the difference between reality and your experience of reality

Optical illusions

The transformation of objective data [pixels on the screen] into meaningful images is quite a thing to behold. Personal research involves beholding it from two designated perspectives: The third-person perspective of a dispassionate researcher and the first-person perspective of the subject of the research.  So take a few moments to let each image do its thing.  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 . . . .

First, the image you saw changed even though nothing changed on the screen, demonstrating that the images don’t exist on the screen.  Images are subjective phenomena created by and existing only within a living creature.  When you look at these graphics, your eye and brain transform raw optical data [the pixels] into subjective experience [the images].  A similar transformation takes place when you listen to music: The psyche creates subjective experiences (rhythms, melodies, emotional reactions, etc.) from raw auditory input (pressure waves vibrating the eardrum).  The raw data — pixels, patterns of pressure waves — is intrinsically meaningless.  Sounds, colors, patterns are phenomena that do not exist in the physical world.  Without transforming the raw data of pixels, pressure waves, etc., into subjective experience, a creature would not be able to react to the things that happen.

 You can use these illusions, along with the beautiful but ambiguous graphics on the following page, to research the transformation of the raw data that your nervous system gathers from the outside world to your particular interpretation of it.  Personal research is tricky because the subjective experience is only accessible from the first-person perspective, whereas relatively unbiased observation of cause and effect is only available from the third-person perspective of a dispassionate observer.

Notice:

  • 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.
  • 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.
