A factorial ANOVA with three independent variables was used to examine the significance of ethnicity on facial recognition. The first independent variable was type of faces with 2 levels (adult and infant). The second independent variable is orientation of the faces with 2 levels (upright or inverted). The third independent variable is ethnicity with 7 levels (White/Caucasian, Black/African American, American Indian/Alaska Native, Latino/Hispanic, Asian, Native Hawaiian/Pacific Islander and Other). The dependent variable was the participants’ ability to recognize faces by viewing a timed slideshow with adult and infant faces. The first block included upright adult and infant faces. The second block included inverted adult and infant faces.
