A Mokken Scale Analysis of the Last Series of the Standard Progressive Matrices (SPM-LS)

In this paper, I reanalyze a dataset for a special issue of Journal of Intelligence. The analysis uses the framework of Mokken Scale Analysis (MSA), which is a non-parametric approach to relations between item responses and attributes (i.e. Item-Response Theory).

A snapshot of g? Binary and polytomous item-response theory investigations of the last series of the Standard Progressive Matrices (SPM-LS)

In this paper, we propose the use of the last series of the last series of the Standard Progressive Matrices (SPM-LS) as a viable snapshot measure of g. We provide an extensive Item-Response Theory (IRT) analysis of the instrument, based on the binary (pass/fail) and nominal (response categories) data.
