Brain Teasers: Spot the Difference
Dr. Pascale Michelon recently shared with our readers which brain areas and cognitive functions are engaged as we solve the type of brain teaser known as Spot the Difference, where we have to find the differences between two versions of one image:
"1) You have to identify the objects that you see: this involves your occipital lobes (in red).
2) You have to analyzed the spatial relationships between the objects that you see: this involves your occipital and parietal lobes (in green).
3) You have to remember what you see in one picture and compare it to what you see in the other picture, that is you have to use your short-term memory: this involves your frontal (in blue) and parietal lobes.
4) You have to mark down the locations where you see a difference: this involves mostly your frontal lobes (for the movement)".
Ready! Set! Go!: how many differences can you spot, and which ones?

Strange enough during our cognitive development we learn to differentiated between images and things.. and we are taught to assign them names on basis of our imagination about those images..
i see 12.
13 differences
13 already...
Oh! 14!
I see 15
Aaargh! 15 and i STFU
SPOILER!
clock - curtain - hair - shirt - banana - cake - cookie - plant - lollypop - sock - dish - tongue - 2 little guys - mountains (paint) - 2 little hearts.
actually there are 415 differences. look at the major pixals on the left.
16 - look at the clock's pendulum
I don't see a difference between the cakes. But both shirt collars are slightly different.
Sean - Look at the bottom of the icing
You can spot all the differences by crossing your eyes and watching both images stereoscopically. Lulz.
You can also win at monopoly by sneaking extra hundreds. lulz indeed.
There is one difference.
The pot on top of the cabinet looks different.
The easiest way to solve these is to cross your eyes so you see three images. The central image will have "fluttery" elements where there is a difference. Then it is easy to list them.
16 differences, no squinting, no pixelating
I found 11.
I see 21 so far. I'm sending it on to my 9 yr old granddaughter to see if she finds more.
21!! where?
I found 17,going to ask my 11 yr old how many he see

Time magazine has a series of books with comparison photographs. I use them with my speech/cognitive clients all the time! Photos are easier than cartoon drawings, esp ones like this with color blending, etc.
I spotted 16. I am 70 going on 71.
I see 16, so far.
I see 15. Same ones as spdrsnake, except I can't see any difference in the pendulum.

I think you can debate what is actually a difference or maybe just a fainter bit of colour as each one does not have everything perfectly identical...
