Ngaba Izinja Ziyayibona Imibala?

Mhlawumbi omnye wemibuzo ebuzwa rhoqo malunga nombono wenja kukuba ingaba ubona imibala. Impendulo elula, eyokuba izinja zi-colorblind, zichazwe gwenxa ngabantu njengentsingiselo yokuba izinja aziboni mbala, kodwa ziimithunzi ezingwevu kuphela. Ayilunganga. Izinja ziyayibona imibala, kodwa imibala eziyibonayo ayityebanga okanye ayifani naleyo ibonwa ngabantu.

Amehlo abantu kunye nezinja anezinto ezizodwa ezibambe iiseli ezibizwa ngokuba ziicones eziphendula umbala. Izinja zineekhowuni ezimbalwa kunabantu, nto leyo ebonisa ukuba umbala wabo awuyi kuba sisityebi okanye ube namandla njengathi. Nangona kunjalo, inkohliso yokubona umbala ayisiyo nje ukuba neecones, kodwa ineentlobo ngeentlobo zeekhoni, nganye nganye ityhilwe kwimilinganiselo eyahlukeneyo yokukhanya. Abantu baneentlobo ezintathu zeekhoni kunye nomsebenzi odibeneyo wokunika abantu uluhlu olupheleleyo lombono wombala.

Ezona ntlobo zixhaphakileyo zobumfama bomntu buza ngenxa yokuba umntu elahlekile kolunye lweendidi ezintathu zeekhoni. Ngama-cones amabini kuphela, umntu ngamnye usenokubona imibala, kodwa uninzi luncinci kunomntu onombono oqhelekileyo wombala. Le yimeko yezinja ezineentlobo ezimbini kuphela zeekhoni.

UJay Neitz kwiYunivesithi yaseCalifornia, eSanta Barbara, wavavanya umbono wombala wezinja. Kwezilingo ezininzi zovavanyo, izinja zaboniswa ukukhanya kweepaneli ezintathu zilandelelana, iiphaneli ezimbini zazinombala ofanayo, ngelixa owesithathu wahlukile. Umsebenzi wezinja yayikukufumana enye eyahlukileyo kwaye ucofe loo phaneli. Ukuba inja ichanekile, wavuzwa ngokunyanga okwaziswa yikhompyuter kwindebe engezantsi kwepaneli.

UNeitz uqinisekisile ukuba izinja ziyayibona imibala, kodwa imibala emininzi kunabantu abaqhelekileyo. Endaweni yokubona umnyama njenge-violet, luhlaza okwesibhakabhaka, luhlaza-luhlaza, luhlaza, tyheli, orenji kunye nobomvu, izinja ziya kuyibona njengombala oluhlaza okwesibhakabhaka, oluhlaza okwesibhakabhaka, ongwevu, omthubi okhanyayo, omnyama otyheli (uhlobo oluntsundu), nobumnyama kakhulu ngwevu. Izinja zibona imibala yehlabathi njengombala otyheli, oluhlaza okwesibhakabhaka, kunye nokungwevu. Babona imibala eluhlaza, emthubi, kunye no-orenji ngombala otyheli, kwaye babona imisonto eluhlaza okwesibhakabhaka noluhlaza okwesibhakabhaka njengombala oluhlaza okwesibhakabhaka. Luhlaza-luhlaza kubonwa kungwevu. Uyabona ukuba injani imbonakalo yabantu kunye nezinja ezingezantsi.

Enye into ehlekisayo okanye engaqhelekanga kukuba imibala ethandwa kakhulu kwimidlalo yeenja namhlanje ibomvu okanye ukhuseleko iorenji (umbala o-orenji oqaqambileyo obomvu kwiikhowuni zezithuthi okanye iivesti zokhuseleko). Nangona kunjalo ebomvu kunzima izinja ukubona. Ingabonakala njengombala omdaka ngombala omnyama kakhulu okanye mhlawumbi umnyama. Oku kuthetha ukuba inja yokudlala ebomvu ebonakalayo ebonakalayo kuwe kunokuba nzima ukuba inja yakho ibone. Oko kuthetha ukuba xa inguqulelo yesilwanyana sasekhaya iLassie ibaleka idlula ngqo kwinto yokudlala oyiphosileyo isenokungabi neenkani okanye isisidenge. Isenokuba yimpazamo yakho ngokukhetha into yokudlala enombala ekunzima ukuyicalula kwingca eluhlaza yengca yakho.

Oko kusishiya nombuzo wokuba ingaba izinja zisebenzisa ubuchule bokubona umbala abanazo na. Ngakumbi malunga nokucofa apha.
