Auditory-Enabled IRAP: A technical note on expanding stimulus modalities in the Implicit Relational Assessment Procedure

The Implicit Relational Assessment Procedure (IRAP) is a latency-based tool grounded in Relational Frame Theory (RFT), used to measure the strength and probability of verbal relations. This technical note introduces the Auditory-Enabled IRAP, an adapted version of the Open Source IRAP, designed to incorporate auditory stimuli alongside the traditional visual approach. Developed using the PsychoPy® platform, this software allows researchers to explore the effects of auditory stimuli on relational responding patterns. By enabling auditory stimuli, the Auditory-Enabled IRAP broadens the scope of behavioral research, offering new opportunities to investigate the dynamics of different sensory modalities in relational tasks. The project is freely available under the GPLv3+ license, supporting further research and adaptation. This tool aims to advance the understanding of relational responding by facilitating the exploration of auditory stimulus modalities within the IRAP context.Key-words: Auditory stimuli, Relational Frame Theory (RFT), behavioral research, PsychoPy®, Implicit Relational Assessment Procedure (IRAP)
