训练狗辨别人类的气味并没有很好的科学依据。这项研究的目的是评价连续三个培训阶段取得的进展，并将培训结果与工作阶段的结果进行比较。六只天真的德国牧羊犬（4只雄性和2只雌性）被训练来匹配一种目标人类气味，随机放置在五种其他人类气味的队列中，在试验前直接嗅闻。在训练阶段I（空白样品中的食物气味）、阶段II（空白样品中的人类气味）和阶段III（其他人类气味中的个人气味）中，狗分别需要平均15.3、23.0和0.3次命令试验来自发地指示目标气味。在第一和第二阶段，狗的可训练性的差异，表现为与命令的试验次数显着。在连续的训练阶段，假警报（FA）和失误（MI）的平均百分比显着增加。在II期和III期，犬的FA和MI百分比存在显著差异。在连续的训练阶段，以及MI之间的FA之间的非显着的秩相关系数表明，这是很难预测的基础上，其性能在早期的训练阶段的狗未来的性能。所有的狗很容易学会执行操作性条件反射的气味阵容，但没有显示出显着的改善，在特定的训练阶段和工作阶段的检测精度。
Training of dogs to distinguish individual human scent has no well-established scientific basis. The aim of the study was to evaluate the progress made over three consecutive training phases and to compare the training results with those of the working phase. Six naive German Shepherd dogs (4 males and 2 females) were trained to match one target human scent, placed randomly in a lineup of five other human scents, with that sniffed directly before the trial. The dogs required on average 15.3, 23.0 and 0.3 trials with commands to spontaneously indicate the target scent in training phase I (food odour amidst blank samples), in phase II (human scent amidst blanks) and in phase III (individual human scent amidst other humans’ scents), respectively. The differences among dogs in their trainability, as expressed by the number of trials with commands were significant in phases I and II. The mean percentage of false alarms (FA) and misses (MI) increased significantly in consecutive training phases. The dogs differed significantly in percentage of FA and MI in phases II and III. Non-significant rank correlation coefficients between FAs in consecutive training phases as well as between MIs indicate that it is difficult to predict future performance of a dog based upon its performance in the earlier training phases. All dogs easily learned to perform operant conditioning responses in the scent lineup, but displayed no significant improvement of the detection accuracy within particular training phases and during the working phase.
