Bobbie, of Phoenix asks, “I was in a presentation when the presenter had a subliminal message appear on the PowerPoint. How can I make a subliminal message in my presentations?”
According to Wikipedia, “Subliminal stimuli(pronounced /sʌb lɪmɨnəl/, literally “below threshold”), contrary to supraliminal stimuli or “above threshold”, are any sensory stimuli below an individual’s absolute thresholdfor conscious perception. Visual stimuli may be quickly flashed before an individual may process them, or flashed and then masked, thereby interrupting the processing. Audio stimuli may be played below audible volumes, similarly masked by other stimuli, or recorded backwards in a process called backmasking. Introduced in 1897, the concept became controversial as “subliminal messages” in 1957 when marketing practitioners claimed its potential use in persuasion. Subsequent scientific research, however, has been unable to replicate most of these marketing claims beyond a mere placebo effect.”
Used in the right circumstances, subliminal messages can be humorous. With PowerPoint, it is very easy to create subliminal messages during a presentation.
To do so, follow these steps.
Select the slide in which you want the subliminal message to appear.
Insert the image in the slide.
Select the image and click on the “Add Effect” button on the “Custom Animation” window. See image above.
NOTE: In PowerPoint 2007, click on the “SlideShow” tab and select the “Custom Animation” from the “Animations” drop down from the “Animations” area. In PowerPoint 2003 (and earlier), select the “Custom Animation” item from the “SlideShow” menu.
Click on the “Flash Once” option on the “Entrance” menu.
HINT: If the “Flash Once” option is not available, click on the “more effects” item to open the entire menu of options. Click on the “OK” button to return to the “Custom Animation” window.
View the animation effects and edit as needed.
You may opt to have the animation viewed at a faster rate. If needed, click on the “Speed” drop down in the “Custom Animations” window and select a slower or faster speed.
You have now created a “subliminal message” for your audience to view and possibly get a chuckle.
Have fun with this PowerPoint Tip. Subliminal messages can be powerful and humorous. Use them for your enjoyment, and others.
