Kuyinto a feat ezingavamile for a meme ukukhasa out of the imbaxambaxa of internet amasiko kanye singene ngiqaphele abantu kwansuku zonke. Ikakhulukazi uma kwenzeka ngokushesha njengoba 'ingubo "wenza.

Phakathi ngoLwesine ebusuku nangoLwesihlanu ekuseni, ingubo lakhula ovela post Tumblr by i umculi Irish to buyinto omhlaba kanye isihloko mpikiswano embulungeni yonke.

The crux of the umbuzo dress, futhi mhlawumbe ukwedluliswa yayo, silula: iyona frock white negolide, noma blue and black?

The mkhuba kungaba umphumela illusion elula optical, i emagama, noma kungaba eziyinkimbinkimbi. Kungakhathaliseki ukuthi iyini imbangela, kungcono isithombe ngisho abacwaningi ukuqonda ukuthi ningavumelana.

"Ngakho kakhulu ngombono wethu futhi ezindlebeni kunembile ngempela,"Kusho Howard C Hughes, ngubani iphenya mechanisms okuqonda at uMnyango Dartmouth College sika sciences ngokomqondo kanye nobuchopho. "Uma bekungenjalo, sasingakwazi ukuhamba ngomnyango, futhi thina azinakukwazi ukugijima 50 amagceke ukunqaka ibhola fly in field centre. "

Kafushane, ungenaso crazy: iningi lokho okubonayo yilokho abanye abantu babone. Kodwa Hughes usikhumbuza ukuthi izinto "sibona" ​​akudingeki izimfanelo ayisisekelo sibona, ikakhulukazi uma sisebenzela ngolwazi limited, ezifana a grainy, photo ezimbili-ntathu.

Lezo zithombe Abantu ababefika babedla amakhasi up idatha eqoqwe amehlo ethu futhi ihlanganiswe by izingqondo zethu, eyakhiwa ngokusebenzisa eyinkimbinkimbi izinqubo begazi futhi ngokwengqondo.

"Lokho kudala, Ngiyacabanga, umuzwa wokuthi … nje sibona yini laphaya,"Uthe. "Kodwa sinawo ukwakha ukuthi - ubuchopho has ukwakha ukuthi - futhi abantu kufanele uqaphele ngendlela eziwubala udinga amehlo ukubona, kodwa udinga ubuchopho bona, futhi ukuze ukubona kuba into elisuselwa. "

The baxakekile dress igxile umbala, a wokuthi akukhona "wangempela" per se. Okuhlangenwe nakho umbala umbono ubude imisebe ebonakalayo ukukhanya ayeveza kusukela ebusweni, esichazwa njengenye yezinto imibala emithathu primary by the eye womuntu.

Ngokwesibonelo, lokho esikubonayo ngokuthi "red,"Akuyona imfanelo eziwumgogodla bento. Kunalokho, kungcono ukubona abantu 'ngokuphawulekayo homogenous of ukukhanya babonakalisa. Futhi kukhona inala izilwane ukuzwa umbala okuningi kakhulu ehlukile kunabantu. The zamehlo of mantis nezimfanzi, ngokwesibonelo, babe 12 umbala ezenza kuqhathaniswa abantu 'abathathu.

Futhi ngenkathi mbuzo ungase uzwakale ayibalulekile, abaningi baye bathola ukuthi isithombe uyisibonelo ethakazelisayo wetintfo of biology human and ukubona - constructs ezakha ezinye emasimini watadisha kakhulu ubuchopho science.

"Asikho isidingo sokucabanga ukuthi yonke imininingwane inqubo Amazing ukuthi akekho ngempela, oqonda ngokugcwele akanawo ukungefani kwabantu ngabanye,"Kusho Hughes. "Manje, indlela lokhu image ayenzile umsebenzi onjalo amazing yokwenza ukuthi othatha ezisobala - I Angiqiniseki. Kodwa ngicabanga ukuthi it sikhiphe ukushisa kangaka phakathi abantu abaningi of sicabange nje sibona yini laphaya. "

Hughes uthe subject ziyotholakala kuncike ucwaningo more, futhi Kucatshangelwa ukuthi lo mkhuba blue-white kungaba umphumela yini evela trichromats anomalous (Abantu abenza kunemibono ukuhluka of imibala primary babe) to a (nzima kakhulu) Goal illusion optical, ngezinye izikhathi esibizwa i emagama.

Noma ubani oye wazama ukutjhugulula orientation of convex and ngilugweda tindilinga, noma a ngalé ojikeleza kuyodingeka umqondo ezinye izithombe ezinjalo kunzima kanjani flip, noma "disambiguate".

Omunye umcwaningi ukubona. Robert Fendrich, utshele Hughes wabona ingubo njengoba igolide-white ngoLwesine kusihlwa, futhi blue-black ngoLwesihlanu ekuseni, omunye okubonakala bayingcosana abantu bakwazi reorient isithombe. Fendrich kuyinto isazi sokuvakasha Dartmouth College, futhi emnyangweni ngokwengqondo nesayensi ubuchopho.

At the Whitney Laboratory for Perception and Action at University of California Berkeley, David Whitney uthe ukusebenza isithombe ilula - kungcono an emagama of NEKUHLOLA.

"Wena ukuphetha ukukhanya ukushaya dress ngqo, Mina ukuphetha ngokuthi ukukhanya uvela ngemuva dress,"Kusho Whitney. "It yangempela umehluko ngempela elula, futhi kungcono emagama ngempela elula. "

"Kuyinto an illusion,"Kusho Whitney. "Kodwa konke an illusion."
