Lucid Dreaming Frequency and Change Blindness Performance

There are reports of lucid dreaming being cued by the recognition that a dream event is bizarre from the point of view of waking life. However, for dreams in general, there is a lack of ability to notice or question bizarre occurrences. A waking-life analog of this inability is here proposed to be change blindness. In change blindness tasks, a prominent alteration to a photograph occurs repeatedly, but it is rare for these changes to be spotted immediately. It was hypothesized that lucid dreamers would perform better on change blindness tasks than would nonlucid dreamers. Contrary to the hypothesis, individuals who reported having lucid dreams more than once per month (n = 13), occasional lucid dreamers (n = 13), and nonlucid dreamers (n = 12) were found not to differ significantly on performance on 6 change blindness tasks. How the usually proficient unconscious detection of errors during waking life is disabled during dreams remains to be determined, but it does not seem from the results here to have a simple relationship with the waking-life phenomenon of change blindness.
