Aims & Scope

  • JOI is an open-access journal that aims at gathering resources to promote the study of illusion.
  • JOI defines an illusion as the perception of an object or phenomenon that is considered to be inconsistent with individual’s or group’s prior knowledge, recognition, or belief as to what the object or phenomenon should be in perception, cognition, and/or physics. Therefore, JOI focuses on perceptual illusions, cognitive illusions (e.g. magic or misunderstanding) or physical illusions (e.g. mirage or the Doppler effect). For perceptual illusions, not only visual illusions but also illusions at various sensory modalities are welcome. Trompe l’oeil as well as illusion artworks are also welcome.
  • JOI prefers phenomena to mechanisms. A single Illusion can be demonstrated in different ways even if the mechanism of the illusion is unitary. JOI does not put importance on the clarification of an underlying mechanism for an illusion. Rather, JOI calls for reports of new phenomena and/or new demonstrations/artworks that contain an illusion which deems novel, stunning, eye-catching, mind-blowing, compelling, and/or astonishing. Experimental studies on new illusions are also welcome. Review articles on new and/or known illusions are acceptable. Yet, theoretical studies that do not lead to new illusions are not welcome.
  • Rather than a hypothetical research, JOI prefers exploratory research that is usually unacceptable in the conventional style of scientific journals. The reason for our policy is because illusion works are often created based on the fruit of serendipity, not always on logical deductions from previous studies. Hence, a clear hypothesis is not required in the manuscript. On the other hand, studies based on a clear hypothesis can be submitted to the Registered reports category (see 3. Article type for detail).
