Verified step by step guidance

1. Understand that psychological research on stress focuses on how stress affects cognitive processes such as attention, memory, and decision-making.
2. Recognize that high levels of stress can impair cognitive functioning, which means the brain's ability to process information and respond accurately is reduced.
3. Consider that impaired cognitive functioning under stress leads to mistakes or human errors because individuals may have difficulty concentrating or making sound judgments.
4. Evaluate the other options (lack of physical strength, environmental noise, genetic predisposition) and understand that while they may influence performance, they are not identified as the main cause of human error in the context of stress research.
5. Conclude that the main cause of human error according to psychological research on stress is the impairment of cognitive functioning due to high stress levels.
