Which of the following is an example of a cue that can assist in route learning?

Auditory cues, such as traffic sounds, play a significant role in route learning by providing information about the environment that can enhance spatial awareness and orientation. These sounds can give learners immediate feedback about their surroundings, helping them to identify important landmarks or hazards along a route. For example, the sound of traffic might indicate proximity to a busy street, allowing a person to navigate safely. Auditory cues engage multiple senses, which can aid memory retention and recognition, making the route learning process more effective and intuitive.

While the other choices involve different types of cues that can also assist in route learning, auditory cues directly relate to immediate environmental interaction, making them a critical component in the mobility process.
