What do you see: Quick brain teaser to share this weekend

What do you see?

Ambiguous Illusion

Take a good look…you should be able to per­ceive two dif­fer­ent images (but prob­a­bly not at the same time).

What’s going on:
This image is an exam­ple of an ambigu­ous illu­sion — a pic­ture or object that requires per­cep­tu­al switch­ing between the alter­na­tive inter­pre­ta­tions of fig­ure and ground. And although you may be able to switch back and forth to see one image or the oth­er, your eyes will not let you see both at the same time.

Our visu­al per­cep­tion is cre­at­ed by our brain’s inter­pre­ta­tion in the cere­bral cor­tex of visu­al infor­ma­tion enter­ing through the visu­al path­way. Our minds get active­ly involved in inter­pret­ing the per­cep­tu­al input, rather than pas­sive­ly, objec­tive­ly record­ing it.

Please remem­ber that next time your have a strong dis­agree­ment with some­one: You may both be fac­ing the same exact real­i­ty but “see­ing” it in dif­fer­ent ways!

You can see an Indi­an Chief (fac­ing left) or an Eski­mo walk­ing towards the right.
