Towards a synthetic model of own group biases in face memory

In the current work, we extend the Categorization-Individuation Model (Hugenberg, Young, Bernstein, & Sacco, 2010)—an existing model of the own race bias—to organize and explain the proliferation of own group biases in face memory. In this model, we propose that own group biases result from the coacting processes of social categorization,motivation to individuate, and individuation experience. This extended Categorization-Individuation Model affords a number of benefits. First, this model allows us to begin to consider various own group biases as manifestations a single class of phenomena, offering sensible predictions across and among biases. Further, this extended Categorization-Individuation Model makes novel predictions for how own group biases can be exacerbated and eliminated by both perceptual and motivational processes, allowing for potentially novel interventions forown group biases. Finally,we discuss a variety of open questions with regard to an extended Categorization-Individuation Model, with an eye towards framing future research questions.
