Why do African Americans have this amygdala response?
“One theory,” Lieberman said, “is that people are likely to pick up the stereotypes prevalent in a society regardless of whether their family or community agrees with those stereotypes. Several social psychologists have found evidence for this view. From an early age, cultural views, media portrayals and even the body language of authority figures may train our brains, whether we consciously agree or not.” Previous research has shown that Caucasians show an increased amygdala response to African American photos to the extent that they hold nonconscious negative attitudes towards African Americans, Lieberman said. Co-authors on the study are Johanna Jarcho, a UCLA graduate student in Lieberman’s laboratory; UCLA graduate student Naomi Eisenberger; Susan Bookheimer, professor of psychiatry and biobehavioral sciences at UCLA’s David Geffen School of Medicine; and Ahmad Hariri, assistant professor of psychiatry at the University of Pittsburgh School of Medicine and a former UCLA graduate s
