That is one reason counting puzzles can be deceptive.
A partially obscured tomato, an unusual shape, or two objects positioned closely together may be interpreted incorrectly during the first glance.
The Importance of Selective Attention
Psychologists have long studied selective attention, or our ability to focus on certain information while filtering out other details.
Imagine searching for your car in a crowded parking lot. You may concentrate so heavily on finding its color and shape that you barely notice other vehicles around you.
Visual puzzles take advantage of similar tendencies.
When someone tells you to “count the tomatoes,” your attention immediately focuses on recognizable tomato shapes. If one object does not perfectly match the expected pattern, your brain may initially overlook it.
This does not mean your eyesight is poor. It demonstrates how efficiently the brain prioritizes information.
Why People Get Different Answers
Another interesting aspect of visual puzzles is how confidently people can disagree.
