HFRG Threat Pattern Recognition Exam Questions and Answers 2024

what is the TPR course a product of - research in human factor science The study of human capabilities and human limitations within a specific domain - human factor sciences the fastest draw time as identified by the Hontz, Siddle and HFRG study - .37 seconds or 1/3 of a second what percent of the victim officers were within 0 to 5 ft of the assailant In the (FBI FLETC research PPCT/HFRG research study) - 50% how long it takes an officer to engage in a situation with accuracy - 1.9 seconds to 2.4 seconds a system that examines the patterns associated with an assault or lethal assault and engineers a tactical solution based on science and motor performance - threat pattern recognition research indicates officers who have received proper threat pattern recognition training__________ their reaction time during a deadly force assault and enhance their position - decrease is the study of human capabilities and human limitations within a specific domain - human factors The study of human capabilities and limitations in a high risk environment that is dynamic fluid time compressed and life-threatening - high risk human factors percentage of officers killed in 0 to 5 feet from their assailant from study in .9% percentage of officers killed 6 to 10 ft from their assailant in a study done from 2001 to 2010 - 19.2% also known as the attentive system, 0.33 second cognition - Corticle also known as the pre-attentive It takes point 0.012 second cognition - Subcorticle The ANS is divided into two branches - parasympathetic nervous system and sympathetic nervous system allows us to rest and digest - The parasympathetic nervous system or PNS releases cortisol into the body, this provides the ability to either fight or flight - The sympathetic nervous system or SNS The balance between the fight and flight syndrome and the rest and digest syndrome - homeostasis objective threat perceptions, objective fear perceptions, physical exhaustion, and startle a response - four triggers for the SNS an increased adrenal activity, vascular flow redirected, contour of the eyelids and pupils become dilated, auditory exclusions - physiological changes caused by SNS activation drives the heart rate from 60-80 beats per minute to over 200 beats per minute causing respiration to increase - adrenal activity vassal constriction, which is a lack of circulation, causes cold hands - vascular activity 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 - perceptual narrowing vasoconstriction and hormonal changes cause distortions in vision - impact of sns on vision canting of the body which pulls a head sideways allowing the shooter to establish site alignment with their dominant eye - Sight alignment fine, complex and gross - motor skill classification performance will gradually deteriorate as stress increases - inverted u there are three reports 1. is a preliminary verbal, 2. is a supplemental debrief taken after the first sleep period and final is prepared after the second sleep period - incident reporting after critical incident 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 - ATP/PC system takes place after the ATP system has been depleted acts as an afterburner fuel, provides 45 seconds of intermediate strength and endurance - lactic acid system or LAS
