Dental students commit many errors when diagnosing radiographs. To improve performance, students were asked to compare radiographs (with and without disease or with the same disease); relevant structures were highlighted in the radiographs. In a crossover design, students were randomly assigned to two groups differing in training order: Students in the peripheral-central-group (N = 39) were first trained to detect anomalies in the periphery before receiving training on anomalies in the center; the trainings in the central-peripheral-group (N = 39) were reversed. We measured detection rates and gaze behavior before and after each training. The detection rates after the first training revealed differences in line with our expectations; moreover, when accounting for varying difficulty of the tests sets there were within-groups improvements in the peripheral-central group. Unexpectedly, the gaze behavior was unaffected by the intervention. We discuss shorter learning times and sequence effects as potential causes for our findings.

比较射线照片与信号改善牙科学生的异常检测：一项眼动追踪研究

牙科学生在诊断 X 光片时会犯许多错误。为了提高成绩，学生们被要求比较 X 光片（有无疾病或有相同疾病）；射线照片中突出显示了相关结构。在交叉设计中，学生被随机分配到训练顺序不同的两组：外围中心组（N = 39）中的学生首先接受训练以检测外围异常，然后再接受中心异常训练；中枢-外围组（N= 39) 被逆转。我们测量了每次训练前后的检测率和凝视行为。第一次训练后的检测率显示出与我们预期相符的差异；此外，当考虑到测试集的不同难度时，外围中心组的组内改进。出乎意料的是，凝视行为并未受到干预的影响。我们将更短的学习时间和序列效应作为我们发现的潜在原因进行讨论。
