HFRG THREAT PATTERN RECOGNITION EXAM
QUESTIONS AND ANSWERS 2026
◉ human factor sciences. Answer: The study of human capabilities
and human limitations within a specific domain
◉ .37 seconds or 1/3 of a second. Answer: the fastest draw time as
identified by the Hontz, Siddle and HFRG study
◉ 50%. Answer: what percent of the victim officers were within 0 to
5 ft of the assailant In the (FBI FLETC research PPCT/HFRG research
study)
◉ 1.9 seconds to 2.4 seconds. Answer: how long it takes an officer to
engage in a situation with accuracy
◉ threat pattern recognition. Answer: a system that examines the
patterns associated with an assault or lethal assault and engineers a
tactical solution based on science and motor performance
◉ decrease. Answer: research indicates officers who have received
proper threat pattern recognition training__________ their reaction
time during a deadly force assault and enhance their position
,◉ human factors. Answer: is the study of human capabilities and
human limitations within a specific domain
◉ high risk human factors. Answer: The study of human capabilities
and limitations in a high risk environment that is dynamic fluid time
compressed and life-threatening
◉ 51.9%. Answer: percentage of officers killed in 0 to 5 feet from
their assailant from study in 2001-2012
◉ 19.2%. Answer: percentage of officers killed 6 to 10 ft from their
assailant in a study done from 2001 to 2010
◉ Corticle. Answer: also known as the attentive system, 0.33 second
cognition
◉ Subcorticle. Answer: also known as the pre-attentive It takes
point 0.012 second cognition
◉ parasympathetic nervous system and sympathetic nervous
system. Answer: The ANS is divided into two branches
◉ The parasympathetic nervous system or PNS. Answer: allows us
to rest and digest
, ◉ The sympathetic nervous system or SNS. Answer: releases cortisol
into the body, this provides the ability to either fight or flight
◉ homeostasis. Answer: The balance between the fight and flight
syndrome and the rest and digest syndrome
◉ four triggers for the SNS. Answer: objective threat perceptions,
objective fear perceptions, physical exhaustion, and startle a
response
◉ physiological changes caused by SNS activation. Answer: an
increased adrenal activity, vascular flow redirected, contour of the
eyelids and pupils become dilated, auditory exclusions
◉ adrenal activity. Answer: drives the heart rate from 60-80 beats
per minute to over 200 beats per minute causing respiration to
increase
◉ vascular activity. Answer: vassal constriction, which is a lack of
circulation, causes cold hands
◉ perceptual narrowing. Answer: brain tunes into the sensory
system that provides the most relevant information at that given
second any other sensory inputs will be tuned out by the brain
