Moving While Black: Intergroup Attitudes Influence Judgments of Speed
Four experiments examined whether intergroup attitudes shape the speed with which Blacks are thought to be moving. When participants rated the speed of Black and White faces that appeared to be moving toward them, greater intergroup anxiety was associated with judging Black targets as moving more slowly relative to White targets (Experiments 1a and 1b). Experiment 2 demonstrated that this effect occurs only for approaching targets. Experiment 3 showed that this slowing bias occurs, at least in part, because of the perceived duration of time each image was moving. Such a slowing bias is consistent with the time expansion and perceptual slowing reported by people who experienced threatening events.
