Examining the relationship between subclinical levels of social anxiety and the rubber hand illusion.

An embodied sense of self allows individuals to acquire moment-to-moment insight regarding the relationship between themselves and their environment. Fundamental to this experience is information regarding body ownership and self-location, which can inform both intrapersonal and interpersonal functioning. Although it is well documented that variation in mental health symptoms can impact the accuracy of bodily self-perception, little research has, to date, explored the influence of social anxiety on the embodied self. To address this issue, here we propose to examine the impact of social anxiety on the rubber hand illusion (RHI), a procedure which can distort perceptions of body location and ownership. Related literature points to competing predictions relative to how symptoms of social anxiety potentially impact susceptibility to the RHI. In the current manuscript we present the results of a pilot study indicating a positive relationship between the strength of the RHI and social anxiety, and detail a proposed registered report that seeks to replicate and extend this experiment.
