Optik ill\u00fczyonlar, toplumsal medyan\u0131n en sevdi\u011fi i\u00e7erik tiplerinden biri. Bireyleri etkile\u015fime ge\u00e7iren ve k\u0131sa m\u00fcddette gelen onlarca farkl\u0131 yan\u0131tla viral olan bu \u00e7e\u015fit ill\u00fczyon sorular\u0131n\u0131n her birinin gerisinde asl\u0131nda epeyce bilimsel yan\u0131tlar yat\u0131yor. Lakin bu bilimsel ger\u00e7ekler her vakit tek bir ger\u00e7ek yan\u0131t olmas\u0131na y\u00f6nelik de\u011fil, kimi vakit da neden bir s\u00fcr\u00fc farkl\u0131 kar\u015f\u0131l\u0131k oldu\u011funu bize a\u00e7\u0131kl\u0131yor.<\/p>\n

Ge\u00e7ti\u011fimiz g\u00fcnlerde Twitter’da ortaya \u00e7\u0131kan yeni bir optik ill\u00fczyon sorusu, bu durum i\u00e7in kusursuz bir \u00f6rnek. Kelam konusu payla\u015f\u0131mda birbirine epey yak\u0131n renk tonlar\u0131ndan olu\u015fan bir g\u00f6rsel yer al\u0131yor ve sorumuz epeyce kolay: ‘Bu foto\u011frafta ka\u00e7 renk g\u00f6r\u00fcyorsunuz?’<\/p>\n

3 renk g\u00f6ren de var, 17 renk g\u00f6rende:<\/b><\/p>\n

Payla\u015f\u0131m\u0131 g\u00f6remiyorsan\u0131z buraya t\u0131klayabilirsiniz.<\/p>\n

Nat\u00fcrel ki varsay\u0131m edece\u011finiz \u00fczere payla\u015f\u0131m\u0131n viral olmas\u0131 sonras\u0131 soruya binlerce yan\u0131t geldi. Gelen yan\u0131tlar ise birka\u00e7 ortak yan\u0131t \u00fczerinde \u015fekillendi. B\u00fcy\u00fck \u00e7o\u011funluk 3, 11, 17 yan\u0131tlar\u0131n\u0131 verirken say\u0131y\u0131 20’ye \u00e7\u0131karanlar ya da tek renk g\u00f6rd\u00fc\u011f\u00fcn\u00fc s\u00f6yleyenler de vard\u0131.<\/p>\n

Pekala yan\u0131tlar ortas\u0131nda bu kadar fark olmas\u0131n\u0131n sebebi ne? Asl\u0131nda bu sorunun tek bir kar\u015f\u0131l\u0131\u011f\u0131 yok zira g\u00f6zlerimizin renkleri farkl\u0131 d\u00fczeylerde alg\u0131lamas\u0131 tek bir sebeple olmuyor. Ya\u015fa, cinsiyete, renklere bakt\u0131\u011f\u0131m\u0131z ekrana, ortamdaki \u0131\u015f\u0131\u011fa ve hatta retinalar\u0131m\u0131z\u0131n yap\u0131s\u0131na nazaran bile bu yan\u0131tlar farkl\u0131l\u0131k g\u00f6sterebilir. <\/p>\n

Beynimizin daha fazla ve daha g\u00fczel alg\u0131layabilmek i\u00e7in oynad\u0131\u011f\u0131 bir oyun:<\/b><\/p>\n

<\/p>\n

Lakin bu durumu t\u00fcm bunlar\u0131n d\u0131\u015f\u0131nda genel bir fizyolojik ill\u00fczyonla a\u00e7\u0131klamak da m\u00fcmk\u00fcn; lateral inhibisyon (yanal inhibisyon, yanal engelleme). Buna nazaran n\u00f6ronlar, \u00f6b\u00fcr n\u00f6ronlar taraf\u0131ndan bask\u0131lan\u0131r; uyar\u0131lm\u0131\u015f n\u00f6ronlar, yak\u0131ndaki n\u00f6ronlar\u0131n aktivitesini mahzurlar. Bu da duyu alg\u0131m\u0131z\u0131 sertle\u015ftirmeye yard\u0131mc\u0131 olur.<\/p>\n

\u00dcnl\u00fc fizik\u00e7i Ernst Mach’un geli\u015ftirdi\u011fi ve March bantlar\u0131 olarak da an\u0131lan bu duruma nazaran, imgede kontrast\u0131 art\u0131ran da tam olarak budur. Daha a\u00e7\u0131klay\u0131c\u0131 olmak gerekirse \u015f\u00f6yle d\u00fc\u015f\u00fcnelim; birbirine \u00e7ok benzeyen iki farkl\u0131 renge bakarken beynimize iki hudut h\u00fccresinden birebir anda emsal bir sinyal geldi\u011finde, beynimiz bunu birebir olarak alg\u0131lamaya yatk\u0131n.<\/p>\n

Ama yeniden beynimiz, bu cins ufak yanl\u0131\u015flara d\u00fc\u015fmemek ve \u00e7ok daha fazla misal rengi alg\u0131layabilmek i\u00e7in savunmas\u0131n\u0131 da geli\u015ftirmi\u015f durumda, bu da Ernst Mach’\u0131n a\u00e7\u0131klad\u0131\u011f\u0131 lateral inhibisyon ile oluyor. Birbirine yak\u0131n renklere dair gelen sinyaller bu sayede farkl\u0131 ayr\u0131 de\u011ferlendirilip birebir anda \u00e7ok daha fazla rengi g\u00f6rmemize imkan sa\u011fl\u0131yor.<\/p>\n
