Divers who are excessively nervous are most likely to make simple mistakes due to the impact that anxiety and stress can have on cognitive function and task performance. When a diver feels overly anxious, their focus tends to narrow, which can lead to a reduced ability to process information effectively. This heightened state of nervousness can impair their judgment, attention to safety procedures, and execution of basic diving skills.

In a high-stakes environment like diving, where attentiveness and calmness are crucial for safety and efficiency, excessive nervousness can easily lead to oversight of critical details or mismanagement of equipment. Consequently, simple tasks may be overlooked or executed incorrectly, increasing the risk of accidents underwater. Therefore, managing anxiety and maintaining composure is vital for ensuring safe diving practices.
