Article Synopsis
- The brain determines limb positions by processing sensory information from mechanoreceptors, but this information can be noisy, leading to probabilistic processing based on prior beliefs about arm posture, utilizing Bayes' rule.
- A computational model combining a probabilistic kinematic chain with Gaussian noise was created to analyze errors in a VR posture matching task, where participants had to align their unseen arm to a target posture.
- The results revealed that a Bayesian model with Gaussian priors explained participants' response biases and variations more effectively than a uniform prior model, indicating unique biases in arm posture perception linked to individual differences.
