What does sensory reweighting mean?

• A. Relying on vision exclusively
• B. Choosing which sense to rely on
• C. Increasing reliance on proprioception only
• D. Relying on vestibular input exclusively

Answer: (B)

Sensory reweighting is about the brain flexibly adjusting how much it relies on each sensory input—vision, proprioception, and vestibular cues—so balance is maintained even when some signals are unreliable. The best description is choosing which sense to lean on based on how trustworthy each input is in the moment. For example, on a foam surface proprioceptive input from the feet becomes less reliable, so the system upweights vision or vestibular information to keep posture stable. The other options imply relying exclusively on one sense, which isn’t how the system adapts to maintain balance.
