Aceast\u0103 iluzie optic\u0103 e at\u00e2t de puternic\u0103, \u00eenc\u00e2t \u021bi-e greu s\u0103 \u00een\u021belegi cum func\u021bioneaz\u0103. Descifrezi misterul?<\/figcaption><\/figure>\n\n\n\n

Uneori, creierul nostru poate percepe anumite imagini \u00een mod gre\u0219it, adic\u0103 ceea ce vedem nu reflect\u0103 neap\u0103rat realitatea. Cele mai populare astfel de imagini sunt iluziile optice, care \u00eei pot p\u0103c\u0103li chiar \u015fi pe cei mai vigilen\u0163i dintre noi. Iat\u0103 un exemplu concret. <\/h3>\n\n\n\n

Imaginea de mai jos reprezint\u0103 o iluzie optic\u0103 ce se va juca nemilos cu mintea ta. La prima vedere par a fi mai multe culori combinate \u0219i destul de palide, \u00eens\u0103 dac\u0103 prive\u0219ti atent \u00een centrul ei timp de 20 de secunde, vei observa c\u0103 \u00eencet-\u00eencet, culorile vor disp\u0103rea \u0219i nu vei mai vedea dec\u00e2t alb.<\/p>\n\n\n\n

Este important s\u0103-\u021bi la\u0219i ochii s\u0103 se relaxeze \u0219i s\u0103 nu \u00eei mu\u021bi \u00een alt\u0103 parte a imaginii deoarece, \u00een momentul \u00een care \u021bi-ai pierdut concentrarea, culorile vor reveni imediat.<\/p>\n\n\n\n

\"Imagine\"<\/figure>\n\n\n\n

Probabil te \u00eentrebi cum este posibil ca ochii t\u0103i s\u0103 vad\u0103 culorile albe. Ei bine, este vorba despre efectul Troxler care a fost definit de c\u0103tre fizicianul suedez Ignaz Paul Vital Troxler. Mai exact, acest efect dezv\u0103luie cum te poate induce \u00een eroare uneori creierul t\u0103u.<\/p>\n\n\n\n

Ce este efectul Troxler<\/h2>\n\n\n\n

Troxler a observat acum 200 de ani c\u0103 anumite obiecte \u0219i culori \u00eencep s\u0103 dispar\u0103 din c\u00e2mpul lui vizual. Astfel, a emis o ipotez\u0103 care spune c\u0103 \u201eatunci c\u00e2nd ochii unei persoane r\u0103m\u00e2n concentra\u021bi pe un stimul neschimbabil pentru o perioad\u0103 lung\u0103 de timp, detaliile viziunii periferice a acesteia \u00eencep s\u0103 dispar\u0103”.<\/p>\n\n\n\n

\u00cen cazul detaliilor \u00eence\u021bo\u0219ate \u0219i cu contrast mic (precum \u00een imaginea cu culori pastelate), procesul de dispari\u021bie este chiar mai rapid. Acest lucru se \u00eent\u00e2mpl\u0103 datorit\u0103 capacit\u0103\u021bii creierului uman de a se adapta rapid la stimuli noi, conform oamenilor de \u0219tiin\u021b\u0103.<\/p>\n\n\n\n

Ca s\u0103 \u00een\u021belegi mai bine, g\u00e2nde\u0219te-te de exemplu la urm\u0103toarea situa\u021bie – \u00een momentul \u00een care \u00ee\u021bi pui pantalonii pe tine, sim\u021bi materialul pe piele. \u00cens\u0103, dup\u0103 c\u00e2teva secunde senza\u021bia dispare pentru c\u0103 nu mai e\u0219ti con\u0219tient de ea. Asta pentru c\u0103 neuronii t\u0103i s-au adaptat unui stimul neschimbabil, a\u0219a c\u0103 au ajuns s\u0103 \u00eel pun\u0103 \u00een categoria informa\u021biilor neimportante. Exact la fel se \u00eent\u00e2mpl\u0103 \u0219i \u00een cazul iluziei de mai sus.<\/p>\n\n\n\n
