A person using a prosthetic arm with haptic feedback struggles to grasp delicate objects without crushing them. Which failure mode involving mechanoreceptor feedback is most likely?

💡 Explanation

The prosthetic user crushes objects because lateral inhibition sharpens tactile sensation, suppressing weak pressure signals and exaggerating strong ones. Therefore, they overestimate grip force. This occurs because lateral inhibition enhances contrast, rather than accurately relaying gradual pressure changes.
