Experimental conditions

Lower class	Middle class	Upper-class	Objects
Black	Black	Black	Pleasant
White	White	White	Unpleasant
e.g. homeless people, people with worn-out clothing	e.g. people barbecuing, having a picnic in casual clothing	e.g. people wearing upscale clothing and jewelry, people in front of a sports car or a luxury yacht	e.g. spider, snarling dog, birthday cake, flowers

Note: There are 25 pictures per condition (e.g. 25 pictures of Black middle-class people) in Experiment 1 (the neuropsychological study) and 24 pictures per condition in Experiment 2—the functional MRI study (in order to be able to equally distribute pictures across experimental blocks).
