Hazard perception is the ability to identify potential dangers in a situation, which is influenced by visual and auditory perception, situational and life experience, and cognitive processes. Well-developed skills can prevent accidents, but deficiencies can lead to risks during learning curves. Training programs can help identify and improve hazard recognition skills. Vigilance can also compensate for a lack of perception.
Danger perception is a complex human cognitive ability that allows a person to identify a potentially dangerous situation. Well-developed risk perception skills enable people involved in activities such as driving to identify hazards in time to take appropriate preventive measures. Instinctively slowing down when approaching a group of children playing on the road is a good practical example of this ability. Unfortunately, these skills are dependent on the individual’s visual and auditory perceptual abilities and are largely honed by experience, leading to increased risk during learning curves. They are also highly individualistic characteristics and are not equally developed in all people.
A person’s ability to assess a situation as it unfolds and quickly identify potential hazards in time to avoid them is known as hazard perception. This ability is a product of auditory and visual perception skills, situational and life experience, and complex cognitive processes such as attention to detail and concentration. Accumulation of experience both in terms of situational exposure in a specific activity and life experience in general is difficult to gain over long periods of time and unfortunately goes hand in hand with elevated risks early in any learning curve. . Both areas of perceptual ability and combined experience play a critical role in the perception of danger as the driving example mentioned above demonstrates.
When approaching playing children, the driver assimilates both visual and auditory information, the extent of which will depend on the individual’s ability in these areas of perception along with their level of concentration at the time. Unfortunately, if the driver does not see and hear the children in time to react proactively, any risk avoidance action will accumulate in the split second it takes for one of the children to chase a ball onto the road. This type of situation all too often leads to tragic loss of life and emphasizes the importance of identifying any type of impaired perception early.
When the potential danger posed by children’s activities has been visually identified, the situational experience should alert the driver to the fact that it will be difficult to avoid a collision at higher speeds, so he or she will slow down on approach. Furthermore, life experience may have taught the driver to take into account the fact that children, while engrossed in their play, are unlikely to pay enough attention to traffic to avoid causing potential danger. These visual cues and both insights combined with vigilance and attention to detail should cause the driver to slow down and possibly pull away from the curb while passing children. A driver who misses the warning flags and knocks over one of the children is not necessarily a bad driver, technically, but exhibits a dangerous deficiency in hazard identification skills.
These abilities are highly individualistic and do not develop equally in all individuals. Fortunately, it is possible, in many cases, to identify a lack of hazard recognition skills, allowing the individual to focus on improving them. Training programs for many hazardous activities include comprehensive hazard perception tests that will give early warning of any deficiencies in individuals’ inherent skills. These tests are included in many driver education programs, machine operator training, and law enforcement and security personnel training programs. Fortunately, for many people, constant vigilance in dangerous environments can, to some extent, make up for a lack of perception of danger.
