Final answer:
Complex reflexes, like driving skills, are developed through practice and repetition, unlike newborn reflexes such as the sucking reflex which are automatic and innate. As individuals learn new skills, they strengthen neural pathways, particularly in the cerebellum, allowing these skills to become automatic.
Step-by-step explanation:
Reflexes are complex motor responses that result from practice and repetition. An example of a reflex that occurs in human development is the sucking reflex, which is present at birth and is an automatic response to the stimulation of the mouth area. This reflex is crucial for a newborn's nourishment and survival. Reflexes like the sucking reflex are part of a set of newborn reflexes, which are inborn responses that all healthy babies are born with. As individuals grow and learn, they start to develop other types of reflexes through repeated practice, like the motor skills necessary for driving a car, which eventually become automatic.
Reflex actions such as the knee-je_rk reflex are examples of innate behaviors. These occur without conscious thought and are rapid responses to stimuli. However, when we talk about skills developed from practice like driving or playing sports, these are acquired over time and through experience, demonstrating the process of learning and strengthening neural pathways, specifically engaging the cerebellum, which is integral for coordinating and refining motor skills.
