分类和多线索判断是类似的任务，但这两个领域的有影响力的模型在计算、过程和它们所暗示的神经基础方面是不同的。在分类中，经常强调范例记忆，而多线索判断通常是根据训练中抽象的线索的整合来解释的。在 3 个实验中，作者调查了这些结论是源于过程中的真正差异，还是不同研究方法的偶然结果。结果显示，当标准从二元变量变为连续变量时，特别是对于概率变量，个体差异很大，并且从范例记忆到线索抽象的转变。标准。人们似乎在这两项任务中在性质不同的过程之间切换。
Categorization and multiple-cue judgment are similar tasks, but the influential models in the two areas are different in terms of the computations, processes, and neural substrates that they imply. In categorization, exemplar memory is often emphasized, whereas multiple-cue judgment generally is interpreted in terms of integration of cues that have been abstracted in training. In 3 experiments the authors investigated whether these conclusions derive from genuine differences in the processes or are accidental to the different research methods. The results revealed large individual differences and a shift from exemplar memory to cue abstraction when the criterion is changed from a binary to a continuous variable, especially for a probabilistic. criterion. People appear to switch between qualitatively distinct processes in the 2 tasks.
