Well, you didn't mention anything at all about dictators in your original
posting (though I see the implication in the very last sentence of that
article), so it's hard to guess what's at odds with your topic.
Some examples of subtle changes in behavior that I had in mind might be:
* increased alertness resulting from intake of caffeine
* reduction in pain sensitivity resulting from intake of aspirin

Some other examples:
* Very low frequency sound waves (in the range of 10-30 Hz, if I remember
correctly) that are below the threshold of human hearing can cause nausea
and other discomfort in people. Assuming such vibrations are not so
strong that a person feels them on their body, then, since they are below
the threshold of hearing, this would not be going through the 5 senses.
* It turns out people are sensitive to the amount of daylight that they
receive in a diurnal cycle. During the winter season, many people
experience depression because of the reduced amount of daylight. This is
not a good example because it relies on light sensitivity (i.e., vision),
but it's not a direct perceptual manipulation, and it effectuates a subtle
change in behavior.
I'm sure there must be others. Again, these may not be the kind of thing
you meant in your original posting.
