In Scott Berkun's Confessions of a Public Speaker, he notes:
There is a moment at every movie, symphony and lecture, right before the show starts, when the entire audience goes silent...This is called the hush over the crowd, but really it's the moment when the crowd itself first forms...And when I'm the speaker, I know that special moment is the only time I will have the entire audience's full attention....What defines how well I'll do starts with how I use the power of that moment. The balance rests on a bigger question: how will I keep people's attention after that moment is gone?
I agree with Scott and in some ways, that helps you divide your talk into two important parts: A strong start, followed by a presentation or talk that's planned to keep bringing the audience's attention up high, knowing there's plenty that will divert your listeners.
Some of this involves basic physiology. Sitting passively slows people's attention. Berkun cites research by Donald A. Bligh, whose book What's The Use of Lectures? recounts using heart-rate monitors on students in lectures. Results? Audience heart rates were at their highest at the start, falling off through the rest of the lecture. Another researcher Berkun cites, John Medina, writes in Brain Rules: 12 Principles for Surviving and Thriving at Work, Home, and School that your audience has a maximum attention span of 10 minutes. (That would be a total, not just for your beginning. Sorry.)
But Cliff Atkinson, author of The Backchannel: How Audiences are Using Twitter and Social Media and Changing Presentations Forever cuts an even finer standard for speakers and presenters, based on that technology backchannel tugging on audience members' attention. He says:
In a world in which your audience is accustomed to high-quality media at their fingertips, you need to capture their attention out of the gate. You must engage your audience within the first five slides or at least the first five minutes of your presentation.You've got the idea. Your sweet spot's a short one. Here are 4 ways to make the most of it to enhance your audience's attention:
- Start a conversation with the audience: Go beyond taking a poll of the audience, because they really want to contribute to your presentation. Ask an open-ended question related to the topic, and let them share their thoughts--or tell them you'd like to put the Q&A up front. It's a great way to get the time and information you need to calibrate your remarks. Audience members like to hear themselves and like the potential surprise their fellows can bring to a presentation.
- Enter the crowd--anywhere but the front: Moving yourself into the audience is a great tactic for building rapport and for holding attention. All eyes will follow you. Better yet, start talking with a portable microphone and by entering the crowd from the side or rear of the room, both for an added surprise and to shake up the norms of the audience.
- Don't waste precious minutes on preliminaries and throat-clearing: Forget telling them how very glad you are to be here today, how much you appreciate the invitation, that lame joke, talking about the weather, thanking the host committee or talking about yourself. (There: I just saved you three minutes.) Speakers love to back into their talks obliquely in these ways, and they're just wasting time. You can weave your bio into your presentation where it's relevant and thank the hosts with a nice note. Get right down to it.
- Craft a strong opening statement: Instead. replace those niceties with strong content: A compelling question, an odd fact, your most surprising point. Here's the time to use an unusual prop and ask the audience to guess what it is, or to suggest a strong viewpoint. Jump right in. You might try outlining a presentation as you normally would, then cutting out the first few preliminary slides or points and see where that gets you.
