The valid assessment of reasoning ability is paramount for studies on the structure of intelligence and on its cognitive, biological and social correlates. A valid assessment does not only imply homogeneity of the items in a given test but preferably also their tau-equivalence. The latter is often hard to achieve – even for homogeneous reasoning tests. Controlling for method effects, however, can improve the assessment. In the current study, 273 participants completed two new and open-access online-tests of reasoning ability – the Figural Matrices test (Kyllonen et al., 2019) and the Figural Analogy test (Bloom & Holling, 2018). Confirmatory factor analyses revealed that an essentially tau-equivalent measurement model described the data poorly for both tests. The correlation between the two latent variables was merely acceptable given that the same construct was assessed (r=.56). However, considering the item-position effect (IPE) as a second latent variable with linearly increasing factor loadings improved the fit of both measurement models and allowed for describing reasoning ability as a latent variable with constant factor loadings. Thus, the measurements of reasoning ability had now the beneficial characteristics of tau-equivalence. After controlling for the IPE, the correlation between the two representations of reasoning ability increased to r=.72 indicating improved convergent validity. The two latent variables representing the IPE in the two tests did not significantly correlate. This opens an interesting debate on the task-specificity of the IPE given its most common interpretation as a reflection of the continuous learning of underlying rules from item to item.
