Pattern recognition suppression
Pattern recognition suppression can be defined as the experience of a partial to complete inability to mentally process perceivable visual information regardless of its clarity, detail and clearness. For example, although one may be able to see what is in front of them with perfect detail, they will have a reduced ability to register, label or understand what they are looking at. This can render even the most common of everyday objects as unrecognisable.
Pattern recognition suppression is most commonly directly induced by heavy dosages of antipsychotics and dissociatives. However, it can also be an indirect result of the long term memory suppression that often occurs during heavy dosages of psychedelics.
