Research 1

• Study on the ability of subliminal messages to influence academic performance.
• 60 college students were enrolled in an undergraduate summer session law course with the experimenter-instructor for 6 weeks. In addition to the normal course of instruction, all subjects received visual subliminal stimulation before 3 out of 5 lectures each week.
• Subjects exposed to subliminal messages earned significantly higher grades than the control group. These results were viewed as consistent with findings of earlier studies on the effects of subliminal messages on schizophrenics, insect-phobics, obesity, and alcoholics.

Research 2

• A study on depressed college women (measured by the Beck Depression Inventory scores) noted that when shown a subliminal statement "Leaving Mom is wrong", subjects' depressive feelings increased.
• Schmidt, J.M. "The Effects of Subliminally Presented Stimuli on Normal Young Adults." Unpublished doctoral dissertation,, University of Southern Mississippi.
• A follow-up study on subliminal perception by Schmidt, noted that when presented with a subliminal message "I have been bad", subject' s depressive feelings increased.
• Hart, L. "The Effect of Noxious Subliminal Stimuli on the Modification of Attitudes Towards Alcoholism: A Pilot Study.".
• In a study on exposing subjects to subliminal messages and their resulting attitudes towards alcoholism, over a five-day period, subjects' attitudes towards alcoholism as measured by a questionnaire had changed significantly.
• The findings support the proposition that subliminal perception or stimuli which are not consciously perceived or directly experienced can influence attitudes.

STRONG REACTIONS TO SUBCONSCIOUS MESSAGES

• Subjects were exposed to slides of abstract geometric figures at both subliminal (i.e., 4 ms) and supraliminal exposure durations. Subjects' attitudes toward the subliminally presented stimuli became significantly more positive with repeated exposures, even when subjects were unaware that exposures had occurred.
• The experiment went on to measure attitude changes due to subliminal perception of photographs of actual persons. The results indicate that attitudes toward persons encountered in the experiment are enhanced by subliminal perception of a photograph of that person.

SUBLIMINAL EXPOSURE TO IMAGES ENHANCES THEIR APPEAL

• A subliminal letter was exposed to the left or right hemisphere of the brain for either 15 or 20 msec. Subject' s were able to guess the letter more accurately when visual presentations were made to the right side of the brain, whilst verbal recognition was more accurate when presentations to the left hemisphere.

• Study on existence of subliminal perception.
• Two groups of undergraduates were exposed to different subliminal words. One group was presented with 20 emotional words presented 10% below the detection threshold, whilst the other group was presented with 20 emotionally-neutral words.
• The subject' s heart and respiration rates were taken before and after exposure to the subliminal words.
• Research findings indicate that subjects subliminally exposed to the emotionally-charged words had significantly higher measurable readings, indicating that subliminal perception of subliminally-delivered words had taken place.
