Stare at the central dot: the yellow dots will disappear. It's called motion-induced blindness and it may result from a tussle for supremacy between the left and right halves of our brain.

That’s interesting! Motion-induced blindness (MIB) isn't perfectly symmetrical for everyone, and your experience highlights how personal visual processing can be.
There are a few possible reasons why only two of the dots disappeared while the third remained: Visual Field Sensitivity: Your eyes and brain may have different sensitivities in different parts of your visual field. The bottom left area might not be as easily overridden by motion as the others. Each eye processes visual input differently, and slight imperfections or asymmetries in the brain's visual map could be responsible. Eye Dominance: If one of your eyes is dominant (which is true for most people), it may influence how peripheral objects appear to "disappear." The brain favors input from the dominant eye, which could explain why the lower left dot doesn’t vanish as easily. Peripheral Attention: Even though you're focusing on the center, your brain might be unconsciously more attentive to certain parts of your periphery, like the lower left, making it harder for the motion-induced blindness effect to kick in for that dot. Micro-saccades: Your eyes constantly make tiny, involuntary movements (called micro-saccades) even when you're trying to fixate on a central point. If these tiny movements differ slightly in how they affect the lower left part of your vision, that could keep the dot visible.
That popping in and out effect is actually a classic characteristic of motion-induced blindness! It happens because your brain is constantly trying to reconcile the conflicting information from stationary objects (the yellow dots) and the motion in your field of vision. As your brain tries to prioritize what it perceives as important, the dots may vanish, only to reappear moments later when your visual system “resets” or re-evaluates the scene. This fluctuation highlights how our perception is a dynamic process, not just a static reception of sensory data. It’s constantly filtering and interpreting information, sometimes even to the point of erasing things from awareness, then bringing them back as priorities shift. The longer you stare, the more likely this popping effect is to occur, since your brain is actively balancing different visual inputs. It's a fun (and slightly bizarre) insight into how the brain works!

I am for sure left eye dominant. That is fascinating and perhaps that gives the bottom left dot preferential treatment in my mind. Wild stuff.
