Final answer:
Pain tolerance is the maximum level of pain a person can endure, not the point at which pain is first felt, which is known as the pain threshold. The statement is therefore false.
Step-by-step explanation:
The statement that a child's pain tolerance refers to the point at which the child first senses pain is false. Pain tolerance is actually the maximum level of pain that a person can handle before it becomes unbearable, rather than the initial point at which pain is first perceived. This initial perception of pain is commonly referred to as pain threshold. Individuals with a rare genetic disorder known as congenital insensitivity to pain (or congenital analgesia) are unable to experience pain at all, despite being able to detect differences in temperature and pressure. Such individuals may suffer injuries without the protective response of pain due to a lack of pain receptors or a malfunction in their signaling pathways.
