与他们在普通人群中的流行程度相比，左撇子在许多互动运动的专家领域中占有过多的比例。这项研究考察了这在多大程度上是由消极的感知频率效应造成的——也就是说，与右撇子对手进行更频繁的网球比赛，是否使人们有可能更准确地区分右撇子球员的击球动作。54名右撇子和54名左撇子男性被分成三个大小相等的小组，他们的网球技术水平各不相同（国家联赛专家、地方联赛中级选手和新手），他们完成了一项网球预期测试，在测试中，他们必须预测对手在电脑屏幕上暂时被阻挡的网球击球的后续方向。结果显示，这三组人都能更好地预测右撇子击球的方向。这支持了左撇子在专家领域的过度代表性部分是由于感知频率效应的假设。
As compared with their prevalence in the general population, left-handers are overrepresented in the expert domain of many interactive sports. This study examined to what extent this is due to negative perceptual frequency effects-that is, whether the greater frequency of tennis matches with right-handed opponents makes it possible to discriminate the stroke movements of right-handed players more precisely. Fifty-four right-handed and 54 left-handed males in three equal-sized groups of varying levels of tennis expertise (national league experts, local league intermediates, and novices) completed a tennis anticipation test in which they had to predict the subsequent direction of an opponent's temporally occluded tennis strokes on a computer screen. The results showed that all three groups were better at predicting the direction of strokes by right-handed players. This supports the hypothesis that the overrepresentation of left-handers in the expert domain is partly due to perceptual frequency effects.
