To this end, we used multivariate pattern analysis to examine an <a href=\"http:\/\/en.wikipedia.org\/wiki\/Functional_magnetic_resonance_imaging\" target=\"_blank\">fMRI<\/a> dataset that was collected while participants assigned to mixed-race groups categorized own-race and other-race faces as belonging to their newly assigned group. Whereas conventional univariate analyses provided no evidence of biased race-based responses in the fusiform gyri or early visual cortex, multivariate pattern analysis suggested that race was represented within these regions. Moreover, race was represented in the fusiform gyri to a greater extent than early visual cortex, suggesting that the fusiform gyri results do not merely reflect low-level perceptual information (e.g., color, contrast) from early visual cortex. The findings indicate that patterns of activation within specific regions of the visual cortex may represent race even when overall activation in these regions is not driven by racial information.<\/p>\n<p>Read\u00a0the entire\u00a0article <a href=\"http:\/\/www.psych.nyu.edu\/vanbavel\/lab\/documents\/Ratner.etal.2012.SCAN.pdf\" target=\"_blank\">here<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Is race erased?
