Quick brain teaser to workout your frontal lobes: Can you read this face?


Dr. Elkhonon Gold­berg, in dis­cussing the human brain’s frontal lobes in his excel­lent book The Wis­dom Para­dox, high­lights that “exec­u­tive intel­li­gence” includes the abil­i­ty to “pen­e­trate oth­er people’s minds, and that starts with an inter­est in oth­er people’s minds.”

And, what is a good win­dow to “pen­e­trate oth­er people’s minds” and iden­ti­fy oth­er peo­ple’s emo­tions? Read the rest of this entry »

Ambiguous Visual Illusion

What do you see?

Do you see a series of black shapes on a white back­ground, or do you see a white word on black back­ground? Try to see both, one at a time 🙂

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. Our visu­al sys­tem sim­pli­fies visu­al scenes into a fore­ground fig­ure that we focus on and a ground which is every­thing else and forms the back­ground. And although you may be able to switch the fig­ure and ground back and forth to see one image or the oth­er, your eyes will not let you see both images 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.

The word in white let­ters is LIFT.
