Final answer:
Walking requires the sensory-perceptual skills of tactile sensation and balance, involving the vestibular sense for equilibrium and somatosensation for contact feedback.
Step-by-step explanation:
The sensory-perceptual skills required for walking are tactile sensation and balance. These skills fall under the category of somatosensation, which is part of the general senses involving the entire body. The sense of balance, helped by the vestibular sense, is crucial for maintaining equilibrium during movement.
Moreover, tactile sensations provide feedback from the contact between the body and the surfaces we navigate, thus aiding in the safe and effective placement of feet while walking.
