Presentation
Taking the Time to Reflect on Perception Response Time
SessionF1: Forensic Human Factors
DescriptionPerception Response Time (PRT) has a long history across multiple fields. Over time, however, different fields use the term differently. While everyone accepts that people require time before responding to events, the issue of how to apply PRT forensically to make valid and logical forensic conclusions is often a point of contention.
We will review these differences and clarify how they comport with the long history of data.
Importantly, a perception response time begins when it is possible to see something, not when it is seen. The historical origin of PRT was necessitated by the impossibility of knowing the instant when someone sees something – an unobservable event. It is only possible to present a stimulus and observe behavior subsequent to the instant something is seen.
In addition, with PRT as an exemplar, we will revisit the limitations on forensic conclusions of the variable nature of all human parameters.
