The Delboeuf Illusion: Exploring Perception Through Delboeuf’s Figures

Introduction The Delboeuf illusion, named after the Belgian philosopher and psychologist Joseph Delboeuf, is a fascinating optical illusion that highlights the complexities of human perception. It occurs when two circles of the same size are presented in varying contexts, leading to a misjudgment of their relative sizes. The purpose of this report is to explore the mechanisms behind the Delboeuf illusion, its implications for our understanding of perception, and its significance in broader psychological and cognitive studies. By delving into the empirical evidence and theoretical frameworks that underpin this phenomenon, we can gain insights into how visual information is processed and the inherent biases that influence our perception of reality.

The Delboeuf Illusion Explained The Delboeuf illusion is characterized by two concentric circles—one circle is surrounded by a larger circle while the other is enclosed by a smaller one. Despite both inner circles being identical in size, the inner circle surrounded by the larger outer circle appears smaller, while the one enclosed by the smaller circle seems larger. This illusion can be attributed to the way the human brain interprets visual stimuli, emphasizing the importance of contextual information in perception. One explanation for
