When we say that our close friends have become a part of us, we’re usually talking metaphorically.

Yet prior research has shown there is a literal sense in which this is true. For instance, we’re slower at judging whether given personality traits apply to us or our friends, compared with when judging whether traits belong to us or someone we’re not close to – it’s as if our friends’ traits and our own have somehow become shared, which makes the judgment trickier.

Similarly, in terms of brain activity, we respond to mistakes made by friends in a similar way to how we respond to our own mistakes.

Now a team led by Sarah Ketay at the University Hartford have shown how this absorption of friends into our self-concept can manifest at a visual level, affecting our ability to distinguish their faces from our own. Writing in the Journal of Social and Personal Relationships, Ketay’s team said “The present research supports the idea that close others are processed preferentially and may overlap with the self.”
