Sense of ownership

From Wikipedia, the free encyclopedia

Sense of ownership (SoO), in psychology, is the feeling of identifying sensations (both internal and external) as affecting, establishing, and belonging to one's identified-self.[1] and is the pre-reflective awareness or implicit sense that one is the owner of an action, movement or thought.

In non-pathological experience, the SoO is tightly integrated with one's "sense of agency" (SoA).

At least three different types of bodily self-experiences can be experimentally identified as separable processes: self-identification (i.e. ownership of one's bodily sensations), self-location (i.e., the experience of self situated in a specific space), and first person-perspective (i.e., the loci of experiencing and perceiving reality).[1]

Self-identification

[edit]

Evidence for self-identification of body-ownership comes from cases of Body integrity dysphoria (BID) where affected individuals feel 'alienation' or over-completeness over parts of their body,[2] and somatoparaphrenia where affected individuals' deny ownership to a part or to an entire section (i.e. unilateral neglect) of their body. Research from Dilk, M.T. (2013) show associated brain areas (with decreased activity) of the premotor cortex with non-identification of body parts (in patients who exhibit BID).[2]

Self-location

[edit]

There is a large body of evidence suggesting the Temporoparietal junction (TPJ) influences body location: evidence comes from brain stimulation at the TPJ and associated out of body experiences.[3]
