Emergence of unreported stimuli into imagery as a function of laterality of presentation: a replication and extension of research by Henley & Dixon (1974)
Journal/Book: Br J Psychol. 1979; 70: 253-8.
Abstract: In Expt. 1, the research by Henley & Dixon (1974) was replicated. Two experimental groups (n=8 each) received subliminal words to the right ear and 8 min of music to the 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 the right ear than with no words. There was no difference between experimental and control groups with words to the left ear. In Expt. 2, the music was eliminated, and subjects received subliminal words to the right ear (n=8) or no words. A significant difference between groups was found when the reported imagery was ranked as to emergence, and on the checklist, but not when the reports were categorized by judges.
