Racial prejudice, belief similarity, and human aggression

Out of 66 undergraduates administered a scale designed to measure racial prejudice, 16 male Caucasians scoring above the median and 16 male Caucasians scoring below the median later interacted in a competition situation with an attitudinally similar or an attitudinally dissimilar black stimulus person. The competition situation was such that the Ss had the opportunity to aggress against their opponent using electric shock. The results indicated that highly prejudiced attitudes were related to high aggression scores. It was also observed that the attitudinal similarity variable interacted with the prejudice variable during the initial stages of the aggressive interaction.
