The paper shows that self-generated hand movements reduce perceived visual contrast and affect first-order sensitivity but not metacognitive confidence judgments.

VREX is an open-source Unity toolbox that enables researchers to create 3D virtual reality experiments for psychology and neuroscience, offering procedural room generation and experiment management.

This study investigates change blindness in 3D virtual reality environments, finding that changes in the background are less detectable than those in the foreground.
