Abstract

In Expt. 1, research by Henley & Dixon (1974) was replicated. Two experimental groups (n = 8 each) received subliminal words to right ear and 8 min of music to left ear or vice versa. Each group had its own control (n = 8 each) with only music to one ear. Categorization and ranking of imagery reported, as well as performance on a checklist containing critical, associated, and non-related words, showed that emergence was greater with words to right ear than with no words. There was no difference between experimental and control groups with words to left ear. In Expt. 2, music was eliminated, and subjects received subliminal words to right ear (n = 8) or no words. A significant difference between groups was found when reported imagery was ranked as to emergence, and on checklist, but not when reports were categorized by judges.
