A sketch of the Implicit Relational Assessment Procedure (IRAP) and the Relational Elaboration and Coherence (REC) Model.

The current article outlines a behavior-analytic approach to the study of socalled implicit attitudes and cognition. The Implicit Relational Assessment Procedure (IRAP), the conceptual basis of which was derived from relational frame theory, is offered as a methodology that may be used in the experimental analysis of implicit attitudes and beliefs. The relational elaboration and coherence (REC) model provides a possible relational-frame account of the findings that have emerged from the IRAP. The article first outlines the research history that led to the development of the IRAP, followed by a description of the method. The REC model and how it explains a range of IRAP data are then considered. The article also outlines how both the IRAP and the REC model overlap with, and differ from, similar research found in the non-behavior-analytic literature. Key words: Implicit Relational Assessment Procedure, relational frame theory, network, elaboration, coherence, attitude
