Folks are talking about something called the "Implicit Association Test," or IAT. The discussion I saw on television focused only on how Blacks, whites and Asians - in the U.S. I think? - perceived Blacks and whites. There seems to have been no test or discussion of how the same groups perceive Asians, compared to their perceptions of, say, ("non-Hispanic") whites compared to American Indians, or Latinos/Hispanics who are people of color (which seems the vast majority of Latinas/os. I'd like to address this when I have more information and time. The IAT also raises issues of the transmission and 'contagiousness' of perceptions including some perceptions of "race" as well as how perceptions - positive and negative - spread and are spread deliberately, and what we can do about this when we take responsibility and choose to change images we're promoting.
