How can implicit attitudes best be measured? The Implicit Relational Assessment Procedure (IRAP), unlike the Implicit Association Test (IAT), claims to measure absolute, not just relative, implicit attitudes. In the IRAP, participants make congruent (Fat Person-Active:False; Fat Person-Unhealthy: True) or incongruent (Fat Person-Active: True; Fat PersonUnhealthy: False) responses in different blocks of trials. IRAP experiments have reported positive or neutral implicit attitudes (e.g., neutral attitudes towards fat people) in cases where negative attitudes are normally found on explicit or other implicit measures. It was hypothesized that these results might reflect a Positive Framing Bias (PFB) that occurs when participants complete the IRAP. Implicit attitudes towards categories with varying prior associations (nonwords, social systems, flowers and insects, thin and fat people) were measured. Three conditions (standard, positive framing, and negative framing) were used to measure whether framing influenced estimates of implicit attitudes. It was found that IRAP scores were influenced by how the task was framed to the participants, that the framing effect was modulated by the strength of prior stimulus associations and that a default PFB led to an overestimation of positive implicit attitudes when measured by the IRAP. Overall, the findings question the validity of the IRAP as a tool for the measurement of absolute implicit attitudes. A new tool (Simple Implicit Procedure: SIP) for measuring absolute, not just relative, implicit attitudes is proposed. Implicit attitudes are automatic evaluations that occur outside conscious awareness and are measured without requiring respondents to introspect on their feelings. Explicit attitudes in contrast are the result of deliberate introspection and controlled evaluative judgment (Greenwald & Banaji, 1995). One reason for measuring implicit attitudes is that participants may use self-presentation tactics or respond in a socially desirable manner on explicit self-reports to avoid being perceived as prejudiced. Implicit measures can also be useful in areas where participants might be unwilling to reveal personal psychological attributes or are unaware of these psychological attributes (for a review of implicit attitudes and the tools used to measure them see Gawronski & De Houwer, 2014).The current gold standard method for assessing implicit attitudes is the Implicit Association Test (IAT; Greenwald, McGhee, & Schwartz, 1998) and this tool has been increasingly used in clinically relevant areas (see https://implicit.harvard.edu/implicit/pimh/).The IAT has shown promise in predicting self-harm (Randall, Rowe, Dong, Nock, & Colman 2013), social anxiety disorders (Teachman & Allen, 2007) and suicidal ideation (Harrison, Stritzke, Fay, Ellison, & Hudaib, 2014). The current study questions the validity of a recently developed implicit measure, the Implicit Relational Assessment Procedure (IRAP; BarnesHolmes, Barnes-Holmes, Stewart, & Boles, 2010a), which has also been u...
