Visual Imagery's Impact on Perception

  • Joel Pearson's binocular rivalry experiment revealed that imagining an image before viewing it through goggles can influence what we see.
  • When presented with different images to each eye, the brain typically switches between them.
  • However, imagining one of those images beforehand, biases our brain's attention to showing us that exact image.
  • The extent to which the imagined image impacts the viewed result depends on someone's visual imagery skills.
  • The experiment provides a measurable approach to how visual imagery and perception interact.
