Millions of dollars are spent each year by individuals seeking to improve their athletic performance. One area of visual training is the use of the tachistoscope, which measures inspection time or visual recognition time. Although the potential of the tachistoscope as a training tool has received some research attention, its use as a means of measurement or predictor of athletic ability in sports has not been explored. The purpose of this pilot study is to assess the potential of the tachistoscope as a measurement instrument by determining if a baseball player's ability to identify a tachistoscopically presented picture of a pitch is correlated with hitting performance as measured by batting average.
Using sport-specific slides, 20 subjects-all non-pitching members of the Pacific University Baseball Team-were administered a tachistoscopic test. The test consisted of identifying the type of pitch illustrated in 30 randomly ordered slides depicting a pitcher throwing four different baseball pitches. Each slide was presented for 0.2 sec. The results of the test were compared with the athlete's previous season's batting average.
A positive correlation was found between an athlete's ability to correctly identify a picture of a pitch presented tachistoscopically and batting average (r=0.648; P<0.01). These results suggest that a superior ability to recognize pitches presented via tachistoscope may correlate with a higher skill level in batting.
Tachistoscopic test scores correlated positively with batting averages. The tachistoscope may be an acceptable tool to help in assessing batting performance. Additional testing with players from different sports, different levels of ability, and different tachistoscopic times should be performed to determine if the tachistoscope is a valid measure of athletic ability. Implications may also be drawn in other areas such as military and police work.
每年都有数百万人花费大量资金用于提升运动表现。视觉训练的一个领域是使用速示器，它用于测量检查时间或视觉识别时间。尽管速示器作为一种训练工具的潜力已受到一些研究关注，但它作为运动中运动能力的测量手段或预测指标的应用尚未得到探索。这项初步研究的目的是通过确定棒球运动员识别速示呈现的投球图片的能力是否与以击球率衡量的击球表现相关，来评估速示器作为一种测量工具的潜力。
使用特定运动的幻灯片，对20名受试者——太平洋大学棒球队所有非投手队员——进行了速示测试。测试包括识别30张随机排序的幻灯片中所示的投球类型，这些幻灯片描绘了一名投手投出四种不同的棒球投球。每张幻灯片呈现0.2秒。将测试结果与运动员上一赛季的击球率进行比较。
发现运动员正确识别速示呈现的投球图片的能力与击球率之间存在正相关（r = 0.648；P < 0.01）。这些结果表明，通过速示器识别投球的卓越能力可能与更高的击球技能水平相关。
速示测试分数与击球率呈正相关。速示器可能是有助于评估击球表现的一种可接受的工具。应使用来自不同运动、不同能力水平和不同速示时间的运动员进行额外测试以确定速示器是否是运动能力的有效测量指标。在军事和警察工作等其他领域也可能得出相关启示。
