Software/Resources:

grtools: R package for the analysis of perceptual independence using General Recognition Theory. Includes functions to analyze data with GRT-wIND (Soto et al., 2015). A tutorial introduction to GRT analyses using grtools can be found in this paper.


FaReT: Face Research Toolkit. A free and open-source toolkit of 3D models and software to study face perception. Includes a database of 27 identity models and 6 emotional expression models, together with software to manipulate the models in ways that are common in the face perception literature (e.g., “morphing”, “anti-faces”, "caricatures", "averaging"), obtain videos of dynamic faces, standardize irrelevant features in multiple models, and communicate with experiment software (e.g., PsychoPy) to render faces dynamically online.
