The Sorting Paired Features Task (Bar-Anan, Nosek, & Vianello, 2009)
The SPF is a flexible technique designed to measure implicit social cognition. It assesses automatic associations between concept (e.g., gender) and attribute (e.g., evaluation) categories. The SPF has four features that distinguish it from other measures of implicit social cognition. First, the SPF measures all associations in one block (unlike IAT and like Evaluative Priming). Second, the SPF requires participants to categorize two stimuli at once to a category pair. Therefore, it involves simultaneous processing of the two association units. Third, the SPF allows direct manipulation of categorization of the stimuli, measuring associatins with both focal accessible categories and non-focal not explicitly mentioned categories. Fourth, it enables separable assessments of the four association strengths involved (e.g., white-good, white-bad, black-good and black-bad). It should be noted that these assessments are not interpretable in isolation because scores for the four associations are interdependent. They only provide the relative strength of each association compared to the other three.

The sorting paired features (SPF) task measures four associations in a single response block. Using four response options (e.g., good-Republicans, bad-Republicans, good-Democrats and bad-Democrats), each trial requires participants to categorize two stimuli at once to a category pair (e.g., wonderful-Clinton to good-Democrats). Unlike other association measures, the SPF requires simultaneous categorization of both components of the association in the same trial. Providing measurement flexibility, it is sensitive to both focal, attended concepts and non-focal, unattended stimulus features (e.g., gender of individuals in a politics SPF). Three studies measure race, gender, and political evaluations, differentiate automatic evaluations between known groups, provide evidence of convergent and discriminant validity with other attitude measures, and illustrate the SPF’s unique measurement qualities.
