reality is different than your experience of reality

Optical illusions

Images don’t exist in the objective world. Optical illusions illustrate that you, the perceiver, create them from the meaningless pixels on the screen. Personal research involves observing this extraordinary transformation from two designated perspectives: The third-person perspective of a dispassionate researcher and the first-person perspective of the subject of the research. So give yourself a few moments to pay attention to the experience of the subject and then to the observations and conclusions of the researcher. The first graphic, for example, can be perceived as a pretty girl or as birds tending a nest. [Select an image for more about it.] After you’ve personally experienced the illusions and have observed yourself experiencing them, come back here and read on.


Notes for the research team:

  • As the researcher, note that there is no “true” interpretation of the array; the images the subject creates are fictions, and one is no more valid than another.
  • As the subject, notice that the first time your interpretation of the pixels changed, you realized the original image was only one of several possible interpretations of what you were looking at, which means that your initial judgment about what you were seeing was premature — you were taken in by the illusion.
  • As the subject, you may also notice that you can intentionally shift your interpretation or let the shift happen on its own.
  • Notice that the images you saw changed even though nothing changed on the screen, which demonstrates that the images don’t exist on the screen. You created the Images from the raw visual data on the screen [the pixels]. A similar transformation takes place when you listen to music: The psyche creates subjective experiences (rhythms, melodies, emotional reactions, etc.) from the raw auditory input (pressure waves of air vibrating the eardrum). Sequences of pressure waves contain information, but it is qualitatively different than the information carried by music or spoken words; likewise, the pixels on this, and especially the next, page just sit there without beauty or meaning until a nervous system like yours transforms them into fabulous phenomena.
