HFRG Threat Pattern Recognition
Questions & Answers(RATED A)
research in human factor science -ANSWER what is the TPR course a product of
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
impact of sns on vision -ANSWER vasoconstriction and hormonal changes cause
distortions in vision
Sight alignment -ANSWER canting of the body which pulls a head sideways allowing
the shooter to establish site alignment with their dominant eye
motor skill classification -ANSWER fine, complex and gross
inverted u -ANSWER performance will gradually deteriorate as stress increases
incident reporting after critical incident -ANSWER there are three reports
1. is a preliminary verbal,
2. is a supplemental debrief taken after the first sleep period and
3.or final is prepared after the second sleep period
ATP/PC system -ANSWER small energy bundles that are stored in the muscles they
burn out after 10 to 15 seconds after that the officer can expect a 45% decrease in
maximum output
