Gaze Control and Tactical Decision-Making Under Stress in Active-Duty Police Officers During a Live Use-of-Force Response.

Police officers during dynamic and stressful encounters are required to make rapid decisions that rely on effective decision-making, experience, and intuition. Tactical decision-making is influenced by the officer's capability to recognize critical visual information and estimation of threat. The purpose of the current study is to investigate how visual search patterns using cluster analysis and factors that differentiate expertise (e.

The performance during four stationary knife attacks: Implications for tactical training.

Unlabelled: With over 72,000 offenses between 2010 and 2020 in the USA, knives were the third most commonly used weapon in all violent crimes between behind personal weapons and handguns.

Purpose: Examine the performance of different stab (Thrust and overhead) and slash (Figure 8 and Reverse) knife motions to determine how long it takes to execute each motion. In addition, examine the variability in executing each motion to inform future self-defense strategies.

Police Academy Training, Performance, and Learning.

We conducted empirical analyses of training at 3 large regional police academies in the United States. We objectively examined the performance and learning of 3 classes, a total of 115 cadets, across 3 representative training approaches to defensive and control tactics. Experiment 1 examined the content and effects of single-session or block training across 8 weeks during the academy.

Further analysis of the unintentional discharge of firearms in law enforcement.

Empirical analysis of the contexts in which UDs occur in law enforcement have only recently begun to emerge. We analyzed a novel sample of UD reports (N = 171) that occurred between 1992 and 2016, collected from one non-U.S.

Toward a taxonomy of the unintentional discharge of firearms in law enforcement.

An unintentional discharge (UD) is an activation of the trigger mechanism that results in an unplanned discharge that is outside of the firearm's prescribed use. UDs can result in injury or death, yet have been understudied in scientific literature. Pre-existing (1974-2015) UD reports (N = 137) from seven law enforcement agencies in the United States of America were analyzed by context, officer behavior, type of firearm, and injuries.

Memory and the operational witness: Police officer recall of firearms encounters as a function of active response role.

Investigations after critical events often depend on accurate and detailed recall accounts from operational witnesses (e.g., law enforcement officers, military personnel, and emergency responders).

The influence of officer equipment and protection on short sprinting performance.

As advances in protective equipment are made, it has been observed that the weight law enforcement officers must carry every day is greatly increasing. Many investigations have noted the health risks of these increases, yet none have looked at its effects on officer mobility. The primary purpose of this study was to examine the influence of both the weight of officer safety equipment, as well as a lateral focal point (FP), on the stride length, stride velocity, and acceleration of the first six strides of a short sprint.

Witnesses in action: the effect of physical exertion on recall and recognition.

Understanding memory performance under different operational conditions is critical in many occupational settings. To examine the effect of physical exertion on memory for a witnessed event, we placed two groups of law-enforcement officers in a live, occupationally relevant scenario. One group had previously completed a high-intensity physical-assault exercise, and the other had not.

Performing under pressure: gaze control, decision making and shooting performance of elite and rookie police officers.

Gaze of elite (E) and rookie (R) officers were analyzed as they faced a potentially lethal encounter that required use of a handgun, or inhibition of the shot when a cell phone was drawn. The E shot more accurately than the R (E 74.60%; R 53.
