据报道，与健康志愿者相比，抑郁症患者在“费力”的认知功能上存在缺陷，但并非毫不费力。为了验证重度抑郁症的费力性认知缺陷不仅仅是精神疾病或住院治疗的功能这一假设，我们对17名重度情感障碍住院患者和17名住院精神病对照患者进行了费力性认知任务和不费力性认知任务。在需要付出努力的任务上，抑郁症患者的表现明显比对照组差。两组在这项毫不费力的任务上没有差异。这些发现表明，与非抑郁症患者相比，抑郁症患者在执行需要努力的认知任务时受损。
Depressed patients have been reported to have deficits in "effortful," but not effortless, cognitive functions compared to healthy volunteers. To test the hypothesis that the effortful cognitive deficits in major depression are not simply a function of psychiatric illness or hospitalization, we administered both effort-demanding and effortless cognitive tasks to 17 inpatients with major affective disorder and 17 hospitalized psychiatric controls. The depressed patients performed significantly more poorly than the controls on the effort-demanding task. The groups did not differ on the effortless task. These findings suggest that depressed patients are impaired in performing effort-demanding cognitive tasks compared to nondepressed psychiatric patients.
