumo ibonakalisa ukuba xa usenza impapasho ephindaphindiweyo ivuselela inkanuko yesini ayisiva nje njengokuvusa ulwabelana ngesondo kodwa kunye nokubanomdla ongaphantsi kunye nokutsala. Umbuzo wokuba ingaba indawo yokuhlala yokwabelana ngesondo ivuselelwa ngotshintsho ekuqwalaselweni ingqalelo kunye nokusebenza ngokuhambelana ngaphezulu kwezilingo kuyaxoxwa, njengakwiimeko zeklinikhi apho iliso lokwenza liso lisohlo lingasetyenziswa ekufundeni iinkalo zomsebenzi wesondo.
