主导感及其在强迫症中的研究述评

Review on sense of agency and its research in obsessive-compulsive disorder

主导感(sense of agency)是个体感知到的对自身行为及行为后果的控制感。主导感的产生既基于内部的感觉运动信息,也基于动作系统以外的外部信息。寻求内部状态的代理模型(seeking proxies for internal states,SPIS)提出,强迫症(obsessive-compulsive disorder)个体会削弱对自身内部状态的访问,转而寻求外部代理,因此,强迫症患者的主导感较低。未来研究可以尝试将主导感分解为不同的维度或通过追踪研究探索主导感降低是否能够预测强迫症的发病。

Sense of agency refers to the feeling of control over actions and their consequences,that is,“I am the initiator of my own behavior”.The sense of agency is based not only on the internal sensory and motor information,but also on the external information outside the action system.The main measurement methods include explicit measurement and implicit measurement.Researching on the sense of agency in special groups will help to further clarify the mechanism of the sense of agency.The Seeking Proxies for Internal States(SPIS)model of obsessive-compulsive disorder(OCD)posits that obsessive-compulsive individuals have attenuated access to their internal states and turn to seek external agents,which predicted the decrease of sense of agency in OCD individuals.Future research can try to decompose the sense of agency into different dimensions or explore whether the decreased sense of agency can predict the incidence of obsessive-compulsive disorder.
