HFRG THREAT PATTERN RECOGNITION QUESTIONS
AND VERIFIED ANSWERS
research in human factor science ☑️☑️ what is the TPR
course a product of
human factor sciences ☑️☑️ The study of human capabilities
and human limitations within a specific domain
.37 seconds or 1/3 of a second ☑️☑️ the fastest draw time as
identified by the Hontz, Siddle and HFRG study
50% ☑️☑️ 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 ☑️☑️ how long it takes an officer
to engage in a situation with accuracy
threat pattern recognition ☑️☑️ 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 ☑️☑️ 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 ☑️☑️ is the study of human capabilities and
human limitations within a specific domain
, Page | 2
high risk human factors ☑️☑️ The study of human capabilities
and limitations in a high risk environment that is dynamic fluid
time compressed and life-threatening
51.9% ☑️☑️ percentage of officers killed in 0 to 5 feet from
their assailant from study in 2001-2012
19.2% ☑️☑️ percentage of officers killed 6 to 10 ft from their
assailant in a study done from 2001 to 2010
Corticle ☑️☑️ also known as the attentive system, 0.33
second cognition
Subcorticle ☑️☑️ also known as the pre-attentive It takes
point 0.012 second cognition
parasympathetic nervous system and sympathetic nervous
system ☑️☑️ The ANS is divided into two branches
The parasympathetic nervous system or PNS ☑️☑️ allows us
to rest and digest
The sympathetic nervous system or SNS ☑️☑️ releases
cortisol into the body, this provides the ability to either fight or
flight
homeostasis ☑️☑️ The balance between the fight and flight
syndrome and the rest and digest syndrome
four triggers for the SNS ☑️☑️ objective threat perceptions,
objective fear perceptions, physical exhaustion, and startle a
response
, Page | 3
physiological changes caused by SNS activation ☑️☑️ an
increased adrenal activity, vascular flow redirected, contour of
the eyelids and pupils become dilated, auditory exclusions
adrenal activity ☑️☑️ drives the heart rate from 60-80 beats
per minute to over 200 beats per minute causing respiration to
increase
vascular activity ☑️☑️ vassal constriction, which is a lack of
circulation, causes cold hands
perceptual narrowing ☑️☑️ 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 ☑️☑️ vasoconstriction and hormonal
changes cause distortions in vision
Sight alignment ☑️☑️ canting of the body which pulls a head
sideways allowing the shooter to establish site alignment with
their dominant eye
motor skill classification ☑️☑️ fine, complex and gross
inverted u ☑️☑️ performance will gradually deteriorate as
stress increases
incident reporting after critical incident ☑️☑️ there are three
reports
1. is a preliminary verbal,
2. is a supplemental debrief taken after the first sleep period
and
