A social neuroscience approach to self and social categorisation: A new look at an old issue

We take a social neuroscience approach to self and social categorisation in which the current self-categorisation(s) is constructed from relatively stable identity representations stored in memory (such as the significance of one's social identity) through iterative and interactive perceptual and evaluative processing. This approach describes these processes across multiple levels of analysis, linking the effects of self-categorisation and social identity on perception and evaluation to brain function. We review several studies showing that self-categorisation with an arbitrary group can override the effects of more visually salient, cross-cutting social categories on social perception and evaluation. The top-down influence of self-categorisation represents a powerful antecedent-focused strategy for suppressing racial bias without many of the limitations of a more response-focused strategy. Finally we discuss the implications of this approach for our understanding of social perception and evaluation and the neural substrates of these processes.
