Abstract

Firearm shooting performance training rightfully focuses on shooting accuracy; however, additional foci should include decision processing speed and reaction time associated with decision making to avoid reaction-only based shooting responses. While advancements in realistic training environments attempt to mimic "real-world" situations, many remain largely anticipatory or subject to a speed-accuracy trade-off (SAT). The purpose of this brief field trial was to demonstrate the feasibility of a random-action target system (RATS) on participants' shooting performance (i.e., accuracy, omission, and commission rates) among a convenience sample of six retired police officers and competitive shooters (age range: 45-58 years, mean age = 52.5 ± 5.89). Observational data were gathered from a single-day, three-round trial to test shooting accuracy and shooting errors when shooters were unable to anticipate target appearance location and target exposure speed. In Trial 1, the target exposure time was 0.5 s, which increased to 0.7 s in Trial 2, and decreased back to 0.5 s in Trial 3. Shooting accuracy generally increased, while omission and commission generally decreased, when shooters were presented with targets exposed for longer durations. From Trial 1 to Trial 3 (both trials with 0.5 s target exposures), shooters showed higher median accuracy rates, lower median omission rates, and lower median commission rates. Findings suggest that a non-anticipatory, RATS holds promise for improving shooting performance and offset SAT among shooters with firearm experience. However, additional trials are needed with the RATS to replicate these findings among a larger and more diverse set of participants, who train with the RATS consistently, over longer durations.

摘要

枪支射击性能训练理所当然地侧重于射击精度;然而,其他重点应包括决策处理速度以及与决策相关的反应时间,以避免仅基于反应的射击反应。虽然逼真训练环境的进步试图模拟“现实世界”的情况,但许多环境在很大程度上仍然是预期性的,或者存在速度-精度权衡(SAT)。这项简短的现场试验的目的是在六名退休警察和竞技射手(年龄范围:45 - 58岁,平均年龄 = 52.5 ± 5.89)的便利样本中,证明随机动作目标系统(RATS)对参与者射击性能(即精度、漏报率和误报率)的可行性。观察数据来自为期一天的三轮试验,以测试射手在无法预测目标出现位置和目标暴露速度时的射击精度和射击误差。在试验1中,目标暴露时间为0.5秒,在试验2中增加到0.7秒,在试验3中又降至0.5秒。当向射手呈现暴露时间更长的目标时,射击精度总体上有所提高,而漏报和误报总体上有所下降。从试验1到试验3(两次试验目标暴露时间均为0.5秒),射手的中位数准确率更高,中位数漏报率更低,中位数误报率更低。研究结果表明,对于有枪支使用经验的射手,非预期性的随机动作目标系统有望提高射击性能并抵消速度-精度权衡。然而,需要使用随机动作目标系统进行更多试验,以便在更大、更多样化的参与者群体中复制这些结果,这些参与者要持续使用随机动作目标系统进行更长时间的训练。
