High velocity human factors


High velocity human factors

High Velocity Human Factors (HVHF) is a paradigm in the human factors sciences that specifically studies human performance in mission critical domains (MCD), such as military combat, law enforcement, fire fighting, etc., when it experiences nonequilibrium. The domain in the human factors standpoint is said to experience nonequilibrium when the situation is perceived by the human agent as being volatile, uncertain, complex and ambiguous. This is usually accompanied by stress caused by time pressure and emotional reactions (high stakes, little time)inherent to the event or situation [Rahman, M. (2007a). High Velocity Human Factors: Human factors in mission critical domains in Nonequilibrium. "In Proceedings of the Human factors and Ergonomics 51st Annual Meeting (pp.273-277)." Santa Monica CA: Human Factors and Ergonomics Society] . A major component of HVHF theory is informed by the emotional modulation of cognition in the context human-systems interaction. [Rahman, M. (2006). Affective factors: Model of cognition under emotional states. "Proceedings of the Human Factors and Ergonomics Society 50th Annual Meeting (pp.472-476)." Santa Monica, CA: Human Factors and Ergonomics Society.]

The HVHF analyzes human performance by positing three dimensions:
# Velocity differential (lag in information processing between situational demands and capacity of the human agent)
# Psychophysiological reactions (cardiac defense, attentional tunneling, functional decortication, etc.)
# Decision making (heuristics, recognition-primed decision making)

A discourse on the theory and practice of HVHF for the law enforcement domain has been developed and published to inform the design of products and systems for police. [Rahman, M. (2007b). A discourse of law enforcement psychobehaviors: Informing design from displays in ethology to high velocity human factors. (Tech Report DHF-KFM-1). Plantation, FL: Design Integration, Motorola]
