The Self from the past seems like a friend: comparison between oneself and close-other, a neuroscience perspective
Tue-A8-Talk V-05
Presented by: Ilona Kotlewska
The concept of Self has inspired philosophers for thousands of years, yet, we still know very little of its emergence in our minds and brains. Every one of us has the crucial feeling of being oneself and although the changes in life occur, the feeling of oneself remains. This continuity of self-concept in time is rarely investigated with brain imaging techniques. In the talk, I will discuss the neural underpinnings of the processes that build our continuous sense of the self. Electrophysiological studies will be presented, suggesting that neural mechanisms underlying processing the information related to the past self are comparable to processing the information regarding closely-related others. The study of own-name and own-face detection revealed higher brain activity in response to the self than to famous and unknown name/face. The second study of trait adjectives evaluation showed increased brain activity to the self than to a famous person. Both studies bring a meaningful insight into the relation between past-self and close-other comparison: although the present self differs significantly from the close-other, the past-self does not. The results are discussed in the framework of extended self and incorporating closely-related others into one’s self-concept.
