Summary
AI-generated from the abstractA new questionnaire, the Six-Dimensional Visual Hallucination Questionnaire (6D-VHQ), was developed to systematically measure the content of visual hallucinations induced by psychedelics and stroboscopic light. The tool assesses six dimensions of visual experiences, providing a standardized method for quantifying and comparing hallucinatory content across different induction methods. This allows for more precise characterization of visual phenomena in research settings.
