Humans show a bias to favour information related to themselves over information related to other people. How does this effect arise? Are self biases a stable trait of the individual? Do these biases change fundamental perceptual processes?
I will review recent work from my laboratory showing that self-biases modulate basic perceptual processes; they are stable for an individual and are difficult to control; they reflect rapid tuning of brain circuits to enhance the saliency of self-related items. I discuss the implications of this work for understanding whether perceptual processes are informationally encapsulated, and whether perception changes as a function of social context.
