In a study ” Does seeing black faces of young black boys facilitate the identification of threatening stimuli?” their hypothesis was 

“We anticipated that, as in the prior experiments, participants would have less difficulty categorizing threat-related words and more difficulty categorizing safety-related words after Black primes than after White primes. Moreover, we predicted that youth would sustain the perceived threat associated with Black men, which would result in comparable racial bias after child primes and after adult primes.”
