Contrary to self-reports, patients with generalized anxiety disorder exhibit increased muscle tension but not autonomic hyperarousal. Under stress they tend to react autonomically in a less flexible manner than normal controls. There is only a weak relationship, and in some instances a desynchrony, between physiological changes and perception of change. The inconsistencies between self-reports of physiological states and physiological recordings can be explained by alterations of body sensations through psychological factors, predominantly expectations of and attention to bodily states, that lead to perceptual distortions.
与自我报告相反，广泛性焦虑症患者表现出肌肉紧张加剧，但自主神经高反应性并不明显。在压力下，他们自主反应的灵活性往往低于正常对照组。生理变化与变化感知之间只有微弱的关系，在某些情况下甚至存在不同步。生理状态的自我报告与生理记录之间的不一致可以通过心理因素导致的身体感觉改变来解释，主要是对身体状态的预期和关注，这会导致感知扭曲。
