An Additional Benefit of Rapid Delivery

My teaching style, as well as my presentation style, is marked by a relatively rapid delivery.  I had favored such a style quite awhile ago for many public speaking formats as the general perception of the speaker by the audience is favorable (generally heighten perceptions of intelligence and mastery of the material). 

However, now I can justify such approaches beyond my own perceived benefit and claim that I am doing my audience a favor.  That is, those who engage the presented material will tend to be happier thanks to my public service:

In six experiments, researchers at Princeton and Harvard universities made research participants think quickly by having them generate as many problem-solving ideas (even bad ones) as possible in 10 minutes, read a series of ideas on a computer screen at a brisk pace or watch an I Love Lucy video clip on fast-forward. Other participants performed similar tasks at a relaxed speed.

Results suggested that thinking fast made participants feel more elated, creative and, to a lesser degree, energetic and powerful. Activities that promote fast thinking, then, such as whip­ping through an easy crossword puzzle or brain-storming quickly about an idea, can boost energy and mood, says psychologist Emily Pronin, the study’s lead author.
