Final answer:
Learned reflexes are complex motor skills developed through practice and repetition, like driving, as opposed to innate reflexes that we are born with. They involve the cerebellum in the brain and become automatic over time.
Step-by-step explanation:
The reflexes being referred to are learned reflexes, which are complex motor skills that result from practice and repetition, such as driving skills. Unlike innate reflexes like the knee-j'rk response, learned reflexes develop over time as we adapt to our environment through experiences and learning. For instance, when you first begin to drive a car, it requires focused attention and effort to learn how to start the vehicle, brake, or handle a turn. Over time, these actions become automatic as the motor skills get encoded in the brain. This is a form of procedural learning, where the cerebellum plays a key role in refining these skills so they become second nature, allowing for more complex movements and responses.
