matriKS: An R package for rule-based automatic generation of Raven-like matrices

Raven-like matrices are widely used to evaluate human intelligence and abstract reasoning. However, few resources are available for automatically generating them. Some of these resources (e.g., Corvus) are hardly customizable unless one has medium-high expertise in JavaScript, while others (e.g., the IMak package in R) are mostly focused on figure analogies based on the rotation of different objects. The ideal solution would be an open-source and easy-to-use software that implements different sets of rules for the automatic generation of Raven-like matrices. This talk presents “matriKS”, an R package for the automatic generation of Raven-like matrices, available on GitHub at https://github.com/OttaviaE/MatriKS. The package implements different sets of rules, from the most basic ones (i.e., visuo-spatial rules like changes in size and/or orientation) to the most complex ones (i.e., logic rules based on inferential and inductive reasoning), and allows the users to concatenate them with different directional logics (i.e., horizontal, vertical, diagonal logics). Different matrices have been generated with the matriKS package and they have been administered to a sample of Italian children (age 4-11). Validation of the matrices has been conducted via Rasch model analyses and it also considered the rules used for generating them and the different schooling levels.
