Negro children's performance on a discrimination task as a function of examiner race and verbal incentive

A study to determine the differential effect of Negro and white examiners on the performance of 324 rural Negro school children on an oddity discrimination task under the variables of grade level (2, 6, 10), intelligence level (high, medium, low), and experimental incentive condition (praise, blame, control). Results indicated significant effects from examiner race, experimental incentive, and the interaction between the 2, as well as their combined interaction with grade level. It was the Negro Ss' reaction to blame under Negro examiners which differentiated their performance from that of white Ss under white examiners.
