| Abstract: Use of the Implicit Relational Assessment Procedure (IRAP) has flourished since its development as the first behavioral measure of relational responding. Variations in format, method, and analytic strategy have supported rapid development and adaptation of the procedure. The papers in this symposium consider 1) the effects of procedural variations on IRAP performance, 2) the validity of the IRAP following interventions designed to disrupt patterns relational responding, and 3) the stability of the IRAP with repeated administrations. Implications for continued adaptation and standardization of the procedure will be discussed. |

| When Red is a Shape: Challenging the Stability of Equivalence Classes with Laboratory-Based Procedures. |

| Abstract: The current study examined the impact of a variety of conditional discrimination procedures on the stability of equivalence classes of colors and shapes. Equivalence responding was measured with the Implicit Relational Assessment Procedure (IRAP) before and after encountering either direct countertraining or an indirect disruption procedure. The potential clinical implications of the results will be discussed. |

| One More Time: An Examination of the Stability of IRAP Performance over Repeated Administrations. |

| Abstract: Many have expressed interest in developing a measure of relational responding that is sensitive to behavioral variability at the level of the individual. The IRAP has been used in this way several times, as a measure of patterns in relational responding pre- and post-intervention. The use of the IRAP in this way assumes the reliability of the IRAP. The current study examines the stability of IRAP performance over repeated administrations both in terms of psychometric evaluations of reliability and stability of IRAP effects at the level of the individual. |
