Generation of rule-based matrices with the matRiks package: a tutorial
Ottavia M. Epifania, Andrea Brancaccio, Pasquale Anselmi, Debora de Chiusole
TL;DR
The matRiks package is an R tool for generating customizable, rule-based matrices for psychological assessments, with realistic distractors and reproducible stimuli.
Contribution
The package introduces a flexible framework for generating matrices with transformation rules and automatically creates distractors based on common errors.
Findings
The package supports visuospatial and logical transformation rules for matrix generation.
It automatically generates distractors based on common error patterns in Raven's tests.
The tool is open-source, reproducible, and scalable for experimental and assessment purposes.
Abstract
Few resources are available for the automatic generation of Raven-like matrices. Some of them are no longer working, while others are hardly customizable without advanced programming skills. Although an R package exists for generating stimuli for psychological assessments, it currently only supports creating rotations of the same shape. The matRiks package has been developed to address the above-mentioned issues. This package generates matrices based on different types of transformation rules. Some rely on visuospatial features, such as shape, size, or orientation. Others are based on logical operations, such as set intersection or union. The package also introduces a key innovation, the automatic generation of distractors based on the common error patterns observed in Raven's tests. This allows for the construction of realistic and diagnostically meaningful response options for each…
