Multinomial process tree models of control and automaticity in weapon misidentification

When primed with a Black face, people are more likely to misidentify a non-weapon as a weapon. Weapon misidentification may hinge on the distinction between controlled and automatic processes. Various relationships between controlled and automatic processes are cast in the form of five multinomial process models, which are illustrated and compared. It is shown that variants of the traditional Process Dissociation model and the Stroop model are nested within the Quad-Model. Across four different studies, various complexity corrected model performance measures converged to support the Process Dissociation account. This account suggests that the automatic association between race and weapons is subordinate to controlled processing. More generally, these results suggest that the weapon-bias might be alleviated without interventions that directly target stereotypes. (C) 2008 Elsevier Inc. All rights reserved.
