The masked affective priming task was used as an unobtrusive measure of intergroup prejudices in a sample of German adolescents (aged 13–15). Pictures of Turks and Germans were used as masked primes that preceded positive and negative target adjectives conveying either other-relevant valence (e.g., honest, evil) or possessor-relevant valence (e.g., talented, dull). Affective priming indices (denoting relative negativity of Turkish primes) were positively correlated with the open expression of prejudices towards Turks and foreigners in general in questionnaires as well as with discriminative interaction behavior in a virtual ball-tossing game. As expected, these correlations were found only for priming indices based on other-relevant targets, thereby emphasizing the differentiation of automatic prejudice into (imputed) hostility and depreciation.
