Abstract

The article focuses on the discovery and investigation of the banana bisection illusion, a visual illusion occurring in natural environments where the side of a banana adjacent to the stem appears longer than it is, leading people to cut it shorter when attempting to bisect it. Experiments with both outline drawings and realistic 3D plastic bananas demonstrated the illusion, which was stronger when the stem was present but also occurred without it, suggesting that both the stem and the banana's curvature contribute to the effect. The findings challenge earlier claims that illusions only arise from artificial stimuli, showing that visual illusions can occur with natural, solid objects. This research highlights the presence of unnoticed illusions in everyday perception and supports their relevance for perceptual psychology.
