This repository contains a basic mental rotation task using materials from Ganis & Kievit (2015).

Ganis, G. and Kievit, R.A., 2015. A New Set of Three-Dimensional Shapes for Investigating Mental Rotation Processes: Validation Data and Stimulus Set. Journal of Open Psychology Data, 3(1), p.e3. DOI: http://doi.org/10.5334/jopd.ai

The experiment uses a 2 (rotation: 50 degrees, 150 degrees) x 2 (match: same, different) within subjects design.

Participants view 48 pairs of images of 3D shapes and respond (forced binary choice) whether the images depict the same shape or different shapes (when rotated).

This experiment was built using _magpie.
