Ukukhumbula izikhathi ezingcono kuthuthukisa ukusebenza kwengqondo kubantu ababencishwe amathuba, ngokusho kocwaningo olusha. Ngokuqondile, ithuthukisa i-IQ. Lokhu okutholakele kuphakamisa nokuthi ukwenza ngcono ukuzethemba kubantu ababencishwe amathuba kuyabasiza benze izinqumo ezinhle futhi kubakhuthaza ukuthi baphendukele emisebenzini yezenhlalakahle ukuze bathole usizo.
"Lolu cwaningo lukhombisa ukuthi ukuzimela (ukuqinisa ngokwengqondo amandla omuntu) kuthuthukisa ukusebenza kwengqondo nokuziphatha kwabantu abampofu"kusho umlobi-mbhali ocwaningayo kanye noprofesa wase-University of British Columbia uJiaying Zhao. Ucwaningo luzoshicilelwa kule nyanga ku- Ijenali yeSayensi Yezengqondo.
Ukuhlolwa okuyinhloko kwenziwa ekhishini lesobho laseNew Jersey iminyaka emibili. Babalelwa ku-150 ababambiqhaza ababambe iqhaza ocwaningweni.
Uma kuqhathaniswa neqembu elilawulayo, ababambiqhaza, abangahleliwe, abenza izivivinyo zokuziqinisa, njengokulandisa umzuzu owedlule wokuziqhenya noma wempumelelo, bakhuphule i-IQ yabo ngamaphuzu ayi-10. Babenamathuba amaningi okufuna imininingwane mayelana nezinsizakalo zosizo kuhulumeni wasekhaya.
Ucwaningo lwangaphambilini lukhombisile ukuthi ukuzimela ngokwakho kuthuthukisa izikolo zokuhlolwa kwelinye iqembu elibekelwe eceleni: abafundi base-Afrika baseMelika. Lesi yisifundo sokuqala ukusebenzisa amasu okuziqinisa ngomlomo kubantu abaphila ngobumpofu.
Ucwaningo lunemithelela ebalulekile yenqubomgomo, kufaka phakathi amandla okwenza ngcono izinhlelo zosizo: ukunakekelwa kwezempilo, izitembu zokudla, nokubuyiselwa kwemali yentela.
Abaphenyi bakholelwa ukuthi ukuzishaya isifuba kunciphisa ukucwaswa kwendlala.
Lolu cwaningo lwakha phezu kocwaningo lwangaphambilini oluthola ukuthi ubumpofu budla amandla engqondo amaningi kangangoba buqeda amandla engqondo alabo abathintekayo njengoba bengenaso isikhathi sokugxila kwezinye izinto zempilo. Kusele "umkhawulokudonsa wengqondo" omncane osele ukuqeqeshwa, ukuphathwa kwesikhathi, izinhlelo zosizo kwezemfundo nezinye izinyathelo ezingasiza ekuqedeni imijikelezo yobuphofu. Fuente
