1000多名大学本科生同时被分为高度抑郁或轻度抑郁、高度焦虑或轻度焦虑，并被分配了一项通常会引发左半空间偏见的面部处理任务。在知觉不对称得分中，抑郁和焦虑与相反的偏见有关。特别是，高抑郁的学生比低抑郁的学生有更小的左半球偏差，而高焦虑的学生比低焦虑的学生有更大的左半球偏差。结果表明，抑郁和焦虑可能与半球不对称功能的不同模式有关。由于人群中抑郁和焦虑的共病率很高，这些发现证实了在检查大脑活动模式、情感和精神病理之间的关系时分离焦虑和抑郁的重要性。
More than 1,000 university undergraduates were simultaneously classified as either high or low depressed and high or low anxious and given a face-processing task that typically elicits a left hemi-spatial bias. Depression and anxiety were associated with opposing biases in perceptual asymmetry scores. In particular, high-depressed students had smaller left hemispatial biases than low-depressed students, whereas high-anxious students had larger left hemispatial biases than low-anxious students. The results suggest that depression and anxiety may be associated with different patterns of asymmetric hemispheric function. Because the rate of comorbidity of depression and anxiety in the population is high, these findings confirm the importance of separating anxiety and depression when examining the relationship among patterns of brain activity, emotion, and psychopathology.
