Brain teasers provide a mental workout that engages your cognitive faculties and challenges your thinking and problem-solving skills. They take the form of puzzles, riddles, optical illusions, and lateral thinking exercises. One viral optical illusion image on the internet features black and white stripes that transform into a speaker with vibration when scrolled. Another illusion hides images of a cat and moose, testing observers' vision. These brainteasers are based on the lateralization of cognitive ability, with individuals more inclined to recognize a specific animal based on their brain's lateralization.
Optical illusions use tricks to fool our eyes and brains. A picture of a girl's living room has a hidden pretzel, camouflaged with the wall cover. Spotting the pretzel is challenging in the packed image filled with paintings on the wall. Only 2% of people can find it. Optical illusions are a fun way to test your vision and give your brain a workout.
