This optical illusion puzzle challenges observation skills by hiding an odd number among similar digits. Backed by visual perception science, the puzzle explains how the brain interprets patterns and ...

The field of visual perception and material recognition examines how the human visual system deciphers the physical properties of objects—from their texture and gloss to subtle variations in surface ...

A study of mice starts to unravel how the brain gets tricked by this kind of optical illusion, and it gives clues about how visual perception works. When you purchase through links on our site, we may ...

An illusion is when we see and perceive an object that doesn't match the sensory input that reaches our eyes. In the case of the image below, the sensory input is four Pac Man–like black figures. But ...

Ensemble perception and visual averaging refer to the remarkable capacity of the human visual system to extract statistical summaries from groups of objects. By pooling similar features – such as ...

How optical illusions work has been long-debated among scientists and philosophers, who wonder whether these illusions stem from neural processing in the eye or involve higher-level cognitive ...

Sounds can alter the way the brain interprets what it sees. This is the key finding of a new study by SISSA researchers in Trieste, published in PLOS Computational Biology. The research shows that, ...

Experimental design (a) and results for the space experiment (b) and the ground-based control experiments (c & d). BMIE: the normalized BM inversion effect; BMUpr & BMInv: task performances for the ...

People rarely notice how their eyes shape their sense of the world, yet new research shows just how powerful this effect can be. A study from Ohio researchers reveals that even small changes in the ...
