Final answer:
The general control theory does not specify an age at which self-control stops, but rather emphasizes that self-control is a skill that can be developed and improved throughout life.
Step-by-step explanation:
The general control theory does not state a specific age at which individuals no longer learn self-control. Rather, it suggests that self-control is a skill that can be developed and improved throughout one's lifetime. Research by Mischel and his colleagues found that self-control in early childhood is a predictor of success in various areas later in life, such as academic performance, peer relationships, and even marriage stability. However, this does not mean that individuals cannot continue to learn and improve their self-control skills in adulthood. Therefore, it is important to cultivate self-control abilities at any age as it can have long-lasting positive effects on various aspects of one's life.
