A group of UMass Amherst psychology researchers including PhD Candidate Adrian Rivera-Rodriguez, Senior Research Fellow Ahren Fitzroy, and Professors Nilanjana Dasgupta and Lisa Sanders examined how anger effects attention, inhibition, and error processing during a weapon identification task. Two groups of participants in the study, one displaying neutral emotion and another made to feel angry, were quickly shown an image of a Black or White, male or female face followed immediately by an image of either a weapon or harmless object. Participants were then prompted to identify the object.
