What is defined as the time from actual perception to the start of evasive action during an incident?

The correct answer is defined as Reaction Time, which is specifically the interval that elapses between a person's awareness of a potential danger and the initiation of an evasive action. This concept encompasses the immediate cognitive and physical response that follows the perception of an event or stimulus.

In an incident scenario, the individual first perceives the situation (such as an obstacle or hazard), and Reaction Time measures how long it takes from that moment of awareness to the commencement of any movement or action intended to avoid or mitigate the danger. This time is critical in emergency situations, as quicker reactions can often prevent accidents or lessen their severity.

The other terms in the set may relate to decision-making or cognitive processes but do not capture the immediate nature of the response that follows perception as comprehensively as Reaction Time. For example, Response Time is broader and includes the time taken to react fully after the decision has been made, while Processing Time might refer more to the mental processing before a response is proposed, and Decision Time emphasizes the time taken to make a decision before any action is taken.
