被诊断为季节性抑郁症(MDD-SAD)、非季节性抑郁症(MDD)的患者和对照组完成了改良的Stroop任务，观看了冬季和夏季的内容场景，同时记录了皮肤电导水平。MDD-SAD组和MDD组的参与者用颜色命名黑色和抑郁的内容词的时间比对照组长；然而，MDD组的人用颜色命名所有单词的时间比对照组长。在对冬季场景的反应中，MDD-SAD组的个体比MDD组和对照组的个体表现出更高的显著皮肤电导反应频率和更大的皮肤电导反应幅度。这些结果增加了越来越多的关于季节性反应的文献，这表明可能存在区分季节性和非季节性抑郁的特定特征。
Individuals diagnosed with seasonal depression (MDD-SAD), nonseasonal depression (MDD), and controls completed a modified Stroop task and viewed winter and summer content scenes while skin conductance levels were recorded. Participants in the MDD-SAD and MDD groups took longer than controls to color name dark and depressive content words; however, individuals in the MDD group took longer than controls to color name all words. In reaction to winter scenes, individuals in the MDD-SAD group exhibited a greater frequency of significant skin conductance responses and greater amplitude of skin conductance responses than individuals in the MDD and control groups. These results add to a growing literature on seasonal reactivity which suggests that there may be specific features that distinguish seasonal and nonseasonal depression.
