Abstract:
The current research aims to investigate what factors influence whether adults detect a change between social partners in a brief interaction. In two experiments, we examined whether locale diversity, a stranger’s marginalized status, and congruence influenced the likelihood of being differentiated. Using a change blindness paradigm, an experimenter approached pedestrians asking for directions, then surreptitiously changed places. After the switch, we measured whether pedestrians noticed if the person had changed. In Experiment 1, noticing rates were significantly lower for confederates belonging to a minority compared to confederates, but only in the more homogenous location and not in the highly diverse location. In Experiment 2, pedestrians were least likely to detect a change when confederates belonged to a religious minority.
