INVESTIGATING THE DIMENSIONALITY OF TORR: A REPLICATION STUDY

Although Relational Reasoning (RR) is regarded as an extraordinarily important research field, relatively little is known about its measurement. The Test of Relational Reasoning (TORR) is a non-verbal instrument claimed to measure four forms of RR: analogy, anomaly, antinomy, and antithesis. At the time of writing, there is only one study systematically investigating the dimensionality and psychometric properties of TORR within the IRT methodology of the original authors, which does not give unambiguous result. The goal of this paper is to replicate the original study on an independent Russian sample of participants in the paradigm of Rasch measurement. Despite several limitations, the independent investigation of TORR dimensionality supports the results of the original study.
