Research progress has been made on the role of genes and environmental factors in the processing of large and small illusions

Our perception of size is not a passive reflection of the physical size of the object, and is often affected by the background information of the space where the object is located

People's perception of size is not a passive reflection of the physical size of the object, and is often affected by the background information of the space where the object is located

Studies have found that some animals (including dolphins, fish, macaques, parrots and chicks only 4 days old) can also perceive the illusion of size like humans, which suggests that human perception of the illusion of size may be acquired through evolutionary means, namely It is hereditary

The study recruited 80 pairs of twins of the same sex (40 pairs of identical and fraternal), and recorded their brain activity while watching the Ebbinghaus illusion and the brain activity with their eyes closed 3 minutes before the experiment

This study quantified the role of genes and environmental factors in Ebbinghaus's illusion processing at the level of behavior and neural activity for the first time, suggesting that human size illusion processing will be affected by both genes and the environment, and the two act on different visual processing.
