The four subtasks of riding include social, emotional, physical, and mental- perceptual. The mental-perceptual subtask involves cognitive and perceptual processes related to observing the environment, making decisions, spatial awareness, and selecting appropriate actions during riding. This subtask complements the social skills (interacting with others and following traffic rules), emotional skills (managing feelings such as fear or stress), and physical skills (coordination, balance, and energy exertion) required for safe and effective riding.
