因此，观察方法（有时称为“非操纵研究”）只需要观察已经发生的现象。例如，对于脑损伤的长期影响的研究，研究人员必须使用预先存在脑损伤的患者或他们的医疗记录。然后，观察性研究可以从小样本到一般人群进行推断，帮助神经科学家了解这种脑损伤的任何新情况。
Thus, observational methods (sometimes called “un-manipulated studies”) entail merely observing phenomena that are already underway. For a study of long-term effects of brain damage, for example, researchers have to use patients with pre-existing brain damage or their medical records. An observational study can then make inferences from that small sample to the general population, helping neuroscientists understand any new instances of that kind of brain damage.
