在常规X光片中诊断某些骨折可能是一项艰巨的任务，通常需要数年时间才能掌握。通常情况下，学生是专门训练的，以主要规则为基础的方式。我们的研究调查了学生是否可以通过知觉训练更快地学习诊断股骨近端颈骨折，而不必学习一套明确的规则。139名没有接受过医学或放射学培训的学生被展示了一系列右髋关节的平片X射线图像，并要求每个图像指出是否存在骨折。学生们被告知他们是否正确，以及任何骨折的位置，如果存在的话。没有其他反馈。能力较强的学生在不到一个小时的培训中就达到了与委员会认证的放射科医生相同的准确度。令人惊讶的是，当训练集被构建为过度代表参与者发现更难分类的图像类型时，感知学习减少了。相反，相对于显示相同数量的独特图像，重复训练图像并没有降低训练后的性能。知觉训练是帮助新手学习在X光图像中识别髋部骨折的有效方法，应补充目前的学生教育计划。
Diagnosing certain fractures in conventional radiographs can be a difficult task, usually taking years to master. Typically, students are trained ad-hoc, in a primarily-rule based fashion. Our study investigated whether students can more rapidly learn to diagnose proximal neck of femur fractures via perceptual training, without having to learn an explicit set of rules. One hundred and thirty-nine students with no prior medical or radiology training were shown a sequence of plain film X-ray images of the right hip and for each image were asked to indicate whether a fracture was present. Students were told if they were correct and the location of any fracture, if present. No other feedback was given. The more able students achieved the same level of accuracy as board certified radiologists at identifying hip fractures in less than an hour of training. Surprisingly, perceptual learning was reduced when the training set was constructed to over-represent the types of images participants found more difficult to categorise. Conversely, repeating training images did not reduce post-training performance relative to showing an equivalent number of unique images. Perceptual training is an effective way of helping novices learn to identify hip fractures in X-ray images and should supplement the current education programme for students.
