•该实验证明了抑郁症患者的抽象推理缺陷，并详细说明了可能决定这种缺陷的一些认知成分。研究对象被赋予了一个辨别学习问题，在这个问题中，可能的解决方案必须被制定出来，并针对新的信息进行测试。抑郁的受试者在任务中的表现比对照组更差。两种类型的错误——无法缩小可能的解决方案（注意力不集中）和坚持不确定的假设——阻碍了抑郁症患者的表现，但对照组没有。虽然逻辑、记忆和注意力在初级水平上完好无损，但在复杂任务中无法协调这些功能似乎是抑郁症障碍的一个重要特征。
• This experiment demonstrated abstract reasoning deficits in depressed patients and detailed some of the components of cognition that may determine such deficits. Subjects were given a discrimination learning problem in which possible solutions had to be formulated and tested against new information. Depressed subjects performed more poorly on the task than controls. Two types of errors—inability to narrow down the set of possible solutions (poor "focusing") and perseveration on disconfirmed hypotheses—hampered the performance of depressed but not control subjects. While logic, memory, and attention were intact at an elementary level, the inability to coordinate these functions in a complex task appeared to be an important feature of the depressive impairment.
