Have you ever felt that the size of your hand sometimes doesn't seem accurate?In fact, the perception of opponents in the brain is not entirely accurate.
Researchers at the University of York have discovered that the position of the hand affects the brain's estimation of the size of the hand
In this study, the researchers asked participants to extend their arms and then used a special device to place circles of different sizes on the back of the hand, allowing the participants to perceive the size of the circles on the back of the hand. It was found that the brain's perception and visualization of the back of the hand was accurate when the arm was extended;
But when the arm is bent, the brain's perception and visualization of the back of the hand changes with the position of the hand, that is, the brain incorrectly perceives the size of the circle on the back of the hand. The authors of the study note that this phenomenon is important for understanding the brain's perceptual mechanisms.
Because the brain's perception of our body is achieved through sight and touch, and tactile information is provided by our hands.
Therefore, the results of this study suggest that our brains may be affected by body posture and position, leading to misjudgments of body perception.
What do you think of this study?We still don't know what the sensory mechanism of the brain's opponents is.
But the results of this study give us a deeper understanding of how we perceive our bodies. If you are interested in this topic, please leave a message in the comment area and share your thoughts!
