Association of lucid dreaming frequency with Stroop task performance.

Lucid dreaming involves the attentional skill of having metacognition about the dreamer's state of consciousness at the same time as being engaged in the dream scenario. A combination of two levels of cognition also occurs in the incongruent condition of the Stroop task, where there is interference between the attentional demands of a relatively difficult (color naming) and an easy (reading) task. It was thus hypothesized that frequent lucid dreamers would perform better on the Stroop task than would nonlucid dreamers. Individuals who reported having lucid dreams more than once per month (n = 15) were found to be significantly faster on the incongruent condition of the Stroop task than were occasional lucid dreamers (n = 15) or nonlucid dreamers (n = 15). The groups did not differ on the standard colored nonword control condition. Continuity in attentional ability between waking and dreaming cognition was thus found. This continuity may counteract the psychophysiologically dominant and possibly evolutionarily selected lack of self-awareness in dreams. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
